Claude Code
Anthropic's AI coding agent: it works through a whole task in your codebase, running commands and editing files as it goes.
Autocomplete finishes your line. Claude Code takes the whole task. It reads the repo, plans the change, edits the files and runs the tests, and it asks before doing anything risky.
My opinion changelog here is slightly embarrassing. I thought GPT was mostly hype. Then I used only Claude Code. Then I decided Codex was better. Now I pay for both. Make of that what you will.
What matters more than which agent you pick is the context file. A CLAUDE.md (or AGENTS.md, which Codex reads) that says how to run and test the project makes any agent far less confused.
For Base44 work, install Base44's official skills first. Then it writes entities and access rules the way the platform expects, instead of the way some random tutorial did.
