Sonarly

Sonarly is an AI production-reliability platform (Y Combinator W2026, Paris) that turns noisy production alerts into clear, deduplicated bug reports and ships ready-to-merge fix pull requests. It connects to a team's code (GitHub/GitLab) and their error and observability stack — Sentry, Datadog, Grafana, New Relic, SigNoz, CloudWatch, GCP, and many more — then triages every alert to remove noise and duplicates, investigates logs, traces and metrics to find the root cause, and generates a fix PR or alerting-rule recommendation. Sonarly exposes a read-only public REST API (v1) for pulling bugs, incidents and analysis runs into custom dashboards, signed outbound webhooks for live events, and a device-code style setup-session API that lets a coding agent (Claude Code, Cursor) onboard a tenant end-to-end. Onboarding is fully agent-native and documented at sonarly.com/llms.txt.

Sonarly publishes 3 APIs on the APIs.io network: Bugs API, Incidents API, and Setup API. Tagged areas include Company, Reliability, Observability, Monitoring, and Bug Detection.

The Sonarly catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Sonarly’s developer surface includes documentation, API reference, authentication, pricing, signup flow, and 16 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/sonarly: open an issue to ask a question, or submit a pull request to add artifacts.
