Checklane
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
When I started building SaaS products, I realized something strange.
Most monitoring tools told me one thing:
> Your server is healthy.
But they couldn't tell me whether my product was actually working.
An OAuth callback could silently fail.
A third-party API could start returning errors.
A webhook could stop being delivered.
An API key could expire.
A scheduled job could stop running after a deployment.
The infrastructure was green.
Users were the ones discovering the problems.
That's why I built Checklane.
The goal isn't to replace infrastructure monitoring—it's to monitor the business-critical parts of your product that users actually depend on.
The current version includes:
• HTTP/API monitoring
• Incident timeline
• Email alerts
• Google & GitHub sign in
• Dashboard with check history
• Multiple integrations and scheduled checks
It's still an early version, and right now I'm looking for honest feedback much more than rapid growth.
If you've ever had an incident where "everything looked healthy" but customers were already affected, I'd love to hear your story. Those real-world cases are exactly what I'm building Checklane around.
Thanks for checking it out ❤️
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.
