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 :-)

Your self hosted option only works for up to 5 employees and prices for more are not listed.

There are a few lesser known projects, I used.

Trillium - 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.

I 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?

If you pay for obsidian sync, you have device specific selective sync options: https://obsidian.md/help/sync/settings#Selective+syncing

Honestly 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 doesn't do classic "wiki" things like bi-directional linking. Search, ironically, is also a bit of a mess.

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.

Obsidian.

Checks 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/sorting

Thanks for checking it out. Pricing for self-hosted option is the same as hosted. But I'm happy to offer a discount on top of that for larger teams.

From what you say, I would say Notion is, indeed, the best option. You could also try an app like Obsidian or any more specific app in any App Store. You could even go as far as using AI (even a locally host model if you want full control/privacy), that will keep a wiki up to date for you by having you just input “raw” data.

I use EIDARA (https://eidara.dev) – a compiled markdown system I built. It compressed my projects context from ~30K tokens across different .md files to a single ~3.5K file that works across Claude, GPT, and DeepSeek. I am managing 10+ projects without re-pasting anything between sessions.
