What’s new in Kiln.

Guardrails can now watch any metric from your warehouse, not just APM data. Define a SQL query, set a threshold per rollout step, and Kiln does the rest.

We moved flag evaluation to 38 new edge regions. Median evaluation latency dropped from 6.4 ms to 3.1 ms worldwide.

Pick a date, a time zone and a target percentage. Kiln releases while you sleep and posts a summary to Slack in the morning.

Approvals now correctly re-request review when a rule changes after sign-off, and reviewers can no longer approve their own changes.

Native mobile SDKs with offline caching, real-time updates over a single socket and full OpenFeature support.
