Developer Tools

JSON, wallet mocks, timestamps, Base64 and random data generators for builders.

Encode text to Base64 or decode Base64 back to text — instant, client-side, nothing leaves your browser.

Convert a Unix timestamp to a human-readable UTC date and time, with seconds or milliseconds auto-detected.

Generate realistic-looking but fake wallet addresses for testing UIs and demos. For development only — never holds real funds.

Generate a random but realistic crypto portfolio — see the allocation as a table, and copy it as JSON for testing dashboards and mock APIs.

Generate UUIDs, random hex strings, numbers or passwords for testing and development — as many as you need at once.

Generate an array of realistic fake user records as JSON — ideal seed data for APIs, tables and frontend prototypes.

Convert numbers between hexadecimal, decimal and binary — handy for smart contracts, addresses and low-level data.
