OHarness - Your AI Workspace, Free from Model Lock-in

Lets the OHarness agent on your computer, running any model you choose, work in the Chrome you're already signed into.

OHarness Browser Bridge lets the OHarness Desktop running on your computer use the Chrome you are already signed into, so it can work on sites that need your login without a second browser or signing in again. HOW IT WORKS • The extension talks only to the OHarness app on this computer, through Chrome's native messaging. It has no server of its own and sends nothing over the network. • It forwards Chrome DevTools Protocol messages between OHarness and the tabs OHarness controls. Every decision about what to do on a page is made by OHarness on your machine. • Each OHarness conversation opens its own tabs, in a tab group named after the conversation. Tabs you opened yourself are used only when a conversation is told to use one. • Several conversations, from the desktop app, the web UI or the terminal, can share one browser at the same time. ALWAYS VISIBLE, EASY TO STOP • While any tab is being controlled, Chrome shows its own "started debugging this browser" banner. The extension does not hide it. • The toolbar badge shows how many tabs are being controlled. • The popup lists every controlled tab, grouped by conversation. "Stop controlling all tabs" hands them all back at once. Cancelling Chrome's banner, or disabling the extension, does the same. REQUIREMENTS The extension does nothing on its own. It needs OHarness (https://oharness.ai) on the same computer: • The OHarness desktop app sets everything up when it starts, or • With the npm package, run: oharness-browser-host install Then turn on "Use your own browser" in OHarness settings. OHarness is free to use with your own model provider key; an optional subscription is available at https://oharness.ai/pricing.
