How the integrated library system tools compare

RERO ILS edges Koha 88 to 56, and most of the difference is release recency: v1.30.1 from today against no tagged release. Koha is the busier codebase, though, with 1,076 commits in 90 days to 90. Koha has the largest following at 596 stars, yet ranks #2 of 3, held back mostly by release recency (no tagged release).

The most recent release is RERO ILS v1.30.1, published today. Koha and Evergreen publish no tagged releases, which costs up to 25 of the 100 points. None of the measured options scores under 40. By stack, Perl (1), PLpgSQL (1) and Python (1) are the most common. RERO ILS, Koha and Evergreen are copyleft.
