PromptLayer

Freemium

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.
