Nautobot vs TestingBot: at a glance
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.
What is TestingBot?
TestingBot's autumn work is plumbing: a rebuilt tunnel and another bug-tracker link.
TestingBot runs a cross-browser and real-device cloud. October brought Tunnel v5, a rewrite of its local-testing tunnel with host allowlists, SSH host key checks, SOCKS5, Kerberos and PAC proxy support, self-contained builds without Java, and health endpoints with JSON logs. A Linear integration files bugs from manual sessions, and an iPhone Duo simulator lets teams test a foldable iPhone before Apple ships it. Vibium's agent-driven automation joined the grid in August and Mobilewright tests in October.

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.

TestingBot's autumn work is plumbing: a rebuilt tunnel and another bug-tracker link.
◆ Current state
TestingBot runs a cross-browser and real-device cloud. October brought Tunnel v5, a rewrite of its local-testing tunnel with host allowlists, SSH host key checks, SOCKS5, Kerberos and PAC proxy support, self-contained builds without Java, and health endpoints with JSON logs. A Linear integration files bugs from manual sessions, and an iPhone Duo simulator lets teams test a foldable iPhone before Apple ships it. Vibium's agent-driven automation joined the grid in August and Mobilewright tests in October.
◆ Where it's heading
The summer made the platform fit for teams; the autumn makes it fit for corporate networks and CI. Tunnel v5 targets the place enterprise trials usually stall, behind proxies and security reviews, and its config-file and environment-variable setup suits pipelines and Docker. The integration list keeps growing one tracker at a time, while the device catalogue continues its usual rotation.
◆ Prediction
Expect further CI-oriented tunnel and reporting work, and more automation frameworks on the grid alongside Mobilewright and Vibium. The Vibium MCP path has had no follow-up in these entries.
