leanprover/Pantograph
(Mirror) A Machine-to-Machine Interaction System for Lean 4
Pantograph provides a way for other computer programs to interact with Lean 4, a formal proof assistant. It lets external systems submit mathematical proofs or expressions to Lean, execute them, and receive feedback about the Lean environment. This is for developers building tools or integrations that need to automate interactions with Lean 4.
Use this if you are a developer creating applications that need to programmatically control or query Lean 4.
Not ideal if you are a Lean user who wants to write proofs directly or are looking for a graphical user interface.
