Summary
HotCRP manages conference paper submissions and reviews, either as open-source software that users host themselves 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 manually, in bulk or automatically, including through globally optimal assignments. Search and sorting by criteria, bulk downloads, formulas and tags support paper management. Review workflows can use custom forms, LaTeX math, multiple rounds, offline reviewing, delegation and external reviewer invitations. Program committee meeting tools include rebuttals, votes, rankings, a live meeting tracker, custom decision types and mailing users. The REST API uses bearer tokens with scopes that can be limited, including read-only access or access to selected papers. HotCRP.com connects with ACM publication services for copyright forms, final versions, PDF checks, proceedings construction and Digital Library export. Self-hosting requires a web server and software including Nginx, PHP 7.3 or higher and MariaDB. Free plans are listed for some sponsored and classroom uses; independent events pay $7.50 per submission after the deadline.
