Does this conversation exist in 2026? If we can all code everything quickly and SaaS has no value then just build your own in a weekend and put GitHub out of business?

There is a fundamental contradiction here.

Github is an ecosystem and its biggest moat is the number of people that use it.

To make a replacement, not only do you have to improve on support for every major use case at a technical level (no easy task, to put it mildly), you also have to make it so compelling to use that Github users will abandon Github en masse.

Someone with an LLM assisted IDE has the theoretical potential to improve on all major Github features. But to make their replacement compelling enough to get folks to leave Github? Not a chance.

No one wants to do it-- but it's foundational.

It's also very hard to appease everybody; from visual design to operational smoothness.

If you can code it up quickly please do so. I'll sign up. I'm already busy coding other things.
