Greenbar

Greenbar is uptime monitoring for freelancers and small web agencies that look after many client websites. It is built around one idea: every client should have their own status page.

How it works: add a client, paste their URLs and Greenbar checks them over HTTP(S). You set the expected status codes and can add a keyword check ("contains" or "does not contain") to catch error pages that still return 200. Paid plans include 1-minute checks and Free includes 5-minute checks. Alerts go by email on every plan, and by Slack and signed webhooks on paid plans. You can also post manual incidents with a timeline of updates.

Status pages: each client gets their own public page showing each service's current state, 90-day uptime bars and incident history. You choose which monitors appear on each page, and monitor URLs are never shown. Pages have light and dark mode and a mobile-friendly layout. On paid plans a page can carry the client's logo and brand colour, and the "Powered by Greenbar" footer can be hidden.

Who it is for: freelancers and small agencies who build and look after websites for clients and want one place to watch every site, plus a page they can send to each client.

Pricing is per agency, not per client (USD): Free for 1 client page and 5 monitors; Freelancer $15/mo or $150/yr for 10 client pages and 50 monitors; Agency $35/mo or $350/yr for 30 client pages, 150 monitors and up to 3 logins. New accounts start with $100 in free credit, no card needed.

What problem it solves

Freelancers and small agencies look after many client sites and need one place to watch them all, plus a status page each client can check without asking.
