Selfhosted

56772 readers

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

  7. No low-effort posts. This is subjective and will largely be determined by the community member reports.

Interesting tool based on blocks to tag any document for photos you own. With app to allow access from any device. Blocks contains tags and links between them to organize all like a heap.
I haven't installed the self-hosted version yet to see how it can interact with an existing Obsidian vault. Next step.

Some notes:

  • This can be self-hosted. My working compose.yml is below
  • Free until August, and he has a discord for feedback, but I can't find the invite. It was in the live-stream he did.
  • He said in the stream that he's open to open sourcing the project. Just not there yet.
  • He admits the licensing is a little confusing. He stressed that self-hosting does not have a storage or block limit. Also, self-hosting is possible with all licenses (I think).
  • Supports macOS, Linux, Windows, iOS, and Android (in beta I think)

I have the DB, config, and thumbnails on local NVME, and storage on NFS-mounted NAS. Working fine so far.

ETA: Correction in compose file.

Does it store uploaded files in plain text on the file system?

[–] ClownStatue@piefed.social 1 points 1 day ago

From what I can tell, notes are stored in the DB, but can be exported as JSON, or I think markdown. It sure about markdown. I’ve only been able to export JSON, and it didn’t include the image I had embedded in the note. Whatever isn’t a note (images, movies, pdf, doc, etc.) is stored on the file system in a directory structure that files them under heap -> asset checksum. Thumbnails are included there if applicable. In that regard, it kind of forces you to use its folder structure.
