Shorter, clearer code, checked against the original.

Your agent refactors for fewer lines and less complexity. The goatedcode engine fuzz-tests every refactor against the original, so the code gets easier to read without changing what it does.

How it works

The same steps every time, inside VS Code or Cursor.

Pick the code

Open the simplercode panel on a function you no longer enjoy reading.

Your agent simplifies it

Claude Code or Codex writes simpler versions in its own workspace.

The engine proves nothing changed

Each version is fuzz-tested against the original before you see it.

What you get

Lines or complexity

Choose what to reduce. The winner is the simplest version that passed every check.

Safe by default

A refactor that changes any result, side effect or test is rejected, never applied.

Dead code, too

Code nothing calls any more is found and removed with the same checks.

Powered by the goatedcode engine

simplercode is one of the goatedcode tools, all built on the same engine. It checks every change against the original: real inputs, generated edge cases, side effects, your own tests and planted bugs. How the engine works →
