    - 100% C (C++ headers), as simple as memcpy

    - No other base64 library encode or decode faster

    - Scalar can be faster than other SSE or ARM Neon based base64 libraries

    - SSE faster than other SSE/AVX/AVX2! base64 library

    - Fastest AVX2 implementation TurboBase64 AVX2 decoding up to ~2x faster than other AVX2 libs.

    - TurboBase64 is 3-4 times faster than other libs for short strings

    - Fastest ARM Neon base64

    - (2023.04) avx512 - 2x faster than avx2, faster than any other implementation

    - Dynamic CPU detection and JIT scalar/sse/avx/avx2/avx512 switching

    - Base64 robust error checking, optimized for long+short strings

    - Portable library, 32/64 bits, SSE/AVX/AVX2/AVX512, ARM Neon, Power9 Altivec

    - OS:Linux amd64, arm64, Power9, MacOs+Apple M1, s390x. Windows: Mingw, visual c++

    - Big endian + Little endian

    - Ready and simple to use library, no armada of files, no hassles dependencies

    Neat library, upvoted.

    Question: does this business model work well? The GPL+commercial license on request?

    Iā€™m hoping the answer is yes, would be great with some nuance/details/exposition, thanks!
