Sold-out rarely means sold out permanently. Held allocations get released, returns come back, and extra dates are added — usually with no announcement and a window measured in minutes.

How do you monitor ticket availability?
Watch the event page and select whatever indicates availability — a "sold out" label, the ticket type list, or the checkout button. When it changes you get an alert. It works on any public event page, including the many that offer no waiting list at all.
Ticket releases are among the least predictable things on the web. Allocations held back for presales get released quietly, returns reappear when a payment fails, and additional dates go on sale before any announcement reaches you.
Official waiting lists are the obvious answer and a poor one — they notify everyone at once, and plenty of events do not offer them.
Watching the page directly is the alternative. This guide covers what to select, how fast to check, and the ticketing sites where this simply will not work.
Availability is signalled differently by every ticketing platform.
Where a page says "Sold out" or "No tickets available", select that text. Anything replacing it is your alert.
On events with several categories, select the list itself. A new tier appearing, or one becoming selectable, is caught this way.
For runs and tours, watching the list of dates catches an added performance, which is often the easiest ticket to get.
Event pages carry recommendations, countdown timers and "X people viewing" counters that change constantly. Selecting a region removes them, and the pre-check filter removes most of the rest automatically.
Watch the date list as well as the event itself. Added performances are announced less loudly than releases, and are frequently the easier ticket.
Ticketing is one of the harder categories for an external checker, and it is worth saying so plainly.
Major ticketing platforms put everyone through a virtual queue before the real page. There is no stable public page to compare, so this approach cannot help for those on-sales.
Ticketing sites are among the most heavily defended on the web. We identify ourselves honestly rather than disguising the traffic, so a site refusing non-browser clients will refuse us.
Common on modern ticketing platforms. Browser rendering on a paid plan handles it, at up to every fifteen minutes rather than every five — which for a fast-moving release may be too slow.
You get an alert. There is no checkout automation, no queue-jumping and no reservation. For a major on-sale, that means you are alerted and then in the same queue as everyone else.
Given those limits, this is where people actually get value.
Returns trickle back at unpredictable times, usually outside an on-sale window and without any queue in front of them. This is the best case for page watching.
Announced quietly, often on the venue page before anywhere else.
Little or no bot protection, no queue system, and rarely a waiting list. Page watching works well here.
Restaurant reservations, course places, workshop slots and similar pages behave the same way and are far less defended.
Get alerted when tickets are released or returned for a sold-out event.
We load it and show it back, so you can confirm availability is visible without a queue in front of it.
Or the sold-out label, whichever actually changes when tickets return.
Returns disappear quickly. Sixty seconds on Pro, five minutes on the $5 plan.
Email is usually too slow for this. Push reaches a phone lock screen.
Added performances are quieter than releases and often easier to get.
The alert is the signal; buying is still yours, and quickly.
Typically about 2 minutes from start to finish.
Uptime monitors, watched pages and heartbeats each get their own allowance, so adding a page watch never costs you a monitor. SSL and domain checks ride along with the monitor they belong to and use nothing extra.
| Plan | Monitors | Watched pages | Heartbeats | Fastest interval | Alert channels | Price |

| Founding Member first 20 only | 25 | 25 | 25 | Every 5 minutes | Email + webhook & chat | $5/mo |
| Basic | 10 | 10 | 10 | Every 10 minutes | Email + webhook & chat | $8/mo |

Annual billing is cheaper on every paid tier. The pricing page is the authoritative list.
Every recorded change is compared word by word and kept with a before-and-after image. This is the real output, shown with worked example data.
Price fell from $49 to $39, and an annual discount was added.
The item is available again and the basket button returned.
A new subprocessor was added in another jurisdiction.
The free plan sends to one email address. Every paid plan adds the chat and webhook channels below, with 2 to 10 destinations depending on the plan. However many alerts you receive, the price does not change — nothing here is metered or charged per alert.
There are no voice calls and no SMS. If a phone call at 3am is a hard requirement, say so before you subscribe — we would rather tell you now than refund you later.
Watch the event page and select the ticket list or sold-out label. When it changes you are alerted, without waiting for a mailing that goes to everyone at once.
Often not for on-sales. The big platforms use virtual queues and heavy bot protection, and there is no stable public page to compare during a queued release. It works far better for returns, added dates and smaller venues.
No. It will tell you a page changed. It does not queue, reserve or buy, so for a big on-sale you are alerted and then in the same queue as everybody else.
Returns on sold-out events, added dates, smaller venues and independent sellers with no waiting list — plus non-ticketing availability like restaurant reservations and course places.
Sixty seconds on Pro, five minutes on the $5 plan, thirty minutes on free. For returns, faster genuinely matters.
Yes, with browser rendering on a paid plan, checked at up to every fifteen minutes rather than every five. For a fast-moving release that may be too slow to be useful.
Select the ticket list rather than the whole page. Countdown timers and "X people viewing" counters are also removed automatically, because anything differing between two immediate loads is excluded before the first check.
Yes — 25 pages on the $5 plan, 50 on Growth, 100 on Pro, all at the same interval with no check quota.
