What is Sonarly?

Sonarly is an AI-powered engineering analytics platform that makes software self-healing. Part of YC W2026, the company was founded in 2025 by Dimittri Choudhury and Alexandre Klobb — both previously co-founded a career-guidance app that scaled to 100K+ users in France. Sonarly has already achieved over $300K ARR, reaching its Demo Day goal a week early.

The platform connects to your existing observability stack (Sentry, Datadog, Grafana) and communication channels (Slack, Discord), then acts as an autonomous AI on-call engineer. It deduplicates alert noise — in one case study reducing 180 alerts/day down to ~5 actionable issues — investigates root causes using logs, traces, metrics, and code context, and autonomously ships PR fixes when confidence is above threshold. The system continuously updates its understanding of your production environment after each alert, improving accuracy over time.

Powered by Claude Code, Sonarly operates 24/7 as a virtual SRE that triages, debugs, and fixes production issues without human intervention. The platform offers self-serve onboarding in 2-3 minutes through native OAuth integrations with monitoring tools, requiring no changes to your existing stack.

Using Sonarly with Respan

Sonarly autonomously fixes production issues detected through observability tools, while Respan provides the LLM-specific observability layer. For AI-powered applications, Respan can surface LLM-related issues that Sonarly can then investigate and fix.
