What does Langbase do?

Langbase is a serverless platform designed for developers who want to build and run AI agents. It provides the infrastructure to create applications that use large language models, connect to tools and data, and then deploy them at scale. Instead of wrestling with backend complexity, you can focus on the agent logic. The platform abstracts the underlying infrastructure, offering a unified way to work with hundreds of different LLMs through a single API.

What makes Langbase stand out is its focus on core developer primitives. Its 'Agents' feature lets you pick any supported LLM and connect it to tools. The 'Memory' system is a built-in, agentic RAG (Retrieval-Augmented Generation) API that handles vector storage and retrieval, allowing you to chat with your documents or code repositories. You can build these agents in a visual studio or directly with code, and deployment is handled serverlessly.

This tool is most useful for developers and engineering teams building production AI applications, such as customer support assistants, internal knowledge chatbots, or any automated agent that needs to reason and act on data. It removes the heavy lifting of model orchestration, data pipeline management, and deployment, letting teams ship AI features faster.
