Project AIRI is the most popular open-source AI companion platform — a self-hosted recreation of Neuro-sama that brings AI-powered virtual characters into your world across web, desktop, and mobile. The system renders Live2D, Spine, and VRM 3D character models with auto-blink, eye tracking, and lip-sync driven by real-time voice synthesis, while the xsAI abstraction layer connects to 40+ LLM providers including OpenAI GPT-4, Anthropic Claude, Google Gemini, DeepSeek, and local models via Ollama and OpenRouter. Built from day one on WebGPU, WebAudio, Web Workers, WebAssembly, and WebSocket technologies, the browser version runs entirely client-side with PWA offline support while the server runtime enables persistent memory via PostgreSQL with pgvector embeddings and DuckDB WASM for client-side storage. The Minecraft agent plays autonomously using mineflayer with pathfinding, and a Factorio integration provides cooperative gameplay. Social integrations deploy your companion as a Discord bot joining voice channels, a Telegram bot, and a Twitter/X agent posting and replying autonomously. The desktop Stage Tamagotchi app provides an always-on-screen companion for Windows and macOS, while Stage Pocket brings the experience to mobile. Voice features include client-side speech recognition via VAD, multiple TTS providers including ElevenLabs, and screen vision capabilities. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

The moment after ShadowPlay saves a great clip is what Fireshare was built for: your friends see it now, not after a YouTube upload, processing queue, and platform terms review. Drop videos into a watched folder and this Flask/React application generates a unique shareable URL for each one, complete with Open Graph metadata - so pasting the link into Discord, Twitter, or Slack produces a proper embed with title, description, and video thumbnail instead of a raw URL. Viewers need no account and no app. Visibility is per-file: public (browseable on your feed), private (unlisted, reachable only by direct link), or password protected. For game clips specifically, Fireshare organizes automatically - clips sort by game with cover art pulled from SteamGridDB, no manual tagging - while tags and full-library search cover everything else. Optional transcoding (CPU or GPU) creates lower-quality renditions so viewers on weak connections get automatic quality adaptation, and video cropping trims clips in place. The extras round out a genuinely finished tool: view counters, timestamped share links, a shuffle button, restrictable uploads, Discord notifications for new videos, an RSS feed of the public feed, mobile support, and LDAP for multi-user setups. No storage limits, no watermarks, no platform deciding what stays up. GPL-licensed.
