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.

Parcel features and specs

  • Zero Configuration
    Parcel requires minimal to no configuration to get started, making it extremely user-friendly, especially for beginners or small projects.
  • Fast Bundling
    Parcel uses worker threads to parallelize tasks, which significantly speeds up the bundling process compared to other bundlers that do not use this approach.
  • Out-of-the-box support for many file types
    Parcel supports many file types (e.g., JavaScript, CSS, HTML, images) right out-of-the-box without needing additional plugins or configurations.
  • Hot Module Replacement (HMR)
    Parcel offers built-in HMR, allowing developers to see changes in real-time without needing to refresh the browser, leading to a faster development cycle.
  • Tree Shaking
    Parcel automatically performs tree shaking, removing unused code from the production build to reduce file sizes, which can improve loading times.
  • Code Splitting
    Parcel has automatic code splitting capabilities which help to improve performance by loading only the necessary assets.
  • Extensible via Plugins
    Parcelโ€™s plugin system allows developers to extend its functionality easily if custom or additional features are needed.

Possible disadvantages of Parcel

  • Community and Ecosystem
    The community and ecosystem around Parcel are smaller compared to other bundlers like Webpack, so finding solutions and third-party plugins might be more challenging.
  • Limited Customization
    While the zero-config aspect is beneficial, it also means there are fewer customization options out-of-the-box, which might be limiting for complex projects needing specific configurations.
  • Performance with Large Projects
    For very large projects, Parcel's performance can become a bottleneck, particularly when it comes to initial build times.
  • Documentation
    The documentation, while improving, is not as comprehensive as some other tools, making it harder for developers to find detailed information when they encounter issues.
  • Dependency Bloat
    Parcel can sometimes include more dependencies than necessary in the final bundle, potentially increasing the final bundle size.

Loadster features and specs

  • Scalability
    Loadster can simulate thousands of users, which makes it useful for testing the performance of applications under high traffic conditions.
  • Detailed Reporting
    Loadster offers comprehensive and detailed reports, including real-time performance metrics, which help in identifying bottlenecks and issues quickly.
  • Easy Script Creation
    The tool provides an intuitive interface for creating and managing test scripts, making it accessible even for users with limited coding experience.
  • Cross-Platform Support
    Loadster supports various platforms, allowing users to test web applications on different browsers and devices.
  • Cloud-Based Execution
    Loadster allows for both on-premises and cloud-based test executions, providing flexibility in how tests are managed and run.

Rollup v. Webpack v. Parcel
Parcel's caching feature sees dramatically decreases in time consumption after the initial run. For frequent, small changes, in smaller projects **Parcel*8 is a great choice.

First impressions with Parcelย JS
The big selling point of Parcel though is that it offers a zero configuration experience. This means all the features are available out of the box! It also boasts blazing fast bundle times ๐Ÿ‘Ÿ You wonโ€™t be configuring how Parcel works or having to draft in various plugins to get started. If you do need something, Parcel magically detects this and will pull in stuff for you on...

Parcel vs webpack - Jakob Lind
Parcel has made their own benchmarks of Parcel and other bundlers. Parcel has been criticized because they have not made the benchmarks open source. People cannot verify that the benchmarks are true when they are not open source.

  • Bun 1.2 Is Released
    From its documentation [1] it looks a lot like a parceljs replacement [2], i.e. a zero config bundler which processes and bundles the dependencies in .html pages. So great for simple websites, not for replacing an entire Vite stack. [1] https://bun.sh/docs/bundler/fullstack [2] https://parceljs.org. - Source: Hacker News / over 1 year ago
