Langflow is a visual interface for building and orchestrating workflows, allowing users to construct complex systems through a drag-and-drop canvas. It provides tools for managing autonomous agents, configuring memory settings, and integrating custom code-based components. Users can organize their work into projects, track component versions, and group multiple elements into reusable units.
The platform includes an interactive playground for testing workflows, monitoring tool calls, and debugging chat sessions with unique identifiers. Once built, workflows can be executed via RESTful or OpenAI-compatible APIs, embedded into external websites as chat widgets, or exposed as tools through the Model Context Protocol.
Deployment is supported through various methods, including containerized environments, desktop installations, and standard package management. The system incorporates security features such as environment variable management, header injection for credentials, and infrastructure-level isolation for multi-tenant setups.
