    Project mention: Ubuntu to Make Firefox Snap Default in 21.10 | | 2021-09-17

    Snap is best for server apps. When I release new version of Wekan Open Source kanban , it's very soon updated to all servers around the world. That is great for getting Node.js etc security updates installed fast, making all servers safe. Wekan has automatic database migrations etc for upgrading database structure. Update happens fast, only minimal downtime and then server is running newest Wekan. It has worked great for many years.

    I have not found anything else that would install updates automatically fast like Snap.

    And Canonical paying all that huge server infrastructure for snap updates, build servers, bandwidth, etc.

    And Microsoft paying for all the repo hosting, bandwidth, etc at GitHub.

    And others like Linux Foundation/CNCF, IBM, MacStadium etc providing development and build servers.

    It's all standing shoulders of huge amount of giants. I could not afford all that server infra myself.

    Wekan has Snap, Docker, Source and Sandstorm versions. I'm trying to figure out how to add more packaging formats, and have current packaging formats for more CPU architectures.
