Jaeger vs Prowler
A side-by-side editorial comparison of Jaeger and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
Jaeger vs Prowler: 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 Prowler?
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.

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.
Prowler
7.5INFRA · APIS
Prowler 5.49 asks a new question after each scan: which of your servers run an image under attack?
◆ Current state
Prowler ships a minor release every one to two weeks. 5.48 added Realtime for AWS, which checks resources as CloudTrail events arrive and can alert, open a Terraform pull request or fix the resource. 5.49 adds emerging threat signatures: a vulnerability described as data, matched against the machine images of every compute instance on AWS, Azure and Google Cloud, with Amazon Inspector clearing hosts patched in place. Prowler Cloud supplies a threat catalog and turns each threat into an Exploitability issue per account.
◆ Where it's heading
Prowler is moving from configuration checks toward telling teams what is actually exploitable now: Realtime cut the wait for detection, and threat signatures cut the wait for a new check when a vulnerability lands. The free engine keeps the mechanism, while the maintained catalog and issue triage sit in Prowler Cloud.
◆ Prediction
Expect the threat catalog to grow and exploitability issues to reach more providers or link into Realtime alerts in the next releases.
