I've never seen anything that could even remotely give us what we wanted. We ultimately decided to roll our own devops management platform in-house which was 100% focused on our specific needs. We are now on generation 4 of this system. We just rewrote our principal devops management interface using Blazor w/ Bootstrap4. The capabilities of the management system relative to each environment are fairly absolute - Build/Deploy/Tracing/Configuration/Reporting/etc. is all baked in. We can go from merging a PR in GitHub to a client system being updated with a fresh build of master in exactly 5 button clicks with our new system.
The central service behind the UI is a pure .NET Core solution which is responsible for executing the actual builds. The entire process is self-contained within the codebase itself. Very powerful the contract enforcement you get when the application you are building and tracking is part of the same type system as the application building and tracking it.
I'm curious what a Jenkins + Octopus system is missing that your system provides. Most companies would have a hard time justifying the expense to build a bespoke system just for devops.
Jenkins/octo, as tools, have their place but are just parts of the tooling you need when things go business critical or when teams scale up.
Most companies that run business critical services would be spending wisely putting effort down in building or customizing dev tooling and automations.
