Open-source LLM observability platform and AI gateway for routing, monitoring, and optimizing LLM requests.

Key features

  • Request Logging and Telemetry: Captures per-request inputs, outputs, metadata, and provider responses to enable debugging, auditability, and detailed traceability across LLM calls.
  • AI Gateway (Routing & Load Balancing): A Rust-based gateway that routes requests to 100+ supported models/providers, performs load balancing, provider fallback, and abstracts multiple model APIs behind one endpoint.
  • Caching and Rate Limiting: Built-in response caching and configurable rate-limiting at the gateway level to reduce costs, improve latency, and protect provider quotas.
  • Cost and Latency Tracking: Aggregates usage metrics, cost estimates, and latency statistics per-provider and per-endpoint to help teams monitor spending and performance.
  • Prompt Management & UI Iteration: UI-driven prompt experimentation and iteration tools that let teams test, refine, and compare prompts and model outputs without code changes.
  • Agent Tracing & Evaluations: Traces agent executions and provides evaluation tooling and dashboards for automated testing, scoring, and comparison of model behaviors and datasets.
  • Deployment & Enterprise Options: Support for quick local/docker deploys and production-ready Helm charts for enterprise customers, plus commercial support channels.
  • Request logging and full LLM request/response capture
  • Caching layer to reduce upstream calls and latency
  • Rate limiting and request routing via AI gateway/proxy
  • Cost and latency tracking and analytics
  • UI-based prompt iteration and prompt management
  • Agent tracing and multi-agent workflow visualization
  • Evaluation tooling, datasets management, and fine-tuning integration
  • One-line integration / header-based instrumentation and SDKs
  • Self-hosted deployment via Docker or Helm (production Helm chart for enterprise)
  • Multiple language repos and integrations (TypeScript, Rust, Go, n8n, SDK helpers)

Best for

  • Centralized Observability for LLMs: Capture and inspect every LLM request and response in production to troubleshoot hallucinations, regressions, and unexpected behaviors.
  • Multi-Provider Routing and Failover: Route traffic across OpenAI, Anthropic, AWS Bedrock, Google Vertex and others with load balancing and automatic fallbacks to ensure reliability.
  • Cost Optimization and Monitoring: Track per-request costs and latency to identify high-spend prompts or endpoints and apply caching or alternative routing to reduce expenses.
  • Prompt Engineering Workflow: Use the UI to iterate on prompts, compare outputs across models, and version prompt templates for faster prompt engineering cycles.
  • Agent and Pipeline Tracing: Monitor multi-step agent executions and workflows to visualize step-level latency, errors, and decision points for debugging and optimization.
  • Production Hardening: Add rate limits, caching, and provider failover at the gateway layer before exposing LLM functionality to end-users to increase reliability and reduce operational risk.
  • Evaluation and Benchmarking: Run evaluations against datasets and track model performance over time to validate changes and select optimal providers or models.
  • Centralized logging and observability for applications that call LLM providers (OpenAI, AzureOpenAI, etc.)
  • Add a lightweight proxy/gateway to handle caching, rate limiting, and routing between apps and LLM providers
  • Monitor and analyze LLM cost, latency, and usage patterns across teams and environments
  • Iterate on prompts through a UI and collaborate on prompt engineering and testing
  • Trace and debug multi-agent/chain-of-thought workflows and agent interactions
  • Self-hosted enterprise deployments with Kubernetes / Helm for production LLM telemetry

qarunbook is an app testing runbook where AI drafts a test plan from your code and your team or AI works through it, tracking issues and retests.

Key features

  • AI-Drafted Test Plans: The /test-checklist skill looks through your app and drafts checks with steps and expected results already filled in.
  • MCP Connection: Connect Claude Code, Claude Desktop, Codex, Cursor or any MCP client so the assistant can read the plan and record results.
  • Issue-to-Check Linking: Every issue sits on the check that found it with the affected platforms, and raising one removes the pass.
  • Retest Flow: When an issue is fixed the check waits for someone to look again before being marked passed.
  • Roles and Join Links: Give people access to only the projects they need and invite whole groups with a join link.
  • Multi-App Workspaces: Keep each app's sections and platforms separate so web, driver and marketing sites are tested side by side.
  • GitHub and Linear Integration: Connect issue trackers so problems found in testing flow into existing engineering workflows.
  • QA Runbook Skill: The /qa-runbook skill works through the plan on web and mobile, recording each result and re-checking fixes.

Best for

  • Release Testing: Run a structured test plan before each release across web, Android and iOS.
  • AI-Assisted QA: Let a coding assistant execute checks and record pass/fail results through MCP.
  • Team Test Coordination: Split test checklists among teammates and see progress and results in one workspace.
  • Regression Follow-up: Track bugs against specific checks and retest them after fixes ship.
  • Solo Developer Testing: Generate a test plan from the codebase so a one-person team knows what to check.
  • Agency Multi-Client QA: Manage separate apps and clients with scoped access and a flat workspace price.
