Firms that build their own platforms build on interop.io
Developers ship apps independently. Platform engineers deploy and govern them in one place. And end users get a streamlined experience where every app works as one.
What is Desktop Interoperability?
Desktop interoperability is the ability for different applications to work together as a single, connected system — sharing context, triggering actions, and supporting end-to-end workflows, for the people who build them, the teams who run them, and the users who depend on them.
Financial firms are managing thousands of applications — legacy systems, vendor tools, and modern platforms that still operate in isolation. Users spend their day switching between them, manually bridging gaps between systems that were never designed to work together.
That costs traders minutes on every action and technologists months on every integration. Add AI to the mix and integration debt becomes an even bigger problem.
interop.io is what firms build their platforms on, so they can ship faster, operate more effectively, introduce AI with governance, and give users one connected experience with the applications they already trust.
Our Products

One Platform Across
Build, Run, and Experience
Every desk is different. The platform underneath isn’t. Build your platform on interop.io and bring the applications you already have into it: web, third-party, legacy desktop, and mainframe. Prove it on one desk, then carry the same investment to the next business unit. Common services exist once, and the pattern is reused instead of rebuilt.
The payoff shows up on both sides: firms report shorter development cycles, and end users spend less time switching screens and re-keying data.
Built for Developers, Platform Engineers, End Users & Their AI
One orchestration layer that your end users won’t even know is there, with AI taking part at every stage under the same controls as the people it works for.
Build
Interop-enable an application once and it works with everything else in the workspace, on the open FDC3 standard. Teams build their own apps, their way, and ship on their own schedule without a central release train.
Run
Govern the whole estate from one place: what is deployed, to whom, how it is used, and what changed when. An auditable control plane replaces the scripts and local configuration a custom build leaves behind, all inside the security and entitlements you already control.
Experience
Every application on the desk works as one. The right data surfaces in the app the user already trusts, one action carries across every linked screen, and owned, vendor, and legacy apps, even mainframe, work side by side instead of each in its own window. In the desktop or the user’s trusted browser, with nothing new to retrain on.

Make Your Applications AI-Ready
Add AI assistants, live business context, and governed tool access to the applications and workflows you already run, without rebuilding them.

Desktop Interoperability: Common Questions
Desktop interoperability lets the applications on a desktop work together as one: sharing context, triggering actions, and supporting end-to-end workflows across web, native, and legacy apps, whoever built them.
Traditional integration connects systems in the background. Desktop interoperability connects them where people work, so applications share context and trigger actions for the user, and platform teams can govern the whole estate from one place rather than one integration at a time.
Firms with strong engineering teams build their own desktops from owned, vendor, and legacy applications. Interoperability is the layer underneath that lets each application be enabled once and reused across every desk, instead of being rewired for each one.
Yes. Legacy, mainframe, and green-screen applications join the same desktop as modern ones, and can be replaced one screen at a time while the old system keeps running underneath.
AI is only as useful as the applications it can see and act in. Interoperability gives AI the context of what the user is doing and governed access to approved actions inside the applications people already use, under the same controls as the people it works for.
It is how we describe the three jobs a platform has to do: engineers build and ship applications independently, platform teams run and govern them from one place, and users and their AI experience them as one connected desktop. interop.io is the one platform underneath all three.
No. Nothing is ripped out. Existing applications are interop-enabled once and keep running; you modernize incrementally and keep building your own applications, your way.
