veil is an agent framework - Local privacy proxy for AI coding agents. Keep PII and secrets out of LLMs with deterministic pseudonymization.

OverviewLink to this section

Your AI coding agent reads production-shaped data. veil makes sure the model never sees a real person.

veil is a local privacy proxy for AI coding agents such as Claude Code, Codex CLI, Aider and DeepSeek Harness. It replaces every real name, email, phone number, address, ID number and secret with a consistent pseudonym before the request leaves your machine. When the agent runs a command, queries a database or edits a file locally, veil swaps the real values back in, safely escaped. The model reasons about real bugs; it just never learns who they happened to.

The model still found the bug (invoice 293 was charged twice within the same second). Its answer came back to the developer with the real name, card number and address restored. The provider saw none of them.

veil is published on PyPI as 'veil-proxy'. It installs the 'veil' and 'veil-hook' commands, on macOS, Linux and Windows.

Keys are kept in the OS keychain: macOS Keychain, Linux Secret Service, or Windows Credential Manager. CI or containers can use 'VEIL_VAULT_KEY' / 'VEIL_TOKEN_SECRET' instead.

veil is open-source, written primarily in Python, with 195 GitHub stars under the Apache 2.0 license. It was last updated on 2026-10-31.

From the project's documentation:

• Finds the project's data:
• database URLs in .env files (DATABASE_URL, REDIS_URL, MONGODB_URI, …);
• SQLite files and fixture folders;
• the git history (contributors);
• personal fields declared in code (Prisma, Django, Rails, SQLAlchemy, OpenAPI, protobuf).
• Seeds veil with the real values, and remembers the sources (encrypted) so it re-seeds them when

A quick way to get started (always check the official docs for the latest):

pip install veil-proxy # core: httpx, cryptography, pyahocorasick

How it fits a local-AI stackLink to this section

veil runs on your own hardware, so pair it with a model and a GPU sized to your needs. Use the VRAM calculator to pick a model that fits your card, and see what you can run for hardware guidance. Related agent frameworks in the directory:
