  We’ve just released EventSourcingDB 1.0 – a new database designed from scratch for event sourcing projects. It focuses on simplicity, consistency, and performance, while eliminating external dependencies like message brokers or coordination services.

  Key features include:

  – Append-only event storage with strict immutability and global ordering

  – Atomic writes across multiple streams with built-in concurrency control

  – CloudEvents-compliant HTTP API for writing, reading, and observing events

  – Live subscriptions with long polling, recursive stream support, and replay capabilities

  – Snapshots and versioned schemas for evolving data models

  – Secure by default: HTTPS enabled, API token protected, read-only fallback on license expiry

  – Minimal operational footprint: no brokers, no coordination layer, no external runtime

  – First-class observability: OpenTelemetry, Prometheus, and automation support

  – Runs anywhere: Linux, macOS, Windows; x86 and ARM; Docker or native binary

  EventSourcingDB is free for small projects (up to 25,000 events). A commercial license is required for larger projects.
