API gateways and integration middleware that route 1B daily events without foreign API dependency, foreign ESB lock-in, or foreign event-mesh exposure.
API gateway, iPaaS, ESB, event mesh, service mesh, message queue, and the sovereign integration middleware that lets institutions integrate at scale. Dewelopers's API, integration & middleware stack is the most-deployed sovereign integration platform in production — 200+ sovereign platforms, 100,000+ APIs, 1B+ daily events, 14 country deployments. The integration layer that the institution runs on, the institution owns.

What This Is
Clear definition of the capability, service, or platform.
API, integration, and middleware are the integrated technology layer that lets institutions connect, orchestrate, and route between systems, services, and partners. The category encompasses API gateway, iPaaS (Integration Platform as a Service), ESB (Enterprise Service Bus), event mesh, service mesh, message queues, B2B integration, and the sovereign integration middleware that ties them all together. These are not commercial integration platforms (MuleSoft, Apigee, Kong, Confluent) — they are sovereign integration middleware deployed on customer infrastructure, with full ownership and control. **Sovereign integration operates under constraints that commercial platforms cannot meet.** Data sovereignty — every API call, every event, every integration payload stays on-shore, under customer control. Operational sovereignty — every API call, every event routing, every integration orchestration stays in the customer's security domain. Cryptographic sovereignty — integration data is encrypted with customer-controlled keys. Dewelopers's API, integration & middleware stack is purpose-built for these constraints — 200+ platforms, 100,000+ APIs, 1B+ daily events. **The strategic question for institutions is not whether to adopt API gateway and middleware — it is which.** Commercial API gateway (Apigee, MuleSoft, Kong) carries vendor lock-in, per-call fees, and data sovereignty exposure. Foreign-vendor ESB (IBM, Oracle) carries vendor lock-in and supply-chain exposure. Open-source middleware (Kong, Apache Kafka, RabbitMQ) requires operational hardening. Dewelopers's sovereign API, integration & middleware stack is the path forward: full source-available code, customer-operated, on-shore deployment, sovereign integration. We do not deliver commercial middleware with a sovereignty skin. We deliver the integrated technology layer that a sovereign institution uses to connect its systems, services, and partners — and we hand over the operations to the customer's own people when the engagement concludes.
What This Is Not
- —A commercial API gateway (Apigee, MuleSoft, Kong) — this is sovereign API gateway, deployed on customer infrastructure, with full ownership.
- —A foreign-vendor ESB (IBM, Oracle) — this is fully sovereign, customer-owned, source-available.
- —An open-source middleware (Kong, Kafka, RabbitMQ) without operational hardening — this is production-grade sovereign middleware with security, performance, and integration.
- —A pilot project or a single-system deployment — this is the integrated middleware layer for institution-scale sovereign operation.
- —An imported foreign product — every component is owned, source-available, and operated by the customer.
Strategic Significance
Why this matters at the strategic level.
API and integration infrastructure operates under a strategic pressure that no commercial middleware vendor can meet. The 2020-2024 API-first boom has made API infrastructure a strategic asset. The 2024-2025 surge in sovereign integration initiatives has made national integration sovereignty a strategic priority. The 2024 EU DORA regulation adds operational resilience requirements. The strategic question for every national institution is whether the next decade of integration modernization is built on sovereign middleware or on foreign SaaS. **Integration is foundational national infrastructure.** If a state's integration layer is foreign-controlled, every system that depends on it is foreign-compromised — citizen services, defence, healthcare, banking, public administration. Dewelopers's sovereign integration stack is engineered for the post-foreign-SaaS threat model: data sovereignty, supply-chain sovereignty, cryptographic sovereignty, and full ownership transfer. **The strategic landscape is shifting.** The 2024-2025 surge in sovereign integration initiatives is accelerating procurement of national-scale sovereign middleware. The 2024 EU DORA regulation adds operational resilience requirements. The 2025-2026 national integration modernization programs are accelerating procurement of sovereign middleware. The strategic question for every national institution is whether the next decade of integration modernization is built on sovereign middleware or on foreign SaaS. **The cost of waiting is integration sovereignty erosion.** Every year on foreign middleware is a year of compounding data sovereignty exposure, accumulating vendor lock-in, and rising per-call fees. The cost is not zero — it is the gradual erosion of the integration sovereignty that defines a sovereign national integration capability. Dewelopers's sovereign API, integration & middleware stack can be deployed in 6-9 months for a pilot system, 18-36 months for a national rollout. The time horizon is shorter than most procurement frameworks assume.

National Deployment
All systems. All integration patterns. Full sovereign rollout. 18-36 months. The national deployment is the integrated middleware layer that the national institution runs on — sovereign, API-first, with full operational handover.
Strategic Partnership
Multi-decade partnership. Continuous modernization. Institutional continuity. 36-60 months initial, with multi-year follow-on. The strategic partnership is the institutional technology backbone of sovereign integration, modernized continuously over decades.
What Clients Ask
Common questions from prospective clients.
How is this different from a commercial API gateway (Apigee, MuleSoft, Kong)?
Commercial API gateway vendors deliver foreign-controlled API infrastructure. The customer sends API calls to a foreign cloud, the foreign vendor processes the API calls, and the customer receives analytics. The API data, the integration data, the analytics are all foreign-controlled. Dewelopers delivers sovereign API gateway — every API call stays on-shore, every operation runs in the customer's security domain. The depth difference is the difference between a foreign-controlled SaaS API gateway and a sovereign API gateway that the customer fully owns.
How is this different from a foreign-vendor ESB (IBM, Oracle)?
Foreign-vendor ESB vendors deliver proprietary, vendor-locked middleware. Dewelopers delivers sovereign ESB with full source-available code, full sovereign ownership transfer, and customer-controlled data. The depth difference is the difference between a vendor-locked ESB and a sovereign ESB that the customer fully owns.
What protocols and standards are supported?
REST, GraphQL, gRPC, gRPC-Web, WebSocket, MQTT, AMQP, STOMP, JMS, Kafka, Pulsar, NATS, RabbitMQ, EDI (X12, EDIFACT, TRADACOMS), S/FTP, AS2, OFTP. OpenAPI 3.x, AsyncAPI 2.x, OData. Customer-controlled, customer-operated, source-available.
What about B2B integration and EDI?
B2B integration — EDI (X12, EDIFACT, TRADACOMS), partner APIs, partner onboarding, B2B gateway. 50,000+ B2B partners in production across 14 country deployments. Customer-controlled, customer-operated, on-shore.
How long does an integration deployment take?
A pilot system (one system, one integration pattern) takes 6-9 months. A national rollout (all systems, all integration patterns) takes 18-36 months. A full strategic partnership (multi-decade, continuous modernization) takes 36-60 months initial with multi-year follow-on. These are real numbers from real deployments across 200+ sovereign platforms — not vendor marketing projections.
Can the integration middleware integrate with existing CRM, ERP, and mainframe systems?
Yes. The integration middleware is designed for interoperability with existing systems — CRM, ERP, mainframe, AS/400, identity, payment, communication. Integration is over standard protocols with cryptographic adapters where required.
What is the warranty and support model?
Dewelopers provides a 5-year operational warranty on the deployed stack, with full source-available code, full sovereign ownership transfer to the customer, and 24/7/365 support via the customer's preferred channel (on-site, sovereign remote, or hybrid). Annual architecture reviews are included. Major version upgrades are supported for 10 years from deployment.
