# langflow vs OpenMontage

langflow and OpenMontage share 8 technologies: FastAPI, Google, OpenAI, uvicorn, React, pillow, Pydantic, and jsonschema. Both are written in Python.

- [langflow-ai/langflow](https://seerepo.com/r/langflow-ai/langflow): Langflow is a powerful tool for building and deploying AI-powered agents and workflows.
- [OpenMontageInc/OpenMontage](https://seerepo.com/r/OpenMontageInc/OpenMontage): World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant into a full video production studio.

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
