Three ways to get started<br>Watch what your AI does in production, catch bad answers before they ship, or fix a live prompt without a redeploy — start wherever your team needs. Built for the engineers who ship it and the product people who read the answers.
See what your AI is doing
See every call your app makes to an AI — in development or production. Set two environment variables and you're live. Already using OpenTelemetry? Just point it at us — no new SDK, no lock-in.<br>One OTLP endpoint — repoint your exporter<br>Every call, with cost & latency<br>Works with OpenTelemetry, OpenInference & OpenLLMetry<br>View tracing docs
Catch bad answers before users do
Automatically score every answer for quality, safety, and accuracy — with simple rules or an AI grader. Run checks before you ship, then keep scoring live traffic, so a bad release never reaches your users.<br>Simple-rule or AI-grader (LLM-as-judge) scoring<br>Agentic & trajectory checks for multi-step agents<br>Runs in CI and live on production traffic<br>Create account
Fix a prompt without a redeploy
Keep every prompt in one versioned registry, and let your app pull the latest version at runtime. Improve or roll back a live prompt in seconds — no code change, no deploy, no waiting on engineering.<br>Versioned prompt registry<br>Runtime serving via SDK<br>Review, collaborate & roll back<br>Browse SDK docs
Just experimenting? The free browser extension improves prompts in ChatGPT, Claude & Gemini — no account needed.
Close the loop on AI quality<br>Observe what's happening in production, measure it with evals, and iterate—without redeploying.
Observability<br>Trace every LLM call in production. Inspect inputs, outputs, latency, tokens, and cost per request.
Evaluations<br>Score quality with rule-based checks and LLM-as-judge — in CI and continuously on production traffic. Catch regressions before users do.
Prompt Iteration<br>Version, branch, and update prompts at runtime via the SDK—no redeploy.

Observability<br>Why did the AI say that?<br>See exactly what happened on any request — the input, the answer, how long it took, the tokens it used, and what it cost. Debug a bad answer in seconds instead of guessing.<br>Execution tracesLatency trackingToken usageCost attributionError logs
Multi-LLM Testing<br>Run the same prompt across OpenAI, Anthropic, Google, Mistral and more. Compare outputs side by side.
Datasets<br>Curate test data from real production traces and run your evals against it.
Dynamic Variables<br>Use {{variables}} for flexible, reusable prompts.
REST API<br>55+ endpoints. Webhooks. Full programmatic access.
Browser Extension<br>Improve prompts in ChatGPT, Claude & Gemini — the free solo on-ramp.
