A high-performance, multiplayer code editor from the creators of Atom and Tree-sitter. Available on macOS, Linux, and Windows.

• Built by the same team behind Atom and Tree-sitter.
• Download it directly or install through a package manager on macOS, Linux, and Windows. A web version is not available yet.

Context layer so AI agents use enterprise data correctly

An NVIDIA library that builds a context layer from metadata, reconciles definitions across systems, and serves it to agents through MCP, CLI, and API.

• The flow is discover, ground, validate, expose, then learn from certified corrections.
• Generated queries are checked against certified definitions and lineage, and every answer returns its provenance.
• Supports natural-language questions to databases through NVIDIA NIM, with a web UI, Helm chart, and Docker Compose.

Full-stack web framework built on the MVC pattern

A framework for database-backed web applications using Model-View-Controller. It includes Active Record, Action View, and Action Pack.

• Models use Active Record, or plain Ruby classes through Active Model.
• Views are templates, usually HTML with embedded Ruby in ERB files.
• Controllers handle HTTP requests routed by Action Dispatch.

Free command line media player

A free media player that runs from the command line and supports many file formats, audio and video codecs, and subtitle types.

• Runs on recent Linux, Windows 10 1607 or later, and macOS 10.15 or later.
• Hardware decoding is off by default and must be enabled with the --hwdec option. On weak GPUs, --profile=fast is recommended.

Main source repository of Rust: compiler, standard library, docs

The main source repository for the Rust language. It holds the compiler, standard library, and documentation, with a focus on performance, reliability, and productivity.

• The type system and ownership model ensure memory and thread safety at compile time.
• Fast and memory-efficient, and easy to integrate with other languages.
• Comes with documentation, compiler diagnostics, and tooling including a package manager and build tools.

JavaScript library for building web and native interfaces

A JavaScript library for building user interfaces. Views are declarative per state, and React updates the right components when data changes.

• Declarative: write simple views for each state, and React updates only the parts that need it.
• Component-based: components manage their own state and compose into complex UIs.

Platform for building mobile and desktop web applications

A development platform for mobile and desktop web applications using TypeScript or JavaScript. Documentation lives at angular.dev.

• The docs cover components and templates, forms, the API, and architecture.
• Advanced topics include Angular Elements, server-side rendering, schematics, lazy loading, and animations.

PHP framework and a set of reusable PHP components

A PHP framework for web and console applications, and a set of reusable PHP components. Installed with Composer.

• Follows semantic versioning strictly and publishes Long Term Support (LTS) versions.
• A Symfony Demo app teaches by example, and a Getting Started guide covers the basics.

Monitoring system and time series database

A service monitoring system that collects metrics from targets at set intervals, evaluates rules, displays results, and triggers alerts.

• Multi-dimensional data model: time series are defined by metric name and key/value pairs, queried with PromQL.
• Collects data over an HTTP pull model. Time series can also be pushed through an intermediary gateway for batch jobs.
• Targets are found through service discovery or static configuration.

Agent Skills for Google products and technologies

A collection of Agent Skills for Google products and technologies, including Google Cloud. Installed into agents through npx skills.

• During install, pick specific skills or all of them, the target agents, and project or global scope.
• Update installed skills with npx skills update.

Repo where Microsoft and the community build VS Code

The Code - OSS repository, where Microsoft develops the Visual Studio Code product together with the community. The code is MIT licensed.

• Code, issues, the roadmap, monthly iteration plans, and endgame plans are published here and on the wiki.
• The repository is developed in the open with the community.

A new shell that treats data as structured tables

A shell that sees each input as structured data, not raw text. Commands like ls return a table that can be piped through a pipeline.

• Inspired by PowerShell, functional languages, and modern CLI tools.
• Many people use it daily, but some commands may be unstable and the design can still change.

Distributed key-value store for critical system data

A reliable distributed key-value store written in Go. It uses the Raft consensus algorithm to manage a highly available replicated log.

• Simple (gRPC API), secure (automatic TLS with optional client cert authentication), fast, and reliable.
• The README cites a benchmark of 10,000 writes per second and notes frequent use alongside Kubernetes.
• The main branch may be unstable during development, so use releases for stable versions.

TLS toolkit and general purpose cryptography library

An open source toolkit for the TLS, DTLS, and QUIC protocols, with a cryptographic library that can also be used on its own. Includes a FIPS-validated module.

• Made of libssl for protocols, libcrypto for cryptography, and the openssl command line tool.
• The openssl tool creates keys, X.509 certificates, CSRs, and CRLs, and computes digests and encrypts data.

Small, composable agent skills for engineers

A set of agent skills from Matt Pocock for everyday software engineering. Small, easy to adapt, composable, and usable with any model.

• Install as a self-updating plugin, or copy editable files through skills.sh.
• Available for Claude Code, Codex, GitHub Copilot, Gemini CLI, and other agents through npx.

Agent skill for six-phase security audits with verified findings

A coding-agent skill that runs a structured security audit in six phases, from recon to report. It seeded Cloudflare's vulnerability discovery harness.

• Each candidate finding goes to a fresh verifier that tries to disprove it.
• Results are written to findings.json as confirmed, needs_validation, or rejected, then checked against report-schema.json.
• The final REPORT.md is derived from the verified records.

Extremely fast Python linter and formatter written in Rust

A Python linter and formatter written in Rust, claimed to be 10 to 100 times faster than Flake8 and Black. Installable via pip.

• Over 900 built-in rules, pyproject.toml support, and automatic fixes such as removing unused imports.
• Can replace Flake8, Black, isort, and other tools, with built-in caching and editor integrations.
