Uptime + status pages
A status page and uptime alerts for your side project — in 5 minutes
Competitors charge $13–$34/mo for the basics, or nickel-and-dime you with seats and add-ons. Greenbar is one flat $9/mo for faster checks, Slack webhooks, and five status pages — with a free tier that's actually usable (5 monitors, public page included).
Checks that stay out of your way
HTTP(S) monitors with SSRF guards, keyword matching, and 90-day uptime bars on your public page.
Incidents without the pager-suite tax
Auto open/resolve from consecutive failures, email/Slack/webhook alerts, and manual updates on the same timeline.
Developer-first
Clean webhook payloads today; config-as-code and deploy markers on the roadmap.
Simple pricing
One paid plan. No seats. Cancel anytime from the Stripe customer portal.
