Langtail

Langtail is a low-code platform built specifically to help teams test, debug, and secure AI applications powered by Large Language Models. If your team is building with LLMs, you know how challenging it can be to systematically test prompts, catch unexpected outputs, and keep the whole product, engineering, and business team aligned. Langtail solves this with a familiar spreadsheet-like interface that makes comprehensive LLM testing accessible to everyone on the team, not just engineers. It supports a wide range of LLM providers, enables cross-functional collaboration, and includes an AI Firewall to block prompt injection attacks and filter unsafe outputs — so your AI applications stay secure and reliable.
