Koryvant vs Subframe
Subframe is a design tool built to produce clean front-end UI. Koryvant works one step wider — it generates the complete product surface, every screen and state, both themes, as a decided design you hand to any stack.
Is Koryvant a good Subframe alternative?
Yes — for designing the whole product surface rather than assembling UI components. Subframe is a design tool that produces clean front-end code component by component; Koryvant generates every screen and state of the whole product, with framework-neutral handoff.
Subframe is a design tool aimed at building polished UI and components that translate cleanly into front-end code, working component by component.
Koryvant generates the whole product rather than individual components: the complete screen inventory in every state, in light and dark, under a bespoke design language, plus stack-agnostic handoff specs that are not tied to one framework. It hands off a decided design, not a running application.
Koryvant is the design-complete blueprint layer, not a full-app builder. There is no backend, no database, and no running full-stack app.
Koryvant vs Subframe, point by point
| Where they differ | Subframe | Koryvant |
|---|---|---|
| What it produces | Polished UI components that export to clean React and Tailwind code. | A clickable HTML prototype of the whole product plus stack-agnostic handoff specs — a safe static artifact. |
| Scope | Component by component. | Every screen a user reaches, in every state. |
| Output | Front-end code in one stack. | A safe static artifact, not code in one framework. |
| Handoff | Tied to React and Tailwind. | Framework-neutral specs buildable on any stack. |
| Pricing model | Subscription. | Free to generate, preview, and iterate; a one-time payment unlocks a project. No subscription, no credits. |
Questions
- Is Koryvant a Subframe alternative?
- For designing the whole product surface rather than assembling UI components, yes. Koryvant generates every screen and state in both themes as a clickable prototype with handoff specs.
- What does "complete product surface" mean?
- Every screen a user would reach, drawn in every state — empty, loading, populated, error, and edge — across both themes, not a set of individual components.
- Does Koryvant lock me into one framework?
- No. The handoff specs are stack-agnostic, so engineering can build on any framework it prefers rather than starting from a decision baked into generated code.
- How does pricing compare?
- Koryvant is free to generate, preview, and iterate. Unlocking a project to edit, deploy, and download is a one-time payment per project — no subscription and no credits. See the pricing page for the current price.
