OpenCode – The open source AI coding agent

logicprog 2 hours ago | parent | next [-]

OpenCode was the first open source agent I used, and my main workhorse after experimenting briefly with Claude Code and realizing the potential of agentic coding. Due to that, and because it's a popular an open source alternative, I want to be able to recommend it and be enthusiastic about it. The problem for me is that the development practices of the people that are working on it are suboptimal at best; they're constantly releasing at an extremely high cadence, where they don't even spend the time to test or fix things (or even build a proper list of changes for each release), and they add, remove, refine, change, fix, and break features constantly at that accelerated pace.

More than that, it's an extremely large and complex TypeScript code base — probably larger and more complex than it needs to be — and (partly as a result) it's fairly resource inefficient (often uses 1GB of RAM or more. For a TUI).

On top of that, at least I personally find the TUI to be overbearing and a little bit buggy, and the agent to be so full of features that I don't really need — also mildly buggy — that it sort of becomes hard to use and remember how everything is supposed to work and interact.

I am more concerned about their, umm, gallant approach to security. Not only that OpenCode is permissive by default in what it is allowed to do, but that it apparently tries to pull its config from the web (provider-based URL) by default [1]. There is also this open GitHub issue [2], which I find quite concerning (worst case, it's an RCE vulnerability).

On top of that. Open code go was a complete scam. It was not advertised as having lower quality models when I paid and glm5 was broken vs another provider, returning gibberish and very dumb on the same prompt

this is what i notice with openclaw as well. there have been releases where they break production features. unfortunately this is what happens when code becomes a commidity, everyone thinks that shipping fast is the moat but at the expense of suboptimality since they know a fix can be implemented quickly on the next release.

		Openclaw has 20k commits, almost 700k lines of code, and it is only four months old. I feel confident that that sort of code base would have a no coherent architecture at all, and also that no human has a good mental model of how the various subsystems interact. I’m sure we’ll all learn a lot from these early days of agentic coding.

Probably all describe problems stem from the developers using agent coding; including using TypeScript, since these tools are usually more familiar with Js/Js adjacent web development languages.

	▲	logicprog an hour ago \| parent [-]
		Perhaps the use of coding agents may have encouraged this behavior, but it is perfectly possible to do the opposite with agents as well — for instance, to use agents to make it easier to set up and maintain a good testing scaffold for TUI stuff, a comprehensive test suite top to bottom, in a way maintainers may not have had the time/energy/interest to do before, or to rewrite in a faster and more resource efficient language that you may find more verbose, be less familiar with, or find annoying to write — and nothing is forcing them to release as often as they are, instead of just having a high commit velocity. I've personally found AIs to be just as good at Go or Rust as TypeScript, perhaps better, as well, so I don't think there was anything forcing them to go with TypeScript. I think they're just somewhat irresponsible devs.

The value of having (and executing) a coherent product vision is extremely undervalued in FOSS, and IMO the difference between a successful project in the long-term and the kind of sploogeware that just snowballs with low-value features.

		> The value of having (and executing) a coherent product vision is extremely undervalued in FOSS Interesting you say this because I'd say the opposite is true historically, especially in the systems software community and among older folks. "Do one thing and do it well" seems to be the prevailing mindset behind many foundational tools. I think this why so many are/were irked by systemd. On the other hand newer tools that are more heavily marketed and often have some commercial angle seem to be in a perpetual state of tacking on new features in lieu of refining their raison d'etre.

I recently listened to this episode from the Claude Code creator (here is the video version: https://www.youtube.com/watch?v=PQU9o_5rHC4) and it sounded like their development process was somewhat similar - he said something like their entire codebase has 100% churn every 6 months. But I would assume they have a more professional software delivery process.

I would (incorrectly) assume that a product like this would be heavily tested via AI - why not? AI should be writing all the code, so why would the humans not invest in and require extreme levels of testing since AI is really good at that?

	▲	logicprog an hour ago \| parent [-]
		I mean, I'm slowly trying to learn lightweight formal methods (i.e. what stuff like Alloy or Quint do), behavior driven development, more advanced testing systems for UIs, red-green TDD, etc, which I never bothered to learn as much before, precisely because they can handle the boilerplate aspects of these things, so I can focus on specifying the core features or properties I need for the system, or thinking through the behavior, information flow, and architecture of the system, and it can translate that into machine-verifiable stuff, so that my code is more reliable! I'm very early on that path, though. It's hard!

I’m a little surprised by your description of constant releases and instability. That matches how I would describe Claude Code, and has been one of the main reasons I tend to use OpenCode more than Claude Code.

