Kind is a minimal proof language and proof checker based on dependent type theory and lambda calculus, rewritten from JavaScript to Haskell. It is invoked via the 'kind' command-line tool to type-check and run proof terms, and is part of the Higher Order Company ecosystem alongside HVM and Bend.
Use cases
- verify mathematical proofs with a lightweight proof assistant
- write and type-check programs with dependent types
- experiment with lambda calculus and type theory terms
- learn proof techniques in a minimal proof language
- formally verify functional programs
- prove theorems without heavyweight proof assistant tooling
When to choose
- you want a minimal, easy-to-grasp proof checker instead of heavyweight assistants like Coq, Lean, or Agda
- you want to learn dependent type theory and lambda calculus through hands-on proof writing
- you are working within or exploring the HVM/Bend formal ecosystem
- you prefer a simple command-line workflow for checking and running proof terms
When to avoid
- you need a mature proof assistant with large standard libraries, tactics, and IDE integration
- you need a general-purpose programming language with a rich ecosystem for production software
- you require extensive documentation and long-term stability guarantees
- you need interactive theorem proving with automation beyond simple type checking
