Langtail

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.

Spreadsheet-style prompt editor

Build, test, and version prompts in a table-based editor that anyone comfortable with spreadsheets can use.

Automated evaluation and test runs

Add natural-language assertions, pattern matching, or custom code checks and run them over datasets to catch regressions.

Request logging and observability

Trace every request and response, inspect latency and cost, and diagnose why an LLM answered the way it did.

AI Firewall and safety checks

One-click AI Firewall blocks prompt injection, denial-of-service attempts, and information leaks with customisable content filtering and alerts.
