The Integration Gateway

Ship the feature. Skip the glue.

Your applications, agents, and the teams behind them all reach every service they need through one governed path—running in your infrastructure, not ours.

One governed contractApplications and agents

Enablement

Four ways in. One Engine underneath.

Agents, applications, development teams, and event-driven systems each get an experience shaped for the work they do—while the integration problems every one of them would otherwise solve alone get solved once.

Agent

Physical + Unified operations, without handing over the keys.

Application

Features that span five services, and read like they span one.

Developers & Teams

Integrations become infrastructure, not the tribal knowledge of one team.

Event-Driven Systems

Provider activity becomes a product moment. Retry loop not included.

FUSED ENGINEThe runtime behind every integration.Fast execution, governed access, and operational visibility.

The product boundary

What Fused is—and what it isn’t.

Fused takes over service access and execution. Your team keeps the application logic, the deployment, and the infrastructure the traffic runs through. That line does not move.

Is Fused an iPaaS or workflow builder?

No. There is no canvas, and nothing gets sequenced by dragging boxes onto it. Fused gives your software and your agents a consistent, governed way to call APIs and receive webhooks. What happens next stays your application's business.

Does Fused run in our infrastructure?

It can, and most teams want it to. Deploy Engine in your VPC, Kubernetes cluster, or cloud of choice with a license key, or let Fused provision an isolated one for you. Either way, request payloads, encrypted credentials, connected-user tokens, and webhook delivery state stay with the Engine.

How do products and agents use Fused?

Applications get a generated Capability SDK holding only the services and events that product actually selected. Agents get an MCP Server with two tools: search_docs to find physical and Unified operations, and execute to run one governed operation or a bounded TypeScript sequence.

How does Fused handle webhooks?

Engine verifies the provider signature, normalizes the payload, queues it durably, and delivers it to the applications allowed to receive that event. Nobody has to write the retry loop again.

Can we control which services each team can use?

Yes—that is rather the point. Platform teams decide which services and operations each team, application, and agent can reach. A team can use a credential bucket without being able to read what is inside it.
