Greenroom review
A broad, self-hostable workspace covering speaker management from CFP to publication.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Greenroom is an open-source conference program platform for organizers managing speakers from call for speakers through publication. It combines application forms, blind review, speaker status tracking, onboarding tasks, agenda building, communications, and publishing in an event workspace. Speakers can submit talks, update profiles, and follow their status through a portal, while organizers manage reviews, scheduling, confirmations, feedback, reminders, and calendar invitations. It is aimed at teams that want end-to-end control and the option to self-host.
Platform fit is a central strength. Greenroom offers web access, a REST API for sessions, submissions, and speaker profiles, signed webhooks for submission events, embeddable public widgets, and one-way Airtable synchronization. The organization-wide speaker database adds sourcing pipelines, segments, merge tools, and bulk outreach, giving recurring event teams a way to retain speaker relationships beyond a single program. Airtable is the listed external integration, while the API and webhooks provide paths for connecting other internal systems.
The product’s breadth makes it suitable for teams coordinating complex speaker programs rather than only collecting applications. Its form builder supports custom fields, conditional logic, tracks, close dates, and submission limits; blind review includes weighted scorecards and reviewer assignment; and the drag-and-drop agenda builder includes conflict detection. The tradeoff is operational scope: smaller teams seeking a simple CFP form may not need a full speaker database, communications workflow, and scheduling layer. Teams choosing Greenroom should be comfortable with an open-source, self-hostable product and its deployment responsibilities, while organizations wanting a narrow hosted tool or a wider prebuilt integration catalog should consider alternatives.
