Obsidian Sync
Sync keeps your vault up to date across devices that have Obsidian installed, with version history and shared vaults. It does that really well.
Tephra lets you read your vault on devices that don't have Obsidian at all.
Tephra is a web app for your Obsidian vault that you run on your own server. A plugin
keeps it synced with Obsidian on your devices, so you can open your notes at
notes.yourname.com from any computer, with links, backlinks and graph
view working the way you expect.
Self-hosted · Your domain · Your login · AGPL-3.0
Obsidian stores your vault as plain files on your own devices, which is great until you need a note and none of those devices are around. Tephra gives you another way in. It doesn't do everything the app does, but it runs on your server and works in any browser.
Run a single container on your server, on any subdomain you like.
Add the Tephra plugin to Obsidian on desktop or mobile. It keeps the server up to date.
Log in from any computer and your vault is right there.

[[Links]] work, including links to headings and blocks.
See how your notes connect and click around.
Images and PDFs open right inside the note.
It looks and feels like Obsidian.
The plugin works in Obsidian on desktop, iOS and Android.
A single container on your own server and domain.
Make quick fixes to a note from any computer.
Edits made on the web sync back to your devices, merged properly so nothing gets overwritten.

Make specific folders public if you want to.
Right now Tephra supports CommonMark Markdown, YAML frontmatter, headings, tags, Markdown links, Obsidian wikilinks (including heading and block links), and image/PDF attachments. It doesn't run community plugins, Dataview, Templater, custom JavaScript or custom CSS yet.
Pick a cloud, follow along, and your vault is in a browser tab before your coffee gets cold.
Pick a home for it. Each one has its own short, copy-paste guide.
You'll come back with two things: your Tephra web address and a one-time setup token.
Open your Tephra address. Choose an email and password, paste the setup token, done. This one login works on the web and in Obsidian.
On the device with Obsidian, tap these two buttons in order.
If Tephra Sync isn't switched on yet, flip it on in Settings → Community plugins.
Open Settings → Tephra Sync and work down the page.
From here on it syncs by itself whenever you change a note.
That's it. Open your Tephra address in any browser and your whole vault is right there.
Tephra is the ash and rock a volcano throws into the air when it erupts. The word comes from the Ancient Greek τέφρα, meaning ash.
Obsidian is named after volcanic glass. As its makers put it, if your raw thoughts are lava, Obsidian is your crystallised knowledge.
Tephra comes from the same eruption, but it's the part that travels. Your vault stays where it is, and Tephra carries it far enough that you can read it from anywhere.
Set up the server, install the plugin, and your notes are a browser tab away from any computer.
