Apache Pulsar

Cloud-native distributed messaging and streaming platform

About Apache Pulsar

A cloud-native messaging and streaming platform with multi-tenancy, geo-replication and tiered storage, separating serving from storage so brokers and bookkeepers can scale independently for large event workloads. It is free and open source, so teams can self-host it, inspect the code and adapt it to their own infrastructure without licence fees or vendor lock-in. Typical users run it alongside existing workflows to cut manual effort, improve visibility and keep full control over data, configuration and upgrades over time.
