# seatunnel vs dify

seatunnel and dify share 8 technologies: tablestore, MySQL, Elasticsearch, SQLite, Vite, Sentry, Tailwind CSS, and echarts. seatunnel is written in Java and dify in Python.

- [apache/seatunnel](https://seerepo.com/r/apache/seatunnel): SeaTunnel is a multimodal, high-performance, distributed, massive data integration tool.
- [langgenius/dify](https://seerepo.com/r/langgenius/dify): Build Agentic workflows, RAG pipelines, with rich AI model and tool support on one collaborative workspace. Deploy on cloud, VPC, or self-hosted, so teams move from prototype to production without rebuilding the stack.

- 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.
