Updates

  • Checkly now has AI wired into every stage of the monitoring lifecycle: agents that write checks, Rocky AI for root cause analysis, and incident resolution from the terminal. On the 28, Stefan Judis will connect all AI capabilities into a single live workflow, from generating checks with a coding agent to closing an incident without ever opening a dashboard.

  • Control who sees your status pages! 🔒 Checkly status pages now support password protection, so you can share service health with the right audience without exposing it publicly. Use it for internal teams, partners, or select customers. Turn it on, share the password, and keep access limited to the people who need it. No SSO setup required.

    50% of Checkly CLI users today are already coding agents. Claude, Cursor, Codex and friends will be the new power users of developer tools using CLIs. At Checkly, we ship a new CLI release every week to make it work better for agent workflows. Here's what we've learned about making a CLI agent-ready:  1. Built-in documentation Don't let agents rely on training data. That's where hallucinations start. We embedded docs directly into the CLI via a new `npx checkly skills` command. There's no docs fetching or guesswork. The CLI is the product and(!) the docs.  2. Progressive disclosure  Agents don't need your entire docs dumped into context. `npx checkly skills` is granular so agents pull only what they need, when they need it. This approach keeps token usage low.  3. Agent detection  The CLI detects whether a human or an agent is using it. Humans get interactive dialogues. Agents get non-interactive flags and structured guidance. It's a small change that makes a big difference. Agents are terrible at "Press Y to continue" prompts. 😅  4. Guardrails  When an agent tries to open an incident or deploy monitoring changes, the CLI rejects the call and says: "Ask a human first." Your agent shouldn't be able  to notify all your customers at 2am without someone signing off.  5. Structured output  JSON, markdown, filtered views — agents need machine-readable output to reason about your monitoring state. "Which checks are failing?" shouldn't require parsing ASCII tables. I did a full walkthrough of all of these CLI features in a webinar this week. Claude set up monitoring from scratch and handled a production incident for me. If you're curious to see it in action, check it out. And you know the drill, the link is in the comments.

  • 50% of Checkly CLI users are already coding agents. In our latest session, Stefan Judis showed what that means in practice. He ran two live demos: first, setting up a full monitoring suite (Playwright checks, URL monitors, API checks) in a single agent conversation. Then, triggering a real production failure and letting the agent detect it, trace the root cause in git, open an incident, deploy the fix, and resolve it. All through the CLI. Link in comments.

    Synthetic monitoring in production is hard, especially on Shopify. Cookie banners, bot protection, and checkout flows can all get in the way of testing what matters most. We’ve just published a guest post from Vince Graics at World of Books on how his team made Shopify monitoring work in practice using Playwright and Checkly. Thanks to Vince Graics for collaborating with us on this one! Read the full article here: https://lnkd.in/dFyg653M #Playwright #Shopify #SyntheticMonitoring #MonitoringAsCode

  • "Why would you run Playwright against production?" Stefan's answer: "Why not?" In the session, he took the same test files running against localhost and deployed them as scheduled production monitors with two commands: npx checkly test — runs your Playwright suite from any global location npx checkly deploy — turns those tests into monitors that run every 10 minutes Same code. No rewrites. If your login breaks in production at 3 AM, you know before your users do. Link in comments.

  • Stefan ran a live demo of Claude with Playwright MCP during the session. One sentence prompt: "Navigate to the site, click the first product, add it to cart." The agent browsed the page using the accessibility tree, wrote a test file, ran it, and when it failed, it fixed its own locators and re-ran until it passed. Impressive, but Stefan's takeaway was clear: AI scaffolds tests fast, but you still need to review what it writes before it goes into your suite. The full demo is in the recording. Link in comments.
