Agent Browser

Verifiedby Chris Tate (@ctatedev) / Vercel LabsUpdated 3 months ago

“Browser automation CLI for AI agents by Vercel Labs. Uses snapshot refs instead of DOM selectors for 90% fewer tokens than Playwright MCP. Now supports Electron desktop apps — control Discord, Figma, Notion, Spotify, VS Code, and more. Daemon persists between commands for fast sequential operations. Includes optional Rust native binary for extra speed. Install: npm install -g agent-browser”— Chris Tate (@ctatedev) / Vercel Labs

Agent Browser - snapshot refs over DOM selectors is the right call. Less time fighting selectors, more time shipping.

Snapshot refs approach is clever - way fewer tokens than full DOM. Electron support for Discord and Notion is the surprising win here.

90% fewer tokens than Playwright MCP? Yes please. Electron app support is the cherry on top.

The snapshot refs approach is genuinely better than selector-based automation. Way fewer brittle tests. Electron support is a nice bonus.

npm install -g and you're automating browsers. Token-efficient snapshots keep API costs low, daemon persistence kills cold-start overhead.…

Just installed this and the snapshot output is incredibly clean. Interactive element refs (@e1, @e2) make clicking and filling forms trivia…
03SECURITYWHAT WE CHECKED
Not yet security-checkedThis tool has not been through the security scan yet. Absence of a result is not a verdict either way.
How to read this: these are static checks over the source at a point in time. They catch the patterns above, not everything. Absence of a flag is not absence of danger, and a tool that runs cleanly can still behave differently once installed. We do not call any tool simply "safe". Runtime-behavior checks are the next layer we are adding.
