Can I use extensions with a self-hosted server?
Extensions are 100% compatible with a self-hosted server. Self-hosting the Standard Notes/Standard File backend server has no impact on this, and there are no unique steps to follow. If you’d like to take advantage of the entire range of productivity-enhancing extensions powered by Standard Notes Extended, feel free to sign up for Extended as usual, and follow the steps from there.
Can I self-host my own extensions?
Unlike our core applications and server, extensions which we have developed ourselves are public-source, but not open-source. Extensions are our main revenue source and how we support development of Standard Notes, and protecting their development is an important step in ensuring longevity. You're always free to develop your own extensions and distribute them at your discretion.