OpenCode has been much more stable for me in the 6 months or so that I’ve been comparing the two in earnest.

▲

bakugo an hour ago | parent | prev | next [-]

Isn't this pretty much the standard across projects that make heavy use of AI code generation?

Using AI to generate all your code only really makes sense if you prioritize shipping features as fast as possible over the quality, stability and efficiency of the code, because that's the only case in which the actual act of writing code is the bottleneck.

	▲	logicprog an hour ago \| parent [-]
		I don't think that's true at all. As I said, in a response to another person blaming it on agentic coding above, there are a very large number of ways to use coding agents to make your programs faster, more efficient, more reliable, and more refined that also benefit from agents making the code writing research, data piping, and refactoring process quicker and less exhausting. For instance, by helping you set up testing scaffolding, handling the boilerplate around tests while you specify some example features or properties you want to test and expands them, rewriting into a more efficient language, large-scale refactors to use better data structures or architectures, or allowing you to use a more efficient or reliable language that you don't know as well or find to have too much boilerplate or compiler annoyance to otherwise deal with yourself. Then there are sort of higher level more phenomenological or subjective benefits, such as helping you focus on the system architecture and data flow, and only zoom in on particular algorithms or areas of the code base that are specifically relevant, instead of forever getting lost in the weeds of thinking about specific syntax and compiler errors or looking up a bunch of API documentation that isn't super important for the core of what you're trying to do and so on. Personally, I find this idea that "coding isn't the bottleneck" completely preposterous. Getting all of the API documentation, the syntax, organizing and typing out all of the text, finding the correct places in the code base and understanding the code base in general, dealing with silly compiler errors and type errors, writing a ton of error handling, dealing with the inevitable and inoraticable boilerplate of programming (unless you're one of those people that believe macros are actually a good idea and would meaningfully solve this), all are a regular and substantial occurrence, even if you aren't writing thousands of lines of code a day. And you need to write code in order to be able to get a sense for the limitations of the technology you're using and the shape of the problem you're dealing with in order to then come up with and iterate on a better architecture or approach to the problem. And you need to see your program running in order to evaluate whether it's functionality and design a satisfactory and then to iterate on that. So coding is actually the upfront costs that you need to pay in order to and even start properly thinking about a problem. So being able to get a prototype out quickly is very important. Also, I find it hard to believe that you've never been in a situation where you wanted to make a simple change or refactor that would have resulted in needing to update 15 different call sites to do properly in a way that was just slightly variable enough or complex enough that editor macros or IDE refactoring capabilities wouldn't be capable of. That's not to mention the fact that if agentic coding can make deploying faster, then it can also make deploying the same amount at the same cadence easier and more relaxing.

For serious coding work I use the Zed Agent; for everything else I use pi with a few skills. Overall, though, I'd recommend Pi plus a few extensions for any features you miss extremely highly. It's also TypeScript, but doesn't suffer from the other problems OC has IME. It's a beautiful little program.

		Big +1 to Pi[1]. The simplicity makes it really easy to extend yourself too, so at this point I have a pretty nice little setup that's very specific to my personal workflows. The monorepo for the project also has other nice utilities like a solid agent SDK. I also use other tools like Claude Code for "serious" work, but I do find myself reaching for Pi more consistently as I've gotten more confident with my setup.

The OpenCode docs suggest its possible, but it only works with their extension (not in an already open VS Code terminal) with a very specific keyboard shortcut and only barely at that.

They are not blacklisted. You are allowed to use the API at commercial usage pricing. You are just not allowed to use your Claude Code subscription with OpenCode (or any other third‑party harness for the record).

▲

KronisLV 3 hours ago | parent | next [-]

With Anthropic, you either pay per token with an API key (expensive), or use their subscription, but only with the tools that they provide you - Claude, Claude Cowork and Claude Code (both GUI and CLI variants). Individuals generally get to use the subscriptions, companies, especially the ones building services on top of their models, are expected to pay per token. Same applies to various third party tools.

The belief is that the subscriptions are subsidized by them (or just heavily cut into profit margins) so for whatever reason they're trying to maintain control over the harness - maybe to gather more usage analytics and gain an edge over competitors and improve their models better to work with it, or perhaps to route certain requests to Haiku or Sonnet instead of using Opus for everything, to cut down on the compute.

Given the ample usage limits, I personally just use Claude Code now with their 100 USD per month subscription because it gives me the best value - kind of sucks that they won't support other harnesses though (especially custom GUIs for managing parallel tasks/projects). OpenCode never worked well for me on Windows though, also used Codex and Gemini CLI.

