Durable execution
built for AI agents

Persistent memory, multi-agent coordination, crash-safe workflows, and real-time observability. One Rust binary, zero dependencies.

Think Temporal + Redis + Datadog, purpose-built for agents.

Be first to know when we launch. No spam, ever.

The problem

  • Agents lose all memory between sessions
  • Crashed workflows restart from zero, wasting time and money
  • Multi-agent teams can't share or coordinate knowledge
  • Existing tools solve memory OR execution, never both
  • Scaling past one machine means rearchitecting everything

How Reverb solves it

  • VinylGraph memory with 146 MCP tools. Your agents remember everything.
  • EchoMulti-agent memory coordination. Agents share, deduplicate, and reach consensus.
  • HarmonyDurable execution with provider-aware retry. Crash mid-workflow, resume exactly where you left off.
  • CloudSame code, distributed scale. Coordinate agents across servers with federated search and enterprise compliance.

All three ship together in a single Rust binary with zero dependencies.

The Reverb Platform

Vinyl provides memory. Echo coordinates it across agents. Harmony ships both in a single binary with durable execution. Cloud scales it all.

How It All Connects

Bureau enhances your CLI agents. Reverb gives them memory and reliability.

Why Reverb?

Built different from existing solutions

Zero Infrastructure

No Docker, no Kubernetes, no external databases. Ship a single binary.

AI-Native

Designed for agents from day one. Not a general workflow engine with agent bolted on.

Open Core Model

Vinyl and Bureau are open-source. Echo, Harmony, and Cloud add paid intelligence layers.

Rust Performance

Fast, memory-safe, single binary. No JVM warmup, no GC pauses.

Pricing

Simple, transparent pricing that scales with your team.
