Just a log of “my transition” and what have works well.
I used Google Maps a lot. I have moved to https://mapy.com/ works surprisingly well for navigation and regular map need, not very strong in POI, but that was expected.
Google Analytics swapped for https://dashboard.simpleanalytics.com/ - should have done this way earlier, just an overall better product for my needs.
Exited Goodreads for https://app.thestorygraph.com/ - zero problems
ChatGPT/Gemini moved to https://chat.mistral.ai/ - this one is a slight downgrade on both functionality and results. (so I am still cheating a bit on this one)
Moved to here, PieFed from Reddit - not regrets.
I was using Brave and Duckduckgo/EcoSia from before. I would consider moving away from Brave for a similar private but European browser.
From my experience public transport was super hard to find a good solution too. I ended up going with Citymapper which works amazingly well. It’s a British company from London but unfortunately uses Google Maps API I believe, so not truly independent.
Haven’t found anything even close to a replacement though.
