It's similar to Dokku but has a nice web UI, makes it easier to deploy Docker/Compose solutions and auto LetsEncrypt functionality is built-in by design (not as a separate plugin).
I've also built a GitHub Actions workflow to trigger off a deploy to apps hosted on it (basic cURL command but works well). https://github.com/benbristow/dokploy-deploy-action
And put together some pre-configured Compose files you can deploy for various apps. https://github.com/benbristow/dokploy-compose-templates
