If you’ve searched for a way to catch campsite cancellations, you’ve probably run into three names: Camping Alert, Campnab, and Campflare. All three watch Recreation.gov for openings and notify you. The differences are in price, scan reliability, and how flexible your search can be — and they matter more than they might seem at first glance.
The short version
- Campflare is completely free, with no paid tier at all. Scan speed varies by how popular the campground is, with no guaranteed interval. A solid choice if price is your only constraint.
- Campnab is paid-only ($10–$30/mo or $10–$20 pay-per-use), with scan speed tied directly to how much you pay — their fastest tier beats a flat 5-minute rate, but at a real cost premium.
- Camping Alert has both a real free tier and paid plans, with a guaranteed scan interval on every plan, plus natural-language flexible dates, area search, and cancellation probability scoring that neither competitor offers.
If price is your only concern
Campflare’s free, best-effort model is genuinely useful, especially for popular campgrounds it checks as often as every 45 seconds. We wrote a full honest comparison against Campflare, including where it beats us (free, iOS app, wilderness permit alerts) and where a paid guarantee still matters.
If you want the fastest possible scan at any price
Campnab’s top tier scans faster than our flat rate, full stop. What it costs you is nearly 4× the price of our Explorer plan, plus the absence of natural-language dates, area search, and probability data. See the full breakdown in our comparison against Campnab.
If you want flexible dates instead of one fixed shot
This is where Camping Alert differs most from both competitors. Neither publishes support for natural-language date ranges the way we do — “any weekend in July” as a single alert, rather than one exact date. We cover exactly why that matters in our piece on flexible dates.
If you want to know your odds before you even set an alert
Camping Alert’s cancellation probability scoring — based on historical drop rates, current booking percentage, and seasonal patterns — is unique among the three tools. Neither Campnab nor Campflare publishes anything comparable.
Stop refreshing. Start getting notified.
Camping Alert scans Recreation.gov every 5 minutes on paid plans (60 on the free tier) and texts or emails you the moment a site opens up.
Can you use more than one?
Yes, and plenty of people do — there’s no rule against running a free Campflare alert alongside a Camping Alert account for the sites where flexible dates or probability data matter most. See both full comparisons for the details: vs. Campnab and vs. Campflare.
