Loupe 0.1.5

Released 21 August 2026 — on GitHub

The first release since 0.1.2, and a large one: everything below either had no public build at all or is new since.

Added

Section titled “Added”
  • Tabs, and a history behind each one. The main area used to render exactly one view, so opening a pod lost the list it came from and following a related object was a one-way trip. Tabs open with ⌘T, close with ⌘W, and ⌘-clicking a row opens it in one of its own; ⌘[ and ⌘] walk a real back/forward history per tab.
  • A status bar. Cluster, guard, server version and any pending update, on one line that does not move. The cluster and its write guard used to live in the foot of the nav rail, which is no help once you are three panes deep in a manifest.
  • Sortable columns, in the units the columns are actually in. Ages sort as durations, ready counts as fractions, restarts as numbers — so 10m no longer sorts before 2d, and pod-2 comes before pod-10. Sorting a partly loaded listing says so.
  • Auto-update. Loupe checks once on launch and offers a new version in the status bar, verified against a signing key compiled into the binary. Also in the command palette as Check for updates.
  • Interface zoom — ⌘+, ⌘− and ⌘0, from the View menu, the keyboard or the palette, remembered across launches.
  • Several clusters stay connected. Switching back to one re-authenticates nothing and re-walks no API discovery.
  • Exec into a container, through a real terminal emulator rather than a text box that sends lines.
  • Port-forward manager, with forwards visible while they run instead of a terminal you have to leave open.
  • Operator actions — scale, rollout restart, delete, cordon and drain — behind confirmations, and hidden entirely where RBAC says no.
  • Merged log view. Tail every pod of a workload in one stream, colour-coded per pod, instead of opening them one at a time.
  • Log filtering, highlighting, and copy or save of what is on screen.
  • Related-object navigation — owners, selectors and references, so a pod is no longer an island.
  • Protected and read-only contexts, marked per context, with a diff shown before every apply.
  • Command palette (⌘K) and keyboard-first navigation.

Two tabs open, with the trail showing where a pod sits

Changed

Section titled “Changed”
  • A mark of Loupe’s own. The app wore the Krypton mark, byte for byte the same file as the runtime’s operator UI. The new one is a lens iris whose opening keeps the family’s hexagon — and, unlike its predecessor’s 1px lattice, survives being 16 pixels wide.
  • Breadcrumbs describe where an object sits, not how you got there. They used to be the tab’s visited history, which produced trails like Nodes › Pods › some-pod › Jobs › DaemonSets — six steps, none containing the next, in the one element whose meaning is containment.
  • Content sits in front of the chrome. The surface ramp was defined and never painted, so a table fell through to the window background while every bar of chrome around it was brighter. Light and dark now both run base → glass → content.
  • Listings are paged and watched. A page is fetched at a time, so time to first row follows the page size rather than the size of the cluster, and freshness comes from a watch rather than a ten-second timer.
  • The context picker stays instant on a kubeconfig with thousands of contexts: search text is built once rather than per keystroke, only visible rows are in the DOM, and recents and pins sit above everything.
  • The log viewer keeps up with chatty pods — lines batched on the Rust side, coalesced onto animation frames, and only the visible ones in the DOM.

Fixed

Section titled “Fixed”
  • A listing’s namespace filter, search and sort survive opening a row and coming back. They used to live in the page, which unmounts.
  • The terminal no longer rebuilds itself on every render, mangles its own output, or ships without the stylesheet that makes it a terminal.
  • Switching cluster no longer leaves tabs pointing at objects that do not exist in the new one.

Notes

Section titled “Notes”
  • Anyone on 0.1.2 must update by brew upgrade or a fresh download — there was no updater to offer them this one. From 0.1.5 onward Loupe can update itself.
  • Homebrew is told the app self-updates, so brew upgrade no longer reinstalls an older build over a newer one.

Getting it

Section titled “Getting it”
Terminal window
brew upgrade --cask loupe

The cask is marked auto_updates true, so pass --greedy if Homebrew declines. Other platforms: download from the release.
