Use case
A free AI refactoring tool that runs your tests
Refactoring is where AI either shines or scares you — it touches many files at once. FreeCoder is a free AI refactoring tool that plans the change first, edits across the codebase, and runs your tests to prove behavior is unchanged.
Plan before you touch code
For big refactors, plan mode lays out every file and step so you approve the approach before anything changes. Then subagents can parallelize the work.
Safe by verification
FreeCoder runs your suite after refactoring and fixes regressions it finds — the safety net a refactor needs. Free to iterate until it's clean.
Get started free
You're one command away. On Windows, paste this into PowerShell:
irm https://freecoder.space/install.ps1 | iexThen run freecoder and open your project. Full steps in the getting-started guide.
A refactor you can trust is one that's tested. FreeCoder refactors and verifies, free.
