Are you investing several man-hours to build your microservices today?

Coupler offers an alternative, simpler method to build microservices using a low-code / no-code approach. It accelerates your microservices initiative by upto 40%. Coupler speeds up implementation through a flow-based visual integration tool that rapidly and seamlessly integrates external data sources and applications. It offers high scalability and extensibility through containerization, and literally eliminates the need for coding for integration use-cases. You can now manage and optimize distributed microservices and applications from a central control panel.

Modules of Coupler

Integration flow management

Create, manage, deploy, and version the integration flows as a visual diagram without code. Flows can be imported and used in multiple environments without the need for an update. This multi-environment approach allows for quick and easy configurations and deployments. You can manage various environment variables from a single place. For example:

  • Use different backend hosts for a service based on environment – If the flow is invoking a service, use different backend hosts in the test environment and the production environment without having to update the flow.
  • Use a different access-key while invoking a service based on environment – Have different access-keys/API keys to be used in different environments.
Coupler core

Based on the incoming request, the lightweight coupler core intelligently determines the right flow to invoke. It uses deployed flows as the blueprints to resolve any mappings done inside the node’s input within the flow. In case of a node failure, the core gracefully handles the error so that the whole system remains resilient to any error that can occur at runtime.

When creating flows, indicate the type of action to be taken for a given error in a node. This ensures real-time error handling to keep your system protected against runtime errors.

User management

Provide relevant access to your users and enable seamless coordination across all configured integration flows, versions, products, and environments.

How Coupler works

Infographic about the workings of Coupler
Improved developer experience


The low-code / no-code approach to building Microservices provides a simplified experience to developers. It allows them to swiftly develop Microservice-based applications across a range of platforms, including the web, mobile, IoT, wearables, and more.
Failsafe integration changes


Integration flow management with flow versioning allows you to tweak a flow while it’s still running. You can also test each change multiple times without any effect on the original integration flow.
Easy-to-use dashboard


A user-friendly, visual dashboard gives a clear picture for each integration flow – for yourself, for your colleagues, or for any other individual who wants to know more about a specific flow than just the name.


Achieve secure and seamless interoperability via protocol conversion. Coupler also offers REST/SOAP, SSL & TLS, and IoT protocol support.
Increased system observability


Observe how they use your product through visibility on how Microservices are used through log analytics and transaction monitoring. Develop and quickly deploy new features to modify your solution as per their needs.
