ANTHROPIC JUST ACCIDENTALLY LEAKED THE ENTIRE CLAUDE CODE SOURCE (512,000 LINES) — And the Community Turned It Into Pure FIRE
Anthropic’s team shipped an npm update… and forgot to delete the debug source maps (.map files). Boom — the full TypeScript source code for Claude Code spilled out into the open.
What happened next is straight-up legendary.A Korean developer (
@realsigridjin— the guy who burned 25 billion tokens last year) rewrote the whole thing overnight into claw-code (clean Python version).
The team is now rebuilding v2 in Rust… and the code is already permanently on IPFS. Anthropic can’t delete it even if they wanted to.
Another dev (
@paoloanzn) recompiled it into free-code — the unrestricted, fully unlocked version.
This is the biggest open-source AI gift of 2026 Here’s exactly what you can grab right now:
1. claw-code (Python rewrite)
→ Local, clean Agent harness. Run Claude Code-style tools 100% offline. Perfect for studying architecture and building fast.
github.com/instructkr/claw-c…
2. free-code (The unrestricted build)
→ All telemetry & enterprise guardrails deleted. Every single hidden/experimental feature turned ON
github.com/paoloanzn/free-co…
3. Full Hidden & Unreleased Features Bible
→ Complete list of everything Anthropic never publicly showed: 8 unreleased features (Buddy AI pet, KAIROS, Ultraplan, Coordinator Mode, etc.), 26 secret slash commands, 32 build flags, 120 secret env vars.
