# crewAI vs adk-python

crewAI and adk-python share 7 technologies: FastAPI, aiosqlite, SQLite, cryptography, Pydantic, opentelemetry-api, and OpenTelemetry. Both are written in Python.

- [crewAIInc/crewAI](https://seerepo.com/r/crewAIInc/crewAI): Framework for orchestrating role-playing, autonomous AI agents. By fostering collaborative intelligence, CrewAI empowers agents to work together seamlessly, tackling complex tasks.
- [google/adk-python](https://seerepo.com/r/google/adk-python): An open-source, code-first Python toolkit for building, evaluating, and deploying sophisticated AI agents with flexibility and control.

## What they share and what sets them apart

- In common: FastAPI, aiosqlite, SQLite, cryptography, Pydantic, opentelemetry-api, OpenTelemetry

| Activity | Last push November 5, 2026, 3,039 commits, 60,522 stars | Last push November 5, 2026, 5,111 commits, 22,107 stars |
| Tests | 511 test files. 11.2% of its code files have a test that imports them | 864 test files. 74.4% 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.
