Jaeger vs Casdoor
A side-by-side editorial comparison of Jaeger and Casdoor — release velocity, themes, recent moves, and the top alternatives to consider.
Jaeger vs Casdoor: at a glance
What is Jaeger?
Jaeger folds its MCP server into the query service and drops Elasticsearch 6
Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.
What is Casdoor?
Ten releases in 48 hours, nearly all of them tightening who can do what, for how long
Casdoor is shipping a one-feature-per-release train at extreme cadence — ten tagged versions across two days, each carrying a single commit. The subject matter is unusually concentrated: seven of the last ten entries touch authorization, session lifetime, or OAuth protocol conformance rather than the UI or the connector surface. What used to be an SSO front-end with a Casbin engine behind it is being reworked at the permission layer itself.

Jaeger folds its MCP server into the query service and drops Elasticsearch 6
◆ Current state
Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.
◆ Where it's heading
Jaeger is treating machine consumption of traces as a first-class query path rather than an add-on. Merging jaegermcp into jaegerquery means the MCP surface ships wherever query ships, and trace summaries give both the UI and any agent a cheap way to scan results before pulling full traces. On storage, the direction is fewer supported backends maintained better, with ClickHouse steadily gaining parity.
◆ Prediction
Expect the trace-summaries path to become the default for search across storage backends, and further ClickHouse feature work as the Elasticsearch surface is trimmed rather than extended.

5.0INFRA · APIS
Ten releases in 48 hours, nearly all of them tightening who can do what, for how long
◆ Current state
Casdoor is shipping a one-feature-per-release train at extreme cadence — ten tagged versions across two days, each carrying a single commit. The subject matter is unusually concentrated: seven of the last ten entries touch authorization, session lifetime, or OAuth protocol conformance rather than the UI or the connector surface. What used to be an SSO front-end with a Casbin engine behind it is being reworked at the permission layer itself.
◆ Where it's heading
The direction is from standing access toward time-bounded, audience-scoped access. Permissions now carry a configurable expiry that revokes them automatically, token retention is set per organization instead of globally, and the OAuth path preserves RFC 8707 resource indicators so tokens can be bound to a specific target rather than the whole deployment. Alongside that, the enforcement path is being made cheaper — a batch permission API exists specifically to stop rebuilding the Casbin enforcer per call — which is what you build when permission churn stops being an admin-scale event.
◆ Prediction
Expect the expiry work to grow into a policy surface rather than a single field — per-role or per-application default TTLs, and an audit view of what expired when. The batch API and the RFC 8707 handling point the same way, so a first-class machine or service-identity flow is the plausible next step, though nothing in these entries names it directly.
