👋 We are Obsidian Systems

We're a software consultancy specializing in building great products on technologies that promote quality and rapid iteration. Check us out at https://obsidian.systems

Welcome to our github page. Here you'll find some of our open source work, primarily in Nix, Haskell, and Rust.

We're the primary authors and maintainers of:

  • reflex-frp, an ecosystem for functional reactive programming
  • obelisk, a framework and tool for full-stack Haskell applications
  • alamgu, an ecosystem for building hardware ledger applications

We do a lot of open source work, so we've tried to organize the repos below:
