Dev Tools

Developer utilities for UUID generation, timestamp conversion, regex testing, hashing, QR code generation, WebGPU benchmarking, WebNN NPU checks, and local ONNX model experiments.

What this category helps with

  • Generate identifiers, timestamps, hashes, and QR assets during development.
  • Debug regular expressions against sample text with live feedback.
  • Measure browser-visible GPU/NPU capability before choosing a local AI or WebGPU path.

Data handling notes

  • Crypto-grade UUID generation uses browser crypto APIs.
  • Hardware tests are browser-level measurements, not vendor lab benchmarks.

Tools in this category

  • UUID Generator

    Batch generate UUID v4 with one-click copy

  • Timestamp Converter

    Convert between timestamps and date/time formats

  • Regex Tester

    Test and debug regular expressions in real time

  • Hash Generator

    Compute MD5, SHA1, SHA256 hash values

  • GPU Stress Test

    FurMark-like browser stress test powered by Three.js WebGPU with real-time stability metrics

  • GPU Benchmark

    Run a fixed WebGPU scene for 60 seconds and sum per-second FPS as the final score

  • WebNN NPU Compute Measurement

    Estimate effective NPU compute available to the browser by running a WebNN NPU-only matrix multiplication workload

  • Local AI Model Runner

    Upload an ONNX model or enter a model download URL, then run browser-local inference with WebNN NPU/GPU first

  • QR Code Generator

    Generate custom QR codes with advanced features like colors, logo, and batch generation
