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.

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.
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.
