## 概览

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.

## 定价与套餐

Free tier of $0/month with unlimited users, 2 prompts or assistants, 1,000 logs per month, and 30 days of data retention. Pro is $99/month for a single user with 20 prompts, unlimited logs, 90-day retention. Team is $499/month for 10 users with unlimited prompts, unlimited logs, one-year retention, and Radars & Alerts. Enterprise is custom and adds the AI Firewall, self-hosting, and dedicated support. Prices exclude VAT.

## 关键功能与能力

- **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.
- **Multi-provider support and versioning:** Compare OpenAI, Anthropic, Gemini, Mistral and more, and roll out prompt changes through versioned environments.

## 主要用例

- **Shipping prompts safely (AI product engineer):** Keep staging and production prompts in versioned environments with evaluation gates before release, instead of editing strings in code.
- **Iterating on prompt quality (Prompt engineer):** Tune responses and cost by comparing models and parameters in a shared interface, then writing the winning version back to the codebase.
- **Hardening an LLM feature (Platform or security lead):** Add the AI Firewall in front of a customer-facing chatbot to block injection attempts and get alerts on unusual traffic.
- **Debugging a misbehaving assistant (QA or support engineer):** Review logged conversations, group failures, and turn recurring issues into automated evaluation checks that run on every change.

## 优势

- Non-developers can manage prompts without touching the codebase
- Evaluation and log inspection live alongside prompt editing
- Works across all major LLM providers, avoiding lock-in
- Self-hosting on Enterprise answers strict data-control requirements

## 局限

- Pro plan supports only a single user, so small teams may need the pricier Team tier
- Log limits and retention windows differ sharply between tiers
- Feature depth is aimed at production teams rather than one-off prompt experiments
- Self-hosting and the AI Firewall sit behind the Enterprise plan
