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.

Description

LangProtect serves as a cutting-edge security and governance platform specifically designed for AI, offering robust protection against issues such as prompt injections, jailbreaks, data leaks, and the generation of unsafe or non-compliant outputs in LLM and Generative AI applications. Tailored for production-grade GenAI environments, this platform implements real-time controls at the execution level of AI, meticulously examining prompts, model outputs, and function calls as they occur, enabling teams to intercept high-risk actions before they can affect end users or compromise sensitive information. By doing so, LangProtect ensures that potential threats are neutralized promptly, preserving the integrity of data and user interactions. Furthermore, LangProtect seamlessly integrates with existing LLM infrastructures through an API-first design that maintains low latency, accommodating various deployment models including cloud, hybrid, and on-premise solutions to meet the security and data residency requirements of enterprises.