	▲	anonym29 3 hours ago \| parent [-]
		>or perhaps to route certain requests to Haiku or Sonnet instead of using Opus for everything, to cut down on the compute You can point Claude Code at a local inference server (e.g. llama.cpp, vLLM) and see which model names it sends each request to. It's not hard to do a MITM against it either. Claude Code does send some requests to Haiku, but not the ones you're making with whatever model you have it set to - these are tool result processing requests, conversation summary / title generation requests, etc - low complexity background stuff. Now, Anthropic could simply take requests to their Opus model and internally route them to Sonnet on the server side, but then it wouldn't really matter which harness was used or what the client requests anyway, as this would be happening server-side.

Anthropic's model deployments for Claude Code are likely optimized for Claude Code. I wouldn't be surprised if they had optimizations like sharing of system prompt KV-cache across users, or a speculative execution model specifically fine-tuned for the way Claude Code does tool calls.

When setting your token limits, their economics calculations likely assume that those optimizations are going to work. If you're using a different agent, you're basically underpaying for your tokens.

Anthropic has an API, you can use any client but they charge per input/output/cache token.

One-price-per-month subscriptions (Claude Code Pro/MAX @ $20/$100/$200 a month) use a different authentication mechanism, OAUTH. The useful difference is you get a lot more inference than you can for the same cost using the API but they require you to use Claude Code as a client.

Some clients have made it simple to use your subscription key with them and they are getting cease and desist letters.

I’ve been extraordinarily productive with this, their $10 Go plan, and a rigorous spec-driven workflow. Haven’t touched Claude in 2 months.

The ability to switch models is very useful and a great learning experience. GLM, Kimi and their free models surprised me. Not the best, not perfect, but still very productive. I would be a wary shareholder if I owned a stake in the frontier labs… that moat seems to be shrinking fast.

	▲	brendanmc6 an hour ago \| parent \| next [-]
		Sure happy to share. It’s been trial and error, but I’ve learned that for agents to reliably ship a large feature or refactor, I need a good spec (functional acceptance criteria) and I need a good plan for sequencing the work. The big expensive models are great at planning tasks and reviewing the implementation of a task. They can better spot potential gotchas, performance or security gaps, subtle logic and nuance that cheaper models fail to notice. The small cheap models are actually great (and fast) at generating decent code if they have the right direction up front. So I do all the spec writing myself (with some LLM assistance), and I hand it to a Supervisor agent who coordinates between subagents. Plan -> implement -> review -> repeat until the planner says “all done”. I switch up my models all the time (actively experimenting) but today I was using GPT 5.4 for review and planning, costing me about $0.4-$1 for a good sized task, and Kimi for implementation. Sometimes my spec takes 4-5 review loops and the cost can add up over an 8 hour day. Still cheaper than Claude Max (for now, barely). Each agent retains a fairly small context window which seems to keep costs down and improves output. Full context can be catastrophic for some models. As for the spec writing, this is the fun part for me, and I’ve been obsessing over this process, and the process of tracking acceptance criteria and keeping my agents aligned to it. I have a toolkit cooking, you can find in my comment history (aiming to open source it this week).

i've been using this as my primary harness for llama.cpp models, Claude, and Gemini for a few months now. the LSP integration is great. i also built a plugin to enable a very minimal OpenClaw alternative as a self modifying hook system over IPC as a plugin for OpenCode: https://github.com/khimaros/opencode-evolve -- and here's a deployment ready example making use of it which runs in an Incus container/VM: https://github.com/khimaros/persona

		Very cool! I have been using opencode, as almost everybody else in the lab is using codex. I found the tools thing inside your own repo amazing but somehow I could not get it to reliably get opencode to write its own tools. Seems also a bit scary as there is pretty much not much security by default. I am using it in a NixOS WSL2 VM

Definitely not Wayland related, or so I doubt. I'm on wayland and never had any issues, and it's a TUI, where the terminal emulator does or does not do GPU work. What led you to that conclusion?

This issue: https://github.com/anomalyco/opencode/issues/9505

And then the official docs: https://opencode.ai/docs/troubleshooting/#linux-wayland--x11...

> Linux: Wayland / X11 issues

> On Linux, some Wayland setups can cause blank windows or compositor errors.

> If you’re on Wayland and the app is blank/crashing, try launching with OC_ALLOW_WAYLAND=1.

> If that makes things worse, remove it and try launching under an X11 session instead.

