Enprompta – Prompt Registry, LLM Evals, and Observability for Production AI Apps
Enprompta is an evaluation and observability platform for AI teams, enabling LLM call tracing, automated evals, and prompt iteration in production without redeployment.
Ship better AI, every time
Enprompta is the evaluation and observability platform for AI teams. Trace LLM calls, run automated evals, and iterate on prompts in production—so every release improves, not regresses.

Three ways to get started
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.
One OTLP endpoint — repoint your exporter
Every call, with cost & latency
Works with OpenTelemetry, OpenInference & OpenLLMetry

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.
Simple-rule or AI-grader (LLM-as-judge) scoring
Agentic & trajectory checks for multi-step agents
Runs in CI and live on production traffic

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.

Close the loop on AI quality
Observe what's happening in production, measure it with evals, and iterate—without redeploying.
Observability
Trace every LLM call in production. Inspect inputs, outputs, latency, tokens, and cost per request.
Evaluations
Score quality with rule-based checks and LLM-as-judge — in CI and continuously on production traffic. Catch regressions before users do.
Prompt Iteration
Version, branch, and update prompts at runtime via the SDK—no redeploy.

Observability
Why did the AI say that?
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.

Multi-LLM Testing
Run the same prompt across OpenAI, Anthropic, Google, Mistral and more. Compare outputs side by side.
Datasets
Curate test data from real production traces and run your evals against it.
