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 2026-10-14 and 2026-10-15, 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. 10 of 10 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.
1 of the 10 free tools describe themselves, in their maintainers' own words, as an alternative to the tool they sit beside. The other 9 do not name theirs, so those pairings are not their maintainers' claim, and each one says so. Every description is quoted underneath its tool. Stars, contributors and last commit came from the GitHub API on the same day as the prices.
All 10 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.
