What’s new
Version 1.3.0 · Updated August 26, 2026
• Fixed freezes when opening minified JSON — a file on a single long line no longer stalls the editor. Large and minified files now open smoothly. • The editor tells you when a file is minified instead of calling it "too large", and offers one-tap Prettify to make it editable. • Reworked the rating prompt so feedback reaches us instead of getting lost. • Stability improvements.
