Soffi vs.
AI prototyping tools
Soffi is for you if
You don't have an easy way to host and share a prototype for feedback.
The thing you test with people is a dummy prototype, not the product.
Your product team is AI-native and still single-player.
You rebuild the same context every time: company, product, design.
What you can't do with AI prototyping tools
Why not just use Figma Make, Lovable, or Claude Design?
- Share it.One link. The real, running product, not a screenshot.
- Start from your product.Already wired to your product and company context. No re-uploading.
- Work on it together.Shared screen, cursors, comments, and video, on the thing itself.
- Edit an existing screen.Drag, resize, retype, swap variants, change tokens, on the real screens.
- Get a code review.Linted, typechecked, checked against your design system.
- Touch backend logic.Full monorepo, with logs and console errors in scope.
- Ship it.A PR you merge, not something a builder rebuilds.
- Let a stakeholder view and comment safely.Comment-only, authenticated, no setup or install.
The Landscape
“Why not just use Figma Make, Lovable, or Claude Design?”
| Soffi | Screenshots or mocks (Figma) | Vibe coding apps (Lovable, v0, Figma Make) | Handed to an agent (Claude Design) | |
|---|---|---|---|---|
| Who does this | Just us :) | Figma | Figma Make, Lovable, Claude Design, v0, Bolt | Figma Code Connect + MCP → Claude Code, Cursor |
| What you end up with | A shareable, dynamic prototype on live product | A static drawing of it | A separate app | Instructions for an agent |
| What you need to start | A browser | A design tool | Your design system, screenshots, code, and MCPs wired up by hand | The repo running locally, plus an agent subscription |
| Your real codebase | A sandbox | Through an engineer | ||
| Your product running, without local dev | We build and run it from your repo | There's no app, only a drawing | It runs, but it isn't your product | Someone has to run it locally |
| Design system grounding | Auto-extracted from your codebase, reflects production | A library someone maintains by hand | Whatever Code Connect exposes | |
| Multi-player | Build, comment, and record video together on the live product | But on a static screenshot or mock | ||
| Share it with a link and comment | One URL on the running product, with comment-only access | Comment on a link to a file, not the product | They can open an app, but not yours | Localhost only |
| Changes land in your codebase | A real source patch, as a PR | Rebuilt by hand | A model-written diff | |
| Where the current version lives | One shared environment | A design file | A vendor sandbox | Someone's laptop |
| Time to a real change in the product | Minutes | Weeks. Someone still has to build it | Days, and it gets rebuilt against your codebase | Fast, but needs rework and only for whoever can run the repo |

Coexist
Keep using it however you already do. Bring the files in as context.
Stay with your engineers. Same branch, same PR, everyone seeing the same thing.
Linear and Jira stay where work is tracked. Soffi can build directly from a ticket, and it's still where the work lives.
What we've heard
"We don't have one source of truth that multiple designers can collaborate on. We have three designers working on one release, and three different prototypes."
"I rip through 8 hours in Claude Design and burn 500 bucks, just to throw them in Figma, make tickets, and hand off to eng. If we could interact directly with PRs on our code, that would be a lot faster and easier."
"We wireframe in Figma, and we're using Figma's Connect to do all the mappings. But, it's still a dummy prototype. It doesn't feel like an actual product."
"Whenever we edit existing screens, the prototype starts from scratch. That's why current tools haven't worked. If anything, it adds another step and more confusion."
Common questions
Soffi runs your actual product, so there's no new file to keep in sync and no new place for work to live. Your code is already the source of truth. The problem is that your prototypes aren't. Bring the Figma files you already have, keep the tools your engineers already use, and everything leaves as a pull request in your repo.
No. Keep Figma for whatever you use it for today, and bring those files into Soffi as context. Soffi is for the product that already exists: designers and PMs get their work shipping as pull requests instead of handed off, and engineers get front-end work off their queue without giving up review.
No. Click an element and change it, or describe what you want. And if your designers already code, the point isn't capability. It's that nobody should need an IDE and a local setup to edit. Either way, you open real pull requests, and engineers still merge them.
Install your GitHub app and give us a few environment variables. We build the containers, auto-discover your services, seed a database, deploy a running instance, and read your architecture and design system. One engineer connects it once and everyone else is one click from the running product. Same-day on a modern stack, and we're white-glove through the beta.
We extract it from your codebase, so components, tokens, and variants are what's actually running in production. That's also why what you approve is what ships. There's no translation step in between.
Nothing merges without your review. Every change is a branch that becomes a PR in your normal pipeline, with your CI, your tests, and your approvers. We run lint and type-checks before the PR even exists, and you're working on seed data in an isolated environment, never production.
