Trigger.dev · The durable-execution layer that agent builders reach for first because it is just TypeScript — the clearest test of whether "make the agent loop survive a restart" becomes a product category or a framework feature.

Long-running background work written as plain TypeScript. You write a function, they run it on their infrastructure with no timeout — so an agent loop that thinks for twenty minutes, a nightly job, or a fan-out over ten thousand items all survive restarts, retries and deploys. The product's own centre of gravity has moved to AI agents: a chat agent that gets a real machine per conversation, versioned prompts defined in code, tracing over agent sessions. Apache-2.0 and self-hostable, with a hosted cloud at cloud.trigger.dev.
