Description

LangFast is a streamlined prompt testing platform aimed at product teams, prompt engineers, and developers working with large language models. It offers immediate access to a customizable prompt playground without requiring signup, making prompt experimentation quick and hassle-free.

Developed by a team experienced in scaling AI SaaS products to millions of users, LangFast provides full control over the prompt development lifecycle. The platform also fosters improved team collaboration by enabling easy sharing and iteration. Its pay-as-you-go pricing ensures users only pay for what they use, keeping budgets under control.
