What do you like best?
UX - Hands down the best UX, I've had on any CI/CD tool. Status and progress are very clear, so there's never a question about what's happening and you don't have to read through a wall of text before you're able to identify issues. Setting up your workflow aka "pipeline" is a very easy process, which is crucial because it's the crux of the whole system.
UI - Modern and sleek, clearly subjective, however, the tool itself is not a cookie cutter design and there was a lot of thought put into the aesthetic, which definitely separates it from other tools within the same space.
Flexibility - One of the issues with other GUI driven CI/CD tools we've experienced is it's lack of flexibility, however, Buddy doesn't have those same limitations. Comes with pretty much everything you expect and/or want from any CI/CD tool. Automation, notifications, cloning, Rsync (clutch), variables (seemingly simple, but also clutch), SSH, 3rd party connections, "CRON" jobs, etc. the list goes on. All done without being forced to write a single config. file.
Speed - One the fastest, if not the fastest deployment tools we've used.
Sandboxes ... yea ... sandboxes
What do you dislike?
If you're doing the self-hosted "Enterprise" version, updating is not horrible, but it is kinda clunky. There's a way to update through the GUI, however, more often than not, it still forces you to SSH into your server to update a package.
Every now and again, when there's a change, it's not as well documented as it could've been. Without being too long-winded, Buddy 2.0 forced a key change for all projects, w/o detailing that it was a required update. Having to update a lot of projects with new keys was a bear.
Pricing. Now granted, the pricing model is on par with other services, and that's fine., and this just recently (1.x => 2.0) changed. But you previously were able to have a working free version, which is no longer available, which is to the detriment of freelancers. If you were grandfathered in or want to stay with version 1.0, that's all good, but you don't get all the 2.0 goodies.
Support response times, a bit longer, but that's only really due to the fact that we're on opposite sides of the globe, but if you're based in the US, keep that in mind.
What business problems are you solving with the product? What benefits have you realized?
We needed a reliable CI/CD tool, that we could keep under lock-and-key on our own servers, that had all the flexibility of all the other major players in this space. This provides us with unprecedented speed, simplicity, and flexibility that just works, without any real compromise.
