Hashing only works if the website stores their passwords correctly. If a single website you use doesn’t hash passwords correctly, and gets their database leaked, then your passwords will all be leaked. Changing a few characters per site may help a bit, but it shouldn’t be relied on.
Also, if you’re worried about the host shutting down, you should try bitwarden. It’s completely open source, and you can self host it if you want.

Changing even a single letter will completely scramble your password with hash, so for all intents and purpose it is equivalent to a unique password
Though I do admit it can get a bit tedious, I’ll definitly look into self-hosting, thanks for the recommendation
