IsaMorph is a linux distribution Live CD (based on Morphix) featuring the interactive theorem prover Isabelle. This means, you can boot from the CD and get a fully operational "theorem proving" environment without installing GNU/Linux or Isabelle. Just insert the CD in your PC and have five...

The Archive of Formal Proofs is a collection of proof libraries, examples, and larger scientifc developments, mechanically checked in the theorem prover Isabelle. It is organized in the way of a scientific journal. Submissions are refereed. Platforms: *nix

ACL2 is a programming language in which you can model computer systems and a tool to help you prove properties of those models. ACL2 stands for "A Computational Logic for Applicative Common Lisp". It is an "industrial-strength" version of the NQTHM or Boyer/Moore theorem prover, and has been... Platforms: *nix

JGEX, which is actually short for Java Geometry Expert is an ongoing developing system. JGEX is a useful system that is able to combine an approach for visually dynamic presentation of proofs (VDDP), dynamic geometry software (DGS) and automated geometry theorem prover (GTP) . Platforms: Windows

VCC is a mechanical verifier for concurrent C programs. VCC takes a C program, annotated with function specifications, data invariants, loop invariants, and ghost code, and tries to prove these annotations correct. If it succeeds, VCC promises that your program actually meets its specifications.... Platforms: Windows

Tabular Expression ToolboxTabular Expressions (also called "tables") provide a precise and concise way to represent mathematical conditional expressions. Tables have been shown to be useful in the documenting and analysing of software systems. The graphical layout of tabular expressions allow for... Platforms: Matlab
