Everything you need in one system

A single, consistent API for all your messaging patterns. fitz provides kv, streams, queues, rpc, notices, and more through one unified platform.

Built for Modern Architectures

fitz is built for modern architectures - from microservices to serverless to embedded edge systems. It's transport-agnostic (WebSocket and TCP today, QUIC later), storage-pluggable (local LSM, S3, Azure, GCP, OCI), and tenant-aware with JWT-based security and scoped routing.

Developer-First Design

Developers get a single, consistent API for everything from ephemeral notifications to durable event streams. Clean, idiomatic SDKs that fit your dev language of choice. Run fitz in a local containerized environment for dev and cloud-native runtimes for prod. fitz simplifies messaging, reduces operational complexity, and is designed to scale with your systems.

More Than a Broker

fitz isn't just a broker; it's a unified message fabric built for the cloud, connecting every mode of communication across your systems. Whether you're vibe-coding a new idea or extending a production monolith, fitz delivers one consistent, cloud-native layer for everything messaging should be: unified, fast, and complete.
