The Salesforce Platform is designed for building and deploying scalable cloud applications with managed hardware provisioning and app stacks. Lightning Web Components are used by developers to build reusable UI components.
If you have your own in-house servers or have a cloud server with the freedom to configure any PaaS that you want, then Dokku is for you. So far, I have never run into a scenario where Dokku was not able to fit my needs, after deploying many different types of applications with varying frameworks, languages, and connected services. If you already have a PaaS available, however, Dokku may not be for you.
If you have a large customer base and a large amount of data on each of your customers, it is really strong in creating personalized content that your salespeople can use in their pitch meetings—and then setting up workflows for automated for lifecycle journey creations to automatically go out to customers.
Dokku might overreach on its assumptions about how you want to host your app, using its own VHOSTS plugin by default. This may be a pro or a con depending on what you want.
Proxy port configuration can be somewhat difficult, with Dokku resetting any pre-deployment configuration to "smart" defaults on the first deployment.
It's very good, but it's still living in a little bit in an older design aspect, but I think a lot of it is about to come out, just hasn't quite gotten there yet. Still a little clunky from a you have to know it to know it or you know it to use it. It takes a little bit of training to get into it. It's not quite the, anybody can come in and start using it immediately, type feel.
Dokku is incredibly well documented and also takes advantage of the documentation and community of Heroku, being essentially the same thing, but in the case that you encounter an actual bug or issue, it can take time for a fix to make it into a new version. Since you manage Dokku yourself, there is no support team to call for help.
I am not an administrator so there may very well be outstanding Support and I am just not privy to it. On a user level it's hard to gauge the effectiveness and responsiveness of Support because nearly everything has to go through an administrator
Dokku is essentially the same thing as Heroku, except maintained by you on the platform of your choice. If you have any experience using Heroku, then you will feel right at home using Dokku. Dokku is an entirely free to use PaaS, requiring only that you have a platform to deploy it on, making it far more versatile than Heroku in my opinion.
We were previously using an older version prior to it becoming Salesforce Lightning Platform so we were well adverse on the advantages of using a CRM, to begin with. It made sense to convert to Salesforce Lightning Platform after we were given a free trial of the platform. Certain reps were chosen to experiment with it and from there a decision was made to move forward. We've been customers ever since.
