Agent Browser hero - isolated browser sessions for AI agents
WHY AGENT BROWSER

Built for agents, not for scraping.

WHAT'S INSIDE

Nine actions. One API. Hard boundaries.

Every action is a single API call. Every egress request is checked against your allowlist.

  • Hardened container

    Non-root user, read-only rootfs, dropped Linux capabilities, RuntimeDefault seccomp profile.

  • Egress allowlist

    Set the domains each session can reach. Anything outside the list is refused at the proxy.

  • Accessibility tree

    Agents see a structured tree of roles, names, and values. No raw HTML, no raw CDP.

  • Session-scoped refs

    Element references expire with the session. No persistent IDs to leak across runs.

  • Closed action set

    navigate, observe, click, fill, select, press, scroll, wait_for, screenshot. Nothing else.

  • One integration

    One Telnyx API key covers Agent Browser, Web Search, and Inference.

GET STARTED

Three calls to a working session.

Create a session, navigate to a page, observe the result. The full API surface fits in a few hundred lines.

FAQ

Agent Browser is a developer preview API that gives AI agents controlled access to a real browser. Each session runs in an isolated Kubernetes pod with a fail-closed egress proxy that enforces a per-session domain allowlist.
