What BrowserOS is

BrowserOS is an open-source browser that runs AI agents locally: give instructions in natural language and agents click, type and navigate on your behalf, with model sidebars and support for your own API keys or local models.

What you can do with it

Automate form filling and routine navigation
Discuss and summarise pages in the sidebar
Route tasks through local models
Keep browsing data on your machine
Audit the code yourself

Who it is for

Privacy-minded automation users
Developers comfortable with open source
Teams avoiding cloud browser tools

What to watch out for

Agents acting on pages can misfire; supervise actions on accounts that matter
Site terms still apply to automated behaviour, even local automation
Local model quality depends on your hardware
Bring-your-own-key means your API spend is yours to monitor

Pros & cons

✓ What we like

FAQ

Does my data leave the machine?

With local models, no; with cloud models or keys, requests go to those providers.

Can it fill logins automatically?

Avoid credential and 2FA automation; keep authentication manual.

Is it production ready?

Open-source browsers at this stage vary; test your critical workflows.
