3DCellForge
AI-powered interactive 3D cell generation and exploration studio
3DCellForge is an AI-powered 3D cell generation and exploration studio built as a polished browser prototype. It uses React, Vite, Three.js, React Three Fiber, Drei, and Framer Motion to create an interactive WebGL environment for exploring biological cell models. Users can rotate, zoom, inspect organelles, compare views, take notes, capture screenshots, and export or import GLB models. The project also supports optional image-to-3D generation through cloud providers and local backends, while keeping API keys on the server side instead of exposing them in the frontend bundle. It includes cached demo models so the experience can work without generating a new model every time. Overall, it is a creative research and education tool for visualizing cell structures in a more interactive way than static diagrams. -

500 Lines or Less
Source for the book 500 Lines or Less
500 Lines or Less is the source repository for the fourth book in the Architecture of Open Source Applications series. The project focuses on small but meaningful programs that solve classic software engineering problems in no more than 500 lines of source code. Its goal is to make software design lessons easier to study by using compact, readable examples instead of large production systems. Each chapter walks through design decisions, tradeoffs, module boundaries, interfaces, and extension points. The book is especially useful for developers who want to understand how experienced programmers think while building real systems. It works as both an educational text and a practical reference for studying architecture through code. -

ADAMANT JavaScript API library
ADAMANT Javascript API library
ADAMANT JavaScript API is a library intended to interact with ADAMANT blockchain for JavaScript developers. Also ADAMANT Console and ADAMANT node Direct API are available. JS API shows decentralization in action, if a network node cannot fulfill your request, the library will redirect it to another node, and so on several times. You will get the result and you do not need to think about processing the request. Health Check system pings all nodes in the list using /status endpoint, and connects to a node with actual height. When the library is unable to process requests with the current node, it forces to re-initialize Health Check. -

AST explorer
A web tool to explore the ASTs generated by various parsers
Paste or drop code into the editor and inspect the generated AST. Depending on the parser settings, it not only supports ES5/CSS3. Since the future syntax is supported, the AST explorer is a useful tool for developers who want to create AST transforms. In fact, transformers are included so you can prototype your own plugins. Save and fork code snippets. Copy the URL to share them. Copying an AST or dropping a file containing an AST into the window will parse the AST and update the code using escodegen. Otherwise, the content of the text editor will be replaced with the content of the file (i.e. you can drag and drop JS files). Choose between multiple parsers and configure them. shift+click on a node expands the full subtree. Hovering over a node highlights the corresponding text in the source code. Editing the source or moving the cursor around will automatically highlight the corresponding AST node (or its ancestors of it isn't expanded). -

Advanced REST Client application
Advanced REST Client - Desktop application
This is the main repository for the ARC Electron application. If you are still using Chrome plug-in then proceed to move From Chrome To the Desktop Client section. The original Chrome application is discontinued as Chrome stopped supporting browser-based applications. ARC was built as an open-source and free for everyone API tool out of a passion for giving the developer community tools they need. The application and related projects (like API Console) are created and distributed to our users for free. Our vision is that API tools are available for every developer and organization, regardless of their size, for free and without forced relationship. API tools are using open standards to communicate with other applications so developers can build integrations. Originally the application was created by the author for own convenience while developing APIs. It quickly turned out to be a common problem among developers to consume APIs during the development process. -

Alfy
Create Alfred workflows with ease
Alfy offers the possibility of caching data, either with the fetch or directly through the cache object. An important thing to note is that the cached data gets invalidated automatically when you update your workflow. This offers the flexibility for developers to change the structure of the cached data between workflows without having to worry about invalid older data. You can remove these properties from your info.plist file as they are being added automatically at install time. When developing your workflow it can be useful to be able to debug it when something is not working. This is when the workflow debugger comes in handy. You can find it in your workflow view in Alfred. Press the insect icon to open it. Alfred lets users set environment variables for a workflow which can then be used by that workflow. This can be useful if you, for example, need the user to specify an API token for a service. You can access the workflow environment variables from process.env. -

