Standard web performance tools guess based on software. We measure the physical reality of the silicon.
Powered by the SpeedPower™ Database, our deterministic profiling architecture captures your users' physical hardware limits in real-time. Zero computational overhead. Zero privacy compromises.

We don't rely on device recognition. Upon initialization, our ultra-lightweight (10KB) script capture the dynamic browser performance signature.
The signature are instantly cross-referenced against our SpeedPower Database. This is our proprietary, massive RUM (Real User Measurement) database, built from thousands of live execution benchmarks.
We deduce a clean, cacheable integer (like BDP 3 or AIR 4) directly to your frontend giving your code the exact intelligence it needs to adapt the execution of the application to the device.
Categorize incoming user traffic into four real-time performance categories, giving your frontend the exact hardware intelligence it needs to balance heavy payloads against local processing power.

Entry-Level. Legacy devices or low-power modes (e.g., iPhone 8 on battery saver, cheap Androids).
These devices will choke, overheat, or crash on heavy JavaScript or WebGL
Serve static HTML, disable animations, remove 3D elements
Basic. Older mid-tier devices, or mid-range phones on low-power mode or heavy load.
They can handle standard web applications but suffer from micro-stutters during heavy client-side routing.
Simplify DOM manipulations and pause heavy background polling to maintain a stutter-free 60fps experience.
Mid-Range. Modern average consumer hardware or high-end phones on low-power mode or heavy load.
Capable of handling standard SPAs and complex logic without noticeable delay.
Safe to execute rich interactive elements, standard WebGL elements, and local processing without degrading the UX
High-End. Flagship devices (e.g., iPhone 15 Pro, M3 MacBooks) with full power.
Massive CPU/GPU firepower.
Safe to unlock rich WebGL, 3D interactive elements, and complex real-time collaborative features.
The AIR index is specifically designed for Edge AI computing. It benchmarks the device's capability to run local AI workloads (using WebAssembly, WebGL, WebGPU, or WebNN) without degrading the core user experience or draining the battery.
Route all AI prompts to Cloud APIs (OpenAI, Anthropic).
Limited to sequential CPU computingCannot run LLMs locally without freezing the browser.
Suitable for very small, quantized tasks (like basic sentiment analysis).
Basic hardware acceleration kicks in, enabling light parallel computing.
Safe to execute medium-sized local models in the browser to save cloud costs.
Massive firepower capable of heavy matrix computation.
Execute full local LLMs and real-time computer vision entirely on the client.
The absolute pinnacle. Hardware featuring dedicated Neural Processing Units or high-end WebGPU support
Having hardware intelligence is only half the battle, your application needs to act on it instantaneously. Using our script you can use BDP or AIR scores to adapt the execution of your application.
Our Impulse Engine runtime orchestrator is designed not only to adapt application workflows but also to parallelize execution across all available device resources. It acts as an intelligent router for your application's component tree, hot-swapping frontend payloads, running worklods in parallel, doing a parallel React rendering in your browser to get the best UX and responsiveness of your application.
Automatically switches uncompressed WebGL layers or interactive models into lightweight, static alternatives on the fly based on the physical score.
Pauses heavy, non-critical background scripts, tracking pixels, and third-party polling cycles the exact microsecond a device shows signs of hardware distress.
Constantly monitors thread-level responsiveness during the user session, downgrading non-essential layout calculations if the hardware triggers a thermal throttling warning.
The SpeedPower™ Benchmark: We map raw execution capacity for JavaScript, WebAssembly (WASM), and AI/Visual tasks (WebGPU/OpenGL) in real-time. Test your own device's SpeedPower score!
By deploying a passive, ultra-lightweight (10KB) script, we capture deeply scientific, browser-level metrics without affecting your Core Web Vitals.
Protect your conversion rates by mapping your data precisely across 4 physical BDP tiers.
Deploying a third-party script shouldn't compromise your compliance. ScaleDynamics measures the mechanical limits of the silicon rendering your page—not the person behind the screen.
We capture absolutely no Personally Identifiable Information.
No IP addresses are logged, no cross-site behavior is tracked, and no cookies are required.
Built from the ground up to be strictly GDPR and CCPA compliant.
