Here are the most exciting changes from the last month.

⚡TCP Checks Generally Available

We’re excited to announce that TCP checks are now available in Checkly across all plan types! After a successful beta phase, we’ve expanded functionality, improved documentation, and refined features to make TCP checks a reliable tool for monitoring your infrastructure.

Some use cases include:

• Mail servers – Ensure IMAPS or SMTP connections are available.

• Custom TCP services – Verify internal or external TCP-based applications.

• Firewalls – Confirm that specific ports are open or intentionally blocked.

Check out the TCP checks documentation to get started and learn more about usage, reporting and billing. TCP checks are fully integrated into Checkly’s Monitoring as Code (MaC) workflows and available in the CLI starting v4.19.1.

Pulumi Provider Update

The Checkly Pulumi provider has gotten a very much overdue update, including checkly test and checkly trigger retries, especially useful for CI workflows.

If you have any issues or feature requests, please report them in the checkly/pulumi-checkly repo directly!

Checkly CLI 5.0.1

Checkly CLI 5.0.1 is here!

• Requires Node.js 17 or a later version.

• Added support for alert channel constructs to define Incident.io, Microsoft Teams and Telegram alerts as code!

• Fixed the command line reporters to include the degraded status.

  

UX Improvements

Search for users by name or email in the members list

Reviewing and editing your team’s access to Checkly just got easier with search. Head over to members to check it out.

We’ve made further UX improvements based on your input:

• Date pickers now support time (hh:mm:ss) selection alongside the date. Making specific timeframes shareable as well.

• 6 decimal digits precision is now available on hover over the availability metric on the check results page.

• Individual check results are now clickable in Checkly dashboards, providing quick access to each check’s run details.

• The test sessions page has a new search box to help you find the one you’re looking for faster.

Private Location metrics

The endpoint private-locations/{id}/ metric now receives updates once a minute. The Prometheus export also gets updates every minute now.

Got feedback? We’d love to hear from you!

You can share your feedback on our feedback hub or connect via the Checkly community Slack.

Happy monitoring!

P.S. Thanks for reading this far! As a gift, we’d like to invite you to our private alpha for Playwright Native checks, where you can use Projects StorageState , @tags, custom dependencies, and all playwright features 🎭 — if you’re interested, reach out, and we’ll get you on the list!
