Sidekick is a productivity tool for modern distributed teams. It is designed to reduce onboarding time and provide a dedicated browser for work where all work applications are accessible in one place without having to worry about passwords, credentials, and security.
I think normally, in my day-to-day, I have to navigate multiple screens or reach max GUI sessions fast, a multi-tab, or a way not to lose or manage multiple views. This would help me, as a dev/tester, navigate through processes faster.
If you are a professional agency that requires access to a ton of Saas applications like email, accounting, CRM, websites, etc, then this browser (Sidekick) application is the ticket for you. If you like a ton of features for free, this is not for you. I feel It is breaking my bank account. :(
SAP Enterprise Portal has a very similar feature set to other systems, but the interface is simple and the cost is reasonable. We had quotes provided from Salesforce and other providers, but they did not meet out budgetary requirements or offer features that were different enough to warrant the extra cost. SAP fit the bill for us.
When comparing these two, Sidekick was way easier to use and configure. I got confused immediately when trying to set up workspaces in VIVALDI. Sidekick reminded me of ClickUp and was set up within the hour.
