However, you should still read its licenses and be sure you are using them properly to prevent any future troubles. I’m not responsible of any problems with how you use any of these softwares.
As a new developer, there were many obstacles in my way to create a new an amazing game. One of that obstacles was the lack of money, so in this post I’ll be showing you some of the best softwares I’ve ever used in my developer career and I would’ve liked to know at the start of my journey.
I will try to keep this post updated, if you have any more suggestions please comment below. I do not own the rights or created any of this softwares.
Graphic Design and UI
Probably the first path most developers take is GFX, so here are some softwares that were extremely helpful to me:
Photopea is an extremely helpful software pretty similar to Photoshop and it is completely free. You can save and open your works on PSD (wich is the format Photoshop uses). The only inconvenients I’ve found with this is that every time you save, it creates a new file and since it is web based, the bigger your project the laggier it becomes.
Paint.net is another excellent software used by many clothing designers. In my opinion, it is overrated, but it is helpful for the majority of people.
Gimp is very helpful and easy-to-learn for new artists. Is like an upgraded version of MS Paint.
Inkscape is one of the best alternatives if you want to create vectors (wich are mathematically calculed). Pretty useful for UI designers and artists.
Figma is another excellent option for UI designers. It is free for beginers and offers a lot of options and tools to create amazing and beatiful looking UI for your games.
Krita is a free and open source tool created by artists. It is mainly used to draw, but it might be also helpful ín other ways.
Vectr is a free graphics software used to create vector graphics easily and intuitively. It’s a simple yet powerful web and desktop cross-platform tool
Game UI Database is a website where you can find inspiration for your UI designs. You can filter by type, style and many other filters.
