A prefecture appointment alert does not book on your behalf. It monitors a public calendar and tells you when a date appears. Comparing these services means checking their prices, coverage, channels, and what their public pages actually allow us to verify.
What a good alert service should do
Monitor, alert, never book on your behalf
Start with what to do when no appointment slot is available. Then select a prefecture and process. The service checks the official page and sends a link when it detects availability. You then book the appointment yourself. An alert is a legal alternative to appointment resale. It should never sell the appointment, request your government account password, or guarantee a particular date.

We checked homepages, likely pricing paths, and legal pages using curl requests with redirects enabled. We made no purchase and created no account. Phrases such as "instant" or "under 60 seconds" are therefore provider claims, not independently measured performance.

Why Alertes Préfecture is not in the table
How to read prices and claims
Pricing that's not always easy to compare
RDVHub published no usable amount on the tested public pages, so its price must be checked during subscription. MonRdvPréfecture displayed two plans: Premium at €9.90 per month for one alert and Pro at €29.90 per month for unlimited alerts. Its legal notice named DassIT as the publisher.
What no tool can guarantee
No tool can guarantee that a prefecture will release a slot. Continuous 24/7 monitoring describes an operating period, not a precise interval between checks. Likewise, an alert claimed to arrive in under 60 seconds remains a marketing promise until independently measured. If the calendar stays stubbornly empty despite an active alert, see our no appointment slot available guide.
Actual coverage matters more than the headline number
"All departments" does not necessarily mean "all processes." A single prefecture may use different platforms for residence permits, naturalisation, and medical commissions. Always check the exact name of your process and its corresponding official calendar.
What Perfecture claims
Documented alert channels
Perfecture displays 750+ processes across 200 prefectures and continuous monitoring at a variable rate. Its homepage documents SMS and email alerts. Push notifications and Telegram are also claimed but remain to be confirmed because neither was corroborated on the homepage or in the terms on the review date. Booking always stays in your hands.
