TLA+ is a formal language for specifying systems that is used in academia and industry. Tool support for TLA+ is provided through the TLA+ Toolbox, an Integrated Development Environment for writing TLA+ specifications and analyzing them using the TLA+ tools. The tools include the TLC model checker, the PlusCal algorithm language and translator, and the TLA+ Proof System.

Members of the TLA+ community exchange online via the TLA+ Google group. The TLA+ Community Meeting is intended as a forum where practitioners and researchers interested in the use and further development of the TLA+ specification language and its associated tools meet and discuss. The 2018 meeting consisted of tutorials that presented recent developments concerning the TLA+ language and tools, and of contributed talks.
