Openshorts: Open-source / self hosted AI clip generator (OpusClip alternative)

OpenShorts is an MIT-licensed, self-hostable tool that turns long videos into 9:16 shorts using Gemini for viral moment detection, faster-whisper subtitles, and AI reframing modes including face tracking and split-screen layouts. It also bundles an AI Shorts UGC creator and a YouTube Studio toolkit, and exposes the pipeline via an MCP server, REST API, webhooks and CLI. Self-hosting is free with bring-your-own API keys, while a hosted cloud plan starts at $12/mo after a watermarked 20 min/mo free tier.
