Inspektor Gadget vs Routinator

Inspektor Gadget vs Routinator: at a glance
What is Inspektor Gadget?
The eBPF observability tool just started reaching for the GPU.
Inspektor Gadget ships a feature release roughly monthly with bugfix releases in between, and the recent line has been steady kernel-side expansion: new gadgets, more eBPF program types, better stack symbolization. v0.55.0 breaks that pattern by adding initial GPU telemetry — a userspace daemon called gpu-ebpf-bridge that publishes GPU data through pinned BPF maps so gadgets can consume it. The rest of the release is the usual widening of eBPF surface plus stability work for high-churn nodes.
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.

◆ Current state
Inspektor Gadget ships a feature release roughly monthly with bugfix releases in between, and the recent line has been steady kernel-side expansion: new gadgets, more eBPF program types, better stack symbolization. v0.55.0 breaks that pattern by adding initial GPU telemetry — a userspace daemon called gpu-ebpf-bridge that publishes GPU data through pinned BPF maps so gadgets can consume it. The rest of the release is the usual widening of eBPF surface plus stability work for high-churn nodes.
◆ Where it's heading
Two directions run in parallel. The kernel-side surface keeps growing — SockOps, SkSKB and SkMsg program types, map pinning, non-destructive map iteration, OTel and Python stack symbolization — which makes the tool a more general eBPF runtime rather than a fixed set of gadgets. Meanwhile the output side is becoming opinionated about ecosystems it serves: v0.54.0 taught advise_networkpolicy to emit Cilium NetworkPolicy resources alongside Kubernetes ones. GPU telemetry extends the first direction past the boundary eBPF normally stops at.
◆ Prediction
The GPU work is explicitly described as an initial design laying groundwork, so expect the next releases to build actual gadgets on top of the bridge rather than to expand it further; the pinned-map plumbing added in the same release is what those gadgets would consume.

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.
