OpenReview vs Sessionize

OpenReview is a configurable web and API platform for peer review and scientific communication. Venues can track submissions and coordinate authors, reviewers and editors through multiple review stages. Organizers configure review forms, permissions and timing, while accepted papers can retain reviews, comments and ongoing discussion. Reviewer-paper matching can use expertise, bids, constraints and reviewer balancing. Venues may enable real-time committee chat on paper forums; messages are hidden from authors and the public by default. The REST API covers records, groups, documents, invitations, assignments, conflicts and workflow automation. OpenReview’s web interface is free software under the GNU Affero General Public License v3, and other platform components are also open source. Its free plan provides free paper access and submissions with no fees. Organizers request a venue through a support form, then the OpenReview team reviews and deploys it. For venues with separate track deadlines and review forms, organizers are instructed to request a separate venue for each track. General inquiries use the support form.

Sessionize is cloud-based event content management software for organizing in-person or online events. Its workflow covers calls for speakers, proposal evaluation, speaker and session management, and schedule building. Organizers can create submission forms with custom fields, submission limits, deadlines, and agent mode. Evaluation options include star ratings, Yes/No decisions, and comparisons. Schedules can be arranged by drag and drop, embedded on websites, or retrieved as JSON or XML. The included attendee app works on phones, tablets, and desktops, supports offline use, and lets attendees build personal schedules. API integration and embedding support event websites, mobile apps, and WordPress sites. Sessionize lists unlimited sessions, speakers, team members, organizers, and evaluators. Its free trial requires no credit card. Community events can use the free plan, while a Professional event costs $499, paid once for one event occurrence. Sessionize does not provide attendee management or ticket selling, live streaming or video hosting, or an event webpage builder. It is available on Android, iOS, and web.
