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!

Breakout71

I could not believe I didn't find this fun free gem sooner. I'll let the description from F-Droid explain the details:

This is a roguelike twist on the original Breakout formula: The goal is to catch as many coins as possible during 7 levels. Coins appear when you break bricks. They fly around, bounce and roll, and you need to catch them with your paddle. At the end of the level, you get to pick upgrades. There are 50+ different upgrades that impact the gameplay in various ways. Many upgrades will impact your combo, that's the number of coins spawned for each brick broken. Your "combo" is displayed on your paddle. Your score is displayed in the top right corner of the screen. Oh, and don't miss the ball, you don't have extra lives.

I think android HealthConnect doesn't get enough notice as it is a kind of silent background service.

It is local, opt-in, and privacy respecting connection API for sharing data between fitness apps with fine control over what gets shared where. You can have the shittiest privacy-violating fitness app and it can't just steal all of the data from your smartwatch or whatever because you connect the two apps via a stupid cloud integration.

MakeHuman is a 3D character creation software designed to simplify the creation of virtual humans through a graphical user interface. The software allows users to create realistic human characters by adjusting parameters like gender, age, height, weight, and ethnicity through slider controls. Characters can be customized with clothes, hair, poses, and materials from the built-in library and exported to 3D soft, like Blender.

Subsurface

I recently found out after creating Linux, Linus Torvalds wanted to make a good open source scuba dive log software. Today, it's probably one of the best, if not the best dive log programs out there and I recently used this myself on a recent dive and it's great.

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.

FanControl: superb PC fan manager with custom temperature/fan speed curves and the options to combine sensors whatever way you like

OsmAnd: This map application is popular enough that it probably doesn't need mentioning, but good golly is it a powerful tool. Great options for downloading maps and having them offline, and while the car navigation might be missing one or two key features that you'd expect from proprietary alternatives (like live traffic), the sheer amount of detail that has been crowdsourced is mindblowing. There are a wealth of trails and cycle routes, low level details like park benches, bridges, and lookout spots, and the various map profiles you can build are very customizable. I'm personally a huge fan of the trip recording plugin for tracking all my hikes, runs, bike rides, canoe trips, and even swims.

Learned about the mentos thing in 2006. Saw a list of things to flavor coke. This was #4 on the list and I decided to try it (yay mint coke) - at a dollar tree parking lot, in my car. Went off in my mouth and I maintained the pressure until I got the door open and my head out. Thankfully little mess on me or the car. Learned the internet can be full of sneaky assholes that day.
