IFTTTAbout Huginn
Huginn predates the modern automation wave — since 2013 it has let people build 'agents' that watch the world and react: scrape a page for changes, track a price, monitor a feed, detect a keyword on social media, then email you, post a webhook or trigger another agent.
Its event-graph model is genuinely powerful: agents emit events other agents consume, so sophisticated monitoring pipelines grow out of simple building blocks. The Website Agent alone — point it at any page with CSS selectors — replaces a shelf of paid scraping tools.
It shows its age: the Rails UI is utilitarian, setup takes real effort, and development has slowed to maintenance pace. But nothing self-hosted matches its watch-the-web flexibility per dollar (that dollar being zero — it's MIT licensed), which is why 49k+ stars keep it a fixture of every homelab list.
What makes it different
Website changes, RSS, email, weather, social keywords — dozens of agent types out of the box.
Agents emit events other agents consume — build monitoring pipelines from simple blocks.
The Website Agent extracts data from any page with CSS selectors, on your schedule.
MIT-licensed and self-hosted — your monitors, credentials and data never touch a third party.

DockerThe honest read
- Unmatched flexibility for web monitoring and scraping
- 12 years of community recipes and agent types
- MIT license — free forever, no tiers
- Runs on a small VPS or Raspberry Pi
- Event-chaining enables genuinely complex pipelines
- Dated Rails UI and developer-grade setup
- Maintenance-mode pace — few new integrations
- No modern SaaS connector library
- JSON-based agent configuration is unforgiving
Quick answers
Yes, at a maintenance pace — dependencies and fixes land steadily, though major new features are rare. The core has been production-stable for years.
Watching things: page changes, prices, feeds, keywords — then chaining reactions. For SaaS-to-SaaS business automation, n8n or Activepieces are better fits.
It's the most involved tool in this space — a Rails app with MySQL/Postgres, best run via the official Docker image. Budget an afternoon and it then runs for years.
Completely — MIT-licensed open source with no paid edition at all.
