3. obsidian-dataview

   2 119 9,057 5.7 TypeScript

   A data index and query language over Markdown files, for https://obsidian.md/.

   

   No, Obsidian is quite more powerful.

   Obsidian has built-in support for markdown, images, PDFs, canvas (via JSON Canvas which they developed and open sourced https://obsidian.md/canvas), and others.

   For databases, you can add fields/properties both in the markdown frontmatter or in the text and query it via very popular plugins:

   https://github.com/blacksmithgu/obsidian-dataview

   There are tons of community plugins that support all kind of stuff: tasks, kanban, LLM/Copilot, graph analysis of links, charts.

   It can also be extended in JS, both writing your own plugins or via a few plugins that allow limited JS support.

   ---

   Obsidian is actually quite good as a NoCode prototyping platform for personal apps :-)

   E.g. CRUD:

   - Use templates, via Templater: to define the content of your data

   - Use links and tags to define relations and connections

   - Use dataview or graphs for views

   - There are even plugins to define buttons and the actions they perform, if you need commands

5. Trilium Notes

   4 293 36,432 10.0 TypeScript

   Build your personal knowledge base with Trilium Notes

   

   I can also recommend Trilium Notes [1], which I have been happily using for years. It's currently in "maintenance mode", which I personally see as a feature (no risk of bloatware).

   Self-hosted, great webapp, optional native clients and works offline.

6. Notes

   5 7 2,914 10.0 TypeScript

   Discontinued Build your personal knowledge base with TriliumNext Notes (by TriliumNext)

   

   As another fan of Trilium Notes for years, I just want to add that there is now also an active community fork continuing the work on the tool.

7. flatnotes

   6 22 3,103 7.3 Vue

   A self-hosted, database-less note taking web app that utilises a flat folder of markdown files for storage.

   

   I've been experimenting with Flatnotes (https://github.com/Dullage/flatnotes) for a while and really like the design. No notebooks or even folders, just a single directory with markdown files and decent search & tagging. It feels a lot like what happened to email when we gave up all the up-front structuring with deep hierarchies and just said index it and we'll find it when we need to.

   The project is just "good enough" for what I need, and aside from tiny bugs whenever I find a gap I can either work around it or live without. Constraints are a powerful motivator for both creativity and getting stuff done.

8. nvpy

   7 5 854 7.3 Python

   Simplenote syncing note-taking application, inspired by Notational Velocity and ResophNotes, but uglier and cross-platformerer.

   

   I use folders for my data. a-z. This is the basic directory structure. b->books->management for example.

   Does not solve the fundamental problem of a file system that you also could file this under m->management->books

   I use recoll to index and find things. https://www.recoll.org/ And yes, I have a 20 TB HDD. Quite a bit of data and media. If someone knows how to make an encrypte mirror of my drive with https://www.opendrive.com/ I would be interested. No incremental backups, if possible I would like to access it like a drive.

   For my notes I just use light speed fast nvpy with simplenote.com to synchronized with several computes. https://github.com/cpbotha/nvpy

   My notes don't follow the a-z approach but have regular headlines. I use nvpy as a mixture between a to do list and a knowledge database. For to do I have recently thought of using paper cards for kanban, but I am not sure. Suggestions welcome.

9. termux-gui

   8 27 1,125 3.6 Kotlin

   A plugin for Termux to use native Android GUI components from CLI applications.

   

   > but I wish there was some way to slap a basic UI on top of a CLI application for mobile

   I have only relied on fzf so far but have played with the various components of the Termux:API [0] for basic UIs, and it works well.

   There is also Termux:GUI [1] with Bash bindings which allows to build more advanced UIs.

12. syncthing-android

    11 1,248 3,627 9.1 Java

    Discontinued Wrapper of syncthing for Android. (by syncthing)

    

    What is the good solution to sync text files? I haven't found a good solution that is open source and self-hosted. Ideally, eventually, my setup should give me real time syncing the same level as multiple people editing the same file. But that is a stretch goal.

    I am currently using Syncthing but unfortunately it's client app has been removed from Google Play [1]. I am managing with Syncthing-Fork.
