Our standard

Open source is the start.
Respect is the test.

We do not recommend a project because its repository exists. Every guide is structured around the questions that determine whether switching is actually worth it.

See our review method
  1. 01
    Privacy

    Does it work without an account? Where does your data live? What telemetry is on?

  2. 02
    Lightweight by design

    Does the tool avoid background services, feature clutter, and unnecessary cloud dependencies?

  3. 03
    Healthy enough to trust

    We look for active maintenance, transparent issues, clear licensing, and a real community.

  4. 04
    An honest verdict

    Every page explains who should switch—and who may be better staying with the commercial tool.
