Building a bitwise calculator that didn't need to exist — but 3,000 devs a month use it

Hey PH! 👋

I built BitwiseCalc (https://bitwisecalc.com) because I kept switching between macOS Calculator and Python REPL every time I needed to do binary math.

The idea is dead simple: pick your operation (AND, OR, XOR, NOT, left/right shift), enter numbers in any base (binary, decimal, hex), and get the result in all four bases instantly — binary (32-bit), octal, decimal, hex. With step-by-step bit breakdowns.

What started as a weekend scratchpad now gets ~3,000 monthly visits from developers, CS students, and the occasional embedded engineer. No signup, no ads, all client-side JS.

Launching on Product Hunt in 2 days. Would love your feedback before then — what's missing, what's broken, what would make it your go-to bitwise tool?
