# PentestGPT vs langflow

PentestGPT and langflow share 6 technologies: OpenAI, Google, Rich, MCP, Pydantic, and loguru. Both are written in Python.

- [GreyDGL/PentestGPT](https://seerepo.com/r/GreyDGL/PentestGPT): Automated Penetration Testing Agentic Framework Powered by Large Language Models
- [langflow-ai/langflow](https://seerepo.com/r/langflow-ai/langflow): Langflow is a powerful tool for building and deploying AI-powered agents and workflows.

| Activity | Last push July 14, 2026, 244 commits, 16,308 stars | Last push November 4, 2026, 17,600 commits, 156,316 stars |
| Tests | 39 test files. 37.5% of its code files have a test that imports them | 3,083 test files. 35.1% of its code files have a test that imports them |

- 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.
