What is Expo?
Expo shut down its own coding agent and kept the MCP server — it wants to be the substrate.
Two SDK releases landed in quick succession, 56 in May and 57 at the end of June, alongside steady EAS work: Maestro test insights with flake detection, automated iOS device registration in Workflows, and a general availability date for EAS Observe. On the AI side the direction reversed — the Expo MCP Server became available on the free plan in May, and in July the Expo Agent closed beta ended with the project wound down. Entry bodies in this feed are thin, so specifics beyond the headlines are limited.
What is Rootly?
Rootly's AI stops summarizing incidents and starts investigating them.
Rootly runs incident response — on-call, alerting, status pages, retrospectives — and its AI work has been arriving in a clear sequence rather than as one launch. In July the agent moved into the web app as a chat panel on every incident, retrospective templates gained AI blocks that draft from incident data, Slack, and call transcripts with prompts and sources visible, and the newest release lets the AI pull evidence from observability, code, infrastructure, feature flag, ticketing, and documentation tools. Alongside that, the operational surface kept filling in: Cortex catalog sync, Intune policy support on mobile, an on-call pay calculator, and a one-command setup that pages your phone to prove the configuration works.
Expo vs Rootly: editorial side-by-side
Expo
6.3INFRA · APIS
Expo shut down its own coding agent and kept the MCP server — it wants to be the substrate.
◆ Current state
Two SDK releases landed in quick succession, 56 in May and 57 at the end of June, alongside steady EAS work: Maestro test insights with flake detection, automated iOS device registration in Workflows, and a general availability date for EAS Observe. On the AI side the direction reversed — the Expo MCP Server became available on the free plan in May, and in July the Expo Agent closed beta ended with the project wound down. Entry bodies in this feed are thin, so specifics beyond the headlines are limited.
◆ Where it's heading
Expo is consolidating around the build, test, and observe pipeline it already owns and stepping back from competing on the agent itself. Making the MCP server free while retiring Expo Agent puts the company underneath whichever assistant a developer already uses, rather than asking them to adopt another one. EAS is where the commercial weight sits, and the recent releases all reduce the manual work between a commit and a working build on a device.
◆ Prediction
Expect EAS Observe's August general availability to anchor the next stretch, with AI effort staying on the MCP surface that connects outside assistants to Expo projects.
Rootly
6.3INFRA · APIS
Rootly's AI stops summarizing incidents and starts investigating them.
◆ Current state
Rootly runs incident response — on-call, alerting, status pages, retrospectives — and its AI work has been arriving in a clear sequence rather than as one launch. In July the agent moved into the web app as a chat panel on every incident, retrospective templates gained AI blocks that draft from incident data, Slack, and call transcripts with prompts and sources visible, and the newest release lets the AI pull evidence from observability, code, infrastructure, feature flag, ticketing, and documentation tools. Alongside that, the operational surface kept filling in: Cortex catalog sync, Intune policy support on mobile, an on-call pay calculator, and a one-command setup that pages your phone to prove the configuration works.
◆ Where it's heading
The AI features are being built with their working shown — every prompt and source visible in retrospectives, evidence gathering that is explicitly read-only with nothing stored. That is a deliberate answer to the reason engineers distrust AI during an incident: an unattributed claim at 3am is worse than no claim. The direction is toward an agent that reaches into the same systems a responder would check, while the surrounding releases reduce the setup and configuration cost that has historically made incident tooling a quarter-long adoption project.
◆ Prediction
Evidence gathering that is read-only today is the obvious foundation for suggested remediation tomorrow; expect the next step to be Rootly proposing actions from that evidence, with the same source-visible framing used to make it reviewable.
