Logseq: A Free & Open-Source App to Create Notes, Manage Tasks, Build Knowledge Graph, and More

Brief: Logseq is a versatile knowledge platform with the support for Markdown and Org-mode. You can create tasks, manage notes, and do a lot more things with them.

In the age of information, it is crucial to properly organize your thoughts, task list, and any other note related to your work/personal life.

While some of us choose to use separate applications and services, how about using an all-in-one open-source, privacy-friendly app to do it all?

That’s where Logseq comes in.


Logseq: Privacy-Friendly Knowledge Platform with Markdown & Org-mode Support

Logseq aims to help you organize, create to-do lists, and build a knowledge graph.

You can use existing Markdown or org-mode files to simply edit, write, and save any new notes.

Officially, Logseq is still in the beta testing phase, but it has been getting recommendations since being in the alpha stages.

Not to forget, it can be a nice open-source alternative to Obsidian as well. By default, it relies on your local directory, but you can choose any cloud directory to sync via your file system. So, you get to control your data.

If you haven’t set up any cloud storage, you can try using Rclone, Insync, or rsync commands.

Logseq gives powerful abilities and also supports plugins to expand the functionalities further. Let me highlight some of the key features to help you decide.

Features of Logseq

logseq themes

Logseq offers all the essentials for a knowledge app platform. Here’s what you can expect from it:

  • Markdown Editor
  • Org-mode File Support
  • Backlink
  • Page and block references (link between them)
  • Page and block embed to add quotes/references
  • Support for adding tasks and to-do lists
  • Ability to add tasks as per priority or by order A, B, C..
  • Publish pages and access it using localhost or GitHub pages
  • Advance commands support
  • Ability to create a template from your existing resource to re-use it
  • Page alias
  • PDF highlights
  • Create cards and quickly review them to memorize things
  • Excalidraw integration
  • Zotero integration
  • Add a custom theme by simply creating a custom.css file. There are available community-made files for quick use as well.
  • Custom keyboard shortcuts
  • Ability to self-host Logseq
  • Cross-platform support

Even though it’s beta software, it worked as expected in my brief testing. I’m not an advanced user checking the impressive knowledge graph, but if you have numerous Markdown notes, you can add them, link them, and check the generated graph yourself.

I was able to add tasks, link pages, add references, embed pages, check the knowledge graph for my existing data.

You can always change the theme from the marketplace and add functionalities using plugins, and this should help you personalize the experience for your workflow.

I found it incredibly easy to use, and the documentation explains everything nicely if you get stuck somewhere.

Install Logseq in Linux

You can find the AppImage file in its GitHub releases section for pre-releases and beta versions. Additionally, you should also find it listed on Flathub. So, you can install it on any Linux distribution of your choice.

If you need help, you might want to refer to our AppImage and Flatpak guides to get started.

In either case, you can head to its official webpage to know more about it.

  • Once I knew, obsidian wasn’t FOSS, I wanted to switch but man oh man does it use too much RAM. Staying with Obsidian for the mean time. I believe the switch would be easy since you could sync these programs together, I just find it hard to justify a note taking app almost consuming 1GB of RAM while the competitor (Obsidian) barely reaches 200MB.

  • Although I got the idea of pages and graphs to connect and organize information. To me, it’s pretty confusing to take notes “sequentially” by date. For now, I think Joplin like apps suits me better.
    Anyway, good job bringing these nice little pieces of FOSS to our attention. Thanks

  • i have used workflowy and emacs org mode. So i found logseq to be a blend of all these two softwares and has more features. actually it is a blend of a lot of apps. i like using it. there are some bugs considering its stage of development. but still i use it everyday for task management and notes. hope this open source software succeeds as i like the roam of backlinking notes in it.

  • You might find that, on trying to run Logseq as an AppImage (by double-clicking on it after you’ve made it executable), it will simply not run. If you try to run it from the command line:

    $ Logseq-linux-x64-0.5.9.AppImage

    you will probably see this error:

    [15399:0131/235738.544790:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I’m aborting now. You need to make sure that /tmp/.mount_LogseqFIOnLp/chrome-sandbox is owned by root and has mode 4755.
    /tmp/.mount_LogseqFIOnLp/Logseq: error while loading shared libraries: libffmpeg.so: cannot open shared object file: No such file or directory
    Trace/breakpoint trap

    This is because of an improper mode setting of chrome-sandbox within the AppImage. To get around this, run it from the command line this way (without typing the $ prompt):

    $ Logseq-linux-x64-0.5.9.AppImage –no-sandbox
