Trigger.dev
Trigger.dev is an open-source platform for building AI agents and TypeScript workflows through web, API, or self-hosted deployment. Its managed tasks have no timeout, and the pricing FAQ says they can run as long as needed. Agent workflows support durable chat, tool calls, streamed responses, and human approval gates that pause and resume runs. Reliability features include cron schedules, retries, checkpointing, queues, concurrency controls, and task versioning. Run pages show live traces, logs, and debugging details; LLM observability records model, provider, token, cost, and latency information. Tasks can use Python scripts and libraries, while build extensions add dependencies, system packages, browser tools, and FFmpeg. Integrations include GitHub and Vercel, with compatibility shown for Next.js, AWS, Google Cloud, Azure, Netlify, Cloudflare, and SvelteKit. Free is free; Hobby costs $10 a month, Pro $50 a month, and Enterprise has custom pricing. All plans limit API requests to 1,500 per minute, with higher paid limits available by request.
