Everything an event programme team needs

One tool from open call to closing the loop with speakers — self-hosted on your own Supabase project.

Form builder + public CFP

Drag-to-reorder question builder with conditional rules, required-field toggles, and a public call-for-speakers page with deadlines and draft submissions.

Review pipeline & track-routed evaluations

A full submission status pipeline, plus a passwordless evaluator view with track-based reviewer routing and optional blind review.

Drag-and-drop agenda

Build the schedule with an unscheduled-sessions tray, day/room/list views, and advisory conflict warnings for time, room, and speaker clashes.

Speaker portal with magic links

Speakers sign in with a one-link magic link — no password — to check status, edit their profile, and complete assigned tasks.

Communications + real .ics invites

Templated accept/decline emails with a preview-as-recipient step, task reminders, and calendar invites with proper SEQUENCE updates when details change.

Public embeds + JSON/iCal feeds

Drop-in schedule grid and speaker wall embeds, plus a public JSON schedule feed and a whole-event iCal export for anyone building on top.

Dashboard

An at-a-glance view of submission volume, review progress, and outstanding speaker tasks for the whole event team.

Airtable sync (optional)

Mirror submissions to and from an Airtable base for teams whose ops already live there — fully optional, off by default.

Five public widgets, zero logins

Every published session and speaker, rendered as embeddable public pages anyone can browse — and organizers can drop into any website from the admin’s Widgets & Embeds area.
