A side-by-side editorial comparison of k0s and Nautobot — release velocity, themes, recent moves, and the top alternatives to consider.
k0s vs Nautobot: at a glance
What is k0s?
k0s opens its 1.37 line while security fixes ride the older branches.
k0s published v1.37.1 alongside 1.36.5, 1.35.9 and 1.34.12 on the same morning, so four branches are now live. The older branches took Kubernetes patch bumps, etcd 3.6.15 and deferred manifest directory creation, and 1.36 also scoped the worker autopilot to its own Node. In September, 1.36.4+k0s.1 and 1.35.8+k0s.1 shipped a fix for GHSA-qjgc-wmg7-3jc3, with csr-approver hardening on the 1.35 branch.
What is Nautobot?
Nautobot's October releases are a permissions audit: objects users can't view kept leaking.
Nautobot's 3.2 and 2.4 lines have shipped same-day security releases every two weeks since September. v3.2.8 and v2.4.45 lead with stored XSS fixes and a long run of cases where jobs, imports and REST related-object handling accepted or revealed objects the user could not view, including other users' API tokens. v3.2.7 and v2.4.44 closed a Jinja2 sandbox escape and added timeouts for regular-expression evaluation. v3.2.6 moved SSO login to HTTP POST, breaking bookmarked SSO URLs.
k0s vs Nautobot: editorial side-by-side
k0s
5.0INFRA · APIS
k0s opens its 1.37 line while security fixes ride the older branches.
◆ Current state
k0s published v1.37.1 alongside 1.36.5, 1.35.9 and 1.34.12 on the same morning, so four branches are now live. The older branches took Kubernetes patch bumps, etcd 3.6.15 and deferred manifest directory creation, and 1.36 also scoped the worker autopilot to its own Node. In September, 1.36.4+k0s.1 and 1.35.8+k0s.1 shipped a fix for GHSA-qjgc-wmg7-3jc3, with csr-approver hardening on the 1.35 branch.
◆ Where it's heading
The branch-parallel pattern is holding and now has a new top line. Lifecycle safety stays the core work: reset steps wired to contexts, autopilot retries and discovery refreshes, and autopilot scope limited to its own node. The 1.37 notes read as a long development log rather than a curated release, which fits a project that lets upstream Kubernetes carry the feature story.
◆ Prediction
Expect the next Kubernetes patch round to reach all four branches within hours of each other, and the oldest of them to drop off now that 1.37 is out, though these notes do not state a support window.
Nautobot
5.0INFRA · APIS
Nautobot's October releases are a permissions audit: objects users can't view kept leaking.
◆ Current state
Nautobot's 3.2 and 2.4 lines have shipped same-day security releases every two weeks since September. v3.2.8 and v2.4.45 lead with stored XSS fixes and a long run of cases where jobs, imports and REST related-object handling accepted or revealed objects the user could not view, including other users' API tokens. v3.2.7 and v2.4.44 closed a Jinja2 sandbox escape and added timeouts for regular-expression evaluation. v3.2.6 moved SSO login to HTTP POST, breaking bookmarked SSO URLs.
◆ Where it's heading
Permissions were already the sustained theme in August, and the work has moved from Saved Views to the general paths every App relies on. New helpers such as restrict_queryset() and mock_wsgi_request() in the apps API, plus the fixes in WritableNestedSerializer, hand the same checks to App developers. The number of advisories per release points to a systematic review rather than a single report.
◆ Prediction
Expect App authors to be pointed at those helpers, and further advisories in the same object-visibility class in the next paired releases. v3.2.8's warning that Pillow 13 cannot run on Python 3.10 makes that version's support the likely next removal.
