AProVE is a system for automated termination and innermost termination proofs of term rewrite systems (TRSs). Moreover, AProVE also handles several other formalisms, e.g., logic programs (Prolog), functional programs (Haskell 98), conditional TRSs, TRSs modulo AC, context-sensitive TRSs, etc. The power of AProVE is demonstrated in the annual International Competition of Termination Tools, where AProVE was the most powerful tool for termination of TRSs in 2004, 2005, 2006, 2007, and 2008.

The Tyrolean Termination Tool 2 (TTT2) is a tool for automatically proving (and disproving) termination of rewrite systems. It is the completely redesigned successor of TTT. Current (non-)termination techniques include approximated dependency graph, argument filtering, bounds, dependency pair method, Knuth-Bendix order, lexicographic path order, loop detection, matrix interpretation, polynomial interpretation, predictive labeling, recursive SCC, root labeling, semantic labeling, simple projection and subterm criterion, uncurrying, usable rules.

The Nagoya Termination Tool (NaTT) is a termination prover for term rewrite systems (TRSs), which is special for: its power due to the implementation of the weighted path order (WPO), its efficiency due to the strong cooperation with external SMT solvers, and use of the DP framework for proving relative termination

TRS.Tool is a teaching-oriented tool that can be used to learn the basic notions and concepts of term rewriting. Accordingly, it gives a lot of explicit and intermediate information about signatures, terms, positions, rules, and term rewriting systems, and also about the analysis of critical pairs. We hope that this approach will be useful to get undergraduate students (and interested people) familiarized with the basic rewriting theory and then become involved in the field.

By this tool proofs of (relative) termination of string rewriting systems (SRS) can be generated automatically. It was developed by Hans Zantema starting in July 2003. It is based on a combination of polynomial and matrix interpretations, recursive path order, semantic labelling, dependency pairs, transformation order, dummy elimination and RFC-match-bounds. Proofs of non-termination are found by using ancestor graphs. In both the termination competition of 2004 and the termination competition of 2005 this tool performed the best of all tools in the category of string rewriting.

Vienna Modular Termination Laboratory (VMTL) is a tool for the (semi-)automatic termination analysis of rewriting systems. Currently, standard as well as context-sensitive and conditional term rewriting systems are supported. VMTL is an implementation of the dependency pair framework, in which termination of rewrite systems is analyzed by so called dependency pair processors. The search for termination proofs in VMTL is guided by a user configurable strategy featuring hierarchical grouping of processors, time-limits on the level of processor groups as well as single processors and parallelization. In addition VMTL provides open interfaces allowing to add new dependency pair processors as well as transformations/preprocessings of rewrite systems in a modular fashion.
