Agent Browser is a Rust command-line tool from Vercel Labs that hands a coding agent direct control of a browser, designed to slot into an existing agent setup rather than replace it. It runs locally and uses whichever model and credential your agent is already configured with, so it adds browser capability without adding a party to the request path. Apache-2.0.

How this tool was scored

Key handling 77/100 (where your key rests and who sees it, comparable across any licence) and verifiability 70/100 (how much of that BYOAIK could confirm, lower for closed source). Neither contains a popularity signal.

  • Key Safety 22/25: The key is supplied by an environment variable or local config file you control.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under Apache-2.0, so anyone can check how the key is handled.
  • Privacy 7/15: Nothing specific is known about its data handling beyond the key itself.
  • Maintenance 10/10: Actively developed, with commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

How your API key is handled

Your API key is supplied via an environment variable or local config file. Requests are sent directly to the AI provider.

Setup

Install the tool, set your provider API key as an environment variable (or in its config file), and pick a model.
