How does one manage monitoring in the age of digital infrastructure as code? Also as code, of course! Combining HashiCorp Terraform Cloud and Checkly enables you to configure synthetic and API monitoring as part of your existing infrastructure codebase. It is flexible, programmable and will keep you out of maintenance hell, even at scale: it is monitoring for developers. Extending your existing Terraform Cloud configuration takes only two minutes. Let's take a look together.

When we decided to build Checkly's browser checks, we chose to do so with Puppeteer, an open-source headless browser automation tool, later adding Playwright, too. We wanted to support users with synthetic monitoring and testing to let them know whether their websites worked as expected at any given moment. Speed was a primary concern in our case. Yet, determining which automation tool is generally faster is far from simple.

We recently optimized the hell out of our Lighthouse score, and one of our landing pages went from a low 70s score to a cool 96 and above score. Below I describe what started as a quick lunch break peek into the Google Search Console. I recognized that our 'Pingdom alternative' landing page ranks surprisingly well with nearly no investment. BUT the competition was ranking even better. So, why? Common knowledge is that Google-Search is using hundreds of ranking factors.

Managing large numbers of checks by hand quickly becomes cumbersome. Luckily, Checkly's REST API allows us to automate most of the repetitive steps. Building on that API, the Checkly Terraform Provider takes automation one step further, enabling users to specify their active monitoring setup as code. In this article, we will be building on top of John Arundel's great intro from a few months back and showing how to manage multiple checks using groups and shared code snippets.

We are really excited to announce that you can now use Playwright in your browser checks. If you didn't know yet, Playwright is Microsoft's headless browser library. It's very similar to Puppeteer. In fact, it was built by the original creators of Puppeteer and has mostly the same features and a remarkably similar API. This was in our public roadmap and cooking for some time now and we're glad to have it out the door!

After weeks of writing, researching and hopefully enough proofreading, we just launched a living collection of practical guides on leveraging headless browser tools (starting with Puppeteer and Playwright) for testing, monitoring, scraping, performance measuring and more. We called it theheadless.dev. This article is about the different approaches we tried in contributing ideas to the Puppeteer community, as well as the principles that guide our latest contribution.

We just updated our SSL certificate expiration alerting. This update gives you more control over where and when you want to receive these alerts. Before today, certificate alerts were set as part of "Alert Settings" tab, either globally or using specific settings for checks & check groups. This wasn't all that flexible and more granular control was already on our public roadmap.

If you follow our very own @HLENKE, you might have seen his recent tweet. Availability and responsiveness are key topics for every SaaS platform. They also happen to be multi-level, complex topics that often span different technology stacks and can be tackled with a variety of approaches. Hannes' tweet actually gives us the perfect segue into a blog post about how our engineering team currently monitors Checkly.

Exciting times ahead. With the Jamstack gaining momentum, the landscape around it is offering more and more tools to streamline developer workflows and free up time for actual development. A cutting edge solution in this interesting space is Vercel, formerly known as ZEIT. In this blog post we will get a taste of Vercel's capabilities by using it to deploy and preview a sample Gatsby blog - and while we're at it, we will of course take the chance to kick off some checks automatically from Checkly.

Use Puppeteer Recorder to fill out forms with inputs, drop downs, radio buttons, check boxes etc.

Puppeteer recorder is a Chrome extension that records your browser interactions and generates a Puppeteer script.

Downtime caused by API performance has serious business impact. Use Checkly's deep but easy to use API monitoring solution to check your mobile, webapp or IoT API for performance, uptime and correctness.

Checkly is the easiest way to monitor your API's and Browser click flows from a single dashboard. Use a powerful assertions engine to check all your (mobile) API's for timeliness and correctness. Use javascript to check your most crucial browser transactions. Built specifically for developers and ops teams.

We run your checks from multiple global data centers and alert you when things go south with SMS, Pagerduty etc. Add team mates, call checks from your CI/CD pipeline and publish a status page under a custom domain. We also do SSL expiry checks!

Features at a glance:

  • No more broken APIs: Make sure your API is always responds quickly and with the correct payload. Get started quickly with our Swagger or cURL importer and super easy API monitor creator.
  • No more broken shopping carts: Monitor and validate your most crucial site transactions like logins, shopping carts and onboarding flows. Take screenshots to get instant insights into what's working and what's not.
  • Alerting without limits: Keep your team up to date with a generous helping of SMS messages and unlimited email, Pagerduty, Slack and web hook notifications. Control exactly how, when and how often you get alerted. Of course, "double-checking" is enabled by default to never get false positives.
  • Insights without limits: Doing a root cause without complete and accurate data is insane. But too much detail can also be distracting. That's why next to calculating aggregates to keep an overview, Checkly stores each and every raw result for you and your team to dive into.

A better way to monitor your APIs and site click flows.
