Here is a collection of all the software, sites and other stuff I use on a daily basis. Also I have added Discord Client since this entire website is themed around it (and because I use it everyday). Most if not all are free and open-source.

Software

- Paint.NET

Paint.NET is a free image and editing program. Although not a 1 to 1 copy of Photoshop and not as versatile, its still very good for what it is.

- Everything

Everything is a free tool to find any file from anywhere on your computer.

- Audacity

Audacity is a free audio editing and mixing tool. Often used by various content creators.

- Notepad++

Notepad but better! Saves currently opened files even when closing the program.

- Krita

Very good art program, I personally don't use it but a lot of my friends do. Both on Windows and Android.

- Greenshot

Awesome screenshot tool with support for various image hosting sites (Flickr, Picasa, Imgur), various export options etc.

- Handbrake

Convert any video type into any other one for various platforms. Free and open-source.

- MusicBee

MusicBee is a free music player with support for Last.fm and Soundcloud. Syncs across devices and highly customizable.

- Parsec

Parsec is a remote desktop software that allows your friends to connect with your computer and play local play only games.

- Playnite

Playnite is a free and open-source videogame library manager. You can import your libraries from Steam, Epic Games and more. Also provides emulation.

- FlashPoint

Used to replay old flash games ever since Adobe Flash got discontinued.

Websites

- Photopea

Photopea is the best free online alternative to Photoshop. You probably already know that since it's been recommended to hell and back.

- HexEdit

Online hex editor, similar to HxD.

- dCode

Online decypher tool for messages, cheats for puzzles, letter games, geochaches.

- doodad.dev

Cool website with tools such as Dither Me This, Pattern Generator and Not Another Gradient Generator. Very useful.

- Lycanroc.net

Another cool website with lots of tools, games etc. Most importantly features deprecated tools no longer available for download, older versions of software and hard-to-find apps. Also features soundfonts, and programs made by them.

- Video Game Music

Hosts music from almost every videogame you can think of.

- VG Resource

Hosts the Spriter's Resource and the other sites. Very useful if you need any sprite, model or music file from any game.

Discord Clients

Discord Clients are against Discord's TOS. Use at your own risk.

- Powercord

A more simple and lightweight Discord client. Although provides little to no customization/plugins. Desktop only.

- BetterDiscord

The most popular and arguably best Discord client. Tons of customization, themes and plugins. Desktop only.

- Vencord

My personal favorite, Vencord is just like BetterDiscord but works on browser too. Comes with pre-built plugins and support for BetterDiscord themes. Has a mobile version, but is not recommended.

- Vendetta

Another client I use. Vendetta is based on the newer versions of discord, is lightweight, with tons of customization. Mobile only (Android & iOS). Support and further development has stopped.

- Aliucord

Aliucord is based on the older versions of discord. No root needed, with an in-app updater.
