Inspektor Gadget vs Nextflow: 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 Nextflow?
The workflow engine keeps shipping weekly, and more of each release is Seqera plumbing
Nextflow runs two tracks at once: stable 25.10.x and 26.04.x lines taking fixes and plugin bumps, and a monthly -edge series where features land first. Recent work splits between language and runtime correctness — typed process outputs, record types, config parser v2, job array handling — and a growing set of integration points with Seqera's commercial platform. GPU metrics now appear in the workflow-level execution summary.

The eBPF observability tool just started reaching for the GPU.
◆ 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.
Nextflow
5.0INFRA · APIS
The workflow engine keeps shipping weekly, and more of each release is Seqera plumbing
◆ Current state
Nextflow runs two tracks at once: stable 25.10.x and 26.04.x lines taking fixes and plugin bumps, and a monthly -edge series where features land first. Recent work splits between language and runtime correctness — typed process outputs, record types, config parser v2, job array handling — and a growing set of integration points with Seqera's commercial platform. GPU metrics now appear in the workflow-level execution summary.
◆ Where it's heading
The engine is being wired progressively tighter to Seqera Platform. nf-tower has been consolidated into nf-seqera, a seqera:// filesystem provides data-links, the Seqera executor gained a per-task prediction model and a shellEnabled option, and Intelligent Compute scheduler run identifiers now propagate upward. In parallel the type system introduced with record types and typed outputs is still generating a steady stream of edge-case fixes, which is what a language change of that size costs.
◆ Prediction
Expect the type-system fixes to keep arriving on the stable lines while the edge series continues adding Seqera executor capability, since that is where nearly all new configuration surface has appeared.
