Our company has acquired 15+ smaller entities that all have different service desk providers (e.g. ServiceNow, Zendesk, Jira, Freshservice), 2 CRMs (HubSpot and Salesforce) and different knowledge base tools etc.

We are trying to centralize support now but don't yet want to do the heavy lift of merging all software as we will likely do 20+ more acquisitions.

Typically, our agents will have several web apps open on their desktop: ticketing, the knowledgebase, Splunk or Dynatrace for some of the customer information, a map and some other etc.

Is there an interface app maker that can put these all in a single interface and can merge the apps and multiple service desks (maybe in iFrames or something)? Ideally, when a new support ticket pops up, it can make an API call in the other open apps to look for the relevant data?

Thanks in advance.
