Hey PH 👋
I kept needing a quick JSON formatter, unit converter, or hash generator and landing on sites buried in ads and forced signups, so I built UtilZilla: a growing set of free tools that run entirely in your browser. Nothing you type or upload ever touches a server.
45 tools live today across calculators, converters, text tools, dev tools, and a new AI Tools category, a token counter using the real GPT tokenizer, an LLM API cost calculator, a JSON Schema validator for function-calling output, and an llms.txt generator. More going up every week based on what people ask for.
Would love feedback on what's missing, what's a tool you searched for recently and couldn't find a decent free version of?
