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.

What is TestingBot?

TestingBot's autumn work is plumbing: a rebuilt tunnel and another bug-tracker link.

TestingBot runs a cross-browser and real-device cloud. October brought Tunnel v5, a rewrite of its local-testing tunnel with host allowlists, SSH host key checks, SOCKS5, Kerberos and PAC proxy support, self-contained builds without Java, and health endpoints with JSON logs. A Linear integration files bugs from manual sessions, and an iPhone Duo simulator lets teams test a foldable iPhone before Apple ships it. Vibium's agent-driven automation joined the grid in August and Mobilewright tests in October.

Jaeger vs TestingBot: editorial side-by-side

2.5

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.

5.0

TestingBot's autumn work is plumbing: a rebuilt tunnel and another bug-tracker link.

◆ Current state

TestingBot runs a cross-browser and real-device cloud. October brought Tunnel v5, a rewrite of its local-testing tunnel with host allowlists, SSH host key checks, SOCKS5, Kerberos and PAC proxy support, self-contained builds without Java, and health endpoints with JSON logs. A Linear integration files bugs from manual sessions, and an iPhone Duo simulator lets teams test a foldable iPhone before Apple ships it. Vibium's agent-driven automation joined the grid in August and Mobilewright tests in October.

◆ Where it's heading

The summer made the platform fit for teams; the autumn makes it fit for corporate networks and CI. Tunnel v5 targets the place enterprise trials usually stall, behind proxies and security reviews, and its config-file and environment-variable setup suits pipelines and Docker. The integration list keeps growing one tracker at a time, while the device catalogue continues its usual rotation.

◆ Prediction

Expect further CI-oriented tunnel and reporting work, and more automation frameworks on the grid alongside Mobilewright and Vibium. The Vibium MCP path has had no follow-up in these entries.
