PawMates Pro vs Animal Shelter Manager (ASM): A Side-by-Side Comparison
Animal Shelter Manager is genuinely free and open source — but with a self-hosted open-source install you also inherit the security burden. Patching, server hardening, spam filtering, and intrusion monitoring are all on you, and adopter PII is the data at risk. Here's a fully managed, secure, and supported alternative.
Isn't open source supposed to be more secure because anyone can audit the code?
In theory, yes. In practice for a self-hosted shelter install, security depends on the team running the server: how fast you patch CVEs, how you've hardened the OS, whether you have spam and bot filtering on public adopter forms, whether PII is encrypted at rest, whether logins are rate-limited, whether you have intrusion monitoring, and whether you have backups you've actually tested. Most shelters don't have IT staff dedicated to that work — which is why self-hosted shelter instances are routinely targeted by spam bots and credential-stuffing attacks. PawMates Pro centralizes all of that under a vendor whose full-time job is keeping it secure.
Why pay for PawMates Pro when ASM is free?
PawMates Pro Rescue Free is $0/month for foster-first rescues (up to 25 active pets). Kennel shelter plans start at $149/month (Starter) and scale to Growing ($299), Pro ($599), and Large ($899) by intake volume. Rescue Plus is $79/month. Every plan includes unlimited users, free data migration, daily backups, and a free adopter app — no per-seat or per-adoption platform fees. ASM's license is free; hosting, maintenance, security patching, upgrades, backups, and lost staff time aren't. PawMates Pro is a single bill that covers managed hosting, security, support, maintenance, and free migration — and adds compatibility-based adopter matching, Animal Control, and a fundraising engine ASM doesn't include.
Can you migrate from a self-hosted ASM install?
Yes. Our migration team handles self-hosted ASM extracts as well as community-hosted exports.
Will I lose features I rely on in ASM?
Almost certainly not — PawMates Pro covers the full ASM module set and adds capabilities ASM doesn't (compatibility-based adopter matching, Animal Control, fundraising, VetPetz medical bridge).
How long does it take to switch?
1–2 days for off-site setup, 1–2 hours on-site training. Most teams are productive day one.
