Integrated Tests Gitter chat

Resea [ríːseə] is a microkernel-based operating system written from scratch. It aims to provide an attractive developer experience and be hackable: intuitive to understand the whole design, easy to customize the system, and fun to extend the functionality.

See Documentation for more detials.

Features

  • A minimalistic and policy-free microkernel based operating system written entirely from scratch in C (and less than 5000 LoC). Everything is message passing!
  • Supports x86_64 (with SMP) and 64-bit ARM (Raspberry Pi 3).
  • Includes userspace servers like TCP/IP protocol stack and FAT file system driver.
  • Provides easy-to-use APIs and every components are written in single-threaded event-driven approarch. It makes really easy to understand how Resea works and debug your code.
  • Some attractive experimental features like Linux ABI emulation, Rust support, and Hardware-assisted Hypervisor (like Linux's KVM).

See Road Map for planned new features and improvements.
