# WrenAI vs langflow

WrenAI and langflow share 8 technologies: pyarrow, Rich, cryptography, pyjwt, LangChain, Pydantic, loguru, and boto3. WrenAI is written in Rust and langflow in Python.

- [Canner/WrenAI](https://seerepo.com/r/Canner/WrenAI): GenBI (Generative BI) for AI agents, an open-source, governed text-to-SQL through an open context layer that turns natural-language questions into trusted dashboards, charts, and SQL across 20+ data sources, such as BigQuery, Snowflake, PostgreSQL, ClickHouse, Amazon Redshift, Databricks and more.
- [langflow-ai/langflow](https://seerepo.com/r/langflow-ai/langflow): Langflow is a powerful tool for building and deploying AI-powered agents and workflows.

| Tests | 155 test files. 46.8% 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.
