Tandem Browser and Browser Use both let AI agents operate web pages. They look adjacent from a distance but solve genuinely different problems. Browser Use is a Python library for scripted, headless automation. Tandem Browser is a desktop browser where the agent works in your real session, alongside you. This page is for picking the right tool for your situation.
| Tandem Browser | Browser Use | |
|---|---|---|
| Distribution | Desktop browser app | Python library |
| Mode | Headed (visible browser) | Typically headless |
| Who runs the session | You and the agent share one session | Agent runs its own session |
| Integration | MCP or HTTP from any language | Python only |
| Human-in-the-loop | Yes — agent can ask you, you can interrupt | No — designed for unattended runs |
| Authentication | Uses your existing logged-in session | You handle auth in script |
| Works offline | Yes (with local model) | Depends on model setup |
| License | MIT (open source) | MIT (open source) |
| Maturity | Development preview | Mature, widely used |
| Best for | Co-browsing with AI | Headless automation pipelines |
Both Tandem Browser and Browser Use are open-source, both let AI agents act on the real web instead of through brittle wrappers, and both bet that real-browser interaction is more honest than synthetic APIs. They serve different points on the same spectrum.
