Free of licence, not free of cost.

Self-hosting means a server and the time to run it. The free tools here cost $0 to license; the paid prices are the cheapest paid tier in US dollars on the day shown, and they change. “Open source” is only shown where the repository declares an OSI-approved licence.

How these were checked

Every price was read off the vendor's own pricing page, rendered in a real browser on 2026-09-15, taking the cheapest paid tier in US dollars. The page and the date are listed against each one below, so you can check any of them yourself.

Quoted or computed. Each entry shows the price as the page prints it. 12 of 12 appear on the vendor's page word for word. Anything worked out from those figures is labelled computed and shows its arithmetic, so a number we calculated cannot be mistaken for one a vendor published. The only computed figures here are the yearly costs and the totals.

Every free tool here describes itself as an alternative to the tool it sits beside, in its maintainers' own words, quoted underneath it. Stars, contributors and last commit came from the GitHub API on the same day as the prices.

All twelve free projects had been committed to within the last 90 days.

Self-hosting is not free of cost — it is free of licence. A server and the time to run it are yours to pay either way, and nothing below pretends otherwise.
