Terrazzo
Modern alternative to Style Dictionary. MIT CLI (427 stars, ex-Cobalt UI) that transforms DTCG JSON v2025.10 into CSS, Sass, JS/TS, Swift, Tailwind. Full DTCG v2025.10 + resolvers (native modes). v2.1.0 released April 25 2026 (latest publish in research window).
Strengths
- Full DTCG v2025.10 today, no need to wait for a v6 (vs Style Dictionary)
- Native modes resolvers (light/dark, brand, theme, device), combinatorics on demand
- Integrated Tailwind v4 plugin, direct tokens → @theme pipeline
- CSS / Sass / JS / TS / Swift / Tailwind outputs, covers web + iOS + multi-stack
Limitations
- Ecosystem still young, fewer third-party plugins than Style Dictionary
- No native Android (XML) output, for Android, stay on Style Dictionary
- No documented native MCP integration, no direct AI bridge
Best for
- New web + iOS project on strict DTCG v2025.10 with Tailwind v4 + OKLCH
- Multi-brand / multi-theme DS needing native resolvers without hack
