Raindrop Workshop

Raindrop Workshop is the open-source debugger every AI agent developer has been screaming for. It's free, runs locally on your machine (localhost:5899), and gives you real-time visibility into what your agents are actually doing—including the parts they'd rather you didn't see. Silent failures? Tool errors? Abnormal trajectories? Raindrop catches all of it. No more flying blind through agent executions.

Think of it as observability for AI agents done right. You get span trees, execution trajectories, timing data ($0.032 per call matters when you're optimizing costs), and communication graphs. It shows you exactly which tools fired, how long they took, and what your agent was actually thinking. There's a reason they're trusted by "the fastest growing AI companies"—when your agent breaks in production at 2am, you need Raindrop, not a console full of generic errors.

They've got case studies. They're hiring. And unlike every other "AI developer tool" that charges per API call, Raindrop is free because they believe debugging should be accessible—not paywalled.
