Built by Developers,
For Developers
Uptimes started as a personal frustration — why should you need Docker, a VPS, or a SaaS subscription just to know if your endpoint is responding? We built the answer right inside your browser.
Monitoring Shouldn't
Require Infrastructure
Traditional uptime monitoring forces you into a dependency loop — you need a server to monitor your server. That's backwards. With modern browser APIs, we can ping endpoints, measure latency, and track history without any backend at all.
Our mission is to eliminate every unnecessary barrier between a developer and the insight that their service is running. No billing, no onboarding wizard, no Docker Compose file. Just open your browser, paste a URL, and know.
Your URLs stay on your device. Zero telemetry. Zero data collection.
Fully open source. Inspect every line of code we ship.
Install once. Works instantly. No config files, no accounts.
Meet the Team
A small, passionate group of engineers and designers who believe great tools should be simple.
Alex Rivera
Full-stack dev turned tool-builder. Spent 5 years building cloud infrastructure before getting tired of it and building something that doesn't need any.
Sofia Kim
Product designer obsessed with removing friction. If it takes more than two clicks, she'll redesign it until it doesn't.
How We Got Here
The Idea
Alex gets paged at 3am for a down server. The monitoring tool that should have caught it first was also down. The idea for Uptimes is born.
First Prototype
A hacky Chrome extension with a hardcoded URL and a blinking green dot. Shared with 20 developer friends — 18 asked "when can I use it for real?"
Public Beta
Sofia joins and redesigns the entire UI. Jamal rewrites the ping engine for accuracy. We launch to 500 beta users and hit 1M pings in the first month.
10,000+ Users & Growing
Used by indie developers, agencies, and startups across 60+ countries. Still 100% free. Still requires zero infrastructure. Just as it should be.
What We Stand For
Simplicity Is a Feature
Every feature we don't ship is a potential source of confusion we eliminated. We'd rather do fewer things flawlessly than many things adequately.
Your Data Is Yours
We don't want your URLs, your usage patterns, or your email address. Everything Uptimes knows about your monitors stays in your browser.
Free Means Free
No freemium trap. No "upgrade for more monitors". The extension is and will remain free. We earn nothing from your monitoring activity.
Ship Fast, Break Nothing
We iterate quickly but never compromise the core reliability of the ping engine. Getting the number right matters more than shipping the next feature.
