Open Source Automation Tools
Automation is easy to build and brutal to maintain - every workflow you wire up becomes a silent dependency that breaks the day an API changes its response shape, and the failures show up downstream where they're hard to trace. The open source options below let you self-host the engine so your credentials and data never transit someone else's servers, and they keep flow definitions as files or records you can version, diff, and restore when a working automation suddenly stops.
