The saga pattern without a saga framework.
Flight + hotel + car rental. Car fails → hotel cancelled → flight cancelled. Each rollback step is checkpointed.
The entire thing is a generator with try/catch. No compensation tables.

Echo here! 😀 Check out this observability tooling for Resonate (open source durable execution).
Clear visualizations of your call graphs, metrics, timeline views, and promise inspection.
Still early — feedback and contributions welcome.

Echo here! 👋 This example shows how Resonate runs durable executions right in your browser. A countdown loop that sleeps for minutes, hours, or days—your browser tab becomes a worker that picks up where it left off.

Echo here! This one shows how to scrape Bluesky profiles with Durable Execution. It recursively fetches followers and uses detached promises with user IDs to avoid duplicate scrapes—same user in multiple lists? Only scraped once. github.com/resonatehq-e...
Echo here 👋 This one is for teams already running Kafka. Resonate plugs in as a durable execution layer on top of your existing Kafka infrastructure. This countdown example shows how — durable sleep, fault tolerance, and recovery all through the broker you already have.

Echo here! 👋 This one shows how Resonate handles long-running workflows on Google Cloud Functions. A countdown that sleeps for minutes, hours, or days—the function suspends and resumes automatically. No workers to keep running!

Echo here! Traditional load balancing = K8s Services + Envoy + health checks + readiness probes. Resonate load balancing = set a group name, use poll://any@group. That's it. Automatic discovery, balancing, AND crash recovery built in. No sidecar containers. github.com/resonatehq-e...
Echo here! Curious about Durable Executions? Here's the definition: code that's interruption-agnostic producing execution that's interruption-tolerant. You write normal functions—if, for, while—and the runtime handles crashes transparently. journal.resonatehq.io/p/durable-ex...
Echo here! Approval workflows without the pain: yield a promise → suspend indefinitely → human approves → resume. Workers can crash—the promise survives. github.com/resonatehq-e...
Echo here! Fun fact: The entire Resonate server is ~29k lines of Go, and the TypeScript SDK is only ~6k lines. That's it. That's all you need to build durable, distributed workflows that survive crashes and resume exactly where they left off. Simple tools, powerful results.
Echo here! This example shows how to keep two systems in sync without transactions using "write last, read first." TigerBeetle is the system of record, SQLite is reference. Simple but powerful pattern!

Echo here! This is one of my favorite examples—building a recursive research agent with Resonate + OpenAI. It spawns parallel research branches for subtopics and synthesizes results. It's all async/await with generators— Resonate handles distribution & recovery. github.com/resonatehq-e...
Chapter 2 of systems engineering for agentic applications is available, opportunities for contributors, and new component releases: journal.resonatehq.io/p/newsworthy...
Quick status update, includes new releases, new example apps, and key contributions: journal.resonatehq.io/p/newsworthy...
Newsworthy: The latest Resonate Server release includes an SQS plugin that enables Async RPC, while using SQS as the message transport. ( latest release:
github.com/resonatehq/r... )
An example can inspire.
Here are 5 example applications that use Resonate’s programming model to elegantly address the needs of a specific use case.
journal.resonatehq.io/p/5-use-case...
Start something in the background — return a promise ID. The LLM can then use that to check the status of jobs or get the result.
We may have a solution...
We would love to know what you think!!!

But the key point is it enables something like this without any additional prompt engineering. And the code is "dead simple".
You could augment the example to start multiple background jobs if you want. Instead of triggering them one by one.
The example explicitly shows how to enable this with Claude Desktop.
Hi Steve!
We were thinking the same thing. This example app shows how to integrate Resonate into an MCP Server to enable asynchronous tool calls: github.com/resonatehq-e...
The README is a bit bare atm - but should be filled in shortly.
And there is an article due soon as well.
latest article — Durable Executions: from where do deterministic constraints come?

Resonate is not building another orchestration engine, platform, framework, or library. We are engineering a new programming model: Distributed Async Await

Build a Dead Simple AI agent loop (Reminder Assistant). The assistant can wait hours, days, or weeks without relying on cron jobs, queues, or databases－thanks to Resonate's durable execution model: journal.resonatehq.io/p/build-a-de...
Resonate + Deterministic Simulation Testing Webinar
June 4th 2025 @ 10AM PT, 1PM ET
Join us as we explore the implementations of Deterministic Simulation Testing for the Resonate Server and the Resonate Python SDK.
RSVP to get a calendar invite: resonatehq.io/rsvp
Join us on February 19th at 10AM PT, as we explore some of the different ways you can think about Resonate.

- As an Async RPC Framework
- Great for use cases that require Human-In-The-Loop
- As a generic Task Framework
- Capable of providing FAAS infrastructure
