Product updates, engineering notes, and infrastructure insights.
We rewrote the check scheduler in Rust, reducing per-check memory usage by 62% and improving check throughput by 3.5×. Agents now handle 10,000+ concurrent checks on a single CPU core.
Alerts now group related incidents automatically. Instead of 50 emails when a datacenter goes down, you get one summary with a root cause analysis hint. Less noise, faster resolution.
After 12 months of audits, Stack is now SOC 2 Type II compliant. All customer data is encrypted at rest and in transit, with full audit trail for every action in the platform.
You can now define arbitrary webhook targets per alert rule — not just Slack and PagerDuty. Plus, the new Terraform provider lets you manage Stack configuration as code.
