See it in action

AI should read your code,
not your secrets.

LocalMask scans your repo, masks every secret, organizational data, and PII into safe tokens, and lets you share code with AI — without leaking passwords, internal hostnames, or company details.

Local-first privacy for AI coding

AI should read your code,
not your secrets.

LocalMask runs entirely on your machine. It scans your repo, masks every credential, key, piece of PII, and organizational data into reversible tokens, then sends only safe tokens to Claude, GPT, or Gemini. Answers come back and get rehydrated locally — you stay in full control, and the real secrets never leave your local environment.

No spam — one note when the private beta opens.

You're on the list. We'll reach out when the beta opens.

Free CLI · open source

Install and mask a repo in two commands.

Download the free CLI (.tar.gz)
tar -xzf localmask-free-0.9.0.tar.gz && pip install ./localmask-free-0.9.0
localmask scan ./your-repo

Then localmask publish <scan> <masked-repo-url> creates a private masked git mirror your AI tools can safely read. Once we're on PyPI you'll also be able to pip install localmask. Full guide on GitHub →
