Latitude is an open-source platform designed to streamline the entire lifecycle of AI prompt engineering, from development and testing to deployment and evaluation. It empowers cross-functional teams, including developers, product managers, and domain experts, to build, maintain, and refine reliable AI applications collaboratively.

How It Works

Latitude provides a comprehensive suite of tools for prompt management, including a collaborative editor with advanced features like variables and loops (PromptL). Prompts can be interactively tested in a playground, deployed as versioned API endpoints via an AI Gateway, and systematically evaluated using LLM-as-judge, programmatic rules, or human review. Automatic logging captures all interactions, facilitating observability and performance monitoring.

Quick Start & Requirements

Latitude offers two deployment options:
