## About PromptLayer
PromptLayer is the AI layer for engineering teams that need to build, manage, and evaluate LLM-powered products at scale, while giving non-technical stakeholders a seat at the table. At its core, PromptLayer is a Registry that decouples prompts and skill files from code. Engineers pull prompts programmatically at runtime via the API or SDK, while PMs, domain experts, and QA teams can iterate on templates directly in the platform without touching the codebase. Every change is versioned, committed with a message, and auditable. Release labels let you control what hits production without a code deploy. For teams building more complex workflows, the visual agent editor lets you chain multiple LLM calls together with conditional logic, looping, external API callbacks, and parallel execution, all without managing infrastructure. Agents are versioned, deployable via API, and fully traceable in the observability layer. Observability gives you full visibility into every LLM call in production: traces, token usage, latency, and cost across prompts and models. You can tag requests with metadata, score outputs, and run A/B tests across prompt versions using dynamic release labels. Evals are built into the workflow. Run synthetic evaluations using LLMs as judges, collect user feedback scores, or build structured evaluation reports from production logs and curated datasets. Prompt A vs. Prompt B comparisons are native to the platform. Reusable Skills let teams package prompt logic into modular, versioned building blocks that can be shared across projects and pulled into agent workflows or coding environments like Claude Code. Enterprise controls include RBAC with custom roles and workspace-level permissions, SSO, audit logging, and a self-hosted deployment option for teams with strict data residency or security requirements. PromptLayer integrates with every major model provider and works alongside existing observability tools. PromptLayer is model-agnostic and horizontally applicable, used across ML, product, legal, clinical, and operations teams. The core value is a single collaborative system where engineers ship fast and non-technical stakeholders can contribute, evaluate, and improve AI outputs without waiting on an engineering queue.
