Who are we?
A small group of Delft parents who got tired of wrestling with the pool's booking site, so we built something that shows which lessons have places — all on one page — and decided to share it.
What this is — and isn't
This page is not run by Sportfondsen, the swimming pool, or the municipality. It is an unofficial overview built from the pool's own public booking pages, and it can be wrong or a little behind. The webshop is always the source of truth — always book there; nothing is ever booked or reserved through this site.
How it works
A small program looks at the pool's public booking pages a couple of times an hour during the day, one page at a time and slowly, so we never burden their website. It writes down what it finds — which lessons have places, when, and how long the waiting lists are — and shows it here. Parents who want to can also set it up to get a phone alert when a place comes free.
What we don't do
- No accounts, no logins, no passwords — there is nothing to sign up for.
- No cookies. We use Vercel's built-in visitor statistics to see roughly how many people use the page; they don't identify you, and nothing is stored about you or your child.
- No booking on your behalf. We only show you where to look.
Free, and made in our spare time
This costs nothing and promises nothing. If a number looks odd, tap the lesson name — it opens the pool's own page with the real, up-to-the-second figure. If something could be better, please tell us: your suggestions go straight to the parents who maintain this.
Voor Nederlandse ouders
Zwemles Radar wordt gemaakt door een paar ouders uit Delft en is niet verbonden aan Sportfondsen. We tonen de plekken en wachtlijsten van de openbare boekingspagina's van het zwembad; boeken doe je altijd in hun eigen webshop. Geen accounts en geen cookies; we tellen alleen anoniem hoeveel bezoekers er zijn. Suggesties zijn welkom via het formulier.
