Inspektor Gadget vs Robusta: at a glance
What is Inspektor Gadget?
Inspektor Gadget keeps cutting the privileges an eBPF tool has to ask for.
Inspektor Gadget v0.57.0 lets gadgets run rootless with cap_bpf, cap_perfmon and cap_sys_ptrace, and adds a flag that drops CAP_SYS_ADMIN on Kubernetes deployments. v0.56.0 introduced experimental multi-tenancy through TokenReview and RBAC. The v0.56.1 and v0.56.2 patches backported USDT parsing fixes, so crafted binaries cannot crash the process or exhaust memory, and bounded owner reference enrichment.
What is Robusta?
Robusta's recent releases patch its runner image rather than add features.
Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.

Inspektor Gadget
2.5INFRA · APIS
Inspektor Gadget keeps cutting the privileges an eBPF tool has to ask for.
◆ Current state
Inspektor Gadget v0.57.0 lets gadgets run rootless with cap_bpf, cap_perfmon and cap_sys_ptrace, and adds a flag that drops CAP_SYS_ADMIN on Kubernetes deployments. v0.56.0 introduced experimental multi-tenancy through TokenReview and RBAC. The v0.56.1 and v0.56.2 patches backported USDT parsing fixes, so crafted binaries cannot crash the process or exhaust memory, and bounded owner reference enrichment.
◆ Where it's heading
The direction is lower trust: fewer privileges for the tool and less trust in the binaries it inspects. Multi-tenancy, rootless runs and hardened ELF parsing all remove reasons a security team would refuse to deploy it. GPU telemetry from v0.55 has no follow-up in the recent notes.
◆ Prediction
Multi-tenancy graduating from experimental remains the likely next milestone as it pairs with reduced-privilege deployments. Whether GPU telemetry gets gadget consumers soon is unclear from these entries.
Robusta
5.0INFRA · APIS
Robusta's recent releases patch its runner image rather than add features.
◆ Current state
Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.
◆ Where it's heading
Since late August the project has been treating its container image as the product surface that needs attention, with CVE patching handled by backporting packages from the next Debian release. The feature line that added workflow chaining, JSON logs and new alert sources has gone quiet in these entries. The 0.53 tag does not appear in the feed, so part of the picture may be missing.
◆ Prediction
Expect more runner-image CVE releases on the alpha line. Whether feature work on Holmes integration or alert sources resumes is not visible in these entries.
