Introduction

A Zig-built binary (~1.5 MB) for grabbing browser OAuth/OIDC tokens (localStorage), session and SSO cookies, and saved credentials (password manager).

Cross-platform support on Linux, macOS and Windows.

Works on both x86_64 and arm64 CPU architectures.

At current state, authgrabber reads from both Firefox-based (Firefox, Zen) and Chromium-based (Vivaldi, etc.) profiles.

Quick start

Export session for obscura

just release
mkdir -p ~/.config/authgrabber/session && chmod 700 ~/.config/authgrabber
./zig-out/bin/authgrabber export-session --format obscura --values --out ~/.config/authgrabber/session/cookies.json
obscura fetch <url> --storage-dir ~/.config/authgrabber/session --stealth \
  --user-agent "$(./zig-out/bin/authgrabber user-agent)"

See the CLI reference for all commands, and the browser internals for how the stores work under the hood.