Animatable
One property, two values, endless possiblities
Animatable is an interactive web gallery that demonstrates which CSS properties can transition between two values. Each tile represents one property and continuously alternates between a defined starting and ending state. Visitors can animate every example at once or trigger individual demonstrations by hovering. Selecting a tile reveals the property name, both values, authorship information, and controls for moving to adjacent examples. Keyboard navigation supports Escape and the arrow keys for faster exploration. The page generates its keyframes dynamically with JavaScript and applies compatibility fixes through StyleFix. It serves as a visual reference and experimental showcase rather than a general-purpose animation library. -

AutoCannon
fast HTTP/1.1 benchmarking tool written in Node.js
An HTTP/1.1 benchmarking tool written in node, greatly inspired by wrk and wrk2, with support for HTTP pipelining and HTTPS. If the PORT environment variable is set, the URL can be a path. Use a warm up interval before starting sampling. This enables startup processes to finish and traffic to normalize before sampling begins. There are two tables, one for the request latency, and one for the request volume. The latency table lists the request times at the 2.5% percentile, the fast outliers; at 50%, the median; at 97.5%, the slow outliers; at 99%, the very slowest outliers. Here, lower means faster. When in workers mode, you need to pass in an absolute file path to all the options that accept a function. This is because a function passed into the main process can not be cloned and passed to the worker. So instead, it needs a file that it can require. When combining a fixed amount of requests with concurrent connections and an overallRate limit, autocannon will distribute the requests. -

Autoprefixer
Parse CSS and add vendor prefixes to CSS rules by Can I Use
PostCSS plugin to parse CSS and add vendor prefixes to CSS rules using values from Can I Use. It is recommended by Google and used in Twitter and Alibaba. Write your CSS rules without vendor prefixes (in fact, forget about them entirely). Autoprefixer will use the data based on current browser popularity and property support to apply prefixes for you. You can try the interactive demo of Autoprefixer. Autoprefixer uses Browserslist, so you can specify the browsers you want to target in your project with queries. It can help you get prefixes for: animations, transition, transform, grid, flex, flexbox and others. You can configure which browsers to generate prefixes for in the distribution. The IE grid layout polyfill is enabled, which is not by default in autoprefixer. Autoprefixer can be used to translate modern CSS Grid syntax into IE 10 and IE 11 syntax, but this polyfill will not work in 100% of cases. This is why it is disabled by default. -

Better Harness
Help your coding agents get better at getting better
Better Harness is an open-source evaluation system for improving the workflows used by AI coding agents. Instead of reviewing only the final code change, it examines how an agent understood the task, executed work, validated results, delivered safely, and captured reusable lessons. It gathers project and session evidence while marking missing or unobserved behavior explicitly. Reports organize findings across five Agent Work Loop dimensions and connect each conclusion to visible supporting evidence. Supported gaps become prioritized recommendations with expected outcomes, repair boundaries, and acceptance checks. Repeated reports can be compared through a history view to observe workflow trends without claiming unsupported causation. Better Harness supports Claude Code, Codex, Qoder, and Cursor through host-specific plugins, commands, and report formats. -

CF-Workers-SUB
Aggregates any of your nodes with multiple subscriptions
CF-Workers-SUB is a project that uses Cloudflare Workers to aggregate or convert multiple subscription sources (for proxy nodes/configs) into a personalized subscription link for the user. Essentially, it lets you input your own node(s) and then generate a unified subscription endpoint that others can use with tools like Clash, Sing-box, or V2Ray. The repository emphasizes being user-friendly for scenarios where one has many proxy/node links but wants to streamline into a single subscription feed. It also supports variable configuration (token, built-in nodes, custom add/CSV/API sources) to produce automated “preferred line” generation. The project is aimed at “subscription” style services (i.e., providing proxies as subscriptions) rather than pure application logic, and is tailored toward self-hosters. It’s designed for ease of deployment on Workers or Pages, enabling people to maintain their own subscription link infrastructure cheaply. -
