Shibb Pseudolocalizer

The best, most comprehensive free PseudoLOC tool available.

Realistic multilingual pseudolocalization- Homoglyphs plus Thai, Cyrillic, CJK, and Vietnamese characters, not just accented Latin.

Expansion follows IBM's published localization data, so short strings grow the most, and longer strings taper down, rather than expanding by the same percentage everywhere.

Finds overflow in fixed-size boxes, Auto Layout frames, and containers that merely *look* bounded but aren't structurally clipping.

Recognizes and skips placeholders, dates, numbers, technical IDs, and already-pseudolocalized text- nothing gets double-processed or corrupted.

Deterministic output: re-running against an unchanged design gives the same result every time, not a different roll of the dice.

Optional RTL and vertical-script edge-case testing (Arabic, Hebrew, Thai, Vietnamese) for teams targeting those locales.

Summary report describes every issue found, with an exportable log- or just a one-line toast if you'd rather not open a panel at all.
