The translation manager that does enough and nothing more.
Most translation platforms charge thousands per month for features you'll never touch. Keystring starts free and does what matters.
Three features.
Zero filler.
JSON import & export
Drop in your JSON files, edit visually, export back. No conversions, no lock-in — your files stay standard.
All languages, one view
Every key, every language variant, one screen. No tab-switching, no context loss. Spot missing translations instantly.
Intuitive editor
Search, filter, sort, edit. An interface designed to disappear. Spend time translating, not learning the tool.
