Enterprise tooling for LLM evaluation and prompt management

Humanloop is an enterprise LLM evaluation platform for teams building AI features. Its core product areas are evaluation, prompt management, and observability, which are designed to work together in a fast feedback loop from development through production.

The platform supports both UI-first and code-first workflows so engineers, product managers, and domain experts can collaborate on prompt engineering, testing, monitoring, and iteration. The docs describe it as tooling for developing robust AI features with LLMs, and the pricing page presents enterprise options alongside a free trial and deployment choices for larger teams.

Core capabilities

Evaluation workflows

Evaluate model changes with code, human, or AI evaluators, including LLM-as-a-judge workflows and external evaluators tailored to a business context.

Prompt management

Manage prompts in a collaborative workspace with versioning, rollback, and deployment controls, so teams can track changes over time.

Experiment comparison

Run experiments, compare results, and inspect performance issues in the UI to understand how model changes affect outputs.

Observability and feedback

Collect logs, feedback, and human judgments from applications and evaluations to monitor behavior in production and close the feedback loop.

CI/CD integration

Integrate evaluations into CI/CD and use version-controlled datasets to detect regressions before they reach production.

Collaborative workflows

Support UI-first and code-first workflows so engineers, PMs, and subject matter experts can collaborate in the same platform.

Practical use cases

Test changes before release
Benchmark new model or prompt changes against existing behavior, compare results in the UI, and use evaluators to decide whether a change is ready to ship.
Collaborative prompt iteration
Let engineers and domain experts review prompts in a shared workspace, track history, and roll back changes when a prompt underperforms.
Regression detection in delivery pipelines
Add automated evaluation checks to CI/CD with version-controlled datasets to catch regressions before they reach production.
Production monitoring and feedback
Monitor production outputs with logs, feedback, and human judgments so teams can trace issues and improve prompts or models after release.
Cross-functional AI development
Use the platform to support teams that need both a UI for non-technical contributors and code-based workflows for engineering implementation.

Pros and Cons

Pros

Combines evaluation, prompt management, and observability in one platform.
Supports both UI-first and code-first workflows for mixed technical and non-technical teams.
Includes code, human, and AI evaluators, plus support for external evaluators.
Offers collaborative prompt versioning and rollback controls.
Provides enterprise-oriented deployment and support options, including SSO/SAML, RBAC, VPC deployment add-on, and hands-on support.

Cons

The public docs state that the platform will be sunset on September 8, 2025, so it is not a long-term option for new adoption.
The source materials do not provide complete integration coverage, so some deployment and workflow details are only partially documented here.

FAQ

What is Humanloop?

Humanloop is an LLM evals platform for enterprises. It brings together evaluation, prompt management, and observability so teams can develop, test, and monitor AI features in one place.

Who is Humanloop for?

The platform is designed for both engineers and product managers or domain experts. The docs describe both UI-first and code-first workflows so different team members can work on prompts and evaluations together.

What does Humanloop log?

Humanloop says a log is created for each call to a Prompt, Tool, Evaluator, or Flow. Logs capture inputs, outputs, metadata, and related feedback or judgments.

Can I export my data from Humanloop?

Humanloop says customers can export their data at any time. The docs also note that the platform will be sunset on September 8, 2025, and point users to the Migration Guide for exports.

Does Humanloop offer a trial or enterprise plan?

Humanloop offers a free trial with access to the features in the selected plan, subject to log and evaluation volume limits. The pricing page also includes enterprise options, VPC deployment add-ons, and contact sales for tailored plans.
