Kaleidoscope 6.7 added Commit History to the changeset sidebar. Kaleidoscope 7 adds a visual commit graph, making branches, merges, and relationships between commits easier to understand.

Kaleidoscope 7 introduces Live Working Copy Changes.
Files that become modified, new files that appear, staging changes, commits, and reverts can now all be reflected in an open changeset. No more closing and reopening the comparison to see what changed.

Kaleidoscope 7 is here. Working Copy Changes now update in real time as files change—whether those changes come from you, a terminal command, or a coding agent. Open a changeset once. Leave it open. Kaleidoscope keeps following along.

In case you missed it: Kaleidoscope 6.8 Beta includes our first batch of compatibility fixes for macOS Golden Gate Beta (27.0). If you’re already running the Golden Gate beta, now would be a great time to see how Kaleidoscope behaves—and let us know what we missed.

Kaleidoscope 6.8 Beta 2 is out. The focus of this beta is macOS Golden Gate compatibility. If you’re running the Golden Gate beta, please give it a try and tell us what breaks.

Working with AI-generated changes usually means working in parallel—across branches, worktrees, and multiple iterations. Kaleidoscope 6.7 adds better support for that: • compare across worktrees • outline view for changesets • commit history in the sidebar

Fancy a small Easter egg hunt this weekend? 🐰 There’s a new Kaleidoscope public beta to explore: changesets in a folder-based hierarchy, commit history right in your changesets, Git worktree support, and improved image alignment. Let us know what you discover.

Comparing screenshots that don’t quite line up? Kaleidoscope 6.6 now aligns them automatically using AI. Works with UI tests, web pages, and real-world app screenshots. Manual adjustment is still there when you need it.

Also new in Kaleidoscope 6.5: you can now choose to open SVG files as images instead of comparing the source XML. Particularly useful for tracking small changes to SF Symbols assets.

Kaleidoscope 6.5 takes Image Comparison further: Zoom out to see differences. Zoom in to understand them. Pixel Comparison lets you inspect image changes pixel by pixel — down to exact color values.

What exactly changed in those pixels? Kaleidoscope 6.5 introduces Pixel Comparison — a new way to inspect and compare individual pixels down to the smallest color differences. We wrote a deep dive on how it works and why it matters: blog.kaleidoscope.app/2026/01/27/t...

Kaleidoscope 6.5 is out! 🟦 Pixel Comparison lets you inspect and compare the exact values of individual pixels — from color swatches and hex values to native formats and perceptual color spaces. Sometimes “looks the same” just isn’t enough.

We just released Kaleidoscope 6.4.1 through Software Update – likely our final release of 2025. This update brings quality-of-life improvements to the brand new Image Comparison and handy new Text Filters.

 As always, let us know if you spot any issues or get inspired with new ideas!

Kaleidoscope 6.4 is out 🖼️

 Image Comparison has been completely rewritten — it’s faster, smoother, and can handle larger images than before.
 
If comparing images is part of your daily workflow, this release makes a real difference.

💬 Customer love for Kaleidoscope 6.1:
“This is a game-changer! Being able to edit either side of a diff directly in my preferred editor and having Kaleidoscope automatically refresh is such a smooth experience.”
