Know when a third-party API breaks before your customers do

Checklane helps SaaS teams discover third-party API failures before their customers do. Unlike traditional uptime monitoring, Checklane focuses on the external services your product depends on. Key features: • API availability monitoring • HTTP error detection • Incident management • Email alerts When a dependency starts failing, timing out or degrading Checklane automatically creates an incident and notifies your team. The result: • fewer customer-reported issues • faster incident detection







I finally reached my first 10 users in my SaaS.
After weeks of building, rewriting the landing page, posting on Reddit and X, and talking to other founders, people are finally starting to try Checklane.
It's still very early, and I'm nowhere near product-market fit, but seeing real people create accounts and explore something you've built from scratch is a great feeling.
Checklane was born from a simple frustration:
Most monitoring tools tell you when your server is down.
I'm trying to solve a different problem: when your server is perfectly healthy, but your product isn't.
Things like:
Failed webhooks
Expired API keys
Broken OAuth flows
Third-party API outages
Scheduled jobs that silently stop running
If you've ever had one of those "everything was green, but customers were already affected" incidents, I'd genuinely love to hear your story.
