It's designed for cases like: - custom discount/voucher codes - giveaway or lottery tickets - product serial numbers printed on packaging - one-time passwords or secure tokens - bulk fake/test data - random strings

You control: - quantity (up to 250k per batch) - length (up to 40 chars + optional prefix/suffix) - exact character sets (letters, digits, symbols, Unicode/emojis) - precise position rules (e.g. letters in positions 1-3, digits after) - uniqueness (required or optional duplicates)

Three modes: basic (quick defaults), advanced (character sets + prefix/suffix), expert (per-position rules).

Export formats: CSV, XLS/XLSX, JSON, plain text.

Codes are generated on-the-fly and never stored on the server - files are deleted immediately after download. Configurations can be saved as shareable links.

No signup, no tracking, completely free.

(Note: this generates your own codes for use in your systems/promotions - it does not find or create codes for existing stores/services.)

The tool is a part of our upcoming code generation and management platform, which is currently in beta.

Feedback welcome. Thomas
