Cross-platform: Linux, Windows, macOS.

Microsoft PowerToys is a suite of 30+ free Windows utilities for power users, including FancyZones for custom window layouts, a quick launcher, batch rename, color picker, screen OCR, keyboard remapping, cross-PC mouse control, and more—streamlining workflows and boosting productivity.

Ventoy is an open-source tool for creating bootable USB drives. Simply copy ISO/WIM/IMG/VHD(x)/EFI files to the drive and boot them directly without reformatting. Supports Legacy BIOS, UEFI, and multiple architectures.

OBS Studio is a free and open-source application for video capturing, compositing, encoding, recording, and live streaming. Designed for efficiency, it supports a wide range of sources and plugins, making it a powerful tool for content creators, streamers, and educators across Windows, macOS, and Linux.

Redis is the preferred, fastest, and most feature-rich cache, data structure server, and document and vector query engine for building real-time data-driven applications.

A local-first code knowledge graph for AI coding agents. Pre-indexes symbol relationships, call graphs, and code structure into a local SQLite database, enabling agents like Claude Code, Cursor, Codex CLI, and OpenCode to query code semantically — reducing tool calls by ~70% and cost by ~35% without sending data externally. Supports 19+ languages and 13 web frameworks.

FFmpeg is a complete, cross-platform solution for recording, converting, and streaming audio and video. It includes libraries for codec implementation, format handling, filtering, and tools like ffmpeg, ffplay, and ffprobe for multimedia processing.

Git is a fast, scalable, distributed version control system designed to handle projects of all sizes with speed and efficiency. It provides a rich command set for both high-level operations and full access to internals, originally created by Linus Torvalds.

tmux source code

A high-performance code intelligence MCP server written in pure C. Indexes repositories into a persistent knowledge graph supporting 158 languages via tree-sitter and Hybrid LSP type resolution for 11 languages. Provides sub-ms Cypher queries, call tracing, dead code detection, and cross-service HTTP linking. Ships as a single static binary with zero dependencies, compatible with 11 AI coding agents including Claude Code and Gemini CLI.
