What you give up either way
- Signed prebuilt installers and automatic updater for paid binaries
- Official commercial email support and priority support
- Built-in licensed team features like SSO/user provisioning out-of-the-box
- Paid roadmap influence/priority feature requests
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Yaak, and it does not prove anyone has run it for a month. How we decide.
