### [Flyctl meets JSON](https://yomu.fyi/post/flyctl-meets-json.md)

Flyctl adds a --json, or -j, flag that presents command output as JSON to support automation around Fly applications. For GraphQL-backed commands it emits the API data, while logs become structured JSON and deployment progress arrives as a stream of Source/Status/Message objects. The post demonstrates piping flyctl list apps --json through jq to filter fields, convert hostnames and statuses to CSV, and select undeployed apps whose names feed xargs flyctl info --json -a; jq -s then gathers the resulting objects into an array. Because deployment output currently mixes JSON with non-JSON messages, the post recommends using --detach and polling flyctl status or running flyctl monitor instead of relying on the JSON stream for deployment monitoring.
