The event queue tool that doesn't melt under load
Live events break cloud-first software. The festival ground floods every nearby cell tower. The convention center basement has Wi-Fi that drops every fifteen minutes. The wedding venue is in the woods. Waitlist App is built to keep working when the network does not — because the entire app runs on your device, with optional cloud sync layered on top when you actually have signal.
Where it fits in the event flow
- Registration line. Walk-ups, will-call, badge pickup — track every attendee, send a notification when their badge is ready.
- Vendor & expo halls. Demo booths with capacity limits use the waitlist plus tally counter to manage turn-by-turn access.
- Breakout sessions. Reservation view manages limited-seat workshops; waitlist captures overflow.
- Wedding receiving line. Yes, really — the host stand model maps perfectly to a wedding planner managing arrivals.
- Coat check, food trucks, restrooms. Anywhere humans wait, this works.
Why offline-first matters for events
The single largest cost of cloud-based queue tools at live events is invisible until showtime: when the venue's connectivity degrades, the tool stops working — and your line collapses into chaos exactly when you have the highest stakes. Waitlist App's service worker caches the entire app shell locally on first load. Customer data lives in browser localStorage. The app does not need the internet to add an attendee, calculate wait times, or trigger SMS via the device's native messaging app.

Multi-station setups
Most large events run multiple registration lanes simultaneously. The free tier works perfectly for each independent station. If you need a single shared queue across all lanes — so attendee #234 at the right registration desk doesn't get accidentally assigned to lane 3 — that's the Pro tier with multi-device sync. Set up a tablet at each station, and they all see the same live waitlist.
Frequently asked
How many attendees can it handle?
The free tier comfortably handles thousands of waitlist entries per session on a single device. localStorage limits are typically 5–10 MB per origin, which is enormous for queue data.
Can attendees check their position from their phone?
The Pro tier exposes a public tracking link per attendee (the /q/{token} flow). The free tier is staff-facing.
Can we brand the registration lane experience?
The Developer tier ships embeddable queue widgets for your event microsite, with HMAC-signed webhooks for downstream automation.
What about the kids' party at our wedding venue?
Honestly, yes. The general-business preset works fine for kids' party check-ins, RSVP tracking, and "please find your table" notifications.
