Koryvant vs Proto.io
Proto.io builds high-fidelity, interactive prototypes screen by screen. Koryvant generates the whole product in one pass — every screen a user reaches, in every state, across both themes — from a prompt.
Is Koryvant a good Proto.io alternative?
Yes — for generating a complete, high-fidelity prototype of the whole product from a prompt rather than assembling and wiring screens by hand. Proto.io builds high-fidelity mobile prototypes screen by screen; Koryvant derives the whole product in one pass.
Proto.io is a web-based tool for building high-fidelity interactive prototypes, especially for mobile, where you assemble and wire screens by hand.
Koryvant generates the complete product from a description rather than building it screen by screen: every screen in every state, in light and dark, under a bespoke design language, plus stack-agnostic handoff specs. It hands off a decided design, not a manually assembled flow.
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 Proto.io, point by point
| Where they differ | Proto.io | Koryvant |
|---|---|---|
| What it produces | High-fidelity interactive prototypes, mobile-strong, built screen by screen. | A clickable HTML prototype of the whole product plus stack-agnostic handoff specs — a safe static artifact. |
| How it is made | Manual assembly and wiring. | Generated from a chat prompt. |
| Scope | The flow you build. | Every screen a user reaches, in every state. |
| Themes | Whatever you build. | Light and dark, on one token system. |
| Pricing model | Subscription. | Free to generate, preview, and iterate; a one-time payment unlocks a project. No subscription, no credits. |
Questions
- Is Koryvant a Proto.io alternative?
- For generating a complete, high-fidelity prototype of the whole product from a prompt, yes — every screen and state, both themes, with handoff specs.
- Is the prototype interactive?
- Yes. Screens link and states respond so you can click through the real flow, but it is the design surface, not a live app. Koryvant is the design-complete blueprint layer, not a full-app builder. There is no backend, no database, and no running full-stack app.
- 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.
