Design system assurance
The design system you approved is the one that ships.
FISYCO continuously verifies that the product your customers see still matches the system your organization approved — and turns every divergence into a controlled, reviewable change.
Connect Figma and your repositories. No migration. No rewrite. No silent writes.
Free during the public beta — no card required, and pricing lands before general availability.

The category
FISYCO is the assurance layer between the design system your organization approves and the product your customers actually receive.
Not a design tool and not a CI check. A layer that keeps the two sides equal and proves it.
The gap
Two copies of one system, and nobody owns the difference.
Design decides. Engineering re-implements. Between the two, the copies drift — a colour here, a component variant there. Nothing breaks loudly, so nothing gets prioritised, and the cost arrives later.
The drift is invisible until it is expensive
By the time drift becomes visible, you have already paid for it — in rework, inconsistent customer experience, delayed releases, or brand erosion.
Can you prove the product you ship still matches what you approved?
Design can’t. Engineering can’t. Leadership has no independent way to verify it.
Your customers don’t experience your design system. They experience what shipped.
Business impact
Drift compounds. So does the cost.
Rework
Teams repeatedly rebuild decisions that were already made.
Release risk
Small inconsistencies accumulate until fixing them becomes a project.
Brand integrity
Your customers experience the implementation — not the design you approved.
How it works
Nothing changes without accountability.
Every divergence between the approved system and production becomes a traceable, reviewable change — delivered through the workflow engineering already trusts.
Step 01
Connect without migration
GitHub, GitLab — including self-hosted — and Bitbucket. Read scope you choose, write only through pull requests.
Step 02
Establish the baseline
Components, tokens, icons and illustrations on the design side; the design system that already exists in your code on the other.
Step 03
See what matters
Each divergence carries a severity and a reach — how many places it actually touches — so the queue is ordered by consequence.
Step 04
Fix through existing controls
A webhook, a schedule, or a person starts a sync. The run leaves a pull request, and merged or closed, the result is recorded.

Control
Built to survive a security review.
FISYCO observes by default and changes code only through your existing approval process. Every action is attributable, reversible, and auditable.
No uncontrolled writes
Changes arrive as pull requests under a policy you set. Nothing lands on a protected branch without a reviewer.
Your infrastructure, your scope
Self-hosted GitLab, Bitbucket inside your perimeter, enterprise Figma. Access is granular and revocable.
A complete audit trail
Every sync, every divergence, every acknowledgment is recorded with who and when — available long after the release.
