ITG NowAI for Developers, in plain words
Free AI tools for developers make AI coding helpers like Claude Code, Codex and Cursor plan better, test more and spend fewer tokens. Every tool below is free and open source.
What free AI tools do for developers
Make the AI plan and test. Superpowers has your AI ask what you want before it builds. It splits work into tasks of 2 to 5 minutes, writes tests first and reviews between tasks. Matt Pocock's skills start with /grill-me, where the AI interviews you about your plan before it writes a line. gstack adds 23 specialists and 8 power tools as slash commands, per the gstack README.
Spend fewer tokens. Tokens are the small chunks of text AI services charge by. Caveman keeps answers short, and its README reports 33.2% fewer input tokens across its test sessions. RTK trims long command results, like test runs, and works with 18 AI coding tools. Headroom shrinks logs and files on your computer before the AI reads them.
Find code faster. CodeGraph builds a local map of your project. In the makers' own tests, Claude Code used 88% fewer tool calls and cost 44% less on average, per the CodeGraph README. Understand Anything turns a codebase into a clickable map with guided tours.
Check security and drive a browser. Cloudflare's Security Audit skill makes your AI a security reviewer, with a fresh checker that tries to disprove every finding. Agent Browser from Vercel Labs lets your AI drive Chrome, with a list of allowed websites and an "ask me first" step for risky actions.
What's trending right now
Every week, month and quarter we rank the GitHub repos that gained the most stars and explain each one. See the top GitHub repos of September 2026 and the best repos of Q3 2026. The newest AI news about coding models and open-source releases shows up in the news list on this page.
Before you install
Most savings numbers above come from each tool's own makers, so test on your own project. Start with one add-on at a time, so you can tell what each one changes. These tools are free, but the AI helper you run them in may need a paid plan. For the tools picked for engineering teams, see AI for engineers.
