TL;DR

Obsius Publish generates a shareable URL for individual Obsidian notes, making it ideal for quick “send to a few people” sharing.

Briefing

Obsius Publish offers an easy, free way to share individual Obsidian notes online via a hard-to-guess URL—useful for “send this to a few people” moments, but not a true privacy solution. Unlike Obsidian Publish (the paid, fully featured sharing service), Obsius Publish is a third-party, free, open-source community plugin designed for one-off notes that don’t need the full public publishing experience.

The core workflow is straightforward. After installing Obsius Publish from Obsidian’s community plugin browser and enabling it, users get new commands in the Command Palette. Publishing a note is done by running “publish to Obsius,” which generates a URL that can be copied to the clipboard. A practical tip is to store that URL back into the note itself (e.g., in a custom property like “Obsius URL”) so the link can be reused later. Clicking the generated link opens a public web page containing the note’s content, including embedded elements such as iframes and links.

Updates and removals are also supported, but with small quirks. After publishing, users can run an “Update in Obsius” command to push changes. In testing, the update sometimes returns a failure message even though the content still updates correctly—an error that appears to be messaging-only rather than functional. To revoke access, users can run “Remove from Obsius,” after which the page returns a 404 Not Found on refresh, indicating it has been deleted from the Obsius server. A separate command lists all currently published posts, helping users prune what they’ve shared.

The plugin’s limitations shape when it’s appropriate. It’s built for individual pages rather than a connected publishing site: WikiLinks or internal markdown links won’t automatically become clickable on Obsius because the plugin doesn’t parse and match published pages into a navigable graph. If multiple notes are published, linking to them on Obsius requires using the external URL instead of Obsidian’s internal link format. There’s also no bulk publishing or automatic table-of-contents style navigation—each page must be published individually.

Privacy is handled through “security through obscurity,” not access control. Anyone who has the URL can view the note, so sensitive material shouldn’t be included. The creator’s own caution includes testing whether the plugin reads other notes: developer tools showed that requests appear to send only the exact content of the selected note (not the rest of the vault), though users are still encouraged to do their own checks. Finally, because the service is free and run by a single developer funded by donations and coffee purchases, longevity is uncertain; links shouldn’t be treated as mission-critical. Overall, Obsius Publish is best viewed as a lightweight, temporary sharing mechanism for notes meant to be read once or twice by a small audience—not as a secure private document vault.

Cornell Notes

Obsius Publish is a free, open-source Obsidian community plugin that turns a single note into a shareable web page using a hard-to-guess URL. It’s designed for quick, semi-private sharing to a small group, not for fully private documents or large-scale publishing. Users publish via the Command Palette, copy/store the generated URL, and can later update or remove the note (removal leads to a 404). The plugin doesn’t automatically convert Obsidian internal links (WikiLinks) into clickable links on Obsius, and it lacks bulk publishing or automatic navigation features. Because anyone with the URL can access the content and the service depends on one developer, users should avoid sensitive or mission-critical information.

How does Obsius Publish share a note, and what does the generated URL imply for privacy?

Obsius Publish creates a web page for a specific note and provides a URL that can be copied (and optionally stored back into the note). Access is effectively “anyone with the link can view it,” since there’s no user-based permission system described. That means the URL functions as the only barrier, so content should be limited to what the user would be comfortable sharing publicly.

What commands are used to publish, update, and revoke a note, and what quirks show up in practice?

Publishing is done through a “publish to Obsius” command, which copies the URL to the clipboard and can be assigned a hotkey. Updating uses an “Update in Obsius” command; in testing, an error message appeared even though the page content still updated, suggesting a messaging bug rather than broken functionality. Revoking uses “Remove from Obsius,” after which refreshing the page returns 404 Not Found, indicating deletion from the Obsius server.

Why don’t Obsidian internal links automatically work between published notes on Obsius?

Obsius Publish is oriented around one-off pages and doesn’t parse the set of published posts to match internal WikiLinks/markdown links to their published counterparts. As a result, internal links may not become clickable on Obsius. If both notes are published, linking to the other note on Obsius requires using the external Obsius URL rather than Obsidian’s internal link format.

What publishing features are missing compared with a more full-fledged publishing service?

There’s no bulk option to publish everything (or automatically publish all posts) and no automatic hyperlinked index or table of contents. Instead, the plugin supports publishing pages individually, which makes it better suited to small, targeted sharing rather than building a navigable public site.

What security concerns should users consider before publishing, and what did the transcript’s testing suggest?

The main concern is that the plugin relies on obscurity: anyone with the URL can access the note. The transcript also describes testing with browser developer tools to see what the plugin sends during update requests. The observed payload appeared to include only the exact content of the selected note, not other notes in the vault. Even so, users are advised to do their own research and consider using a separate vault without sensitive information.

Why might Obsius Publish be a poor fit for mission-critical sharing?

The service is free and maintained by a single developer supported by donations and coffee purchases, raising uncertainty about long-term availability. The transcript advises treating the links as temporary—appropriate for notes meant to be viewed briefly by a small audience, not as durable, guaranteed storage for critical information.

Review Questions

  1. What privacy model does Obsius Publish use, and how does that affect what kinds of notes you should publish?
  2. How do you update and remove a published note, and what outcome should you expect after removal?
  3. What limitations exist around internal links (WikiLinks/markdown) when multiple notes are published to Obsius?

Key Points

  1. 1

    Obsius Publish generates a shareable URL for individual Obsidian notes, making it ideal for quick “send to a few people” sharing.

  2. 2

    Anyone with the URL can view the note, so it’s not a true private sharing system and shouldn’t be used for sensitive content.

  3. 3

    Publishing, updating, and revoking are handled through Command Palette commands; removal results in a 404 Not Found page.

  4. 4

    Internal Obsidian links (WikiLinks/markdown) don’t automatically become clickable on Obsius, so cross-note linking may require using external Obsius URLs.

  5. 5

    The plugin lacks bulk publishing and automatic navigation features like a table of contents; each page is published individually.

  6. 6

    Developer tools testing described in the transcript suggests update requests include only the selected note’s content, but users should still verify and choose a safer vault strategy.

  7. 7

    Because the service is free and maintained by one developer, links shouldn’t be treated as mission-critical or guaranteed to last.

Highlights

Obsius Publish turns a single note into a web page via a hard-to-guess URL, but URL possession equals access.
Update and remove are supported; removal leads to a 404 Not Found, effectively revoking visibility.
Obsidian internal links don’t automatically translate into clickable links on Obsius—external URLs are needed for cross-note navigation.
The plugin’s privacy relies on obscurity, and the transcript recommends avoiding sensitive or mission-critical notes.
