But even from a code perspective I'm not sure comparing repos is always all that useful. I'm not sure about Grav but on the Kirby side, if I'm not mistaken, the current official repo started with the v3 and the two previous versions were archived. So you're only comparing the code activity from ~2019 onwards but Kirby has been around for more than 10 years at this point.
Thanks for the additional info. If we are were to just look at the repo stats, Kirby is a lot more active than Grav right now. Do you happen to know what the archived repos were and if they are public? If you look at https://devboard.gitsense.com/getkirby you can see the insights for all the kirby org repos
I do want to make it clear that Kirby is a very healthy project, if anybody is misinterpreting the data.
They are not available as far as I can tell. If memory serves me well, the current kirby repo had a different name during v3 development and the code for v2 was living in another repo also named kirby. When v3 went live they renamed the two so that v3 became the kirby repo currently online and the old one became kirby-v2 or something like that. And that repo has now being archived apparently.
