We just now launched Slackmin v3 having multi-domain support. With this release, Slackmin can be integrated with Slack apps from different domains. Please let us know how this can prove helpful by giving real world use cases. Also let us know if you find any bugs.
Apart from this you can now use Slackmin outside of express framework. We have tested it with fastify and koa, with snippets added to the example folder.
