24 alternatives to Hatchet – open-source, event-based workflow engine
Hey HN - over the past few months, I’ve been working on Hatchet, which is a workflow engine meant for event-driven applications. Workflows are triggered by user-defined events (along with schedules and cron jobs). It bundles a web UI for observability and has several integrations built out (Sentry, OpenTelemetry, Slack). It’s very similar to using an SQS + EventBridge + AWS Lambda stack, but uses worker pools to process functions instead of isolated function invocations. Some features that Hatchet offers: 1. Publish, react to, and query events using the Events API [1] 2. You can define…

Hello HN, we're Gabe and Alexander from Hatchet (https://hatchet.run), we're working on an open-source, distributed task queue. It's an alternative to tools like Celery for Python and BullMQ for Node.js, primarily focused on reliability and observability. It uses Postgres for the underlying queue. Why build another managed queue? We wanted to build something with the benefits of full transactional enqueueing - particularly for dependent, DAG-style execution - and felt strongly that Postgres solves for 99.9% of queueing use-cases better than most alternatives (Celery uses Redis or…

Hey HN - this is Alexander from Hatchet. We’re building an open-source platform for managing background tasks, using Postgres as the underlying database. Just over a year ago, we launched Hatchet as a distributed task queue built on top of Postgres with a 100% MIT license (https://news.ycombinator.com/item?id=39643136). The feedback and response we got from the HN community was overwhelming. In the first month after launching, we processed about 20k tasks on the platform — today, we’re processing over 20k tasks per minute (>1 billion per month). Scaling up this quickly was…

For the past few months we’ve been building Trigger.dev and can now share our beta with you: https://github.com/triggerdotdev/trigger.dev. Trigger.dev is an open source platform that makes it easy for developers to create event-driven background tasks directly in their code. You write workflows using our SDK, and can view all the runs in our web app. Why we built this: - We found current workflow / automation tools like Zapier and n8n are good for simple tasks, but not for more advanced use cases. - Dropping down into code in these tools is just not a great…

Hi HN! We’re Tony and Dan, the founders of Inngest - https://www.inngest.com. We’re an event-driven queueing system. Existing queueing solutions have pretty terrible UX. We solve this by making it simple for you to write delayed or background jobs by triggering step functions from JSON-based events. At a high level, Inngest does two things: - Ingest events from your systems via HTTP (pun intended) - Triggers serverless functions in response to specific events — async, either immediately or delayed. This allows you to build out async functions (eg. background jobs, handling…

Hi HN! I’m Tony, one of the co-founders of Inngest (https://inngest.com/) Inngest is an open-source durable workflow platform that works on any cloud. Durable workflows are stateful, long running step functions written in code, which automatically retry on failure. It abstracts everything about queues, event streams and state for you, letting you focus on code. Some examples of uses: managing stateful AI chained step functions; managing search/rag indexes and data pipelines; integrations and webhooks; billing and payment flows. Technical details: unlike other solutions,…

Hey HN, I am building an open source platform to make on-call better and less stressful for engineers. We are building a tool that can silence alerts and help with debugging and root cause analysis. We also want to automate tedious parts of being on-call (running runbooks manually, answering questions on Slack, dealing with Pagerduty). Here is a quick video of how it works: https://youtu.be/m_K9Dq1kZDw I hated being on-call for a couple of reasons: * Alert volume: The number of alerts kept increasing over time. It was hard to maintain existing alerts. This would lead to a lot…

Render▲318Hey HN, I'm Anurag, founder and CEO of Render, a cloud for application developers. We've just launched Render Workflows, a way to define durable tasks by decorating plain TypeScript or Python functions and running them on Render without operating queues, worker pools, retry logic, and state management. Code example below [1]. The use cases we have in mind include agent loops, ETL/data pipelines, billing flows, and other long-running jobs. The model is simple: mark an existing function as a Task, deploy the repo as a Workflow, then trigger runs from your application code or via our API.…

Opsflow cofounder here! We launched a bunch of things recently, some of them well received (Terragen, AWS Bootstrap). It's no secret that AWS is hard, and our mission is to make it simple. What HN crowd helped us realise is that the UI was still not simple enough. Rather confusing in fact. So in the last couple weeks we have radically simplified it based on your feedback. We have removed the unnecessarily complex concepts like Services and Environments - it's just Apps now. All options are now on the new Settings screen. Instead of Infrastructure and Software deployments there is now a…
