Instead of HotCRP

HotCRP alternatives

HotCRP centers on scholarly conference review, from configurable submissions and conflict collection to PDF checks, reviewer assignment, searchable papers and tagged decisions. Its review tools cover multiple rounds, offline work, delegation, external invitations, rebuttals and program committee voting. Organizers can use the hosted service or self-host the open-source software with Nginx, PHP 7.3 or higher, MariaDB and related PHP packages. A scoped REST API and ACM publication-service integration extend its workflow.

Alternatives become relevant when a conference needs event operations beyond paper review, such as registration, ticketing, payment processing, public programs, mobile apps or virtual sessions. HotCRP's Independent plan costs $7.50 per submission, payable after the submission deadline, while support for independent sites is limited to bug fixes and classroom use has no support. Compare each option's review model, scheduling and attendee tools, integrations, hosting approach, platform coverage and pricing structure before switching.
