Frequently Asked Questions
Why is Slack included in the free plan?
We believe alerts should reach you where you work. Slack is where builders live, so we include it from day one.
Is there a free plan?
Yes! The Indie plan is free forever with 15 APIs and 30 days of history. No credit card required. You can upgrade to paid plans anytime for more features.
What's the difference between Public Catalog APIs and Custom APIs?
Public Catalog APIs are the 1,000+ services we already track (Stripe, AWS, Vercel, etc.). Custom APIs let you add and monitor your own endpoints or services not in our catalog. Custom monitors support four check types: HTTP (response time, status code), Ping/ICMP (host reachability), Port/TCP (open port checks) and Keyword (verify text appears or is absent in a response body).
What does "Unlimited APIs" mean in the Scale plan?
You can monitor any number of APIs from our public catalog. There's no cap. Track your entire stack without worrying about limits.
What is Stack Pulse?
Stack Pulse connects directly to your infrastructure providers via their APIs — Railway, Vercel, Neon, Stripe, Resend and 20+ more — to surface real operational metrics like active deployments, database health, email delivery rates and payment transaction status. Unlike public API monitoring (which checks if an endpoint responds), Stack Pulse shows you what's actually happening inside your account.
What are Products?
Products let you group monitors by project. For example, your SaaS product might depend on Stripe, AWS S3 and your own API — group them all under one Product to see a unified health score, get targeted alerts and create a dedicated status page.
How do monitor limits work with Products?
Monitor limits (Custom APIs, Website Monitors, Heartbeat Monitors) are per account, not per Product. For example, on the Startup plan you get 50 Website Monitors total — you can distribute them across your 3 Products however you like.
Can I switch plans anytime?
Yes! You can upgrade or downgrade your plan at any time. Changes take effect immediately and we'll prorate your billing accordingly.
Do you offer annual billing?
Yes! Save 20% with annual billing. Use the toggle above to see annual prices. Enterprise customers can also get custom billing terms.
What payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express) through Stripe. Enterprise customers can pay via invoice.
