Raindrop

The product is an agent observability and monitoring platform that logs every production agent run including messages, tool calls, retries and errors, and automatically detects silent failures such as hallucinations, loops and broken tools. It is for developers and engineering teams building and operating AI agents, including enterprise teams. Compared to alternatives such as Braintrust, LangSmith and Arize that focus on call/response and deterministic evals, it is positioned for proactively finding issues and driving automatic improvement loops.
