Zero Code, Zero HTML, Solaris Redraws Your App at Every Click
All blog articles
No HTML, no CSS, not one line of JavaScript. Runway's new Solaris model generates the app you see, pixel by pixel, as a live video stream that reacts to your every move.
Yes, that sounds odd. Stay with me, because this may be the boldest interface idea of 2026 so far.
What happens when an operating system generates apps and websites as you use them?
Solaris, the app that exists only as pixels
Unveiled on August 31, Solaris is the first of what Runway calls its Interface World Models. Instead of code that a browser executes, the model synthesizes each interface frame in real time. Every click, drag, or typed command triggers the next image.
Under the hood, a language model decides what should happen next. The world model, built on Runway's Gen-4.5 video engine, then draws the result at 720p. The target sits under 500 milliseconds per frame, in line with the GWM-1 project Runway started in late 2025.
Why Solaris looks nothing like Lovable or Bolt
Vercel's v0, Lovable, and Bolt also turn prompts into apps. All of them, though, still write code as a middle step, then run it the classic way.
Solaris skips that translation: the screen is the software, full stop. Honestly, it feels like an operating system built out of lucid dreams, and I mean that as praise. The whole industry keeps prodding the interface layer, and Anthropic just gave Claude a built-in browser that handles the web for you.
What if the app stopped existing as a unit?
Runway's ambition reaches well past a demo. If an operating system can generate a useful interface on demand, the fixed app catalog loses its point. What you need simply shows up, shaped around you.
Agents stand to gain too. AI agents still fumble on unfamiliar websites, so a bottomless supply of generated interfaces would hand them an infinite practice ground.
Solaris remains a preview, not a product
Keep your expectations in check. Text rendering stays shaky, long sessions can drift, and screen readers find nothing to latch onto.
Runway frames this as research, with early access granted by request. In its internal study, 250 evaluators preferred Solaris over interfaces coded by Claude in 61 percent of instruction-following tests. No third party has verified those numbers yet.
What is Runway Solaris?
Solaris is a research model that generates interactive software interfaces frame by frame, like video, with no underlying code. It responds live to clicks, drags, and text input at 720p resolution.
Can you try Solaris today?
Not yet. Solaris is an early-access research preview: you can request access through a form on Runway's site, but no public release or API exists.
