Direct answer
Keep Figma for collaboration and shadcn for component source. Add Better Design as the agent guidance and review layer, starting with one flow.
Give each tool one job
| Layer | Keep using it for | Avoid using it for |
|---|---|---|
| Figma | Exploration, critique, prototypes, and shared visual intent | The only record of production behavior or token values |
| shadcn/ui | Editable React component source and registry distribution | Choosing a complete product-specific visual direction |
| Better Design | Design-system choice, agent guidance, principles, and review rules | Replacing product judgment or repository architecture |
| Repository | Production tokens, components, behavior, tests, and history | Unreviewed one-off styles that bypass the system |
Adopt it in four steps
- Choose one contained flow such as onboarding, settings, or a form.
- Preserve the current components and extract the semantic tokens already used in production.
- Give the coding agent those constraints, then implement the flow with the existing shadcn-compatible source.
- Review the rendered states and promote only repeated decisions back into the shared system.
What should stay unchanged
- Existing business logic, routes, data contracts, and analytics.
- Components that already express the intended behavior and visual language.
- Figma files the team uses for exploration, critique, and stakeholder review.
- The team's release, code review, accessibility, and visual QA gates.
When not to add another layer
If the team already has documented tokens, complete components, agent-readable usage rules, and a dependable rendered-review process, keep that system. Better Design is useful when one of those pieces is missing, not because every React project needs another tool.
Progressive adoption should reduce uncertainty in a real flow before it expands. If it creates parallel tokens or duplicate components, stop and reconcile the source of truth first.
Questions
Must a team migrate away from Figma?
No. Keep Figma where it helps people explore and communicate. The important change is giving the coding agent a versioned implementation contract in tokens, components, and interaction rules.
Must existing shadcn components be replaced?
No. Preserve components that fit the product. Add or adapt source only where the existing system cannot express the required behavior or visual direction.
What is the safest first Better Design project?
Choose one reversible, bounded flow with visible quality problems and clear acceptance criteria. Avoid a full-product migration as the first test.
