Zeplin API
Zeplin ships a public REST API with an open-source OpenAPI spec and an official JavaScript SDK. Personal access tokens are self-serve from the profile Developer tab; public OAuth apps need manual registration. Webhooks are first-class, and the documented limit is 200 requests/min per user.
Frequently asked questions
Zeplin scores A on Supergood's API Report Card. Zeplin ships a public REST API with an open-source OpenAPI spec and an official JavaScript SDK. Personal access tokens are self-serve from the profile Developer tab; public OAuth apps need manual registration. Webhooks are first-class, and the documented limit is 200 requests/min per user.
Zeplin has a workable official integration path. Most engineering teams can build against it directly. Open API: self-serve, documented, with SDKs
Zeplin is a dedicated design delivery platform that sits between design tools (Figma, Sketch, Adobe XD) and the engineers who implement the resulting UI. Per CEO Pelin Kenez, 'design delivery is a phase of its own.
Vertical: misc (horizontal designer/developer tooling, not in any of Supergood's 23 named verticals). Designer-to-developer handoff: designer publishes a finalized version of a screen from Figma/Sketch/XD into a Zeplin project; developer opens the screen and copies spec values (px/dp/pt, colors, type tokens), exports assets at multiple resolutions, and grabs auto-generated code snippets (CSS, iOS Swift, Android XML/Compose, React/RN)..
Medium-high within the design-handoff niche, medium overall in the broader design-tools market. Zeplin reports 2M+ users and 200K+ companies.
Design artifacts: Finalized screens, screen versions and commit messages, sections, user-flow connectors, annotations/notes, components, styleguides, design tokens (colors, type, spacing)..
Founded 2014 in Istanbul; HQ now in San Francisco with continued Istanbul presence.
Rate limit of 200 req/min per user is restrictive for large enterprise automations (e.g., bulk asset sync across thousands of screens). Some resources are read-only, customers cannot fully CRUD all object types (e.g., create projects/screens programmatically), forcing manual setup in the UI. Full sourced list under Sources below.
Common alternatives include Figma (Dev Mode), Adobe XD (Share for Review/Dev), InVision (DSM/Inspect), Sympli, Avocode (Sketch/Figma handoff), Anima. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Zeplin scores GOOD on MCP availability. Zeplin publishes an official MCP server that exposes screen and component specs, annotations, and design tokens to AI agents. It lives in the vendor's GitHub org with full install and configuration docs and shows active development in 2026.
Yes. Zeplin publishes an official MCP server, so MCP clients like Claude, Cursor, and Codex can connect to it directly. Setup instructions are in the vendor's documentation.
