Raindrop

Raindrop is an observability platform for AI agents. It traces every agent run in production, detects silent failures that do not raise errors, helps teams investigate what went wrong, and simulates changes in continuous integration before they ship. The site compares its role to a crash reporter such as Sentry, but for AI capabilities. Its experiments feature compares two cohorts of logged events, a baseline and an experiment, across date ranges, models, prompt versions or feature flag variants, and reports the change in signal rates with a 95 percent confidence interval. Users can ask its Triage assistant questions in the app or in Slack, and experiments can also be created and read through MCP. Teams building agents and AI companion apps use it to keep issue rates below a chosen threshold and to spot spikes. The site offers a free start with no credit card, and a demo can be booked. Creating and editing experiments requires the Pro plan. Prices for the paid plans are not published on the pages the site presents.
