Product demosthat film themselves.

You describe the demo. Opsis films it.
- 01
Write the actions
Go to the page, click New project, type a name, press Enter, share it. Each one is a node. No code, no screen recorder.
- 02
Opsis records a real take
A real browser performs every action in one clean take. No retakes, no stumbles, no stray notifications.
- 03
It directs the shot
The camera moves in on each action, the cursor glides between them and the app sits in a clean window on a backdrop.
- 04
You get the finished film
Titles, music and transitions go on top, and one export writes every shape you asked for.
The product changed. The demo kept up.
A recorded demo goes stale the day the interface ships. An Opsis demo is a project, not a recording: press Run and it performs the same actions on the new design and rebuilds every video.
The app under the demo
Recorded on last month's design.
The same take, directed.
Drag across. On the left, what the browser recorded. On the right, what Opsis made of it: a camera that follows every click, a cursor that glides, a window frame and a backdrop.
Everything else a product film needs.
More than a hundred motion graphics, 3D devices, 25 transitions, music and sound effects, captions and terminal takes. Each one is a node in the same project. Every tile here is drawn live on this page.
Terminal takes
Real commands in a real shell, in any colour theme.
Tall cuts and captions
Captions timed from your script, word by word.
Animated text
A different way in for every line.
Transitions
25 of them, and every cut can have its own.
3D devices
Put the take on a laptop, monitor or phone that turns to face the camera.
Charts and numbers
Bars, tickers and timelines that move.
Keys on screen
Every key and shortcut, shown as it's pressed.
One project. Every shape.
One export writes all four. The tall, square and portrait cuts keep the whole window, move in closer on the action and keep captions clear of the edges.
Wide 16:9Sites, docs and talks
Tall 9:16Stories and short video
Square 1:1Feeds and posts
Portrait 4:5Portrait feeds
On your machine, on your terms.
- 01
Nothing leaves your computer.
Recording, editing and export all run locally. Opsis goes online only when you press a button that says so.
- 02
Free software, for good.
Opsis is open source under the GPL. Your films are yours: no watermark, no account, no licence to buy.
- 03
Built for agents too.
Switch on the local API and scripts or AI agents on your computer can read, change and run the open project. Every edit they make is one undo step.
Your next demo is one run away.
