All tools run locally in your browser. Your data never leaves your machine.
Why YZIF?
YZIF is a suite of free online developer tools that run entirely in your browser: convert JSON into Go structs, TypeScript interfaces, Rust structs or Java POJOs; refactor nested if-else statements into guard clauses; visualize logic as flowcharts; build structured AI prompts; and test regex patterns or cron expressions.
Because every conversion happens client-side, your data never leaves your machine - safe for proprietary code, internal configurations and anything under NDA. No signup, no rate limits, no telemetry on your input.
Typical use cases
Backend developers scaffolding models from API payloads; DevOps engineers validating cron schedules before deployment; AI engineers standardizing prompt templates across a team; anyone reviewing legacy conditionals that have grown too nested to reason about.
