Tarayıcı Desteği Testi

(Dokümantasyon İngilizcedir)

What it does

Audits your actual browser against 30 modern web capabilities - WebGPU, WebGL 2, WebAssembly (SIMD, threads), Service Workers, OPFS, WebAuthn, View Transitions, Popover API, and more - grouped into 8 categories: Graphics, Compute, Storage, Connectivity, Media, Sensors, Security, and Platform. Each check carries a weight (1-3), and the results roll up into a weighted readiness score 0-100 with a tier label, from Fully modern (90+) down to Legacy browser (below 35).

Detection is three-tier: passive API-presence checks run automatically on load; live tests (20 checks carry a demo chip) actually execute the feature - render a canvas gradient, draw a WebGPU triangle, validate a SIMD WASM module, write to IndexedDB/OPFS; and 8 triggerable actions (Camera, Microphone, Geolocation, Clipboard, Notifications, Vibrate, Fullscreen, Web Share) let you fire real permission-gated APIs yourself. Everything runs 100% client-side - nothing leaves your browser, and results are not stored.

How to use it

1. Open the tool - the scan starts automatically, revealing the 30 checks row by row (~55 ms each) with the browser label (parsed from your user agent) above the summary.
2. Read the gauge: the weighted readiness score, plus tallies of supported / limited / needs-HTTPS / unsupported checks.
3. Click any row to expand it: the one-line explainer, a per-browser detail note when present (e.g. vendor prefix, measured value), and a Copy-able JS detection snippet like !!document.createElement('canvas').getContext('webgl').
4. On a row with a demo chip, click ▶ Run live test to execute the capability for real. The outcome shows as works, failed, or n/a, with detail such as the GPU name or the rendered canvas size.
5. Use Show all snippets to expand every row at once, Re-run scan to re-detect from scratch, or Copy share link to copy the current URL with your results encoded in it.
6. Scroll to Trigger an action and click any of the 8 buttons - Device (Camera, Microphone), Permission (Geolocation, Clipboard, Notifications), Output (Vibrate, Fullscreen, Web Share). Your browser may prompt for permission; each button reports success, denied, not available, or error.

Examples

Weighted scoring (verified against the score module, src/tools/browser-support/score.ts) - status contributions are supported = 1.0, limited = 0.5, needs-HTTPS = 0.3, unsupported/unknown = 0, each multiplied by the check’s weight:

All 30 checks supported                        → score 100
All supported except WebGPU (weight 3)         → score 95
All supported except Canvas 2D (weight 2)      → score 96
WebGPU reported "limited" instead of supported → score 97
WebGPU reported "needs-https"                  → score 96
WebGPU unknown                                 → score 95

With only WebGPU unsupported, the category breakdown reads Graphics 70 (4/5 supported), and 100 for Compute, Storage, Connectivity, Media, Sensors, Security, Platform.

Shareable links (verified against src/tools/browser-support/share.ts) - after a scan, the report is packed (one character per check in catalog order: s supported, l limited, h needs-https, x unsupported, ? unknown), JSON-encoded, and base64url-encoded into the ?r= URL parameter. The 30-check report above packs to sssxssssssssssssssssssssssssss and encodes to a 116-character ?r= string; decoding it reproduces the exact statuses, score, and browser label. Opening a shared link replays the saved report instead of re-scanning your browser.

Good to know

• Private: detection, live tests, and actions all run in your browser. No results are uploaded; the share link only works because the data itself lives in the URL.
• “Needs HTTPS” means the API exists but is restricted to secure contexts - the tool flags it lower than “limited” because you cannot ship on it from your current context.
• The live tests and actions are the honest layer: API presence can lie (a vendor may ship a stub), but a rendered WebGPU triangle or a real IndexedDB write cannot.
• The readiness score is weighted toward foundational capabilities (WebAssembly, WebGPU, Service Workers weigh 3), so missing one modern nicety costs less than missing a baseline.
