RESTHeart turns a MongoDB database into a REST, GraphQL, WebSocket, and SSE API, with authentication, authorization, and real-time change streams already wired in.
Point it at a MongoDB instance and the API is there: no routes to write, no permission checks to hand-code, no pagination or filtering logic to duplicate across endpoints. Permissions and behavior are configured declaratively. Custom logic goes into plugins, written in Java, Kotlin, JavaScript, or TypeScript, only for what a data API cannot express.
curl "https://demo.restheart.org/messages?filter={\"from\":\"Bob\"}&pagesize=1"No route was written for /messages. It is a MongoDB collection, and the query parameters (filter, pagesize, sorting) map directly to MongoDB's query language.
- REST API: full CRUD, aggregations, filtering, sorting, pagination, generated from the database schema
- GraphQL: schema-driven mapping to MongoDB queries
- WebSocket: change streams exposed as real-time data sync
- SSE: Server-Sent Events for dashboards, IoT feeds, and event streams
- Authentication and Authorization: JWT, OAuth2, LDAP, MongoDB-based users, ACL rules defined as data, not code
- Plugin framework: custom services, interceptors, and initializers in Java, Kotlin, JavaScript, or TypeScript, for the logic a declarative API cannot cover
- Metrics and monitoring: a Prometheus-compatible endpoint plus a browser dashboard at
/metrics-ui, tracking request rates, latency percentiles, and HTTP status distribution - IoT / MQTT: ingest device telemetry directly into MongoDB (coming soon)
Distributed as a Docker image and a GraalVM native binary. Built on Java 25, Undertow, and virtual threads.
Fully managed, no installation required, and including Sophia, an MCP server and browser assistant that exposes RESTHeart's docs and plugin API to AI coding assistants such as Claude Code, Cursor, or VS Code:
