Documentation
OpenShorts.app
Open source AI video platform with 3 tools in one: Clip Generator, AI Shorts (UGC videos with AI actors), and YouTube Studio.
Two ways to run it, same software either way:
| Self-hosted (this repo) | Hosted on openshorts.app | |
|---|---|---|
| Price | Free forever, MIT | Free plan, paid from $12/mo |
| Speed | 5 to 8 min per 8-min video on CPU | About 50s on our NVIDIA GPU |
| API keys | Bring your own Gemini, ElevenLabs, fal.ai | Gemini included, nothing to set up |
| Watermark / limits | None, ever | Watermark and 20 min/mo on the free plan, neither on paid |
| Setup | Docker, 8GB+ RAM, model downloads | Sign in and paste a link |
| MCP / API for agents | Same /mcp endpoint, but only while your machine is on | Always-on endpoint at mcp.openshorts.app, API keys in one click |
| Your data | Your server | Ours |
Self-hosting is genuinely free and always will be. It costs you a machine, your own API keys and the time to keep it running. The hosted plans exist to cover that hardware and those keys, not to unlock features.

How Much Does It Cost?
Self-hosting OpenShorts is free. You provide the machine and you only pay for the AI APIs you use, and most have generous free tiers:
| Service | Free Tier | Paid Cost | Used For |
|---|---|---|---|
| Google Gemini | Free trial with generous limits | < $0.01 per 10-min video | Viral moment detection, script generation, web research |
| fal.ai | Pay-per-use | ~$0.50-1.50 per AI Short | Actor generation, talking head video, lip-sync |
| ElevenLabs | Free tier available | Pay-per-use | Voiceover, voice dubbing |
| Upload-Post | 10 free uploads/month to all networks (no credit card) | Pay-per-use | Auto-publishing to TikTok, Instagram, YouTube |
| AWS S3 | Optional | ~$0.023/GB | Cloud backup for clips and gallery |
Bottom line: You can clip videos for practically free with Gemini, and publish 10 videos/month to all social networks at zero cost with Upload-Post.
Don't want to run any of that? openshorts.app is the same software on our hardware: our NVIDIA GPU clips an 8-minute video in about 50 seconds instead of the 5 to 8 minutes it takes on a typical CPU, the Gemini key is included, and auto-publishing is already wired up. Free plan is 20 minutes a month with a watermark and no credit card; paid plans start at $12/mo for 100 minutes without watermark.

Automate It: MCP Server, REST API and Webhooks
You don't need the dashboard. The whole pipeline is callable by AI agents and scripts.
MCP server (/mcp)
OpenShorts ships a built-in MCP server, so Claude, ChatGPT, Cursor or any MCP client can clip and publish videos for you:
# Hosted (create an API key in your account page at openshorts.app):
claude mcp add --transport http openshorts https://mcp.openshorts.app/mcp \
--header "Authorization: Bearer osk_..."
# Self-hosted (no key needed, BYOK rules apply):
claude mcp add --transport http openshorts http://localhost:8000/mcp
Tools: process_video, get_job_status, list_clips, get_quota, add_subtitles, publish_clip. A prompt like "clip this podcast and schedule the best 3 to TikTok" is now a one-liner in your agent of choice.
REST API + API keys
Hosted accounts can mint osk_... API keys (account page). A key authenticates as you everywhere — same plan, same minutes, same job ownership:
curl -X POST https://api.openshorts.app/api/process \
-H "Authorization: Bearer osk_..." -H "Content-Type: application/json" \
-d '{"url": "https://youtube.com/watch?v=...", "acknowledged": true,
"webhook_url": "https://your-server.com/hooks/openshorts"}'
Interactive docs at /docs (OpenAPI) on any instance.
Completion webhooks
Pass webhook_url (and optionally webhook_secret) to POST /api/process and you get exactly one POST when the job reaches a terminal state — no polling loops in your n8n / Zapier / cron pipelines:
{"event": "job.completed", "job_id": "…",
"clips": [{"index": 0, "title": "…", "video_url": "…", "download_url": "…"}]}
With a secret, the body is signed: X-OpenShorts-Signature: sha256=<hmac-sha256(body)>.
