About
Visual drag-and-drop workflow and agent builder for LLM apps.
This AI tool is designed to make the core workflow faster, more structured, and easier to repeat. It combines focused functionality with AI-assisted processing so users can spend less time on manual steps and move from input to useful output more efficiently.
It is useful for professionals, creators, developers, founders, marketers, and teams when the product matches a recurring workflow. The strongest results come from using the tool for a clear job, reviewing important outputs, and connecting it with the systems already used by the team.
Langflow is open-source and free. Managed cloud sandboxes are free, with production hosting billed on usage depending on cloud resources (CPU, RAM, API calls) and database connections. Buyers should also consider platform support, usage limits, integrations, privacy requirements, and the expected volume of work before selecting a plan.
