https://hyperclast.com/ I built it because Notion is way too slow. I loved Obsidian, but I wanted it to be multi-player so my whole team could use it. It is fast, open, and self-hostable. It meets all the criteria you listed except the mobile app. Mobile app will be out next week. I'd happy to build any other features you need. Just let me know at k@hyperclast.com :-)

#12Trillium - https://triliumnotes.org/
Joplin - https://joplinapp.org
I personally use Flatnotes - https://github.com/Dullage/flatnotes with a connected git repository, but this does not meet your requirements.

#13I was on Obsidian for a while, moved away to try Supernotes and other competitors, and now I'm in the process of moving back to Obsidian. Has everything you want I think with plugins to do a ton more while still essentially being just Markdown.
The part I'm a bit confused about with obsidian is how it works with a mobile app My understanding is every device syncs its own full copy of everything? So if you have a lot of images/PDFs, does your phone have to be able to hold everything at once?

#14It meets all your requirements. Markdown interop is very good. Always backed up and in sync. Supports offline access. Really easy to export everything if you really need to.

#15Honestly the simplest option is sometimes the answer. Google docs... It meets all your requirements. Markdown interop is very good. Always backed up and in sync. Supports offline access. Really easy to export everything if you really need to.
Google Docs was built as a MS Word competitor and that's what it does best. I love Google Docs and I use it every day, but this is one thing I wouldn't use it for.

#16Checks all of your boxes:
- Backed up to cloud
- Has a mobile app that is easy to make small changes
- Simple file format like markdown
- Option to export data out as a backup (it's just markdown files, you don't even need to export, just copy them. Or export to PDF)
- Allow uploading arbitrary files like PDFs, images, receipts etc... (https://obsidian.md/help/file-formats)
- Nice to have: support for inline tables of data with simple calculations/sortingRe: Ask HN: What is your go-to solution for a personal wiki in 2026?
