Leading#3 in Open sourcehigh confidence
Code-first background jobs and AI-agent workflows (~15.7k★) in TypeScript — durable, long-running tasks for developers.Our read
Why it ranks #3
About 15.7k GitHub stars, an active Discord, and a maintained Apache-2.0 repository support its position as a leading code-first workflow runtime for TypeScript AI tasks.Here is the catch
code-first design excludes non-technical workflow builders
production deployments still require careful concurrency and cost planning
smaller general-purpose integration ecosystem than n8n or Zapier
Does this well
durable execution is a strong fit for long AI jobs
excellent TypeScript developer experience and observability
supports retries, queues, streaming, and human approval flows
Pricing
