You can try out a bunch of models on OpenRouter and see what works for you. Paying per token might be too expensive long term, but definitely a good way to figure out which models you like, and then look at providers.

The other big ones would be OpenAI with Codex and Google with their Gemini and their CLI or Antigravity. Or various IDE plugins or something like OpenCode on the tooling side. GitHub Copilot is pretty cheap and gives you basically unlimited autocomplete and generous monthly quotas that let you try out the most popular models. Also GLM 5.1 is pretty decent if you want to look at other subscriptions. Cerebras Code gave you a lot of tokens but their service wasn’t super stable last I tried and they also don’t give you the latest models.

Personally I just stick with Claude and the 100 USD Max subscription cause it still works really well, even the latest update today to the desktop app made it better (was slow and buggy a month ago, has been gradually getting better) and the Chrome plugin lets me get fully autonomous loops working.
