Open Source Software Development Software

tmux is a terminal multiplexer: it enables a number of terminals to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached. This release runs on OpenBSD, FreeBSD, NetBSD, Linux, OS X and Solaris. tmux depends on libevent 2.x, and on ncurses. To build tmux, a C compiler (for example gcc or clang), make, pkg-config and a suitable yacc (yacc or bison) are needed. Some platforms provide binary packages for tmux.

Logtail is now part of Better Stack. Better Uptime and Logtail have been rebranded as Uptime and Logs on the Better Stack platform. Our mission is to help developers in building a better internet. And we believe that with the new fully integrated Better Stack platform, we’re simplifying the experience for the developers leveraging Better Stack even further. Formerly Logtail, lets you visualize your entire stack, turn your logs into structured data, and query everything like a single database with SQL. Customize retention per source to retain and query everything you want. No need to archive your logs to S3 anymore. Search all your logs anytime. See what metrics your teammates are looking at, comment on note-worthy data spikes and share log fragments with one click. Building a great software is a multiplayer game. Get answers fast with a powerful SQL query builder. No need to learn a new querying language or ask your data analyst.

Prettier, as a daemon, for improved formatting speed. Many parsers ship with prettierd, including JavaScript, TypeScript, GraphQL, CSS, HTML and YAML. Please notice that starting with version 0.12.0, prettierd now supports invoking the local version of prettier, so instead of adding new languages to prettierd, you should rely on that feature to use it locally with your custom version of prettier and enabled plugins.

Meriyah is a high-performance, fully compliant JavaScript parser that generates ESTree-compatible Abstract Syntax Trees (ASTs). Designed for speed and stability, it serves as an alternative to parsers like Acorn and Esprima.​

wasm4 is a WebAssembly-based game console for building and sharing games using WebAssembly. It provides a virtual platform with a defined specification for game development.

D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG, and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation. D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. For example, you can use D3 to generate an HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction. D3 is not a monolithic framework that seeks to provide every conceivable feature. Instead, D3 solves the crux of the problem: efficient manipulation of documents based on data. This avoids proprietary representation and affords extraordinary flexibility, exposing the full capabilities of web standards such as HTML, SVG, and CSS.

analyticsjs-boilerplate is a reference implementation for using Google Analytics analytics.js on modern websites. It collects best practices for tracking page views, user interactions, errors, performance metrics, and custom events in a structured way. The project was created to help developers avoid scattered analytics snippets and instead start from a cleaner, more maintainable setup. It includes patterns for organizing analytics logic, reporting useful metrics, and making implementation decisions more deliberate. While analytics.js itself is now a legacy Google Analytics library, the repository remains useful as a historical and educational reference for analytics architecture. Its main value is showing how to treat analytics as a thoughtful engineering layer rather than a pile of ad hoc tags.

Orange ORM is a lightweight, reflection-free ORM for Go that emphasizes performance and direct control. It provides a SQL-like fluent API and struct tagging system to map Go structs to database tables. Orange ORM supports PostgreSQL, MySQL, and SQLite, making it suitable for fast, embedded, or minimal-dependency applications.

Woke is a Python-based development and testing framework for Solidity. A testing framework for Solidity smart contracts with Python-native equivalents of Solidity types and blazing-fast execution. A property-based fuzzer for Solidity smart contracts that allows testers to write their fuzz tests in Python. See examples and documentation for more information. Fuzzer builds on top of the testing framework and allows efficient fuzz testing of Solidity smart contracts. Woke implements an LSP server for Solidity. The only currently supported communication channel is TCP.
