VibeVoice is a novel open-source framework for generating expressive, long-form, multi-speaker conversational audio like podcasts from text. It solves key challenges in traditional TTS systems, such as scalability, speaker consistency, and natural turn-taking, by using continuous speech tokenizers and a next-token diffusion framework. This model is designed for researchers and developers in the speech synthesis community who need to create realistic, multi-participant audio content.

Faceswap is a free, open-source software application powered by TensorFlow, Keras, and Python, designed for creating deepfake videos and images. It solves the problem of accessing advanced face-swapping technology by providing a powerful, community-supported tool that runs on Windows, macOS, and Linux. It is for digital artists, video editors, researchers, and enthusiasts who want to explore or utilize deepfake technology in an accessible and ethical framework, supported by comprehensive guides and an active forum.

Snipe-IT is a free, open-source IT asset and license management system designed to replace error-prone spreadsheets. It provides a powerful, user-friendly platform for businesses to track hardware, software licenses, and accessories with robust security features baked in. It's ideal for IT teams, system administrators, and organizations of any size looking for a transparent, vendor lock-in-free solution to manage their technology assets.

jcode is an open-source terminal coding agent written in Rust, designed as a harness to maximize the capabilities of AI models. It tackles the limitations of current AI benchmarks and agent systems by focusing on scaling test-time compute, parallelism, and memory for continual learning. It's built for developers and researchers who want a powerful, transparent, and efficient general-purpose dev tool for day-to-day work and advancing agent capabilities.

BlackFlare - a native macOS menu bar app for Claude Code and Codex. Keep your Mac awake during long runs, get notified when a session finishes or needs you, switch your defaults from the menu, and watch plan usage — all on-device.

Turn a product photo or store URL into launch-ready AI video and image ads. Fully automatic. We launch them to Meta. No credit card.

A simple native macOS terminal built with Swift and libghostty. Minimal be design - suited for everyday use, just not packed with the bells and whistles power users expect.

MemoryCustodian gives Codex, Claude Code, Gemini, and other coding agents durable project memory—without a hosted service or bloating every prompt. Decisions, constraints, rejected approaches, and project context live as plain Markdown in your repo, where they can be reviewed, versioned, shared, and deleted like code. A manifest loads only the memory relevant to each task. Open source, local-first, and cross-agent.

EQK is the first Mac app with dynamic AI EQ - an equalizer that re-tunes itself per song in real time. Give every app its own EQ, headphone correction, and output device. No virtual drivers - just native macOS audio capture. 10-band parametric Tone Desk, 3,985+ AutoEq headphone profiles, per-app limiter, full signal-chain metering, and a free built-in FLAC player with synced lyrics for the songs that you own. 100% local, no telemetry, no subscription.
