PromptLayer

PromptLayer is a platform for versioning, testing, and monitoring prompts and agents. It provides a visual editor for prompt management, A/B testing, deployment, and evaluation. The platform enables collaboration between technical and non-technical team members, allowing domain experts to iterate on prompts directly without waiting on engineering redeploys. PromptLayer supports prompt versioning with comments, notes, diffs, and rollbacks. It includes evaluation capabilities such as historical backtests, regression tests, model comparison, and one-off batch runs. The platform also offers monitoring features for cost, latency, and usage statistics, and supports building and tracing agent workflows with tool calls, evaluations, and logs. It is model agnostic, working with models like Claude, Gemini, Hugging Face, Cohere, Mistral AI, and ChatGPT. PromptLayer is SOC 2 Type 2, HIPAA, and GDPR compliant.
