LLMStack overview

What is LLMStack?

LLMStack is an open-source, low-code platform for building, deploying, and managing generative AI applications, chatbots, and multi-step AI agents. It supports chaining multiple large language models, connecting to external data sources, and integrating with third-party tools, making it suited for engineering teams and enterprises that require flexible, self-hosted AI infrastructure. Deployment options include cloud and on-premise environments, giving organizations full control over data residency and model configuration.

LLMStack provides a visual builder for constructing AI workflows without extensive coding, alongside API access for deeper programmatic control. Teams can configure role-based access, manage prompt templates, and monitor usage across projects. The platform supports connections to vector databases, REST APIs, and document stores, enabling retrieval-augmented generation pipelines and context-aware agent behaviors. These capabilities position LLMStack as a practical toolset for product teams building production-grade generative AI features at scale.
