Humanloop
LLMOps platform for prompt management evaluation and human feedback with SDKs and a collaborative dashboard for product teams.
Overview
Humanloop helps teams build reliable LLM features by organizing prompts, datasets and feedback in one workflow. Product managers and engineers compare prompt variants and models, log production traffic, and review failure cases to improve quality. Evaluation runs combine automatic metrics with rubric based human reviews so you can quantify regressions before release.
The SDKs and proxy capture traces and latencies without heavy code changes, and the dashboard turns raw events into actionable insights for ranking and approval. Humanloop integrates with major model providers and vector stores, and supports environments and versioning so rollbacks are simple. Plans include a free tier for small projects with paid options for higher volumes and enterprise controls.
Teams choose it when experimentation has outgrown notebooks and they need a shared place to govern prompts and data in production.

Combine metrics with rubric grading so you catch regressions before release.
Traces and latency
Capture production traffic to spot failures latency spikes and drift.
Roles and versions
Control approvals and rollbacks so changes are safe and auditable.
Frequently Asked Questions
Is there a free plan?
Yes, materials describe a free tier for small projects with paid plans for higher volumes and enterprise needs.
Which models are supported?
Integrations include major providers and vector stores so you can test choices side by side.
Do I have to refactor my app?
SDKs and a proxy capture traces with minimal code changes and help route experiments.
Can non engineers review outputs?
Yes, rubric based reviews and dashboards let PMs and QA grade results collaboratively.
How do teams justify ROI?
Dashboards track quality latency and cost so leaders see impact before and after changes.
