Message from the Founder
"When I created Loadly, my vision was simple: build a tool that lets developers test APIs quickly, without the heavy setup or complexity of traditional load testing. Something lightweight, intuitive, and accessible, so teams can spend less time configuring and more time creating.
Developers everywhere struggle with knowing how their APIs will perform in the real world. That often means downtime, stress, and frustrated users. With Loadly, I wanted to give instant insights, clear analytics, and confidence to deploy without second-guessing.
I also believe learning and collaboration are essential. That’s why Loadly combines a simple CLI with a modern dashboard—making it easy to share results, track progress, and continuously improve API reliability. My hope is that it helps everyone—from hobbyists to seasoned engineers—solve real problems faster and with more confidence.
I’m always open to feedback and contributions. Together, we can shape Loadly into a tool that truly supports the developer community and helps teams focus on what matters most: building amazing software."
