Runs in Claude Code or Codex
Install OpenMontage as a plugin and it runs inside the agent you already use - a toolset in your terminal, not another app to run. We never meter your local work.
Open-source agentic video production
Make video the way you now make software.
Give it a brief and your materials. The agent plans the story, generates paid images and clips when they are needed, and creates animation and sources B-roll at no cost. Then it narrates, captions, renders and reviews the finished, editable video - every step yours to direct.
- Runs on Claude Code, Codex or OpenCode
- Compose and render on your own machine
- Nothing spends until you approve it

The pipeline
Editors edit footage you have. Generators make clips. OpenMontage produces the video.
Every stage runs in the open, with the artifact it produces written to your project. Eight stages are free; only generation is metered.

Give the context that shapes the brief.
Audience, duration, tone and the messages that have to land. The brief becomes a document the agent works from - not a prompt that disappears.

The gate
Nothing spends until you approve.
Full script, scene plan and a line-item cost estimate arrive together. Every generate action shows its price before you click, and failed generations auto-refund.
- Budget governance built into the pipeline, not bolted on
- Swap a generated scene for stock and the estimate updates
- Failed generations refund automatically

Agent-native
It runs where you already work.
Install the plugin and your agent chat becomes the production chat. The engine ships once as an MCP toolset - one toolset, whichever harness you use.
No subscription? Still welcome
OpenCode with open models takes it down to fully free and fully local. Bring your own keys and providers. Nobody is turned away.
Or skip the terminal entirely
The same production board opens in OpenMontage Studio - a warm desktop workspace over the same engine. Free for everyone.
The desktop app
A warm production board over the same engine.
Storyboard, script, approvals and renders in one place. Chat steers everything, and every card the agent makes is something you can read and question.

The posture
Open where it counts.
The engine is open source and public. The project format is published, so your productions are plain files that stay yours. Studio is free for everyone - you pay only for generation through our cloud, and you always see the price first.
Local-first
Your footage never leaves your machine. Composition and rendering happen on it.
Bring your own agent
Claude Code, Codex or OpenCode. Bring your own keys and providers too - always allowed, always free.
Budget governance built in
Every generate action shows its cost before you click, and failed generations auto-refund.
No watermarks. Ever.
Nothing on your own compute is metered, capped or stamped - all resolutions, commercial use, every tier.
Steerable at every step
Brief, script, scene plan - every artifact the agent makes is a document you can read, question and change.
Open engine & format
The engine is open source and the project format is published, so your work is never locked in.
Plans and credits
