Sonarly: Makes software self-healing

Makes software self-healing

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.

Two years ago, I moved from a random village in France to Paris to study CS. I started building my first startup with Alex and we scaled it to 100k+ users in 6 months. It's funny because it was the Duolingo for finding schools and it made us drop out. Now we're building Sonarly (YC W26), giving coding agents the context they need to fix production bugs automatically.

I started freelancing at 15 doing web scraping, then quickly became a full-stack developer and later an AI engineer training ML and deep learning models. I dropped out of computer science school to co-found Meoria, a career-guidance app that helped over 100,000 French students navigate Parcoursup but the market moved too slow for our ambition. Now I’m building Sonarly: the platform that instantly detects and fixes production bugs before your users ever notice them.

Sonarly: The AI engineer for production

See original launch post

Hey! 👋 We're Dimittri and Alexandre and we're building Sonarly - an AI engineer that lives in your production stack, connecting to tools like Sentry, Datadog, and your user feedback channels. It triages alerts, investigates root causes, and ships fixes automatically.

The Problem: The high cost of MTTR

Each bug in production is a frustrated user, and the longer the bug is there, the more likely the user is to churn. But if an issue is resolved fast, it can actually improve user happiness: they see that the team cares about them.

But this Time to Repair is inflated by two main bottlenecks:

1 - Noisy alerts make it slower to find the real signal. Alert fatigue is the first barrier.

2 - The waiting game. Once we have a clear signal, the longest step is fixing the bug. You have to find an on-call engineer, wait for them to wake up, or wait for them to finish another task. This time is precious and should be used to start the investigation. Once available, the on-call engineer has to dig through production logs and metrics, often going back and forth with Claude Code because the solution isn't obvious.

The core issue is that coding agents are very good at building software, but they struggle at run time because they lack context.

The Solution: The proactive coding agent with production context

We're building Sonarly to help you do one thing: make something people want. Right now, they want to use your product, but it's broken. We cut your resolution time so they can get back to using it.

Sonarly acts as an autonomous on-call engineer that works in the background 24/7. We're not replacing the on-call engineer, but we're helping them find the signal in the noise and saving them precious hours of investigation.

We connect to your entire monitoring stack, from Sentry & Datadog to user bug reports on Slack & Discord (+ many more integrations).

What it does:

1- Trust your alerts: We triage signals together to group duplicates and filter false positives, sending only actionable alerts to your Slack or Email.

2 - Fix with Context: We run a coding agent in the background to investigate and fix bugs using the context of your whole production system: logs, traces, metrics, user feedback, and code.

3 - Continuous Learning: We update the representation of this system after every alert. This ensures the context is always up-to-date, so our agent understands your system better and fixes issues faster.
