Free (libre) software replacements for proprietary software

Just needs a cross platform syncing app

(i haven't seen it mentioned in this sub. it has improved quite a bit since its inception. it deserves some credit🥂)

Jami is a free/libre, end-to-end encrypted and private communication platform that requires no central authority.

Multiple devices can be linked to a Jami account, and no personal information is required to create an account.

What features does Jami include?

• Instant messaging
• Audio and video calls
• Swarms (group chats)
• Video-conferences and Rendezvous points with no third-party hosting
• Audio and video message recording
• Screen sharing and media streaming
• Built-in extension platform for new features and experiences
• Jami can also function as a SIP client

Jami uses a distributed hash table (DHT) to connect peers. Jami accounts are asymmetric X.509 certificates generated by the GnuTLS library. Calls are made over the Session Initiation Protocol (SIP) after negotiating a TLS-encrypted secure connection, performing Secure Real-time Transport Protocol (SRTP) communication which carries the media streams.

Alternativeto is not itself FOSS or anything, but it's nonetheless a handy tool for finding open alternatives for proprietary software & services.

There's an Open Source filter under Licenses.

I've found a lot of good stuff there.

Intrigued by the fact that many Bibliogram/Nitter/Invidious/Piped instances are from sites that also offer other services, I set out with good will to sift through them one by one, and here are the results (and I must say I discovered many instances that are not indexed on the "official" directories).

Obviously if I missed any I will point them out and add them.

Open Webinar, 19 January 2022 at 10.00 UTC+1

What if you could easily collaborate with any free software project, no matter where it is hosted? Use the Github UI to discuss issues on a remote Gitea code forge project. Send a Merge Request from Gitlab to Github. Have you and your team members, all your project contributors, everyone working from their own favourite environment. Use your code forge of choice to collaborate. Just like you also freely choose your email provider to communicate with others.

This is the objective and vision that the forgefriends community is working hard to realize. Its members, all forge friends, strive to allow seamless interoperability between code forges by adding federation support. Using the Fediverse and open standards such as ActivityPub and DVCS they will enable free software development to liberate itself from centralized platforms that lock projects in with their network effects and FOMO.

In this webinar you will learn about the importance of forge federation, and what it means to be "a friend of code forges". The various community projects are introduced, with brief explanation how they work and what is on the roadmap. Anyone is highly encouraged to contribute and become a forge friend too. Each presentation is followed by a Q&A session where you can ask the presenter how you can jump in.

Is there any FOSS to manage subscriptions? My particular need is to trigger an API call upon subscription to start the service, and then bill subscribers based on their usage. The service would report the usage to the subscription manager.

It would be awesome if the manager also provides a user area for subscribers to manage their subscription, pay bills and change a few settings, create support tickets, etc.

Any FOSS alternatives to MS Paint? Krita and Glimpse are quite sophisticated, so maybe something simple to just use in a pinch.

I just made this video about why Lemmy is an awesome alternative: https://tilvids.com/videos/watch/eed58554-8c27-47fe-b83a-53cbe6f612e6

Does anyone know a foss alternative to unsplash?

I've noticed question2answer (https://alternativeto.net/software/stackoverflow/?license=opensource) as a first alternative, but I don't know how to find instance of it focused on programming. There's a list on their webiste, but very few instances are listed there.
Does anybody know about some libre alternative to Stackoverflow?

Not sure if this is the right place for this but I want to buy a domain and I would like to support floss if that is even a thing for domains.

I am looking for a website similar to Privacytools, Prism Break, Ethical.net or switching.software but more focused on freedom than privacy, presenting the best replacements for proprietary programs in the desktop and mobile. Is there anything like that?
