Backstage
Backstage is an open platform for building developer portals
Powered by a centralized software catalog, Backstage restores order to your infrastructure and enables your product teams to ship high-quality code quickly, without compromising autonomy. At Spotify, we've always believed in the speed and ingenuity that comes from having autonomous development teams. But as we learned firsthand, the faster you grow, the more fragmented and complex your software ecosystem becomes. And then everything slows down again. By centralizing services and standardizing your tooling, Backstage streamlines your development environment from end to end. Instead of restricting autonomy, standardization frees your engineers from infrastructure complexity. So you can return to building and scaling, quickly and safely. Every team can see all the services they own and related resources (deployments, data pipelines, pull request status, etc.) -

Bolt for JavaScript
A framework to build Slack apps using JavaScript
A JavaScript framework to build Slack apps in a flash with the latest platform features. Read the getting started guide to set-up and run your first Bolt app. To listen to messages that your app has access to receive, you can use the message() method which filters out events that aren’t of type message. message() accepts an optional pattern parameter of type string or RegExp object which filters out any messages that don’t match the pattern. A RegExp pattern can be used instead of a string for more granular matching. Within your listener function, say() is available whenever there is an associated conversation (for example, a conversation where the event or action which triggered the listener occurred). say() accepts a string to post simple messages and JSON payloads to send more complex messages. The message payload you pass in will be sent to the associated conversation. -

Ionicons
Hand-crafted icons built by Ionic for web apps
Premium designed icons for use in web, iOS, Android, and desktop apps. Support for SVG and web font. Completely open source, MIT licensed and built by Ionic. Ionicons is a completely open-source icon set with 1,300 icons crafted for web, iOS, Android, and desktop apps. Ionicons was made for Ionic Framework, a cross-platform hybrid and Progressive Web App framework. The Ionicons Web Component is an easy and performant way to use Ionicons in your app. The component will dynamically load an SVG for each icon, so your app is only requesting the icons that you need. Also note that only visible icons are loaded, and icons which are "below the fold" and hidden from the user's view do not make fetch requests for the svg resource. If you're using Ionic Framework, Ionicons is packaged by default, so no installation is necessary. -

Passmark
The open-source Playwright library for AI browser regression testing
The Passmark project is an open-source AI-powered regression testing framework built on top of Playwright that enables developers to write end-to-end browser tests using natural language instead of traditional scripting. It is designed to simplify and accelerate testing workflows by allowing AI models to interpret human-readable instructions and translate them into executable browser actions. One of its defining features is a cache-first execution model, where AI is used initially to discover how to perform actions, and those actions are then stored and replayed at native speed in future runs. This approach significantly reduces reliance on AI during repeated test executions, improving both performance and cost efficiency. The framework also incorporates multi-model validation, using multiple AI systems to verify assertions and reduce the risk of incorrect results. -

ARK
Unstyled, accessible UI components for your design System
Ark is a headless UI component library designed to provide the foundational logic required to build scalable and accessible design systems for modern web applications. The project focuses on separating component behavior from visual styling so developers can implement their own design language without being constrained by predefined styles. Built on top of Zag.js state machines, Ark delivers predictable and robust component logic that works consistently across multiple JavaScript frameworks. It supports React, Solid, Vue, and Svelte, enabling developers to share component behavior across ecosystems while maintaining framework-specific implementations. Because the components are headless, developers bring their own CSS frameworks, styling solutions, or design tokens, which makes the library highly adaptable for custom UI systems. -

Styled Components
Visual primitives for the component age
Visual primitives for the component age. Use the best bits of ES6 and CSS to style your apps without stress. Utilising tagged template literals (a recent addition to JavaScript) and the power of CSS, styled-components allows you to write actual CSS code to style your components. It also removes the mapping between components and styles, using components as a low-level styling construct could not be easier! Alternatively, you may use style objects. This allows for easy porting of CSS from inline styles, while still supporting the more advanced styled-components capabilities like component selectors and media queries. styled-components is compatible with both React (for web) and React Native, meaning it's the perfect choice even for truly universal apps! If you're using tooling that has babel-plugin-macros set up, you can switch to the styled-components/macro import path instead to gain the effects of the babel plugin without further setup. -

Ultracite
A highly opinionated, zero-configuration linter and formatter
Ultracite is a highly opinionated, zero-configuration linting and formatting preset designed primarily for modern JavaScript/TypeScript codebases. It is built on top of the Biome toolchain (written in Rust) and aims to deliver sub-second performance so that formatting and linting feel seamless, even on large projects. Because it comes pre-configured with sensible defaults for frameworks like React and Next.js, developers can adopt it with minimal setup—simply run npx ultracite init and start coding. The project emphasizes type-safety and best practices, enforcing stricter rules out of the box so that unsafe or sloppy patterns are discouraged. It also positions itself as “AI-ready,” meaning it’s designed to integrate smoothly into workflows where AI code generation (e.g., from Copilot, Claude Code, etc) is involved, ensuring consistent style across team-written and machine-written code. -
25
User Agents
A JavaScript library for generating random user agents with data
User Agents is a JavaScript library that generates realistic and up-to-date user agent strings and browser fingerprints based on real-world usage data. The library is designed to help developers simulate authentic browser traffic patterns, which is particularly useful in web scraping, testing, and automation scenarios. Unlike simpler random user agent generators, it uses frequency-weighted datasets to ensure that generated values reflect how browsers are actually used in the wild. The dataset is updated automatically on a daily basis, ensuring that generated user agents remain current and relevant over time. In addition to user agent strings, the library can produce detailed browser fingerprint data such as screen size, platform, connection type, and device category. It also includes flexible filtering capabilities that allow developers to generate user agents matching specific criteria such as device type, operating system, or browser version.