OC_ALLOW_WAYLAND=1 didn't work for me (Ubuntu 24.04)

Suggesting to use a different display server to use a TUI (!!) seems a bit wild to me. I didn't put a lot of time into investigating this so maybe there is another reason than Wayland. Anyway I'm using Pi now

This replaced Aider for me a couple months back.

I use it with Qwen 3.5 running locally when my daily limits run out on my other subscriptions.

The harness is great. Local models are just slow enough that the subscription models are easier to use. For most of my tasks these days, the model's capability is sufficient; it is just not as snappy.

	▲	cyanydeez 2 hours ago \| parent [-]
		I'm curious: I'venever touched cloud models beyond a few seconds. I run a AMD395+ with the new qwen coder. Is there any intelligence difference, or is it just speed and context? At 128GB, it takes quite awhile before getting context wall.

aimarketintel 2 hours ago | parent | prev | next [-]

One thing that makes coding agents really useful is structured data access via MCP servers. Instead of the agent trying to scrape a webpage to understand your project's context, you give it a direct API to query structured data from 9+ sources (GitHub repos, Stack Overflow questions, arXiv papers, npm packages).

The biggest bottleneck I've seen isn't the coding — it's the agent not having enough context about the ecosystem it's working in.

Anecdotal pros and one annoyance:

OpenCode is an awesome tool.

Many folks from other tools are only getting exposed to the same functionality they got used to, but it offers much more than other harnesses, especially for remote coding.

You can start a service via `opencode serve`, it can be accessed from anywhere and has great experience on mobile except a few bugs. It's a really good way to work with your agents remotely, goes really well with TailScale.

The WebUI that they have can connect to multiple OpenCode backends at once, so you may use multiple VPS-es for various projects you have and control all of them from a single place.

Lastly, there's a desktop app, but TBH I find it redundant when WebUI has everything needed.

Make no mistakes though, it's not a perfect tool, my gripes with it:

- There are random bugs with loading/restoring state of the session

- Model/Provider selection switch across sessions/projects is often annoying

- I had a bug making Sonnet/Opus unusable from mobile phone because phone's clock was 150ms ahead of laptop's (ID generation)

- Sometimes agent get randomly stuck. It especially sucks for long/nested sessions

- WebUI on laptop just completely forgot all the projects at one day

- `opencode serve` doesn't pick up new skills automatically, it needs to be restarted

▲

hungryhobbit 3 hours ago | parent [-]

You are absolutely correct that both are evil ... as are most corporations.

Still, I feel like "will commit illegal mass murder against their own citizens" is a significant enough degree more evil. I think lots of corporations will help their government murder citizens of other countries, but very few would go so far as to agree to murder their own (fellow) citizens ... just to get a juicy contract.

▲

stavros 3 hours ago | parent [-]

I see your viewpoint but, to me, "both will happily murder you but one is better because they won't murder ME!" isn't very compelling. Like, I get it, but also it changes nothing for me. They're both bad.

▲

hungryhobbit 2 hours ago | parent | next [-]

It's not about "won't murder me" it's about "won't murder their own tribe". Humans are very tribal creatures, and we have all sorts of built-in societal taboos about betraying our tribe.

We also have taboos against betraying/murdering/whatever people of other tribes, but those taboos are much weaker and get relaxed sometimes (eg. in war). My point is, it takes significantly more anti-social (ie. evil) behavior to betray your own tribe, in the deepest way possible, than it does to do horrible things to other tribes.

This is just as much true for Russians murdering Ukranians as Ukranians murdering Russians, or any other conflict group: almost all Russians would consider a Russian who helps kill Russians to be more evil than a Russian who kills Ukranians (and vice versa).

	▲	stavros an hour ago \| parent [-]

Just remember, OpenCode is sending telemetry to their own servers, even when you're using your own locally hosted models. There are no environment variables, flags, or other configuration options to disable this behavior.¹

At least you can easily turn off telemetry in Claude Code - just set CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC to 1.

You can use Claude Code with llama.cpp and vLLM, too right out of the box with no additional software necessary, just point ANTHROPIC_BASE_URL at your inference server of choice, with any value in ANTHROPIC_API_KEY.

Some people think that Anthropic could disable this at any time, but that's not really true - you can disable automatic updates and back up and reuse native Claude Code binaries, ensuring Anthropic cannot change your existing local Claude Code binary's behavior.

With that said, I like the idea of an open source TUI agent that won't spy on me without my consent and no way to disable it much better than a closed source TUI agent that I can effectively neuter telemetry on, but sadly, OpenCode is not the former. It's just another piece of VC-funded spyware that's destined for enshittification.
