# Client libraries support matrix for etcd

As etcd features support is really uneven between client libraries, a compatibility matrix can be important.

## v2 clients

The v2 API has a lot of features, we will categorize them in a few categories:
- **Language**: The language in which the client library was written.
- **HTTPS Auth**: Support for SSL-certificate based authentication
- **Reconnect**: If the client is able to reconnect automatically to another server if one fails.
- **Mod/Lock**: Support for the locking module
- **Mod/Leader**: Support for the leader election module
- **GET,PUT,POST,DEL Features**: Support for all the modifiers when calling the etcd server with said HTTP method.

### Supported features matrix

**Legend**
**F**: Full support **G**: Good support **B**: Basic support
**Y**: Feature supported  **-**: Feature not supported

Sorted alphabetically on language/name
