Recursica
Better UX for the internal tools
your teams use every day.
30 years of UX knowledge codified to ensure AI agents design great UIs.
Recursica is an open-source design and development system built for modern product teams. Work side-by-side with smart AI agents created by Border UX based on our knowledge and expertise. We want to empower product owners and back-end engineers to design better products, and to make designers more efficient and effective.
Free to use on your own, or set up and customized in 90 days by Border UX.
Stop making your engineers do UX.
Internal tools suffer from slow feature delivery, inconsistent user interfaces, high maintenance debt, and frustrated users. Generic AI coding tools lack your team's context, architectural rules, and design standards. It would be nice to have designers involved, but they are too busy and too few.
Stop skipping user research.
Real user research keeps getting cut because analysis can take weeks. Our research agents turn interview transcripts into themes, findings, and personas in hours. And every finding is fully traceable back to the original interview quotes.
Stop drawing static screens in Figma.
Managing variables in Figma is a full-time job. And a nightmare. The larger your design system, the more time designers spend editing variables instead of solving problems. The tools have gotten in the way. Recursica enables designers to build coded prototypes of their ideas.
Stop coding inconsistent experiences.
Your team is building more internal apps than ever with AI tools like Claude and Cursor. The catch? Every interface looks and works differently. Reinvented components and mismatched colors are creating a disjointed user experience. Recursica is your common component repo ready to go.
Human + AI UX design,
all via chat.
We use an open-source Slack-like app called Buzz to collaborate with our agents (but the agents can be deployed in any environment). The agents use custom skills built using Anthropic's standard, portable to any platform, built and maintained by Border UX.
Support keeps getting tickets about editing orders one at a time. Can we add bulk editing to the orders screen?

Is your design system agent-ready?
Agents are only as good as the system they build against. If your tokens live in three places and your rules live in people's heads, an agent will guess, and it will guess differently every time.
Take the quizWe wrote down everything we know.
The internet is full of opinions. Our knowledge codifies Border UX's judgment: rules, patterns, and the psychology beneath them, written as skills the agents consult on every decision. It's plain markdown in your repo. Read it, edit it, extend it with your own research.
Components
One skill per component: every variant, every state, with accessibility built in.
Design rules
Border UX's opinions written down as rules: when a button beats a link, why tables never scroll sideways, what a dashboard is allowed to show.
Psychology references
The cognitive science basis underpinning the rules, with citations for where a limit came from and where it stops applying.
Design great experiences with Border UX's knowledge via a team of agents.
Agents use our knowledge to do research and design UIs: each one specialized, collaborating with each other and with people. Orchestrators delegate to focused sub-agents, reviewers run their own checkers, and specialists go deep on one job.
Re-theme everything, light and dark mode included.
Stop updating hundreds of components one variable at a time. Your colors, type, spacing, and elevation live as tokens in Theme Forge, and one export restyles every screen at once. Light and dark mode, accessibility contrasts are checked as you style, and managing various brands and app styles (e.g. native mobile or web app) is a snap.

/ monthExport to anywhere.
Export the whole theme as standard DTCG json, scoped and unscoped css, or push it straight to GitHub or GitLab. Nothing is locked in a plugin or a design tool.
A push opens a branch with the token files committed, and CI builds Storybook from it, so the designer reviews the real coded components in the new theme before anything merges. That entire loop happens without the designer writing a line of code. A developer reviews the pull request like any other change and merges it.
Export theme
Now our designers can build pages faster and push changes quickly with less custom coding. What a difference.
Agents and people collaborating in every phase of design and dev.
