Langtail is a prompt management platform for product teams that lets engineers, PMs, and domain experts build, test, version, and deploy LLM prompts through a spreadsheet-like interface, with observability logs, evaluation runs, and an AI firewall for blocking prompt injection and unsafe outputs. It works across OpenAI, Anthropic, Gemini, Mistral, and other major providers.

面向生产级 AI 的智能体可观测性、评估与持续改进平台
基于 OpenTelemetry 之上的 OpenInference 规范，采集智能体与 LLM 调用的 span、trace 和会话，埋点可跨工具复用。
在 span、trace 与会话三个层级运行评估，对海量生产数据衡量检索质量、工具调用与最终回答的优劣。
内置于产品中的智能体，可检查链路、推断根因，并给出供工程师上线前审阅的修复建议。
当需要让轨迹数据留在自有基础设施内时，可自行部署这一领先的开源追踪与评估工具。

It works across OpenAI, Anthropic, Gemini, Mistral, and other major providers.
Build, test, and version prompts in a table-based editor that anyone comfortable with spreadsheets can use.
Add natural-language assertions, pattern matching, or custom code checks and run them over datasets to catch regressions.
Trace every request and response, inspect latency and cost, and diagnose why an LLM answered the way it did.
One-click AI Firewall blocks prompt injection, denial-of-service attempts, and information leaks with customisable content filtering and alerts.
