Works with your setup

Fragments fits the AI assistants, editors, off-the-shelf component libraries, and custom in-house React systems your team already ships with. Keep your stack — add the governance layer that keeps it consistent.

PR Enforcement

Every pull request is automatically checked against your design system rules. Non-compliant changes get flagged before they merge — no manual review, no drift slipping through.

Primitive Consolidation

Fragments scans your codebase for repeated raw elements and recommends the primitives you're missing. 47 raw <button> elements across 12 files? Get a single Button primitive with the right variants — and an autofix PR that updates every callsite.

Figma Token Sync

Design tokens drift from Figma within weeks. Fragments detects mismatches instantly and surfaces them before they compound — so design and engineering stay in sync.
