Most pages here put a hosted SaaS against the open-source tool that replaces it, and price it properly: licence, server, and the hours it takes to keep alive.
Airtable has no self-hosted option at any plan, including Enterprise. Baserow ships an MIT-licensed edition you run yourself, with no per-user fee and no row cap beyond your hardware.
Ten times the free rows, cheaper per seat, and cloud data processed in German data centres. The catch is the licence above three users, where SeaTable stops publishing a price.
The pair where self-hosting saves the least. Free software on your own box is also the box that dies with everything else it was supposed to be watching.
There's a genuine free plan, capped at 100 tasks a month, and one trigger plus one action per Zap. It's enough to test whether automation solves your problem, not enough to run a business process on.
What counts as a Zapier "task"?
Each action step that runs counts as one task. A Zap with three action steps that fires once uses three tasks, not one, which catches a lot of people budgeting by "number of Zaps" instead of steps times runs.
Is vcusers.org affiliated with any of these tools?
No. No affiliate links, no sponsored placement, no vendor relationships. Every price and limit is read off the vendor's own public pages and dated on the page it appears on, so you can check it or catch it going stale.
