Inspektor Gadget vs Jaeger
A side-by-side editorial comparison of Inspektor Gadget and Jaeger — release velocity, themes, recent moves, and the top alternatives to consider.
Inspektor Gadget vs Jaeger: 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 Jaeger?
Jaeger's query service learns to search individual spans, not just whole traces.
Jaeger 2.21 and 2.22 extend the 2.x storage and query rework. ClickHouse storage moved to a stable feature gate in 2.21, and the release removed v1 HTTP endpoints the UI no longer calls. In 2.22 the query service gains FindSpans with RFC 0014 pagination, Elasticsearch span search, and structured filters promoted to beta, while native Elasticsearch trace summaries go stable.

Inspektor Gadget

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.
Jaeger
2.5INFRA · APIS
Jaeger's query service learns to search individual spans, not just whole traces.
◆ Current state
Jaeger 2.21 and 2.22 extend the 2.x storage and query rework. ClickHouse storage moved to a stable feature gate in 2.21, and the release removed v1 HTTP endpoints the UI no longer calls. In 2.22 the query service gains FindSpans with RFC 0014 pagination, Elasticsearch span search, and structured filters promoted to beta, while native Elasticsearch trace summaries go stable.
◆ Where it's heading
The earlier trace-summaries work made search cheaper; span search changes what can be asked. Pagination and structured filters give both the UI and MCP clients a way to query without pulling whole traces. MCP keeps getting practical limits and input checks, and search_traces no longer needs a service name on backends that declare support for that.
◆ Prediction
Expect span search to spread beyond Elasticsearch and memory storage, and structured filters to move from beta to stable as other gates have. Further removal of v1 surface is likely, since 2.21 already started it.
