Tandem Browser review
A free Chromium browser for teams sharing human-and-agent sessions, with deep inspection tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Tandem Browser is an open-source desktop browser that lets AI agents work inside a person’s real browser session. It is aimed at teams that want agents to navigate websites and automate SaaS workflows without separate site APIs, while keeping people in the loop for judgment calls. Shared tabs, cookies, and authentication let human and agent work happen in the same session; the browser’s local privacy model also suits teams that prefer browser activity to remain local.
Its standout strength is how much browser context and control agents can access. Page interaction can use the accessibility tree or DOM, and the feature set includes navigation, clicking, typing, scrolling, form filling, live network inspection, and DevTools access. Agents can also rewrite live interfaces through injected userscripts. Workspaces and tab locks support multiple agents, while human handoffs cover CAPTCHAs, risky actions, and ambiguous tasks. This depth fits developers and teams building browser-agent workflows; people looking for a conventional browser with only lightweight AI assistance may find the focus too specialized.
Tandem is presented as a free developer preview, not as a set of paid plans. Connectivity includes MCP and an HTTP API, with support for Claude, GPT, Gemini, OpenClaw, Ollama, and LM Studio; remote agents can connect over private Tailscale networks. The published platform details specify macOS Apple Silicon and Windows 11 x64, with Linux support best-effort, and identify Chromium as the browser engine. Choose Tandem for shared agent sessions, inspection, and automation across web apps. Teams requiring stronger Linux support or a browser engine other than Chromium should consider an alternative.
