Which Workflow Automation tools are open source?

3 of the 28 we track have a public repository: Activepieces (NOASSERTION), Trigger.dev (Apache-2.0), PagerDuty (Apache-2.0). Licence matters more than the label — check whether the licence covers the production server as well as the library.

What does a Workflow Automation tool actually cost?

Published monthly prices run from $8 to $300, averaging about $52/month across 11 tools that publish a figure. 28 offer a free tier. The rest quote contact-sales or usage-based pricing, where the sticker price matters less than your usage volume.

Which Workflow Automation tools are actively maintained?

Most recent commits among the open-source options: Activepieces (2026-08-13), Trigger.dev (2026-08-13), PagerDuty (2026-07-15). A quiet repository isn't automatically a problem — a stable library needs fewer commits than a young one — but a year of silence is worth asking about.
