Best for real-time video models through an API
Decart is an AI lab with real-time video models like Lucy for live editing and Oasis for interactive worlds, sold through an API with no subscription. Realtime editing is $0.02 a second, or $0.04 in fast mode, and new accounts get free credits to try. It's a product for developers, not a finished video app.
Who Decart is for
- Fits if you're a developer adding live video effects to an app
- Makes sense if you'd rather pay per second than take a subscription
Who Decart is not for
- Not for you if you want a video app, as using it takes code
- Watch out: realtime fast mode is $0.04 a second, double the base rate
- Watch out: Oasis 3 is a preview, and enterprise pricing is by contacting them
- Skip it if you need a free allowance you can count on, as the credit amount isn't stated
Why Decart gets a 2.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for moneyPay as you go with no plan and no minimum: $0.02 a second for realtime Lucy 2.6, $0.04 for video editing. There's no monthly figure to set against the category, so it sits in the middle.
- CFree plan and trialNew accounts get free credits to test the API. The amount isn't stated, and the page doesn't say whether a card is needed.
- CFeaturesRealtime video editing, virtual try-on, video and image editing and the Oasis world model, which is still a preview. Each is an API model, not a ready-made tool.
- DEase of useNo rating on record, and using it means writing code against an SDK.
- BPlatforms and integrationsWeb docs, SDKs for JavaScript, Python, Swift and Android, plus Vercel AI SDK, LangChain.js and TanStack AI hooks.

Keep Decart, or make your own?
Keep it
To replace Decart you would be making a video model, which you can rent by the second but not make. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 106 of the 168 other AI image and video generators grade higher.
What you could not
- A video model, which you can rent by the second but not make.
- An image model, which you can rent by the picture but not make.
- It plugs into other products, Vercel AI SDK, LangChain.js and TanStack AI among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Decart’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
