# langflow vs OpenViking

langflow and OpenViking share 5 technologies: React, Vite, FastAPI, Redis, and OpenAI. 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.
- [volcengine/OpenViking](https://seerepo.com/r/volcengine/OpenViking): Self-evolving Context Database for AI Agents. Unify Agent Memory, Knowledge RAG and Skills.

## What they share and what sets them apart

- In common: React, Vite, FastAPI, Redis, OpenAI
- Only in langflow: Google
- Only in OpenViking: Anthropic

## Side by side

| | langflow | OpenViking |
|---|---|---|
| Size | 1,438,179 lines written, 4,003 code files | 1,109,640 lines written, 1,964 code files |
| Who writes it | 1.5% of its commits signed by AI. With Claude Code, CodeRabbit, GitHub Copilot, Cursor, Codex, and Warp | 8.2% of its commits signed by AI. With Claude Code, Cursor, and Codex |
| Activity | Last push October 29, 2026, 17,563 commits, 156,138 stars | Last push October 31, 2026, 3,051 commits, 41,225 stars |
| Tests | 3,061 test files. 34.4% of its code files have a test that imports them | 1,353 test files. 56.6% 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.
