Runway launched App Studio on October 26, 2026, letting paid users describe and build custom creative apps inside its platform. The announcement says apps can generate images, video, and audio using a workspace’s Brand Kits, Workflows, and assets. Users can keep an app private, share it with a team or publish a link.
The launch adds a reusable interface around creative work that might otherwise depend on one person’s prompts and settings. That could help with recurring jobs, such as turning a product photo into several campaign formats. Whether the outputs satisfy a particular brand still needs evaluation.
Who can build, and who can run an app?
App Studio is included in paid plans. Free users can use built-in apps and apps shared with them, while building their own requires a paid plan. A public link is not anonymous access: visitors sign in with a Runway account and spend their own credits on generations. Team and Enterprise users also have workspace sharing controls.
The cost follows three different activities
Runway says building, running, and hosting apps draw from the existing credit balance. Public visitors pay for their own generations, while creators pay to build their app, generate with it themselve,s and keep it hosted. The plan comparison is a separate reference for the underlying subscription.
| Budget line | Question for the creator |
|---|---|
| Build and revise | How much credit does development consume before the app is useful? |
| Run generations | Who runs the app, and how many outputs do they need? |
| Keep it hosted | What ongoing usage appears while the app remains available? |
These distinctions matter for a shared internal tool. A simple interface can reduce repeated setup work while leaving generation and hosting costs in place. A team evaluating App Studio should track those costs separately so a successful prototype doesn’t become an unexplained recurring expense.
There is also a difference between locking down inputs and guaranteeing an output. A smaller interface can reduce accidental changes to settings, but it can’t ensure every generated product label, scene, or brand detail is correct. The review standard should come from the actual asset’s intended use.
