Comparison with other tools
How oh-my-webbridge differs from other tools that give an agent a browser, and which tasks another tool covers better.
Developer preview
omw is in developer preview and iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
This page compares oh-my-webbridge 0.2.0 with other tools that give an agent a browser. The facts come from the documentation, release pages and source code of each project, read on 12 November 2026 for the versions in the first table. "Not documented" means that the documentation of the project does not say. To report an error or a newer release, open a GitHub issue. To move an existing setup, see Migrate to oh-my-webbridge.

Access to a signed-in browser
A tool reaches the browser you use in one of two ways. An extension drives tabs through browser APIs and needs no browser flag. Remote debugging gives the client the whole browser. Chrome 144 and later turn it on for the running browser from chrome://inspect/#remote-debugging and ask you to allow the connection. The --remote-debugging-port switch requires a profile directory other than the default one (remote debugging changes).
| Tool | Mechanism | Setup | What the agent can reach |
|---|---|---|---|
| oh-my-webbridge | Extension: chrome.debugger in Chrome, WebExtension APIs in Firefox | Install the extension and enter the code from omw pair once | Tabs that its sessions open, and the active tab that find_tab borrows |
| Kimi browser extension | Extension with chrome.debugger | Install the daemon and the extension | Tabs that its sessions open, and the active tab that find_tab borrows |
| Browser MCP | Extension with chrome.debugger, attached only to tabs that an agent uses | Install the extension and the MCP server, compare a six-digit code once and allow it | Tabs that the agent opens, your tabs that it selects with tab select, and tabs that you drag into its tab group |
Playwright MCP with --extension | Extension relay | Approve each connection on the connect page, or set PLAYWRIGHT_MCP_EXTENSION_TOKEN | Tabs in the tab group of the MCP client |
| Playwriter | Extension relay | Click the extension icon on each tab to control | Every tab with the extension turned on, from every session |
| OpenCLI | Extension with the debugger permission | Install the extension | Tabs in its own tab groups, and tabs that a session binds |
| Claude in Chrome | Extension with the debugger permission | Install the extension and sign in with a paid Claude plan | Tabs in the tab group of the conversation, and tabs that you add to it |
| Chrome DevTools MCP | Remote debugging: --autoConnect (Chrome 144+), --browserUrl or --wsEndpoint | Turn on remote debugging and allow the connection | Every window of the profile |
| agent-browser | Remote debugging: --auto-connect or --cdp | Turn on remote debugging and allow the connection | The whole browser; --pin-tab binds a session to one tab |
| PinchTab | Remote debugging through POST /instances/attach, off by default | Turn on attach in the configuration and start Chrome with remote debugging | The whole browser |
| browser-use | Remote debugging | Turn on remote debugging at chrome://inspect/#remote-debugging | The whole browser |
Tasks, visibility and local access
| Tool | Unit of a task | Visible marks | Local access control |
|---|---|---|---|
| oh-my-webbridge | Named session with its own tabs and tab group, in the shared profile | Session chip, agent pointer and focus frame on the page; amber pointer on the toolbar icon | Bearer token that omw connection prints; the extension gets it by pairing. Requests with a web Origin or another Host are rejected |
| Kimi browser extension | Named session with its own tab group, in the shared profile | Not documented | The requests in its agent guide carry no credentials |
| Browser MCP | One tab group for each AI application | Chrome's debugging bar; tab count on the toolbar icon | Token in ~/.browsermcp/daemon.json; signed pairing with the extension |
| Playwright MCP | One tab group for each MCP client | Tab group named after the client; a status page lists the connected clients | Approval on the connect page, or the extension token |
| Playwriter | Numbered session that keeps its own variables; all sessions share the tabs | Chrome's automation bar; green extension icon | Origin check for the extension; a token for remote access only |
| OpenCLI | --session name that holds a tab lease | Not documented | Its documentation states that it uses no tokens |
| Claude in Chrome | Tab group for each Claude Code session | Works in the visible window and pauses for logins and CAPTCHAs | claude.ai sign-in in the extension and in Claude Code |
| Chrome DevTools MCP | One server for each conversation; isolatedContext separates cookies | Not documented | Chrome's remote debugging approval |
| agent-browser | Session with its own daemon, browser and cookies | Not documented | A socket for each session; its settings file must be readable by the owner only |
| PinchTab | Instance: one Chrome process with one profile | Not documented | Bearer token |
Capabilities of the closest tools
"Yes" and "No" refer to the commands or tools that each project documents. A capability that a tool reaches only through arbitrary code counts as "No".

When another tool fits better
- The agent calls tools only through MCP. Playwright MCP, Browser MCP, Chrome DevTools MCP, agent-browser, PinchTab and Playwriter run as MCP servers. oh-my-webbridge has no MCP server; an agent runs
omw callas its skill describes. - Windows. The Kimi browser extension, Playwright MCP, Chrome DevTools MCP, agent-browser, Claude in Chrome and the OpenCLI desktop app support Windows. Playwriter supports WSL, and PinchTab publishes Windows binaries with limited support. oh-my-webbridge runs on macOS and Linux.
- Microsoft Edge. The Kimi browser extension, Browser MCP and Playwright MCP with
--extensionwork in Edge. oh-my-webbridge supports Chrome and Firefox. - Installation from an extension store. The extensions of Kimi, Browser MCP, Playwright MCP, OpenCLI and Claude in Chrome install from the Chrome Web Store and update automatically. The oh-my-webbridge extension loads as an unpacked folder in Chrome, and Firefox keeps it after a restart only when it is signed.
- Several browser profiles at once. One Browser MCP daemon connects up to 8 browsers or Chrome profiles. The oh-my-webbridge daemon accepts one Chrome connection and one Firefox connection.
- A separate cookie store for each task. agent-browser sessions, PinchTab profiles,
--isolatedandisolatedContextin Playwright MCP, andisolatedContextin Chrome DevTools MCP keep cookies apart. All sessions of oh-my-webbridge share the browser profile. - No desktop browser, for example in CI. agent-browser, Playwright MCP, Chrome DevTools MCP and PinchTab start their own browser, headless when needed. oh-my-webbridge needs a running Chrome or Firefox with its extension.
- Performance, memory and network debugging. Chrome DevTools MCP records performance traces, runs Lighthouse and reads heap snapshots. Playwright MCP, Chrome DevTools MCP and agent-browser mock network responses.
- The full Playwright API on your signed-in tabs. Playwriter runs Playwright code on the tabs on which you turn its extension on.
- Ready-made commands for popular sites. OpenCLI ships adapters that return structured data from more than 100 sites.
- A model in the tool. Claude in Chrome and the Kimi side panel run a task with their own model. browser-use runs a task with a model that you configure, and Stagehand adds AI steps (
act,observe,extract) to a script. oh-my-webbridge carries out the commands of the agent you use and contains no model.
