Masquerade: A Quiet Toolbox

Masquerade is a quiet toolbox for builders. Convert timestamps between epoch and ISO. Reformat JSON, YAML, and TOML. Decode base64 and JWTs. Read cron schedules in plain English. Move between hex, binary, decimal, and bytes. Translate colors across HEX, RGB, HSL, and OKLCH with WCAG contrast. Convert basis points to percent and back. Scan or generate QR. Then the deeper drawer: generate and inspect UUIDs and ULIDs. Hash with MD5 through SHA-512. Diff two texts. Subnet IPv4/IPv6 and CIDR blocks. Percent-encode URLs and edit query strings. Evaluate math expressions. Split and join lists. Generate passwords and tokens. Everything runs on-device. Nothing is collected, tracked, or sent anywhere. No accounts. No ads. No telemetry. Built with Cupertino. Typeset in IBM Plex.
