Claude Code
Handles larger multi-file tasks well, but it needs a paid Claude plan or API usage and plan usage limits apply.

Best AI coding tools
AI pair programmers and coding agents. Some autocomplete as you type; others read your whole codebase and make changes across files. Always review what they write.
Codex
Easy to try since it comes with ChatGPT, including the free plan, but the free tier is meant for quick tasks and serious use needs a paid plan.
FreemiumBest for chatGPT users who want a coding agent without a separate subscription
Cursor
A capable agent-centric editor, but since joining SpaceX its cheapest paid plan is limited to Grok models, so check plan details if you want other models.
FreemiumBest for developers who want an AI-first editor with agents built in
GitHub Copilot
The easiest pick if your code lives on GitHub, but the free plan limits chat and agent use, and heavy agent work burns through credits.
FreemiumBest for developers already working in GitHub and mainstream IDEs
Recursive Flint
A strong option for private, offline coding, but the full weights are about 80 GB and you have to set up and run the model yourself.
FreeBest for developers who want a capable coding model that runs locally and keeps code off third-party servers
Replit
The fastest route from idea to live app with no setup, but the free plan publishes only one project and the Agent can make mistakes you must catch.
FreemiumBest for non-developers and makers building working prototypes fast
Theorem OSS Verify
Offers a stronger guarantee than fuzzing alone at no cost, but projects must be accepted, builds must target static riscv64, and proofs can take days.
FreeBest for maintainers of widely used open source libraries that sit on a security boundary
