Ask HN: What is your go-to solution for a personal wiki in 2026?

7•ex-aws-dude•1h ago

I've used Notion for a long time but I'm interested to hear what other alternatives exist in 2026?

For me the main requirements are:

* Backed up to cloud

* Has a mobile app that is easy to make small changes (for example if I'm doing an oil change on my car I need to be able to pull out my phone and log it in the wiki easily)

* Simple file format like markdown so that you're not locked into something proprietary (no need for crazy formatting options like MSWord)

* Option to export data out as a backup

* Allow uploading arbitrary files like PDFs, images, receipts etc...

* Nice to have: support for inline tables of data with simple calculations/sorting

For a personal wiki I would use wikijs

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?

The Fossil SCM (<https://fossil-scm.org>) meets most of your requirements, noting that:

- "mobile app" means "its web interface"

- "backed up" means to wherever you upload/sync your backups to

- No automagic table calculation support.
