Browser API, WebGL and WASM Capability Probes
Inspect WebGL texture limits, renderer and extensions, P3, API exposure, touch points and WebAssembly shared-memory prerequisites locally.
About this browser api, webgl and wasm capability probes
Inspect WebGL texture limits, renderer and extensions, P3, API exposure, touch points and WebAssembly shared-memory prerequisites locally Performs protocol inspection, IP calculation, and network analysis client-side without sending probes or exposing network topology.
Protocol mechanics & network logic
Run the probes to read this page’s browser environment. The extended snapshot adds MAX_TEXTURE_SIZE, touch points, battery API exposure and WASM thread prerequisites to the original WebGL/P3/API snapshot. Clear removes the displayed snapshot; the original detector remains below.
Worked network diagnostic scenario
Scenario: Inspect the current browser APIs in one page session.
Sample input:
Processing: Read navigator, window, canvas, media-query and optional StorageManager values. If crossOriginIsolated is false, WASM thread prerequisites are reported missing even when WebAssembly is available. The actual texture limit and touch count come from your browser, not fixed example values.
Illustrative output:
Addressing limits & protocol boundaries
Values depend on the current browser, privacy settings, origin and graphics configuration. A null texture limit means unavailable, not zero. WASM creates only one 64 KiB shared memory and checks isolation, Worker and Atomics; it does not execute worker threads. WebGPU and battery report API exposure only: no adapter, battery level, permission or hardware benchmark is requested. No audio context or audio limit test runs. API flags do not establish GPU acceleration, game performance or device capacity. The original StorageManager estimate can fail; additional probes remain visible.
Addressing calculations and subnet models in Browser API, WebGL and WASM Capability Probes follow IETF RFC definitions. Ensure subnet masks and CIDR prefixes match your network topology.
Offline network inspection boundary
Address parsing and CIDR calculations in Browser API, WebGL and WASM Capability Probes run entirely client-side without probing external IP networks or transmitting routing data.

Frequently asked questions
What does this browser capabilities detector return?+
It reads the current page environment and returns JSON fields for userAgent, language, platform, hardwareConcurrency, deviceMemory when exposed, secureContext, mediaDevices, WebRTC, clipboard, Worker, WebAssembly, WebGPU, WebGL/WebGL2, WebGL version, optional debug renderer, extensions, Display-P3 media query, and optional StorageManager estimate. Values belong to the browser that runs it.
What input and controls does the page use?+
There is no meaningful user data input for this detector. Run locally reads browser APIs in the current page; Load sample does not create a portable hardware profile. The result is a JSON snapshot, so a different browser, permission state, graphics setting, privacy setting, origin, browser version, or headless mode can change it.
What are the API and precision boundaries?+
The result mixes API-presence checks and attempted WebGL context creation. webGpu only checks whether navigator.gpu exists; it does not create a WebGPU device. The tool lists names returned by WebGL getSupportedExtensions but does not test each extension or application workload. WebGL, renderer, device memory and storage fields can be false, null or estimates; no permission or performance guarantee follows.
What result should a run produce?+
The result is a JSON snapshot of the current browser and origin. A supported API appears as true or a reported value; an unavailable API can appear as false or null. WebGL renderer and storage estimates depend on permissions, privacy settings, graphics support, and browser state. The current session must be checked directly.
