Prometheus leads on adoption by 1,146% (66,906 vs 5,371 stars). Prometheus is written in Go under Apache-2.0; ihp is written in Haskell under MIT. Prometheus has attracted 16% as many forks as stars, ihp 4%. Prometheus was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (hacktoberfest), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.
