Explore Mandelbrot, Julia, Burning Ship, Tricorn, Multibrot, and Newton fractals in real time, with deep zoom to roughly 10^290x. GPU-accelerated WebGL2 rendering hands off automatically to an arbitrary-precision CPU engine — integer fixed-point coordinates plus perturbation against a high-precision reference orbit, with rebasing for glitch-free images — so zooming keeps resolving real detail long after floating-point math runs out of digits. Pan, zoom (mouse, wheel, or pinch) with zoom-to-cursor, tune iteration depth (or let it track your depth automatically), escape radius, and power/exponent, drag an interactive Julia constant, copy full-precision coordinates, and choose from five color palettes with optional animated color cycling — 100% client-side.

Generate, verify, and inspect cryptographic hashes (MD5, SHA-256, SHA-512, SHA-3, Keccak-256, BLAKE2, BLAKE3, RIPEMD-160) and checksums (CRC32, Adler32, FNV-1a, Murmur3) 100% client-side with HMAC, chunked file hashing, and code snippets.
