Experimenting with bounties!

We just added bounties on long standing macOS and Windows issues. I have no idea if it will work out but we hope it may be a way to fix these long standing issues!

You can read about our approach to bounties here: f3d.app/CONTRIBUTING.html#boun

If you are interested, do reach out on discord!

F3D is now sponsoring some of the projects we rely on!

⛴️ Exhibit: 5$/month: Because we love that Nokse is sharing F3D with other communities! (github.com/Nokse22)

🖼️ Dear ImGui: 4$/month: Because without it we would not have a nice UI (lnkd.in/ez4KYheh)

⚙️ nlohmanjson: 1$/month: Because json parsing is essential in F3D design (lnkd.in/egq73YpD)

Please do not forget to sponsor the tools you use, this is how open source project thrive! 🙂

See you there I hope 🙂

@backintime I'll be at 2025 and hope to be at 2026.

Hey @backintime

It's funny that we cross paths on reddit and on github many times, despite our respective projects being quite different.

It looks to me that we have a similar approach to open source community and end up with similar problem.

Wanna discuss about it sometimes ?
