Huginn vs Zapier Comments
Comment by bulldogs · Sep 6, 2026
Huginn vs Zapier is mostly a question of who runs the box. Huginn is self-hosted, agents are plain Ruby, and there is no per-task meter, so chatty polling flows cost nothing extra; the price is uptime, upgrades, and a real learning curve. Zapier is zero-ops with a far bigger connector catalog, but per-task billing gets painful on high-volume triggers. No one to tend a server: Zapier. A dev who will: Huginn pays back fast.

UI.Vision RPA vs Zapier Comments
Comment by bulldogs · Sep 7, 2026
These solve different problems. Zapier talks to APIs, so it only reaches apps that expose one, but it runs hosted and on a schedule with your machine out of the loop. UI.Vision drives the interface itself with clicks, keystrokes, OCR and image matching, so it can automate a legacy portal or a desktop app that has no API at all. The cost is brittleness: a layout change breaks a selector, and something has to keep the browser open. API exists: Zapier. It does not: UI.Vision is one of the few free ways in.

Kantu#s workflow automation works locally on your machine. It does not run in the cloud. Therefore much better privacy and security. And its free.
Positive comment by jmcaterfield · Apr 11, 2019
Kantu runs locally and is open-source. So it is the best alternative if you can not use a cloud-based software because of high security requirements, such as in our campus network.
