What Trigger.dev does

Trigger.dev is an open source platform where developers write long-running tasks and AI agents in TypeScript and run them on managed infrastructure. Tasks are plain code, so there are no platform timeouts, and the system supports retries, queues, concurrency rules and durable cron schedules. For AI work, it offers durable chat agents that resume after refreshes, redeploys and crashes, human approval steps, and LLM observability that records model, tokens and cost for each call. Realtime features let you show run status in your app and stream LLM output to users. Build extensions let you add system packages, run Python scripts, use FFmpeg or browsers. The code is licensed Apache 2.0, and the vendor provides a self-hosting guide.

Pricing on the cloud service is freemium. The Free plan costs $0 per month and includes $5 per month of credits, 20 concurrent runs and 5 team members. Hobby costs $10 per month with $10 of credits and 50 concurrent runs. Enterprise pricing is custom. Usage is billed by machine compute time and by a per-run invocation cost of $0.25 per 10,000 runs. Time spent waiting in checkpointed waits is described as not counting toward compute usage. A HIPAA BAA is a $500 per month add-on. All plans share a limit of 1,500 API requests per minute.

Pros and cons

Pros

  • Free plan at $0 per month with no credit card required
  • Open source under Apache 2.0 with a self-hosting guide
  • Tasks have no platform timeouts and survive crashes via durable execution
  • LLM observability shows model, tokens and cost per call
  • Usage-based billing: you are charged only while tasks execute

Cons

  • Aimed at TypeScript developers; tasks are written in code
  • Free plan limited to 20 concurrent runs and 1 day log retention
  • Free plan requires an upgrade once the included $5 of credits is used
  • Pro seats beyond 25 cost $20 per month per seat, and extra usage is billed on top
  • HIPAA BAA costs an extra $500 per month

Our take

Trigger.dev fits TypeScript developers who need background jobs or AI agents that run for a long time, survive failures and can pause for human approval. The open source license and self-hosting option suit teams that want control over where code runs. It is less suited to people who do not write code, since tasks are defined in your own codebase, and the pages describe a TypeScript-first workflow. Costs depend on compute seconds and run counts, so they need estimating from usage; the pricing page gives a worked example. The Free plan keeps log retention at 1 day, so teams needing longer history must pay. The pages list no free trial beyond the Free plan.

Frequently asked questions

Is there a free plan?

Yes. The Free plan costs $0 per month, includes $5 per month of credits and does not require a credit card. Once the included credits are used, you need to upgrade to keep running tasks.

How much do the paid plans cost?

Hobby is $10 per month and Pro is $50 per month. Enterprise pricing is custom. Usage beyond the included credits is billed at compute rates, plus $0.25 per 10,000 runs.

Can I self-host Trigger.dev?

Yes. The platform is open source under the Apache 2.0 license, and the pricing page links to a self-hosting guide.

Can it run Python?

Yes. Python scripts can be run from inside TypeScript tasks using the Python build extension, which installs Python and dependencies at build time.

Does it support HIPAA?

A signed Business Associate Agreement is available as a $500 per month add-on, so tasks handling Protected Health Information can run on Trigger.dev Cloud.
