PupVax is a free online tool — 2026 dog vaccine tracker. Track vaccinations, get reminders, breed-specific health needs. Free for all dog owners.
PupVax was built by an independent developer using AI-assisted coding tools. The entire site was built with Claude Code and Next.js, deployed on Cloudflare Pages. No venture funding, no big team. Just one person with AI as a force multiplier, shipping useful tools to the world.
PupVax is supported by advertising (Google AdSense). You get full access to all tools without paying anything, and we earn a small amount when ads are viewed. No paywalls, no premium tiers. If ads are annoying, use an ad blocker — the tools still work perfectly.
