What is Expo?
Expo kills its AI agent, SDK 58 beta arrives as EAS observability stack hits GA
Expo is at a turning point: the EAS infrastructure layer — build, update, and now observe — is maturing into production-grade tooling, with EAS Observe reaching GA in August and SDK 58 entering beta this week. Simultaneously, Expo shut down its AI Agent experiment after months in closed beta, a signal that building an AI coding assistant directly on the platform didn't reach product-market fit. The MCP server and Claude desktop integration indicate where the AI bet now sits: in connectors, not agents.
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.
Expo vs Jaeger: editorial side-by-side
Expo

Expo kills its AI agent, SDK 58 beta arrives as EAS observability stack hits GA
◆ Current state
Expo is at a turning point: the EAS infrastructure layer — build, update, and now observe — is maturing into production-grade tooling, with EAS Observe reaching GA in August and SDK 58 entering beta this week. Simultaneously, Expo shut down its AI Agent experiment after months in closed beta, a signal that building an AI coding assistant directly on the platform didn't reach product-market fit. The MCP server and Claude desktop integration indicate where the AI bet now sits: in connectors, not agents.
◆ Where it's heading
Expo is consolidating around EAS as an observable infrastructure layer, not as an AI product builder. The MCP server and third-party integrations (PostHog, Claude) suggest the strategy is to serve as a data and build substrate that AI tools operate on top of. SDK 58 will push new device capabilities through the standard pipeline; EAS Observe data becoming a programmable surface for AI tools is the natural next extension of this approach.
◆ Prediction
The next move is a stable SDK 58 release and deeper AI-tool integrations via MCP — Expo is betting its AI story on being the substrate that coding assistants operate on, not on shipping its own. Expect more one-command observability integrations to follow PostHog.
Jaeger

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.
