Open source software development - api management
API management is the process of creating and publishing application programming interfaces (APIs), enforcing their usage policies, controlling access, nurturing the subscriber community, collecting and analyzing usage statistics, and reporting on performance. This page ranks 16 open-source API management projects by a health score recomputed every night from repository data; nothing else affects the order. Hasura leads at 98/100 with 97 commits in the last 90 days and 32k stars, followed by Opik (97) and Tyk (96). 14 of the 16 score 70 or above, 13 publish a Docker image, and the median health is 90. Apache-2.0 is the most common licence, carried by 7 of them. Between them they stand in for Typeform, Firebase and Kong Enterprise.

How the API management tools compare
Hasura edges Opik 98 to 97. Opik is the busier codebase, though, with 1,192 commits in 90 days to 97. Hoppscotch Community Edition has the largest following at 81k stars, yet ranks #7 of 16, held back mostly by commit activity (23 commits in 90 days).
The most recent release is Opik 2.2.134, published today. form.io publishes no tagged releases, which costs up to 25 of the 100 points. form.io scores under 40, so check recent activity before adopting it. By stack, Go (4), Nodejs (4) and PHP (2) are the most common. Hasura, Opik, Tyk and 10 more are permissively licensed; Fusio is copyleft. Composio and Hook0 are source-available rather than open source, which limits commercial reuse.
