In their own words
OpenSession
OpenSession is a free, MIT-licensed platform for managing conference programs from proposal intake through speaker onboarding and agenda publication. Organizers create call-for-papers forms with MDX, conditional logic, multiple speakers, and file uploads; each speaker may submit up to three talks per event. Reviewers can vote, comment, and view aggregate scores without administrator access. The agenda builder assigns accepted sessions to rooms and time slots while flagging room and speaker conflicts. Schedule changes automatically update RFC 5545 ICS invitations. Accepted speakers receive a self-service portal for profiles, submissions, onboarding tasks, and files. Organizers can publish embeddable agendas and speaker galleries, plus JSON and ICS feeds. The software can be self-hosted on Cloudflare Workers, using D1 for its database and R2 for files. The listed plan is free, billed free forever. Cloudflare’s listed free-tier limits are 100,000 requests daily, 5 GB of D1 storage, and 10 GB of R2 storage. It does not cover CRM, marketing pages, or payment processing.
