PermitSnag vs Arvie
Arvie does something genuinely different from a typical scanner: its AgentBook feature tries to book the cancelled site for you and only charges a fee when it succeeds. It is built for campsites, not wilderness permit lotteries. Here is where each one fits.
As of July 16, 2026, Arvie runs live agents that automatically book cancelled campsites through its AgentBook feature, charging a flat $19 fee only on a successful booking, and claims a 65% win rate across 4,700+ parks. PermitSnag tracks 754 US wilderness permits with cancellation alerts, group pools, and Fast Lane booking links.

What one purchase covers
$19 is 1 to 2% of the trip it unlocks. The price is set against what you lose if the permit never opens, which is the trip.
- Unlimited date windows on that permit. Track one date or thirty, and change them any time before your trip dates pass.
- One purchase, one permit. Where one permit is sold as several rows, like Mount Whitney or the Enchantments, the purchase covers all of them.
- Checks about every minute. Coverage runs until your trip dates pass.
$19 for the permit you want, $5 for each one after · $9.99/mo for every permit you are hunting.
Choose PermitSnag if…
- You need a wilderness permit lottery: calendars, deadline reminders, group pools, and odds. Arvie doesn't track permit lotteries at all.
- You want a flat monthly subscription rather than a per-scan or per-booking fee structure.
- You want alerts across permits and campsites in one account.
Where Arvie fits
- Arvie's AgentBook tries to book the cancelled campsite for you and charges a flat $19 only when it succeeds, so you don't have to be at your phone when one opens.
- It searches and books across 4,700+ parks, aimed at car camping. A wilderness permit is a different system, and PermitSnag is the one plugged into it.

Common questions
What is the difference between PermitSnag and Arvie?
PermitSnag tracks wilderness permit lotteries (calendars, reminders, group pools, odds) plus campsites, and tells you about each opening with a Fast Lane booking shortcut. Arvie is campsite-only, and its AgentBook feature can auto-book a cancellation for you, charging a flat $19 fee only when it succeeds.
Does Arvie handle permit lotteries like Half Dome or Whitney?
No. Arvie is built for campsite reservations, not wilderness permit lotteries. For lottery permits, you need a tool like PermitSnag that tracks application windows and results.
Is Arvie's AgentBook worth it?
If you want a cancelled campsite auto-booked without watching your phone, the pay-on-success model (free to start, $19 only if it books) is a fair deal. It solves a different problem than PermitSnag, which alerts you and hands you a Fast Lane link to the page that sells it, so you book it yourself.
