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.

Tox is easy-to-use software that connects you with friends and family without anyone else listening in. While other big-name services require you to pay for features, Tox is completely free and comes without advertising. Chat, P2P serverless, screen/file sharing, voice, video, groups, encrypted.

GrayJay platform player. I use it for youtube only but it has many sources.

Grayjay enables you to create and watch video content in your own terms, fully retaining ownership and having control over what you watch. Your content on your terms

https://grayjay.app/

https://gitlab.futo.org/videostreaming/grayjay/

(Not to poop on NewPipe, but this app is better in my opinion, I swapped after their player was bugged for me and I got a bit annoyed on the devs response to not adding SponsorBlock (you can say no to a feature ofc, but he decided to add reasoning that was bad))

Is that repo not the code or does it have a (bad) license or something?

[–] chebra@mstdn.io 1 points 56 minutes ago (1 children)

@dogs0n Yeah the license is not open source. It restricts use, modifications and distributions. I thought people in this community would know what the name of the community means.

[–] dogs0n@sh.itjust.works 1 points 51 minutes ago (1 children)

Rip. I had a look and have never heard of their license before.

[–] chebra@mstdn.io 1 points 49 minutes ago (1 children)

@dogs0n There is now a great collection of all of these openwashing cases: https://isitreallyfoss.com/

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.

I love that it has a gender slider

[–] ChaoticNeutralCzech@feddit.org 1 points 2 hours ago

I imagine it affects several parameters that you can also change separately in a CLI, allowing for a multidimensional gender scale.

[–] cyberwolfie@lemmy.ml 1 points 3 hours ago

This looks really cool! Thanks for the share

Logseq: note-taking and knowledge management application that supports Markdown and Org-mode syntax, featuring powerful linking, block-based organization, and full local data storage for privacy

[–] kazerniel@lemmy.world 1 points 58 minutes ago

There's also SiYuan, which is more Notion-like in its functionality, but open source and uses local storage.

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.

tomb: Tomb is a minimalistic CLI based hidden file encryption tool based on Linux dm-crypt and LUKS.
In addition to its cool ass name, it also has a GUI that's called Mausoleum.

ShareX, one of the best Screensho/cast productivity tool, edt tools, OCR, QR codes, scrolling capture, color picker......, storing locally, uploading captures to hosts, sharelink in clipboard. Complement with right click extension for Firefox and Chromium

Sadly Windows only

It's not easy, ShareX depends on NetFramework components, which Linux don't have, it don't even work well with Wine, because of this until now all intents are not very functional or even abandoned (ShareNix (early alpha), ShareXin (archived)....). It's better to use Screenshot tools for Linux, even if they all aren't so complete like ShareX. Architecture differences between Windows and Linux are very big.
