Thank you!
I'm the maintainer of the project and it's so heartwarming to see it being recommended on this forum.
All the projects mentioned here are great. What I think sets Plausible apart is that we've managed to create a profitable business around a 100% AGPL-licensed codebase (i.e. no dual-license for enterprise version). This means we can keep investing into the product and adding new features without being in the 'thankless OSS maintainer' role that so often ends in burnout.
We're currently working on importing historical data from Google Analytics into Plausible[1] which should make switching even easier for many folks. Stay tuned.
