PromptLayer

PromptLayer is a prompt management and engineering workbench designed for AI engineers and domain experts. It provides a unified platform to version control, test, evaluate, and monitor every prompt and AI agent. With PromptLayer, teams can iterate on prompts directly in the visual editor without waiting for engineers to redeploy, accelerating AI application development and optimization. The platform supports needs from individual developers to enterprise teams and is trusted by companies like Gorgias for building autonomous prompt engineering teams.

Prompt Management & Version Control

Visually edit, store, and version control prompts in the Prompt Registry. Compare multiple versions and easily track prompt evolution history to avoid configuration confusion.

A/B Testing & Comparison

Perform A/B tests directly on the platform to compare performance of different prompt versions. View usage and latency metrics to quickly identify optimal solutions.

Evaluation & Regression Testing

Evaluate prompts against historical usage data. Support model comparison, scheduled regression tests, and one-off batch runs to ensure consistent quality.

LLM Observability & Log Tracing

Complete logging and tracing capabilities help teams read execution logs, discover edge cases, identify issues, and improve prompts.

Team Collaboration & Access Control

Enable non-technical team members to participate in prompt iteration. Role-based access control (RBAC) and deployment approval workflows ensure safe and efficient collaboration.

Agent Node Execution

Support AI agent execution and monitoring with complete agent workflow management capabilities.

1. Sign Up: Visit PromptLayer website and register with email or SSO. Free accounts require no credit card.
2. Create Workspace: Set up a project workspace and invite team members to collaborate.
3. Write Prompts: Write or import existing prompts in the visual editor.
4. Version Management: Save prompt versions and the system automatically tracks changes.
5. Run Tests: Execute A/B tests or evaluations to compare different version performance.
6. View Logs: Check execution logs, errors, and performance metrics in the dashboard.
7. Deploy: Deploy optimized prompts to production after approval workflow.

Accelerate Development

No need to wait for engineers to redeploy. Non-technical team members can iterate on prompts directly in the visual editor, significantly speeding up AI application development cycles.

Data-Driven Decisions

Complete logging and evaluation tools help teams optimize prompts based on actual data rather than guesswork.

Enterprise Security & Compliance

SOC2 Type 2, GDPR, HIPAA, and CCPA certified. Enterprise customers get BAA signing, self-hosting options, and dedicated support.

Flexible Scalability

From free to enterprise plans with custom options. Support multi-cloud deployment on GCP, AWS, and Azure to meet different team sizes.

Complete Observability

Built-in LLM observability automatically tracks every request, agent execution, and evaluation result for quick issue identification.
