A Local Video Studio Inside Your Coding Agent — No API Keys, No Uploads

Showtime is a free, MIT-licensed open-source tool that turns a coding agent like Claude Code into a local video studio. You describe what you want in one sentence—"Make a 20-second launch video with a voice-over and upbeat music"—and the agent directs the whole thing: motion graphics, captions, background music, sound design, and a finished MP4. Everything renders on your own machine. No cloud AI services, no API keys, and no uploading customer footage to a third party.

Why this matters for a small business: video gets attention, but paying an agency or freelancer for every launch clip, explainer, or social reel adds up fast. With Showtime, recurring video work becomes repeatable. A tax preparer could generate a short motion graphic each tax season explaining what changed. A real estate agent could turn a listing into a 30-second narrated walkthrough. A local gym could produce membership promo reels from a few bullets. The finished videos include captions and voice-over, so they're ready for social platforms.

The trade-off: this is still developer-adjacent tooling. You need a machine comfortable with the command line, and the first setup downloads about half a gigabyte. But once it's running, the cost per video is zero dollars in API fees—just your time and electricity. For businesses that need a steady stream of short videos, that math is hard to beat.
