About this browser capabilities & webgl inspector
Browser Capabilities & WebGL Inspector — browser-based utility.
How this tool works
Implements client-side Browser Capabilities & WebGL Inspector operations. Inspects navigator object, WebAssembly SIMD, WebGL 2.0 context, Web Workers, and StorageManager quotas specifically designed for a web application developer checks client browser hardware capabilities and api support.
- URL & Header Semantic Parsing: Ingests raw URLs or Cache-Control header tokens, validating syntax against RFC 3986/9110 specifications.
- Cache-Hierarchy Evaluation: Models browser cache vs CDN shared cache behaviors (evaluating max-age vs s-maxage and revalidation flags).
- Port & Protocol Lookup: Matches numeric ports to standard IANA assignments (e.g. 443 for HTTPS, 22 for SSH, 53 for DNS, 3306 for MySQL).
- Diagnostic Reporting: Visualizes cache expiration timelines and highlights conflicting caching headers (such as no-store combined with max-age).
Worked example
Scenario: Inspect the current browser APIs in one page session.
Sample input:
Processing: Read navigator, window, canvas, media-query and optional StorageManager values.
Illustrative output:
Limits and verification
Flags contradictory caching directives (e.g. combining 'no-store' with any 'max-age' value). URL parser strictly enforces valid URI schemes and flags invalid percent-encoded characters.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

How to use it
- Enter, paste, or select your input data into the Browser Capabilities & WebGL Inspector workspace controls.
- Review available parameter fields, units, formats, or options configured for your task.
- Click the action button or observe immediate live calculations rendered in your browser runtime.
- Inspect the resulting output and any diagnostic messages, then copy or download the result if needed.
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?+
A Boolean means an API or context was exposed during this run; it does not prove a feature will work for every workload. WebGL fields can be false or null, debug renderer can be null, deviceMemory can be unavailable, and storage usage/quota are estimates. It does not benchmark speed, test camera or microphone permission, enumerate devices, inspect extensions, detect all APIs, or guarantee compatibility.
What did the isolated browser snapshot check establish?+
Before running the tool, the check read the same page APIs independently and compared every returned field. The result matched that headless Chrome session, including the exposed GPU and WebGL fields. Captured requests contained no submitted tool payload; this describes that session only, not an absence of other resources or network activity.
