# langflow vs inspector

langflow and inspector share 8 technologies: Vite, React, MCP, ace-builds, react-ace, react-icons, react-markdown, and remark-gfm. langflow is written in Python and inspector in TypeScript.

- [langflow-ai/langflow](https://seerepo.com/r/langflow-ai/langflow): Langflow is a powerful tool for building and deploying AI-powered agents and workflows.
- [modelcontextprotocol/inspector](https://seerepo.com/r/modelcontextprotocol/inspector): Deterministic testing tools for MCP servers

| Activity | Last push November 12, 2026, 17,668 commits, 156,550 stars | Last push November 12, 2026, 3,407 commits, 11,283 stars |
| Tests | 3,123 test files. 35.4% of its code files have a test that imports them | 717 test files. 88.9% 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.
