Graphical Unix-like operating system for x86 computers.

I always wondered what it would be like to write my own operating system, but I never took it seriously. Until now.

Serenity is a love letter to '90s user interfaces, with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by me, for me, based on the things I like.

If you like some of the same things, you are welcome to join the project. It would be great to one day change the above to say "this is a system by us, for us, based on the things we like." :^)

I regularly post raw hacking sessions and demos on my YouTube channel.

There's also a Patreon if you would like to show some support that way.

• Pre-emptive multitasking
• Multithreading
• Compositing window server
• IPv4 networking with ARP, TCP, UDP and ICMP
• ext2 filesystem
• Unix-like libc and userland
• Shell with pipes and I/O redirection
• mmap()
• /proc filesystem
• Local sockets
• Pseudoterminals (with /dev/pts filesystem)
• Event loop library (LibCore)
• High-level GUI library (LibGUI)
• Visual GUI design tool
• PNG format support
• Text editor
• IRC client
• DNS lookup
• Desktop games: Minesweeper and Snake
• Other stuff I can't think of right now...

Go into the Toolchain/ directory and run the BuildIt.sh script. Then source the UseIt.sh script to put the i686-pc-serenity toolchain in your $PATH.

Once you've done both of those, go into the Kernel directory, then run makeall.sh, and if nothing breaks too much, take it for a spin by using run.

Otherwise, see the older step-by-step guide to building Serenity
