Not a screenshot — the schedule itself

The demo conference’s published programme, rendering inside this page right now. Real rooms, real talks, real times. Switch the day; click a block. The organizer builds this by dragging accepted talks onto a room-by-time grid, and a clash goes red the moment it lands.

Loading the published schedule…

Every block here is a row in the demo database, served by the same public page an attendee would open — no export step, no copy of the schedule to keep in sync.

Straight to the proof

Everything worth seeing, one click each

Each card opens the running demo on the screen where that thing actually happens — signed in as whoever is allowed to see it. No signup, nothing to set up.

Some are public URLs that need no account at all. The rest sign you into the demo event as the organizer or the speaker — the same logins the sign-in page offers, picked for you so you land on the right screen.

Proposals, reviewers, decisions, speakers, the schedule and the public program — one board.

Speakers you can actually manage

Import the roster, invite people into their own portal, track every upload.

AI speaker research

One click runs a real web search and writes a brief before you decide.

Decisions that send themselves

Accept a talk and the speaker gets the email — and the calendar invite.

Publish the program everywhere

Session, speaker and agenda pages, plus embeds for your own site.

Open source

Yours to run, fork, and self-host

MIT licensed. Read every line, deploy it on infrastructure you control, change what your event needs changed. No per-submission pricing, no seat counts.

View the source on GitHub Try the hosted demo

Self-host it. One repo, one deploy — Cloudflare Workers, D1, R2. Your data stays in your own account.
Bend it to your event. Forms, review criteria, email templates and public pages are configuration — the rest is code you can fork.
Sized for big programs. The load-test seed in the repo (scripts/seed-stress.ts) fills an event with 400 proposals, 150 speakers and 1,200 review assignments. The demo you can click is kept small on purpose — small enough to read.

For organizers

Run the whole event from one desk

Set it up once. Dates, tracks, formats, rooms, the call and its deadline.
See the whole pipeline. Every proposal, with filters that actually filter.
Decide in one click. Emails, onboarding tasks and calendar invites follow on their own.

Submissions pipeline: every proposal with speakers, track, format, and decision status

For reviewers

A review queue that respects your evening

A queue, not a maze. A "next unreviewed" button that never loses your place.
Score on real criteria. Ratings, recommendations, comments — weighted per round.
Blind when it matters. Identities hidden, conflicts of interest recused.

For speakers

Speakers always know where they stand

One link, the whole story. Status, tasks, profile — no email archaeology.
Never a black hole. Submitted → In review → Decision → Scheduled.
Uploads where they belong. Slides and headshots land on the talk, not in a thread.
