Lunary for Web

Overview

Lunary is an open-source platform built to streamline the development and maintenance of large language model (LLM) applications. It focuses on giving teams practical tools to observe runtime behavior, fix issues faster, and iterate on models and prompts with measurable feedback.

Primary capabilities

• Real-time alerts for anomalous outputs and runtime failures to surface problems quickly.
• Detailed logs and debugging aids for agent interactions, making it easier to reproduce and label problematic exchanges for model improvement.
• Cost analytics broken down by individual users and by model so teams can control spending and allocate resources efficiently.
• Full-featured API access and powerful search utilities to speed up integration and debugging workflows.
• Session recording of user–bot conversations to uncover knowledge gaps and recurring misunderstandings.
• Collaborative prompt templates and workflow features that let non-engineers contribute to prompt design and testing.
• Options for hosting the platform on your own infrastructure along with features aimed at satisfying data-protection requirements.
• An active community-driven project model that encourages contributions and extensions from external developers.

Collaboration and prompt management

Lunary supports shared prompt libraries and editing workflows that let product managers, designers, and other non-technical stakeholders work alongside engineers. Templates can be versioned and iterated on, so teams can experiment with prompts while keeping a clear audit trail.

Observability and cost control

The platform combines tracing tools and labeled examples to make debugging LLM agents straightforward. Built-in cost breakdowns by user and model help teams spot inefficiencies and tune usage patterns to reduce expenses.

Deployment and compliance

You can run Lunary in a self-hosted environment for greater control over data residency and access. It also includes compliance-oriented features to help meet organizational security and privacy standards.
