ping.gg

OBS Studio is free, open-source software for video recording and live streaming on Windows, macOS, and Linux. It captures and mixes video and audio in real time, using scenes composed of sources such as window captures, images, text, browser windows, webcams, and capture cards; these sources can include a ping.gg call participant as a stream layer. It provides scene transitions, per-source audio filters, VST plugin support, hotkeys, Studio Mode for previewing productions, Multiview monitoring, and an API with native plugin and Lua or Python scripting support.

Gamma is a web-based presentation and document platform that uses generative AI to help create and edit slides and visual documents. It is developed and offered under the Gamma brand as an online productivity tool for creating presentations and shareable documents.

omg.dev is an open-source, self-hosted parallel coding-agent harness and control plane developed by BennyKok. It runs coding-agent sessions on a local computer or hosted Computer, keeps them running when the web interface disconnects, and provides a single web UI for parallel sessions, transcript reading, follow-up instructions, chats, bots, schedules, and notifications. The project supports agents including Claude Code, Codex, Grok, Cursor, OpenCode, Jcode, GitHub Copilot, and Pi, using the user's existing agent subscriptions or API keys. Local installations run through a Bun CLI and expose the interface on localhost; remote phone access can be provided through Tailscale. The repository is licensed under the MIT License.

Hopp is an open-source remote pair-programming and screen-sharing application for developers. Its native desktop client uses Tauri with Rust and React/TypeScript, while a Go backend uses PostgreSQL and Redis; screen sharing runs over WebRTC infrastructure powered by LiveKit. The application supports one-click pairing, rooms for up to 10 participants, and the project claims sub-100ms latency. It can be used through Hopp's managed cloud or self-hosted with Docker Compose, which provisions PostgreSQL, Redis, LiveKit, and Caddy. macOS is supported with a stable build, Windows with an alpha build, and Linux is planned.

It's Giving is an open-source Python webcam application that recognizes facial expressions, hand gestures, and body positions, then overlays matching meme images or animated GIFs on the user's head. It uses MediaPipe face landmarks and blendshapes, hand points, body landmarks, face-relative measurements, tongue color, and hand speed; its calibrated version records seven seconds of the user's neutral expression and evaluates later expressions as deviations from that baseline. An ordered pose-matching pass requires gestures to persist for a configured number of frames before triggering, and the overlay follows the user's face with alpha compositing and animation support. The application publishes the result through a virtual camera for Zoom, Meet, Teams, Discord, OBS, and other webcam-compatible software. It includes fourteen predefined reactions, preview-only and virtual-camera modes, keyboard testing and recalibration controls, and an assets directory where users can replace or add reaction images. It runs with Python 3.11 or 3.12 and requires a virtual-camera backend such as OBS Studio or v4l2loopback, depending on the operating system.
