What is Langtail?

Langtail is a prompt management platform for product, engineering, and business teams working with large language models. It offers a spreadsheet-like interface to create, test, and validate prompts using natural language evaluation, pattern matching, or custom code, with version control and collaborative workflows. Users can experiment with models and parameters, review prompt performance, and deploy prompts to production through a TypeScript SDK and OpenAPI. An AI Firewall blocks prompt injections and unsafe outputs, and self-hosting is available for data control. It works with OpenAI, Anthropic, Gemini, Mistral, and other providers, and is sold with a free trial and paid plans.
