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.
What is Windmill?
A workflow engine where the AI builds the scripts and the enterprise gates come down
Windmill's July stream is dominated by AI sessions, now in beta and on by default: each session ties a chat to a workspace or fork with a live preview, builds scripts, flows and apps as reviewable drafts, and runs many in parallel. Supporting work landed around it — file attachments in chat, visible web-search sources, in-app git-to-Windmill sync, and schema contracts that warn when a consumer script drifts from a producer's materialized table.

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.

A workflow engine where the AI builds the scripts and the enterprise gates come down
◆ Current state
Windmill's July stream is dominated by AI sessions, now in beta and on by default: each session ties a chat to a workspace or fork with a live preview, builds scripts, flows and apps as reviewable drafts, and runs many in parallel. Supporting work landed around it — file attachments in chat, visible web-search sources, in-app git-to-Windmill sync, and schema contracts that warn when a consumer script drifts from a producer's materialized table.
◆ Where it's heading
Two moves are running together. The authoring model is shifting from writing scripts to reviewing generated ones, with the diff drawer and draft state as the safety mechanism rather than trusting the model outright. Meanwhile the commercial line is being redrawn: BigQuery and Snowflake left the Enterprise tier for community edition, including self-hosted. Windmill is trading connector exclusivity for adoption while the AI layer becomes the thing worth paying for.
◆ Prediction
Expect AI sessions to leave beta with governance around it — who can deploy a generated draft, and what an autonomous session may touch — since the draft-and-diff design already anticipates that review step.
