Open-source LLM prompt management and observability platform

Code & DevelopmentFreemium

Pezzo is an open-source LLM operations platform focused on prompt management, versioning, and observability. Teams can design prompts in Pezzo's visual editor, publish versioned prompt releases, and consume them via API — separating prompt engineering from application deployment. Pezzo's observability layer tracks every LLM request with cost, latency, and quality metrics, making it easy to audit AI behavior and optimize spending.
