Design in production.
Design and prototype in your own codebase. No coding required.
The team and I are really loving Dessn. I feel creative again.
Abigail Augustine
Product Design Lead, Wispr
Having tested close to 17 prototyping tools, Dessn understands the key: production code is the source of truth.
Janice Policinski
Product Design Leader, Greenlight Guru
This is not just better than v0. This is one of the best products I think I have ever used.
Sam Nesbitt
Cofounder, Autoplay
As a design engineer, even the latest frontier models struggle to help on UI work, until Dessn.
Moe Amaya
Design Engineer & Cofounder, Operate
Being able to explore ideas in the context of your production codebase is a cheat code for designers.

How it works
Dessn is the only product that allows you and your entire team to collaboratively design directly in production, without ever having to open up an IDE.
Connect your codebase in 1 click
Give Dessn read access to your repo. That’s it.
Your codebase becomes your design environment
Every prototype is a live branch of your codebase. No localhost, no MCP.
Design. Prototype. Build.
Create brand new flows, work on your components, or iterate on existing interfaces — directly in your real product, collaboratively.
Security & privacy
Dessn takes the security of your codebase seriously.
We are SOC2 Type II certified.
Codebase security
Each project runs inside its own isolated microVM and is not trained on.
Read-only by design
Dessn never writes, modifies, or pushes code back to your repo.
Scoped access only
Scoped access only. Grant access to specific repos, with permissions you can revoke anytime.
One source of truth for one product team

"We are blown away with the quality of what we're able to produce."
Director of Design
"Dessn was a godsend for us. Communicating really effectively internally with stakeholders and interacting with the experience in a prototype was a dramatic difference than static Figma mocks."
Senior Product Manager
"Was able to reuse 90% of the generated code!"

FAQs
Dessn is for product teams, of any size, who want to move faster.
Dessn brings non-devs into production to design and prototype. We finally exist in the same world- and the one that matters most. This removes a lot of the pains in the handoff that currently exists between very different environments, enabling teams to move a lot faster and produce higher quality work.
Implementation is as simple as it seems. You connect your repo and we do the rest to extract your components and create a design environment that is accessible to anyone in your team. We're aiming for 24hr turnaround on environments being ready for you after you connect.
No. Dessn's AI handles all the technical complexity, letting you focus on design decisions.
We support React webapps. No setup or selection limitation on CSS or component libraries. Don't worry about your messy code - we'll handle it.
