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 डेटा एक्सेस
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.

Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Kodee and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
