Develop Gleam applications on the BEAM with advanced skills for OTP actors, Erlang interop, and type-safe programming, plus a language server for code intelligence and automated logging of file writes and web fetches.
Use when oTP actor patterns in Gleam including processes, message passing, GenServer implementations, supervisors, fault tolerance, state management, and building concurrent, fault-tolerant applications on the Erlang VM.
Use when gleam-Erlang interoperability including calling Erlang code from Gleam, using Erlang libraries, external functions, working with Erlang types, NIFs, and leveraging the BEAM ecosystem from Gleam applications.
Use when gleam's type system including algebraic data types, custom types, pattern matching, generic types, type inference, opaque types, exhaustive checking, and functional error handling for building type-safe Erlang VM applications.
Ship-ready code from your AI coding agent. 139+ plugins for quality gates, tooling, memory, and specialized agents — so your AI writes code that's ready to merge.
Two commands. That's it.
# 1. Install the CLI
curl -fsSL https://han.guru/install.sh | bash
# 2. Auto-detect and install plugins for your project
han plugin install --auto
Next time you use Claude Code, validation hooks run automatically when you finish a conversation.
# Homebrew (macOS/Linux)
brew install thebushidocollective/tap/han
