Raindrop

Raindrop is a monitoring and observability platform for detecting, tracking, and fixing issues in AI agents, used by engineering teams at Speak, Vercel, Clay, Framer, and AngelList, processing billions of traces monthly for Fortune 100 customers. It captures every agent message, tool call, retry, and error in one place through Trace Inspection, automatically detects silent failures like hallucinations, loops, and broken tools with Slack alerts, and lets teams triage issues and ask questions directly in Slack. Its Experiments feature runs A/B tests with feature flags to validate fixes, Signals provides custom classifiers for specific agent behaviors, and Workshop is an open-source local development tool for debugging. Raindrop is SOC 2 compliant with PII redaction and enterprise access controls. The Hobby tier is free for 1,000 events per month; Pro is $299/month with a 14-day free trial, covering 1 million events at $0.003 each and $0.002 per event after; Enterprise offers custom pricing with audit logs, SSO, and SLA guarantees.
