Runway builds an AI app from a description, no code

Runway has launched App Studio — a mode in which the user describes the tool they need in plain text, and the platform writes the code, tests it and deploys a finished app. Coding, API keys and hosting are taken out of this scheme: the app is connected right away to Runway's image, video and audio models, and to the account's Brand Kits, Workflows, assets and references. In the platform's changelog, App Studio is dated October 23, 2026.

What changes first of all is who on the team gets as far as generating. Until now the work was built around one-off requests: a specialist picked the model, the order of steps and the references from scratch every time, and the knowledge stayed in someone else's prompts and settings. App Studio captures that whole chain — the prompt, the sequence of models, the brand settings — and hands colleagues an interface where only the necessary input fields remain. Runway itself describes the difference this way: Agent is meant for one-off generation, App Studio packages the prompt, the model chain and the brand settings into a tool you can run again and again.

An app is assembled in three steps and edited with ordinary phrases

The build scenario is split into describing, refining and handing out. Edits are made in the same conversational language, every change can be previewed before publishing and rolled back to an earlier version, and the app's code remains open to inspection. A finished Agent session or an assembled Workflow is turned into an app by the platform in one click, locking in the prompt, the model chain and the settings — only the parameters the operator needs are exposed. If you later change the Brand Kit, the references or the Workflow itself, the next generations will pick up the edits.

What Runway showed in its first apps

• Character Swap — replaces the performer in an already shot clip: you upload a video and a new character as an image or a description, and the scene is played out again with them. The product page specifies that the app builds the keyframe from a depth map and uses the Seedance 2.5 model.
• AutoComp — swaps the product in finished material while preserving packaging and labels, so one clip can be rolled out across an entire SKU line.
• Product Portfolio — expands a single product photo into finished product visuals for a launch, a catalog or a store page.
• 3D Camera Control — sets camera position and movement in three-dimensional space for previz, VFX and animation.
• Precise Edit — retouches only the areas of an image the user has marked up; the rest of the frame stays untouched.
• Runway Pro — a template from which a studio assembles its own version of Runway for its own pipeline; according to the company, enterprise clients ask for this tool more often than any other.

Listed separately in the catalog are Product Photos, Style Out, Remove from Video, Reshoot Product, Upscale Video, Add Dialogue, Change Image Style, Add Performance, Change Backdrop, Change Time of Day and Relight Scene. The former Runway Apps moved into App Studio on their own: they can be used as before or rebuilt into your own version.

Partners built dozens of apps before the public launch

Before access opened, App Studio was road-tested by early access partners, and their examples explain the intent better than any feature description. The architecture firm KPF built an app that brings project renders to life: the designer marks on a static image what should move, draws a camera path and gets a video.

App Studio lets us build our own AI tools around how our teams work, so that every designer in the studio can use them, not just a few specialists, — Andy Cristoforo, associate principal at KPF.

A film studio made a tool that builds a continuous camera flythrough from a single photo of a location, and a second one for translating a trailer's on-screen titles while preserving fonts, effects and layout. A production company generates clean backdrops that match the camera movement on green screen, frame by frame. A game studio keeps characters identical from shot to shot and regenerates the whole set when the design changes. An ad agency assembles scenes by country, region and occasion and checks them against the brand's cultural guidelines. A technology company makes instrumental albums with cover art, and an accounting firm pulls a list of products, brands and models out of technical specifications with page references and exports it to a spreadsheet.

These cases have one thing in common: they are all about replication. A version of a clip for every market, a frame for every SKU, a character that must not drift between shots — tasks where the specialist spends time not on the solution but on repeating it. That is exactly the work Runway proposes to package into an app and hand over to the people who used to queue up for the specialist.

You'll pay with the same credits

App Studio is included in every paid plan at no extra charge and with no separate purchase. Building, running and hosting an app are debited from the same credit balance as ordinary generations, and each app shows its own spend. On the free plan you can use built-in and shared apps, but creating your own requires a paid plan.

An app stays private until the author opens access. The Team and Enterprise plans let you hand it out to specific colleagues, to a project or to the whole workspace, and on any paid plan you can publish a link externally: the guest sees a customizable preview, signs in with their own Runway account and spends their own credits, and the result stays theirs and is saved in their assets. The author decides where files generated in the app go — to personal storage, to a project or to the shared space. Enterprise administrators have been left the switches: turn off App Studio for the entire workspace, forbid public links, view spend per app. Models blocked in the admin panel remain unavailable inside apps too, and the user is shown the reason.

All year Runway has been gathering other people's models under its own roof

App Studio sits on top of what the company has been doing for the past few months. Walk through Runway's changelog for August through October and its own models are in the minority: Seedance 2.5 and Seedream 5.0, the Kling line, Ideogram, Wan 3.0, MiniMax Hailuo 3.0, ElevenLabs voices, Mirelo sound effects, BiRefNet background removal. In parallel came plugins for Premiere Pro, After Effects and DaVinci Resolve, connections to third-party chatbots and workflow control via MCP. Judging by that set, the platform is ceasing to be a showcase for a single model and becoming a place where models are stitched to one another.

Against this backdrop, value shifts from the quality of generation to the rigging around it. When a dozen competing video models are available to everyone on roughly the same terms, what starts to distinguish vendors is how quickly a studio turns its way of working into a repeatable tool and how cheaply it hands that tool to the team. Runway is betting precisely on this layer, and the bet has a weak spot: a tool assembled inside the platform stays with it — the app's code is available to view, but no way to take an app outside Runway is described in the announcement, and spend is tied to the same credit balance.

If the trend continues, similar builders will probably show up among the neighbors on the market, and a new applied role will emerge inside studios — a person who describes and maintains such apps for the team without being either a programmer or an artist. For specialists the practical takeaway is simpler: part of the routine now covered by a junior with access to generative models will probably turn into a form with three input fields.
