A stateless message bus

Simple pub/sub and request/reply in one easy executable.

Up and running in seconds

Just one executable with no required complex config.

bicker v0.1.0 listening on :9500

Everything you need, nothing you don't

Bicker is a message bus with no opinions about your infrastructure.

Single Executable

Download one binary and you're done. Prefer containers? We provide a container image too.

Zero-Copy Protocol

Hand-rolled binary wire format. No serialization overhead, no external dependencies.

Pub/Sub + Request/Reply

Hierarchical path addressing with wildcards. Request/reply built into the protocol, not bolted on.

Stateless by Design

At-most-once delivery. No persistence, no locking, no coordination. Predictable performance.
