Sonarly

Sonarly is a Y Combinator-backed company that makes software self-healing. The company participated in the Winter 2026 batch of Y Combinator.

We want software to improve itself.

Sonarly connects to your monitoring stack - tools like Sentry, Datadog, and Grafana - and triages every alert to remove noise and duplicates. It then investigates logs, traces, metrics, and code to build a living map of your production system and find root cause. The result is either a ready-to-merge fix PR or a recommendation to update your alerting rules so the noise never comes back.

Sonarly was part of Y Combinator's Winter 2026 cohort, has a team of approximately 2 employees, and is actively operating.
