Selenium
Software Freedom Conservancy
Selenium automates browsers. That's it! What you do with that power is entirely up to you.

If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point. -

Foldwrap
Foldwrap
Foldwrap is an AI-powered animated banner ad generator that transforms simple text prompts or static designs (for example, from Figma) into production-ready animated HTML5 banners or video ads in seconds. You can start from scratch by describing your ad concept in natural language, including text, colors, product details, and brand elements, and Foldwrap will build a complete animated ad with visuals, motion, and layout. Alternatively, if you already have a design in Figma, you can import it with Foldwrap’s plugin and instantly animate frames: the tool automatically handles animation of every element, merges multi-frame storyboards into smooth sequences, and produces native HTML5/CSS output (or MP4/video) optimized for performance, cross-browser compatibility, and ad-network compliance. Foldwrap also supports AI-powered resizing and format adaptation, letting you quickly generate multiple ad variants for different screen sizes or platforms.Starting Price: $30 per month -

Three.js
Three.js
Three.js is a JavaScript 3D library. The aim of the project is to create an easy-to-use, lightweight, cross-browser, general-purpose 3D library. The current builds only include a WebGL renderer but WebGPU (experimental), SVG and CSS3D renderers are also available in the examples. To actually be able to display anything with three.js, we need three things, scene, camera, and renderer, so that we can render the scene with the camera. In addition to the WebGLRenderer, Three.js comes with a few others, often used as fallbacks for users with older browsers or for those who don't have WebGL support for some reason. Create a loop that causes the renderer to draw the scene every time the screen is refreshed (on a typical screen this means 60 times per second). Anything you want to move or change while the app is running has to go through the animate loop. You can of course call other functions from there.Starting Price: Free -

AegisRunner
AegisRunner
AegisRunner is a cloud-based, AI-powered autonomous regression testing platform for web applications. It combines an intelligent web crawler with AI test generation to eliminate manual test authoring entirely. What It Does AegisRunner takes a single input — a URL — and autonomously: Crawls the entire web application using a headless Chromium browser (Playwright), discovering every page, interactive element, form, modal, dropdown, accordion, carousel, and dynamic state. Builds a state graph of the application, where each node is a distinct DOM state and each edge is a user interaction (click, hover, scroll, form submission, pagination). Generates complete Playwright test suites using AI (supporting OpenRouter, OpenAI, and Anthropic models) from the crawl data — no manual test writing required. Executes those tests and reports pass/fail results with detailed per-test-case reporting, screenshots, and traces. It achieves a 92.5% pass rate across 25,000+ auto-generated tests.Starting Price: $9 -
