Loading your performance dashboard...
Agencies and developers deserve better performance testing tools. For too long, the options have been limited to expensive enterprise platforms that overwhelm clients with complexity, or free tools that generate reports too technical for anyone outside the dev team to understand.
We saw this gap and knew there had to be a better way. Teams need tools that are powerful enough for deep technical analysis, yet simple enough to share with clients, stakeholders, and non-technical team members.
That's why we built SpeedSignal—a performance testing platform that doesn't make you choose between depth and clarity. Visual filmstrips that show exactly when content loads. Resource waterfalls that pinpoint bottlenecks. White-label reports that agencies can proudly share with clients.
We're building the tool we wish existed when we were running performance audits and trying to explain complex metrics to clients who just wanted to know: "Is my site fast?"
Performance testing shouldn't force you to choose between power and simplicity
Make website performance testing accessible to every agency, developer, and business—without sacrificing depth or breaking the bank.
A world where performance isn't an afterthought, where agencies can prove their value, and clients can actually understand their site's health.
Built from the ground up for agencies and their workflows
Filmstrips and screenshots turn metrics into stories. Clients see the problem, not just numbers. Make performance issues instantly understandable.
White-label reports, multi-client dashboards, and shareable links. Built for how agencies actually work, not how developers wish they worked.
Paste a URL, get results in 2 minutes. Opinionated defaults that just work. No configuration fatigue, no learning curve.
