Skipper vs Routinator
A side-by-side editorial comparison of Skipper and Routinator — release velocity, themes, recent moves, and the top alternatives to consider.
Skipper vs Routinator: at a glance
What is Skipper?
One pull request per version tag, and most of them are dependency bumps.
Skipper cuts a release for essentially every merged pull request — six tags between 27 July and 7 August, each containing a single change. Two of the six are Dependabot bumps to CI actions and a fuzzing base image, two are test-only adjustments, and one fixes an error type assertion. Every entry carries the same boilerplate pointing at the multiarch image in GitHub's registry.
What is Routinator?
An RPKI validator that now treats its own attack surface as the product
Routinator is a mature RPKI relying-party validator shipping on a slow, deliberate cadence — a handful of releases a year, each one gated behind release candidates. The current 0.15.x line is dominated by hardening: 0.15.2 resolves four CVEs surfaced by an external X41 D-Sec audit funded by the Sovereign Tech Agency. Feature work has narrowed to operational ergonomics — RRDP timeout tuning, repository-issue log separation, and making server mode degrade gracefully instead of stalling.

One pull request per version tag, and most of them are dependency bumps.
◆ Current state
Skipper cuts a release for essentially every merged pull request — six tags between 27 July and 7 August, each containing a single change. Two of the six are Dependabot bumps to CI actions and a fuzzing base image, two are test-only adjustments, and one fixes an error type assertion. Every entry carries the same boilerplate pointing at the multiarch image in GitHub's registry.
◆ Where it's heading
The visible work is maintenance of an already-stable proxy rather than feature development. What the test changes hint at is where the correctness concerns sit: an OPA policy test updated to explicitly deny truncated request bodies, because oversized JSON cannot be fully parsed and a policy that ignores input.truncated_body can be bypassed. That is authorization-under-load hardening, and it is the most interesting thing in the window even though it landed as a test.
◆ Prediction
The per-PR tagging rhythm will continue producing several versions a week regardless of change size. Readers tracking this product should expect the meaningful changes to be a small minority of the tags.

An RPKI validator that now treats its own attack surface as the product
◆ Current state
Routinator is a mature RPKI relying-party validator shipping on a slow, deliberate cadence — a handful of releases a year, each one gated behind release candidates. The current 0.15.x line is dominated by hardening: 0.15.2 resolves four CVEs surfaced by an external X41 D-Sec audit funded by the Sovereign Tech Agency. Feature work has narrowed to operational ergonomics — RRDP timeout tuning, repository-issue log separation, and making server mode degrade gracefully instead of stalling.
◆ Where it's heading
The arc is from feature-building to operator-trust engineering. Each recent release removes a way the validator can silently stop updating or be pushed into a panic: broken local exception files now warn instead of halting, transient connection errors no longer exit, and rsync argument handling is being locked down. Third-party audits are now part of the release process rather than an event.
◆ Prediction
Expect the 0.15.x line to continue with small hardening patches rather than new capability, with any remaining audit findings landing as point releases.
