PromptLayer
PromptLayer
Token-economics and observability platform to trace requests, monitor token usage and AI spend, and debug LLM workflows from one dashboard.
Key features
- Request Tracing: Captures structured traces for prompts, model inputs/outputs, tool calls and multi-step agent execution to visualize end-to-end LLM workflows and identify failure points.
- Token & Spend Analytics: Aggregates token usage and monetary spend across requests, models, features, and customers to enable cost attribution, budgeting, and optimization.
- Provider Proxies & SDKs: Official Python and Node.js SDKs and provider proxy wrappers (OpenAI, Anthropic, etc.) that automatically log requests, responses, and metadata for minimal instrumentation effort.
- Workflows & Replay: Helpers for running and replaying prompts and multi-step workflows, enabling regression testing, deterministic re-runs, and comparison of outputs across model versions.
- OpenTelemetry & Plugin Integrations: OTLP-compatible integrations and plugins (e.g., OpenClaw, Claude plugins) to export GenAI semantic traces and integrate with distributed tracing pipelines.
- Grouping, Annotation & Evaluation: Request grouping, metadata tagging, and robust evaluation/regression sets to organize requests, annotate outcomes, and track prompt performance over time.
- Self-Hosted Deployment: Full self-hosted stack (dockerized services with PostgreSQL, object storage, Redis) for teams needing on-prem data control, SOC 2/HIPAA/GDPR alignment and compliance.
- Request tracing and distributed traces for multi-step LLM workflows (OTLP/HTTP JSON compatible)
