Some of the tools listed here are part of bigger projects that support other proof assistants/theorem provers. Another list of Coq-related tools can be found at

Interface for Editing Proofs

  • CoqIDE

    The graphical user interface distributed with Coq.

  • ProofGeneral

    ProofGeneral is a generic interface for proof assistants, based on the customizable text editor Emacs.

  • Coqoon

    Eclipse plugin for Coq development (based on Wenzel's asynchronous PIDE framework).

  • ProofWeb

    An online web interface for Coq (and other proof assistants), with a focus on teaching.

  • vscoq

    A Visual Studio based interface developed in 2016.

  • jscoq

    A port of Coq to the browser; runs standalone using js_of_ocaml.

  • CoqTail

    CoqTail is a vim plugin aiming to bring the interactivity of CoqIDE into your favorite editor.

Language Servers

  • coq-serapi

    A language-server based in the STM protocol with full serialization capabilities [proofs, documents, terms].

Discontinued interfaces

  • Coq PIDE

    Jedit (proof of concept) plugin for Coq development by Carst Tankink (also based on asynchronous PIDE framework).

  • ProverEditor

    An experimental Eclipse plugin with support for Coq.

  • tmEgg

    Coq plugin for TeXmacs

  • Papuq

    Papuq is patched version of CoqIde with teaching oriented features.

  • GeoProof

    GeoProof was a dynamic geometry software, which can communicate with CoqIDE to build the formula corresponding to a geometry figure interactively.

  • PCoq (for versions of Coq in old syntax, version 7.4 of 2003 and before)

    A graphical user interface for Coq. The environment provides ways to edit structurally formulas and commands, new notations can easily be added. It allows proof by pointing.

  • TmCoq

    TmCoq integrates Coq within TeXmacs.

Interface for Browsing Proofs

  • Helm is a browsable and searchable (using the Whelp tool) repository of formal mathematics (includes the Coq User Contributions).

Presenting Proofs

  • coqdoc exports vernacular file to TeX or HTML. It is part of the Coq distribution and documented in the Reference Manual.

Tactics packages

  • Micromega: solves linear (Fourier-Motzkin) and non linear (Sum-of-Square's algorithm) systems of polynomial inequations; also provides a (partial) replacement for the Coq's omega tactic.
  • Ssreflect facilitates proof by small scale reflection, "a style of proof that ... provide[s] effective automation for many small, clerical proof steps. This is often accomplished by restating ("reflecting") problems in a more concrete form ... For example, in the Ssreflect library arithmetic comparison is not an abstract predicate, but a function computing a boolean. (source)"
  • AAC Tactics provides tactics that facilitates the rewriting of universal equations,modulo associative and possibly commutative operators, and modulo neutral elements (units).

Packaging extracted code

  • Z_interface An approach for deriving directly standalone programs from extracted code.


  • coqwc is a stand-alone command line tool to print line statistics about Coq files (how many lines are spec, proof, comments). coqwc comes with the standard Coq distribution.

  • coq-tools is a collection of scripts for manipulating Coq developments:

    • is a "bug minimizer" that automatically minimizes a .v file producing an error, allowing automatic creation of small stand-alone test cases for Coq bugs;

    • processes .v files, replacing things like Require Import Program. with Require Import Coq.Program.Program., making Requires robust against shadowing of file names;

    • inlines the Required dependencies of a .v file, allowing the automatic creation of stand-alone files from developments;

    • removes unused Require and Require Import statements, and, optionally, unused Require Export statements;

    • splits all Require Import and Require Export statements into separate Require and Import/Export statements, and moves all Require statements to the top of a .v file;

    • lifts many vernacular commands and inner lemmas out of Proof. ... Qed. blocks;

    • processes the output of running coqc on a file with Suggest Proof Using set, to modify the file with the given Proof using suggestions;
