Jaeger vs Resend
A side-by-side editorial comparison of Jaeger and Resend — release velocity, themes, recent moves, and the top alternatives to consider.

Jaeger vs Resend: at a glance
What is Jaeger?
Jaeger 2.23 lets people and agents query traces in SQL.
Jaeger 2.23 adds a SQL query surface that compiles to its RFC 0005 structured filters, and the MCP search_traces tool now accepts a SQL statement. Storage search capabilities are exposed over api_v3 HTTP and gRPC, and ClickHouse now routes structured filters into SQL WHERE clauses. The release also breaks things: unused ClickHouse feature gates are gone, schema creation needs an explicit table engine, and the Gemini reference sidecar is removed.
What is Resend?
Resend now auto-revokes its API keys found leaked in public Docker images and datasets.
Resend ships API surface almost weekly and lets platforms such as v0, Stripe Projects and Laravel Cloud provision it inside their own setup flows. Its MCP server became discoverable from a single URL on October 26. On November 4 it joined TruffleHog's revocation program, so live Resend keys found in Docker images, Hugging Face datasets and other public sources are revoked automatically.

Jaeger 2.23 lets people and agents query traces in SQL.
◆ Current state
Jaeger 2.23 adds a SQL query surface that compiles to its RFC 0005 structured filters, and the MCP search_traces tool now accepts a SQL statement. Storage search capabilities are exposed over api_v3 HTTP and gRPC, and ClickHouse now routes structured filters into SQL WHERE clauses. The release also breaks things: unused ClickHouse feature gates are gone, schema creation needs an explicit table engine, and the Gemini reference sidecar is removed.
◆ Where it's heading
Since merging MCP into the query service in July, Jaeger has been rebuilding search: trace summaries, then span search and pagination, now SQL. Each release makes the query layer more expressive and more usable by AI agents, while ClickHouse becomes the backend that gets the new capabilities first.
◆ Prediction
Expect the SQL surface and structured filters to move from new to beta or stable over the next releases, with more backends routing filters natively like ClickHouse does now.
Resend
5.0INFRA · APIS
Resend now auto-revokes its API keys found leaked in public Docker images and datasets.
◆ Current state
Resend ships API surface almost weekly and lets platforms such as v0, Stripe Projects and Laravel Cloud provision it inside their own setup flows. Its MCP server became discoverable from a single URL on October 26. On November 4 it joined TruffleHog's revocation program, so live Resend keys found in Docker images, Hugging Face datasets and other public sources are revoked automatically.
◆ Where it's heading
As more keys are created by platforms and agents rather than by hand, Resend is adding controls around them: usage limits readable by API, and now automatic revocation of leaked keys. The pattern is distribution first, then safeguards for the keys that distribution creates.
◆ Prediction
Expect more provisioning integrations and key or usage controls aimed at platforms; the entries do not indicate a pricing change.
