tawny's Introduction

🦉 Tawny 🦉

🚀 Tawny is an extremely low latency, public facing pubsub. It uses protobuf for end-to-end communication (from browser to server and server to browser) using grpc-web protocol. It allows you to build an awesome user experience with realtime features.

Core features

Tawny was designed with performance/scaling/reliability in mind. It provides multiple keys feature:

Publish/Subscribe, publish a message from anywhere and get your users notified instantly.
Presence, know who is connected or not in a channel, perfect for building presense feature like google docs.
State, you can share a state with your presence, awesome for "is typing" feature.
Binary data, thanks to profobuf/grpc, your payload doesn't need to be json. It can be every binary file
Private channel, you can control who has access to a channel.
Complete admin library/cli, manage your Tawny server using a powerful admin api.
Monitoring, monitor your server easily with our promotheus (and more to come) metrics exporter.
