Lune.dev - 2026 Pricing, Features, Reviews & Alternatives

Lune.dev is a cloud-based platform that provides software developers and technical users with access to a community-driven library of topic-specific AI models, called Lunes. Each Lune is a retrieval-augmented model trained on user-defined knowledge sources, including GitHub repositories, official documentation, API references, guides, and blog posts. An AI agent called Tycho automatically infers context from user queries and switches between relevant Lunes to deliver documentation-grounded answers with cited references. Developers can interact via a web interface or integrate directly into coding environments such as Cursor and Continue through an OpenAI-compatible API that functions as a drop-in replacement for existing OpenAI endpoints.

The platform supports creation of custom Lunes from one or multiple knowledge sources, enabling developers and open-source contributors to build and share expert models around specific libraries, frameworks, and tools. Automatic model routing selects between underlying large language models depending on task requirements, such as structured output generation. Lunes self-update from connected knowledge sources over time to maintain accuracy. Conversation continuity is preserved across IDE and web interfaces, and the platform supports MCP servers inside tools such as Cursor and Claude Desktop.

Lune.dev targets software developers, open-source contributors, and teams working in AI-assisted coding environments who require accurate, source-cited answers to technical questions. The platform covers industries including software development, open-source tooling, and developer tooling, and provides access to hundreds of community-created Lunes spanning a wide range of technical domains.
