Ask HN: What file comparison tool are you using?

I am looking for a file comparison tool with the following features:

- Store multiple sessions per folder

- Store sessions to independent files

- Store session to database (MongoDB, Redis, etc.)

- Multiple hashing algorithms

- Command-line interface

- UI (web or native)

- Multiplatform

- Open-source, ideally simple Python script like drive-py disk comparison tool: https://github.com/web3cryptowallet/drive-py
