The Claude models are among the most expensive. It's easy to spend 30 EUR+ a day when providing it with a lot of context, documentation. Ofc it can be argued that this money is worth it relative to salaries, but recently I've switched to kilocode myself after looking at different model pricings on openrouter https://openrouter.ai/models?order=pricing-high-to-low There's just no reason to throw money away.
There are plenty of free (and also cheap ones) models you can use with just openrouter or kilocode (inexpensive less-shitty Cursor basically, https://kilocode.ai).
With most things these free models are able to achieve great results and similarly to the expensive ones they need oversight and thorough code reviews. These days I'm barely paying anything for tokens monthly.
