Local-first
Run against a loopback API by default, with profile data on the workstation you control.
Private developer preview
Local browser profile infrastructure for Chromium automation.
Create persistent profiles, launch patched Chromium sessions, test proxies, and control everything through a local REST API and browser-based control panel.

Persistent profiles
Keep cookies, local storage, extension state, fingerprint configuration, and profile metadata together.
Exclusive locks
Protect each profile with one active launch session at a time, including multi-host coordination through Postgres.
API + UI
Automate through REST and CDP, or operate from a browser-based control panel.
Control plane
One workflow for developers and operators.
Build
A local API for browser profile workflows.
Create profiles, assign proxies, launch Chromium, collect a CDP endpoint, and stop sessions from the same predictable REST surface.
Operate
A control panel for repeated profile work.
List, edit, clone, import, export, launch, compare, and review profiles without leaving the local browser UI.
Scale carefully
Ready for single-host and multi-host setups.
Start with SQLite on one machine, then move coordination to Postgres when multiple hosts need shared profile locks.
