Hi Product Hunt community! 👋 I built crc-calc.com because I frequently needed a clean, fast, and straightforward CRC calculator without heavy ads or confusing layouts. Key Features: • Supports popular CRC-8, CRC-16, and CRC-32 algorithms (including Modbus and standard polynomials) • Works seamlessly with Hex, ASCII, and Binary inputs • Lightweight, responsive, and developer-friendly UI I'd love to get your feedback or hear about any specific algorithms/features you'd like me to add. Thanks for checking it out!

honestly this is super handy for quick checksums, and the option to grab ready-made C code for the lookup tables actually saved me a bunch of time on a firmware project.
