Loadster is a cloud-based load testing and synthetic monitoring platform for engineers who want to know how their applications behave under real traffic.

Tests run with three types of bots: Protocol Bots for HTTP testing, headless Browser Bots that render full pages and execute JavaScript in real Chrome browsers, and Playwright bots for when you want to use Playwright JS directly.

Loadster scripts can be recorded from Chrome or Firefox with the Loadster Recorder extension, edited in a built-in editor with variables, datasets, and shared includes, and then replayed from multiple cloud regions.

Each test run returns detailed page timings (TTFB, FCP, LCP, CLS, etc) alongside resource waterfalls, screenshots, and full traces you can step through in a self-hosted trace viewer. Tests scale from a handful of virtual users (bots) to hundreds of thousands across distributed cloud engines without you provisioning anything.

The same scripts can be set up as monitors that run on a schedule from chosen regions. Notification policies route incidents to email, SMS, voice, or integrations like Slack and PagerDuty. Projects, roles, and shared test history keep teams aligned on what passed, what failed, and what changed.

Pricing is usage-based via Loadster Fuel, with 50 free units on sign-up and no credit card to start.

  • Experimenting with Random() in CSS
    The point isn't showing what they look like, it's that the result is randomized. Screenshots aren't, so that kind of defeats the purpose. The article starts with instructions on how to actually see and interact with the demos (the easiest is to use [Polypane](https://polypane.app)), as well as a video showing all the demos from the article running in Polypane. - Source: Hacker News / about 2 months ago
  • ๐Ÿšช Donโ€™t Lock Users Out: A Practical Guide to Accessibility for Devs
    We also need to talk about Source Order vs. Tab Orderโ€”theyโ€™re more different than youโ€™d expect ๐Ÿ‘€. Source Order is the sequence of nxodes inside their parent in the DOM. Tab Order is the sequence of focusable nodes navigated using the Tab key. If a focusable element lacks tabindex, it follows a depth-first traversal of Source Order (visualized conceptually as a traversal path). Want to visualize Source Order?... - Source: dev.to / over 1 year ago

    That's pretty cool! Get ready to keep these up to date monthly or become obsolete quickly. One of the downsides of tools like this is that your URL needs to be available online so if there's an issue, your iteration loop is quite long. In Polypane [1] I've built social media previews that work with any local URL but also let you overwrite that URL for the social media that display those.
