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. Users can create, test, and share prompt templates using Jinja2 syntax, while receiving real-time raw outputs directly from the LLM, avoiding complicated API layers. This reduces the friction typically associated with manual prompt testing, allowing teams to validate and iterate faster. 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. LangFast is ideal for teams seeking a flexible, cost-effective solution for prompt engineering.
