Agent journey checks for every release

GhostOwl gives engineering teams agent journey checks they can run from an editor through MCP, and on preview URLs before a release ships. Every failed run comes with a replay, the agent’s message and a Playwright repro.

Why engineers wire it in

  • Agents break quietly

    A new modal or a bot rule change can stop agents without any error in your logs.

  • Marketing finds out late

    Checks on previews catch it before a growth lead forwards you a replay.

  • Repros save the back-and-forth

    Every failed journey exports as a runnable Playwright script.

What the Developer plan includes

  • MCP server

    Run scans and read reports from Claude Code, Cursor and other MCP clients.

  • CI on preview URLs

    Run journeys against Vercel, Netlify or Cloudflare previews. Advisory by default.

  • Playwright repro export

    Every failure comes with a script you can run locally.

  • API

    Start scans and pull scores and reports into your own tools.
  • The Developer plan is $29 a month per repo, and included free in Monitor.
  • Every request carries the GhostOwl user agent and a Signature-Agent header.

Getting started

  1. Add the MCP server

    Point your MCP client at ghostowl.ai/mcp and sign in.

  2. Run a journey

    Ask your assistant to scan a URL and read back where agents failed.

  3. Gate your previews

    Add the CI check so journeys run on every preview deploy.

Questions

Which agents does GhostOwl run?

Three different agents run every journey: Stagehand, Browser Use and a frontier computer-use model. Each one gets three attempts, and one always runs as a cold-start cloud browser with no cookies, logins or history. The fidelity panel in every report names each agent and model version used.

How do I allowlist or block GhostOwl?

Every request carries the GhostOwl user agent and a Signature-Agent header pointing at ghostowl.ai, so you can allowlist it in Cloudflare or your bot tool, or exclude it from analytics. To stop scans of your domain, email support@ghostowl.ai.

Can I run GhostOwl from my editor or CI?

Yes. The GhostOwl MCP server lets Claude Code, Cursor and other MCP clients run scans and read reports, and CI checks run journeys against preview URLs before you ship. Both come with the Developer plan, which is included in Monitor.
