In their own words
HotCRP
HotCRP manages conference paper submissions and reviews, either as open-source software for self-hosting or through the hosted HotCRP.com service. Submission tools include customizable forms, optional registration, program-committee conflict collection, and configurable PDF checks. Papers can be assigned by hand, in batches, or automatically, including through globally optimal assignments. Search, sorting, bulk downloads, formulas, and tags help organize submissions. Review workflows support custom forms, LaTeX math, multiple rounds, offline reviewing, delegation, and external reviewers. Program committee meeting tools include rebuttals, votes, rankings, a live tracker, decision types, and mailing users. The REST API uses bearer tokens that can be scoped, including for read-only access or selected papers. HotCRP.com connects with ACM publication services for copyright forms, final versions, PDF checks, proceedings, and Digital Library export. Self-hosting requires a web server and software including Nginx, PHP 7.3 or higher, MariaDB, and PHP packages. Listed free plans serve certain sponsored events and classroom use; independent conferences pay $7.50 per submission after the deadline.
