Devs deprioritize design polish in favour of bigger tickets.
Shipped product diverges from the Figma every release.
B2B SaaS Prototype to Production
Turn Figma into production code
Designs already done. We ship them as reviewed PRs into your repo.

Why designs
stall in handoff
ProblemImplication
Edge cases and empty states never make it into the prototype.
Production UI breaks the moment real data shows up.
Design systems live in Figma, not in code.
Every screen rebuilt from scratch. Inconsistencies pile up.
Animation and interaction details lost in handoff.
The product feels cheaper than the design promised.
Built in layers
System first, then build, then review.
Design system in code
Tokens, primitives, and components extracted from your Figma library. The same values on both sides.
Screens built on the system
Every screen implemented on the coded system. Spacing, type, color, and motion match the Figma because they come from the same source.
Pixel-perfect, shipped fast
Agents build against the coded system at speed. Seniors review every PR against the design source. Accurate without being slow.
Working with Donux enabled us to iterate much faster, and as a result, we increased the adoption of a key product feature from 17% to 66%.

From Figma to production in 3 steps
From design source to merged PR, without handoff drift.
Share the Figma
Share the design file and your repo. We extract tokens and build a spec.
Agents build, seniors review
Managed agents implement every screen against the coded system. Senior designers and developers review pixel accuracy and architecture before anything reaches your branch.
Preview, approve, ship
Book a Discovery CallClick through the working result side-by-side with the Figma. Approve and the PR merges to your branch. Pay only for code that ships.
What you get
Everything you need to solve the design-to-code handoff problem.
Pixel-accurate UI implementation against your Figma.
Coded design system with tokens, primitives, and components.
All edge states handled. Empty, loading, error, success.
Senior human review on every change before it reaches your branch.
Pay-as-you-ship pricing.
Every change lands in your repo. You own the code.
Before you start.
Who is this for?
B2B SaaS teams with a Figma library or detailed prototypes ready to ship. Founders and product leads who want what they designed to actually reach users.
Do we need a finished design system?
No. If you have one, we follow it. If you don't, we extract tokens and primitives from your Figma and codify them. That becomes the system we build on.
What about edge cases the designer didn't draw?
They surface in the spec phase, before any code is written. Empty states, loading, errors, permissions, and copy gaps get mapped out first.
How is this different from vibe-coding with Cursor or v0?
Vibe-coding generates code from a screenshot with no design system, no spec, and no review. We extract your tokens, build against the coded system, and senior designers review every PR against the design source before anything reaches your branch.
How is this different from a traditional agency?
Agencies bill hours whether or not the work ships. We bill only for code that lands in your repo. If a change doesn't make it through review, you don't pay for it.
Who owns the code?
You do. The code lives in your repo from the moment it ships. No lock-in, no licensing strings.
Can you also handle new designs from scratch?
Yes. Pair this with our Product Design service. Senior designers craft the flows, then we implement them.
What if we already have engineers?
We plug in alongside your team.
