Raindrop

Raindrop is the monitoring and observability platform for AI agents — a "Sentry for AI agents" that discovers silent agent failures in production. AI engineering teams use Raindrop to detect when agents fail, loop, hallucinate, or misbehave; run semantic and keyword Deep Search across millions of agent events; define custom behaviors to track in natural language; get Slack, email, and webhook alerts; inspect step-by-step traces to root-cause issues; and A/B test prompts, models, tool calls, and feature flags with Experiments. Raindrop ships first-party SDKs (TypeScript, Python, Go, Rust beta, Java beta, browser), an ingest HTTP API, a read-only Query API, a hosted MCP server, open-source Agent Skills, and the open-source Workshop local agent debugger. Founded in 2023 and headquartered in San Francisco, Raindrop raised a $15M seed led by Lightspeed Venture Partners in December 2025.

Raindrop publishes 2 APIs on the APIs.io network. Tagged areas include Company, Artificial Intelligence, Agents, Observability, and Monitoring.

Raindrop’s developer surface includes documentation, API reference, getting-started guide, authentication, CLI, engineering blog, support, and 22 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

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/raindrop: open an issue to ask a question, or submit a pull request to add artifacts.
