## What it is
SteVe is an open-source OCPP server implementation in Java for managing EV charging stations, charge points, user data, and RFID card authentication. It supports OCPP 1.2 through 1.6J including Security Extensions and has been actively maintained since 2013.

## Use cases
- manage EV charging stations with an open-source OCPP backend
- self-host a charge point management system for OCPP 1.6 chargers
- authenticate drivers with RFID cards at charging points
- test and evaluate OCPP charge point implementations
- implement smart charging profiles and remote charger control
- run a CSMS for a small charge point operator network

## When to choose
- you need a free, self-hosted OCPP server supporting OCPP 1.2S through 1.6J with security extensions
- you want to manage charge points, users, and RFID tags without vendor lock-in
- you are a developer or researcher prototyping EV charging ideas on an open platform
- you operate a small-to-medium charging network and can manage your own deployment

## When to avoid
- you need OCPP 2.0.1 support, which is not yet available
- you want a managed SaaS with enterprise features like multi-site hierarchy, invoicing, and OCPI roaming - consider the commercial Powerfill offering instead
- you lack the ability to self-host and operate a Java web application
- you require formal OCPP certification for your own backend, since the certificate applies to Powerfill's build rather than SteVe itself
