Sonarly is an AI-powered production engineering platform that connects to existing monitoring infrastructure and autonomously handles the alert-to-fix pipeline that traditionally consumes significant engineering time. When a production alert fires in Sentry, Datadog, or other monitoring tools, Sonarly ingests the alert context, correlates it with related signals, and identifies the root cause. For issues it can resolve, it generates a ready-to-merge pull request with the fix; for optimization opportunities, it provides detailed recommendations with expected impact.
The platform excels at reducing alert fatigue by deduplicating related alerts into single root-cause incidents. Rather than an on-call engineer receiving dozens of alerts that all stem from the same underlying issue, Sonarly groups them automatically and presents a unified view with the common cause identified. This dramatically reduces the cognitive load on engineering teams during incidents and ensures that the actual problem gets addressed rather than symptoms being treated individually across multiple alert channels.
Founded by Dimittri Choudhury and Alexandre Klobb, Sonarly emerged from YC's Winter 2026 batch and builds on Claude APIs for its code understanding and fix generation capabilities. The platform targets engineering teams that want to reduce mean time to resolution without hiring additional on-call staff, offering an AI teammate that handles the routine investigation and triage work that accounts for the majority of incident response time. Sonarly integrates with GitHub for pull request delivery and standard monitoring stacks for alert ingestion.
