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)
- Token usage tracking and AI spend monitoring with per-request and aggregated metrics
- Cost attribution to features, workflows, or customers
- Prompt/version management: template retrieval, listing, publishing, and cache invalidation
- Prompt/agent evaluation tooling, regression sets and replay capabilities
- SDKs for Node.js and Python with async support and promise-style or async methods
- Client methods: run/runWorkflow (helpers), logRequest (manual logging), track (annotations/metadata/scores/groups), group creation, wrapWithSpan/traceable decorator for instrumenting code
- Provider proxy wrappers for OpenAI and Anthropic that automatically log and trace requests
- OpenTelemetry integration and OTLP/HTTP ingestion for third-party tracing sources
- Plugins: Claude Code tracing plugin and OpenClaw observability plugin (exports OpenClaw activity as OTEL GenAI traces)
- Self-hosted deployment: dockerized services (frontend, Python Flask backend API), PostgreSQL v15, object storage support (Amazon S3, Google Cloud Storage), Redis/Valkey v8.1.0
- Environment-driven configuration with API key and base URL overrides
Best for
- Cost Attribution: Measure token consumption and AI spend per feature, endpoint, or customer to allocate costs accurately and identify expensive usage patterns.
- Debugging Multi-Step Agents: Trace multi-step agent runs and tool invocations to visualize execution flow, inspect intermediate responses, and diagnose failures or hallucinations.
- Prompt Regression Testing: Store historical prompts and responses to create regression sets and run comparisons when upgrading models or altering prompts to ensure behavior stability.
- Centralized Observability: Consolidate LLM requests, traces, and metrics from multiple providers (OpenAI, Anthropic, Claude) into a single dashboard for unified monitoring and alerts.
- Compliance & Self-Hosting: Deploy a self-hosted instance to retain full control of prompt data and meet enterprise compliance requirements (SOC 2, HIPAA, GDPR).
- Integration with Tracing Pipelines: Export GenAI semantic traces via OpenTelemetry plugins to integrate prompt traces with existing distributed tracing and APM systems.
- Trace and debug complex multi-step LLM workflows and agent executions
- Monitor token consumption and AI spend per feature, customer, or environment
- Version, test and regress prompts and agent behaviors across releases
- Integrate LLM telemetry into existing observability stacks via OpenTelemetry/OTLP
- Self-hosted deployments for compliance (SOC 2, HIPAA, GDPR) and data residency requirements
- Automatically capture Claude Code sessions and OpenClaw agent runs as structured traces
