deepstream is an open source server inspired by the concepts behind financial trading technology. It allows clients and backend-services to sync data, send messages and make rpcs at very high speed and scale.
Deepstream can be run as an executable on Linux, Mac & Windows. You can connect and interact with the deepstream server via our client SDKs or via its HTTP API.
records are schema-less, persistent documents that can be manipulated and observed. Any change is synchronized with all connected clients and backend processes within milliseconds. Records can reference each other and can be arranged in lists to allow for the modelling of relational datastructures.
events allow for high-performance, many-to-many messaging. deepstream provides topic based routing from publisher to subscriber, data-serialisation and subscription listening.
remote procedure calls allow for secure and highly available request-response communication. deepstream handles load-balancing, failover, data-transport and message routing.
presence allows you to query deepstream for the status of logged-in users and subscribe to anyone logging in or out across the entire cluster.
listening enables you to monitor your client's subscriptions actively and only provide data when it's actually needed. This significantly reduces data-throughput and costs, especially across larger micro-service architectures.
deepstream's finegrained identity and permission system allows you to permission each connection and message going through your system. Easily accept or deny messages in realtime based on user roles, data or even cross references to existing records.
