In their own words
Tandem Browser
Tandem Browser is a free, MIT-licensed browser in developer preview for running AI agents alongside a person’s browsing session. Agents share tabs, cookies, and the DOM, and can work with the accessibility tree, rendered DOM, network requests, console output, and DevTools. If an agent reaches a CAPTCHA, unclear form, or judgment call, it pauses for user help. MCP- or HTTP-speaking agents can connect locally or through a private Tailscale network, with separate workspaces and tab locks. The documented API includes more than 280 HTTP endpoints and 257 MCP tools, protected by bearer tokens. Tandem has no cloud backend, subscription, or telemetry according to its FAQ; browsing data remains on the machine unless sent elsewhere. It can run offline with Ollama or LM Studio. Daily-driver features include extensions, bookmarks, history, a local password vault, workspaces, and sidebar apps. It uses Chromium and supports macOS Apple Silicon, Windows 11 x64, and Linux on a best-effort basis.
