We have data migration plans in work but it doesn't appear that a plausible migration is possible
Next.js, TailwindCSS, shadcn. the usual stuff
it's "ribbit"
from what i know, awstats gets analytics from server-side logs while Rybbit uses a client side script. So not really and apples to apples comparison
Clickhouse definitely takes a lot of resources! There's unfortunately no way around that, though in my experience it runs fine on the cheapest Hetzner instances which are like $3-4 a month for 2GB of RAM. How lightweight is your VPS?
And yea, you don't need clickhouse for a simple static site. I chose clickhouse because it Postgres or MySQL does not scale well since the main site I personally use Rybbit for sends around 20 million events a month.
It pains me to plug my competitors, but check out Umami or Goatcounter if you want a platform that uses postgres.
Only very slightly so. One of the reasons I created Rybbit is because platforms like plausible and fathom have much inferior self-hosted versions (very limited featureset and basically never updated). We have a comparison here
it didn't have enough features, especially since the community version is heavily nerfed (it's missing even funnels)
Yea, we use a client-side script like almost everyone else. The major difference is that we don't use cookies so you can avoid a lot of the cookie banner/GDPR nonsense.
Rybbit definitely isn't the first open source cookieless web analytics platform (Plausible and Umami are the two other big ones), but it's probably the most "all-in-one" of all these alternatives.
A few more screenshots in case you don't want to leave the site

as opposed to plausible community edition which is even more limited and is only updated a couple times a year?
