Storyblok API
Headless CMS with a visual block-based editor, dual APIs for content delivery (CDN-backed) and management, and component-based content modeling.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Headless CMS API. Preview token (public) + Management token (private). Management API has write access to all content — keep secret. Space-level token isolation.
⚡ Reliability
Best When
Content editors need a visual page-building experience while developers need API flexibility for headless delivery.
Avoid When
Your team is purely developer-focused with no content editor UX requirements, or you need very complex data relationships.
Use Cases
- • Content editors building pages with drag-and-drop blocks
- • Multi-language content delivery via CDN for frontend apps
- • Programmatic content creation and management for agents
- • A/B testing and personalization with content variants
- • Building preview environments with draft content
Not For
- • Developer-only workflows without content editor requirements
- • Very high write throughput applications (rate limits on management API)
- • Complex relational data models beyond nested block components
Interface
Authentication
Content Delivery API uses preview or public tokens (per space). Management API uses personal access tokens or OAuth app tokens. Tokens are space-scoped.
Pricing
Free tier is for individual developers. Team and collaboration features require paid plans.
Agent Metadata
Known Gotchas
- ⚠ Content model uses 'stories' and 'components' terminology which differs from other CMS providers
- ⚠ Draft and published versions are separate - agents must specify cv (cache version) parameter for fresh content
- ⚠ Management API has stricter rate limits than the CDN-backed delivery API
- ⚠ Component schema changes require republishing all stories using that component
- ⚠ Nested blocks have arbitrary depth - agents must recursively handle component trees
