An AI assistant - not entirely sure what the difference to e.g. MyCroft is - but seems a little newer, coming along well. Can be integrated with a variety of TTS and STT services, and skills created for it

Simple file server, also with webdav abaility. You can control if you want to enable editing, searching, uploading, access control and more. Still remains with a relatively simple cli interface to quickly bring up a server (e.g. dufs -A downloads to serve your downloads directory with full access/write permissions)

A search engine for websites, embeddable and easily customized. Have seen it run without javascript in my browser, so perhaps it runs on client or server-side js?

Shipping web projects should be fast, easy, and low risk. Surge is static web publishing for Front-End Developers, right from the CLI.

Quickly deploy static web pages through the cli. Similar to netlify, now.sh and so on. Can be integrated with e.g. woodpecker ci systems with a simple plugin to have preview environments which get automatically destroyed after merging PRs.

An interesting take on dynamic gemini pages: You add %%%-delineated code-blocks which execute shell code.
The output is displayed.
You can have inline variables mimicking shell variables prefixed with % as well (e.g. %$my_awesome_variable).

With those two building blocks you have a very simple concept, but leadin gto powerful dynamic execution:
Want to execute an advanced python script? Just call it from your shell code!

I am not entirely sure about security implications, however.

An open source, self-hosted implementation of the Tailscale control server

Perhaps the best-looking sub/air-sonic server implementation I have seen. Seems to be single user only however from what I can tell, which makes it harder to use with friends. Nevermind, it actually has multi-user support, though it seems to be single-library only.

Your own lastfm! Sweet if you just wanna track and get an overview of your listening habits without all the tra-ra of social connections.

A self-hosted version somewhat akin to something like nomie or jrnl. Supports markdown and can be interacted with through API - so could easily also be integrated with for example jrnl to auto-upload or download new entries.

Upload stuff and share with others, have it be deleted automatically after a while, or a certain amount of downloads. Simple, efficient, AWS S3 supported.

Super promising LDAP service for self-hosting (and specifically targeted at smaller self-hosted setups, with many examples - for Nextcloud, Bookstack, Jellyfin, Emby, Gitea, etc).

Self-hosted outdoor activity tracker :bicyclist:. Contribute to SamR1/FitTrackee development by creating an account on GitHub.

Fediverse-aware fitness tracker. Can be self-hosted, still in somewhat early development I would estimate. Privileges biking/running/skiing - activities getting you between two points - since it is pretty tightly integrated with gpx files and openstreetmap.

A nice and easy startpage setup for self-hosted apps or personal bookmarks.
Allows (a single?) user authorization to customize bookmarks and apps.

Intended for small homelabs and personal servers I would assume.
But nice and simple design and setup!

A fork of overseerr, which is a more stable/modern re-do of ombi which is a way to request movies, series, etc from your htpc mediabox setup.

A nice piece of software and easy to understand.

Self-hosted audiobook and podcast server. Contribute to advplyr/audiobookshelf development by creating an account on GitHub.

Leightweight go implementation of the audio streaming *sonic (SubSonic/AirSonic/...) server variants.

Ideal for a raspberry pi streaming platform I supposed but probably usable anywhere a light music server is useful. Might integrate well with beets?

An out-of-the-box solution to self-hosting a wide variety of services without much setup.
Can be used to implement IRC, Matrix, XMPP and E-Mail hosting for a circle of friends (also takes care of simple account management afaik); some web office software (collaborative editing, wiki, website hosting) file sharing (I2p, torrent, bepasty, plain file sharing) and privacy uses (metasearch engines, proxying, i2p).

Everything seems to be documented pretty nicely on the debian wiki. Probably less flexible than docker container setup but not bad.

Music streaming self-hosting discussion. In-depth and comparing a lot of different options like icecast, navidrome, funkwhale, snapcast, subsonic, airsonic, mpd, mopidy etc.

Make lists of what's in your fridge, when it expires, what you want to cook for the week, what's missing for that and put it on your shopping list of you need it.

Self-hosted google photos-like image hosting (and video!). Looks slick, simple enough but featureful enough in a sweet spot to make self-hosted image storage a cinch.

Supports automatic image tagging as well and has an android app on fdroid.
