We all love open-source software, but there are so many amazing projects out there that often go unnoticed. Let's change that! Share your favorite open-source software that you think more people should know about. Here’s how you can contribute:

  1. Single Option Per Comment: Mention one open-source software per comment to be able to easily find the most popular software.
  2. No Duplicates: Avoid duplicating software that has already been mentioned to ensure a wide variety of options.
  3. Upvote What You Love: If you see a software that you also appreciate, upvote it to help others discover it more easily.

Check out last year's post for more inspiration: Last Year's Post

Let's create a comprehensive list of open-source software that everyone should know about!

PairDrop like Localsend or Airdrop but working on anything that has an internet connection and a resonably new web Browser! You can share files even when on different networks, by pairing devices. Works like a charm.

OsmAnd, mobile app for navigation and maps. Offline, based on OSM, can do anything. I use it for checking out and bookmarking places, finding POIs and pubic transport stations, routing (especially for bike and foot), measuring distances, and so on. It can also show and record tracks, do car navigation, edit OSM points, and more stuff that I don't use. Pro/plus/full version free on FDroid

krusader is a dual-paned file manager for KDE. It runs on Linux (of course), MS Windows, and Mac OSX.

Folder sync is what makes krusader outstanding, even if you don't care about dual-pane file management. Open the two folders you want to sync in the panes and go to Tools > Synchronize Folders. You can synchronize both ways, exclude files, delete lone files, etc. Very powerful.

Being a KDE app, krusader does not skimp on features, so there are lots of other things that krusader can do.
