Deploy CitrineOS in one click installation.
Open-source OCPP 2.0.1 charging station management system for electric vehicle network operators.
What you can build with CitrineOS
CitrineOS is an LF Energy open-source charging station management system (CSMS) built around the OCPP 2.0.1 protocol, with backwards support for OCPP 1.6. The server routes WebSocket messages from EV chargers, persists transactions and configuration in PostgreSQL with PostGIS, and exposes REST and GraphQL APIs through a Hasura layer for operator integrations.
Self-hosting CitrineOS on your VPS keeps station telemetry, driver authorizations, and transaction history under your own control instead of a vendor cloud. The Hasura GraphQL console lets you query and manage charging station data directly in the browser, while OCPP WebSocket ports remain open for chargers to connect.
Key features of CitrineOS
OCPP 2.0.1 native
Implements the latest Open Charge Point Protocol with certified core and advanced security profiles, plus backwards compatibility for OCPP 1.6 stations.
GraphQL data console
Hasura auto-generates a typed GraphQL API and console over the CitrineOS schema, enabling real-time queries on sessions, meter values, and station status.
Modular message router
Decorator-driven module system routes OCPP messages through RabbitMQ, so authorization, transactions, and reporting modules scale independently of the WebSocket layer.
GraphQL data access
Hasura auto-generates a typed GraphQL API over the CitrineOS PostgreSQL schema, exposing real-time subscriptions for sessions, meter values, and station status.
S3-compatible storage
Built-in MinIO instance stores firmware images, station logs, and certificate bundles via the standard S3 API, ready to swap for AWS S3 or GCS later.
LF Energy governed
Vendor-neutral project hosted by the Linux Foundation Energy, with an Apache 2.0 license and a roadmap driven by EV charging network operators.
