kndl 2026.10.6

Highlights

• Measuring Archived Sessions' disk no longer floods a Runner with file reads. The size shown in the archive list used to open up to 32 reads at every level of a Session's directory tree, so deep trees multiplied into thousands at once. Now a Runner reads at most 32 paths at a time for the whole measurement.
• A Session already being measured isn't measured twice. Opening the archive list again while sizes were still loading used to ask the Runner a second time; now it waits on the ask already under way, which always ends within 30 seconds.
• An offline Runner's Archived Sessions show their size as unknown. Before, a cached size could still be shown after its Runner went offline.
• A Runner reporting a negative load average no longer breaks its Monitor. Before, one such sample was stored and the Runner's history then failed to load until that point aged out; now the sample is rejected.
• Screen readers announce an Archived Session's size, as "Disk used by : ".

Changes since v2026.10.5

kndl 2026.10.5

Highlights

• A Session runs on its Creator's setup token, and only its Creator drives it. Each Session now uses the Claude credential of the person who created it, and other people watching can no longer send it prompts.
• Runners report their disk, memory and load. A Runner's row opens a Monitor with tiles and charts, keeps a week of disk-free history, and warns when disk is low.
• Archived Sessions show their disk use, and anyone who sees one can purge it. The archive list shows how much Runner disk each Archived Session takes, and purging frees that space.

Changes since v2026.10.4

kndl 2026.10.4

Highlights

• Haiku 5.5, and Claude Code 2.1.296 in every Session. Sessions used to run Claude Code 2.1.289, where Haiku was Haiku 4.5 with no effort level. They now run 2.1.296: the model picker offers Haiku 5.5, which takes an effort level like the others. Runners download the new build the first time a Session starts.
• Installing on Linux finishes. Onboarding and kndl doctor --fix failed with sudo: a terminal is required to read the password, and builds failed with bun: command not found right after install.sh installed Bun. Now sudo and polkit can ask for a password and the builds find Bun. A Runner that is already in the kvm group is told to reboot instead of being offered the same fix again. install.sh uses mise for Bun when it finds it.

• runner, mod: Sessions run Claude Code 2.1.296, with Haiku 5.5, and a script for the model table (#330)

• cli, repo, docs: onboard on Linux can ask sudo for a password, builds find Bun, and install.sh uses mise (#331)

Changes since v2026.10.3

kndl 2026.10.3

Highlights

• A smaller model picker, with effort on a slider. The composer used to have one large menu with a line under every model and an Effort submenu. Now it has two small buttons: the model, in a menu of names, and the effort level, on a stepped slider. Arrow keys move the slider, and Enter, a click or closing the popover sets the level. Escape leaves it as it was. During a running Turn, "Switch the model?" now asks once, not once per step.
• The Hub's version in the sidebar. The sidebar now shows which version of kndl the Hub runs, with its Channel.

Changes since v2026.10.2

kndl 2026.10.2

Highlights

• Queued prompts no longer get stuck, or run again. A prompt queued for a Session that was waking up could stay in the queue forever and be sent again on every Hub or Runner restart. Now its Turn is reported even when it starts before the Session links to the Hub, and the mod never runs a prompt it was given once already.
• No more "This session transcript was lost". A claude run inside a Session (by a script, a hook or Claude itself) could take over the Session's link to the Hub. The Session then woke into that other conversation. Now only the conversation the Runner launched links.
• kndl update works the first time on macOS. It no longer fails with Bootstrap failed: 5: Input/output error when it loads the new Hub before launchd has finished unloading the old one.

cli

• cli: wait for launchd to unload a service before loading it again (#319) (#320)

Changes since v2026.10.1

kndl 2026.10.1

Highlights

The first Release of kndl, and its first as open source (MIT).

kndl runs Claude Code Sessions in Sandboxes on machines you own, and lets your team watch and drive them together from the browser.

• Try it on one machine, then remove it: curl -fsSL https://raw.githubusercontent.com/kddige/kndl/main/install.sh | sh, then kndl onboard. kndl uninstall --purge removes it all. See the Quickstart.
• Multiplayer Sessions: everyone with access to a Repo sees its Sessions live, queues prompts, steers the running Turn, answers Claude's questions and types into its terminal, subagents included.
• A Sandbox per Session: Claude Code and everything it runs live in a microVM on a Runner, built from the Repo's Environment. The Claude credential stays outside it.
• Your machines, your Claude: a self-hosted Hub, Runners on a Mac with Apple Silicon or on Linux with KVM, and each person's own Claude subscription or API key.
• Releases and Channels: new installs follow stable, the latest Release. kndl update --channel dev follows main instead. Runners follow their Hub.

kndl is early: expect settings to change between Releases. Report security issues privately; see SECURITY.md.
