- SourceHut as an alternative git foundry, https://sr.ht
- Any HedgeDoc deployment , like https://pad.nixnet.services/
- Any jitsi meet deployment, like https://meet.jit.si/
- KeyOxide for online identity verification (using gpg), https://keyoxide.org/
- PlantUML for drawing all kinds of diagrams based on formal text descriptions (online version: https://www.plantuml.com/plantuml/uml/, but mainly just an offline tool). I’d encourage people not to use online services for everything but simply rely on good tools.
- Freesound.org (https//freesound.org) for sound fragments
- TrekCore.com for Star Trek sounds ;) https://www.trekcore.com/audio/
- Bookwyrm as a fediverse alternative for sites like goodreads (tracking and reviewing books): https://bookwyrm.social/
- Fotostrips.nl if you’re dutch and like comics
And in general I’d wish more people would use RSS (and more sites would prominently offer it) to aggregate things like news.
Specifically for lemmy: https://browse.feddit.de/, to find more smaller communities you like and help them grow.
Can I offer a non tech site?
A bit niche - train travel around the world - but if you want to travel between countries by train, or several countries, or cross country, this is THE site. I’ve used it for inspiration, and for checking whether a mad idea I’ve had is feasible, and for planning.
I’ve done a few trips by train and often people are amazed at my travel know-how but in reality I have none, the guy who makes this website does, and he makes it all incredibly easy. Timetables, prices, options, suggested routes, links to buy tickets, what to expect from the train facilities, it’s all in there.
squoosh.app - Easy to use image compression without upload
Great amount of free and gratis services, love the work they are doing.
https://www.erowid.org/ with plenty of resources for harm reduction. In case you or a loved one is a drug user, at least you can help them (or yourself) to not hurt them too much
I always found it funny that the domain was an anagram of weirdo.
