Trigger.dev is an open source platform and SDK which allows you to create long-running background jobs. Write normal async code, deploy, and never hit a timeout.
22
+
Trigger.dev is the open-source platform for building AI workflows in TypeScript. Long-running tasks with retries, queues, observability, and elastic scaling.
23
+
24
+
## The platform designed for building AI agents
25
+
26
+
Build [AI agents](https://trigger.dev/product/ai-agents) using all the frameworks, services and LLMs you're used to, deploy them to Trigger.dev and get durable, long-running tasks with retries, queues, observability, and elastic scaling out of the box.
27
+
28
+
-**Long-running without timeouts**: Execute your tasks with absolutely no timeouts, unlike AWS Lambda, Vercel, and other serverless platforms.
29
+
30
+
-**Durability, retries & queues**: Build rock solid agents and AI applications using our durable tasks, retries, queues and idempotency.
