How We Use Trigger.dev to Run AI Agents That Work While We Sleep

Quick Summary

Our AI agents run 39 automated tasks — content research, email triage, social monitoring, invoice generation. Here’s how Trigger.dev makes it possible.

Right now, our server is probably really busy. There are artificial intelligence agents working all the time, doing different jobs in the background. One of them might be looking for popular topics at this very moment, while another is making a report for a meeting that’s coming up soon. Maybe another one is going through emails from the last few hours, looking at the information and analyzing it. No matter what the job is, you can be sure that our AI agents are working hard to get it done. They are always on, always working, and always trying to help. This means we can get things done faster and more efficiently, which is really helpful. Our AI agents are like a team of workers who never take a break, always doing their part to make sure everything runs smoothly.

We’ve got 39 automated tasks that make our lives easier when it comes to creating content, handling operations, and managing our social media presence. Some of these tasks are set to run at specific times, while others can be kicked off manually – it’s totally up to us. The best part is that they all just hum along in the background, so we don’t have to babysit them all the time. This frees us up to focus on more important things, and it’s definitely made our work more efficient. With these automated tasks taking care of the behind-the-scenes stuff, we can concentrate on the things that really matter.

Let’s take a closer look at Trigger.dev, the platform that makes all this possible. I’ll give you a step-by-step guide on how we use it, because to be honest, most of the hype around “AI agents” is just about showing off fancy demos, not real systems that are actually used in production. We’ll dive into the details of how Trigger.dev works and what makes it so useful for us. I want to show you the real-world applications of this platform, not just some fancy demo. We’ll explore the nitty-gritty of Trigger.dev, and I’ll share with you how it helps us get things done.

This is a production system. Here’s how it works.

What Trigger.dev Actually Is

What Trigger.dev Actually Is

What Trigger.dev Actually Is

  • Cron is fine for simple scripts but has no retry logic, no monitoring, no concurrency control, and crashes are silent.
  • n8n is excellent for visual workflows but awkward for heavy code logic. When your task needs to call Claude’s API, parse the response, write to a database, generate images, and post to Slack — n8n becomes a mess of code nodes.
  • Lambda has a 15-minute timeout. Our blog content pipeline can take 20+ minutes for research, writing, QA, and image generation. Lambda kills it mid-sentence.

What Trigger.dev Actually Is

Our Task Architecture

Trigger.dev is a background job platform for TypeScript. Think of it as a modern cron system that also handles retries, queuing, concurrency control, and long-running tasks. You write tasks as TypeScript functions, deploy them, and Trigger.dev handles the execution.

Cron is fine for simple scripts but has no retry logic, no monitoring, no concurrency control, and crashes are silent.

  • Weekly content calendar planning
  • Daily blog topic research
  • Blog writing pipeline (research → draft → QA → media → design → publish)
  • LinkedIn post generation
  • X/Twitter thread drafting
  • Newsletter compilation
  • YouTube script generation

n8n is really good at handling visual workflows, but it can get a bit clumsy when you need to deal with complex code logic. For example, if you have a task that requires calling Claude’s API, parsing the response, writing to a database, generating images, and posting to Slack, n8n can become overwhelming with a bunch of code nodes. It’s like trying to force a square peg into a round hole – it just doesn’t fit neatly. In situations like this, you might need to look for alternative solutions that can handle heavy code logic more efficiently.

  • Email triage every 2 hours
  • Daily meeting prep briefings
  • Invoice generation on demand
  • Proposal drafting from voice memos
  • Daily metrics dashboard
  • Weekly business report

Lambda has a 15-minute timeout. Our blog content pipeline can take 20+ minutes for research, writing, QA, and image generation. Lambda kills it mid-sentence.

  • Daily trend scanning
  • Instagram content with AI images
  • Engagement monitoring (twice daily)
  • Monthly social performance report

The Model Tier System

Our Task Architecture

  • Haiku (cheap, fast) — Categorization, data extraction, simple summaries. ~$0.001 per call.
  • Sonnet (balanced) — Analysis, report generation, email drafts. ~$0.01 per call.
  • Opus (premium) — Blog posts, proposals, social media copy. Anything customer-facing. ~$0.05 per call.

The Numbers

Newsletter compilation

  • 39 tasks running on schedule + on-demand
  • ~$50/month in AI API costs (tiered model approach)
  • $10/month Trigger.dev Hobby plan
  • 80-100 hours/month of work automated
  • Zero incidents of AI content going live without approval
