GridKeeper, a Memory for Slack Security

gridkeeper.app Observed source
Editorial interest 82/100 Selection signal · not a rating of the site

A read-only monitor that tracks changes to a Slack workspace’s security posture over time.

Landing page captured for the 2026-08-24 issue.

Field notes

GridKeeper establishes a full workspace baseline, then compares scheduled checks against the previous state so administrators see changes rather than repeatedly reviewing unchanged settings. Its stated coverage includes identity, app scopes, sharing defaults, guest expiration, and Slack Connect exposure. The page illustrates the output with a change from one of two owners or administrators to two of two, plus an app holding sensitive scopes. It also states that the service never reads message content and requests no history scope.
