Doppelio is a connected product validation platform that helps engineering and quality teams test IoT and connected product applications by virtualizing devices, simulating real-world conditions, and automating validation at scale.

How does Doppelio test connected products without physical devices?

Doppelio creates virtual test twins, called Doppels, that replicate the communication patterns, data behavior, state, and workflows of physical devices. Teams can use these virtual devices to test device applications, cloud platforms, APIs, gateways, and end-to-end connected product workflows without waiting for physical hardware.

What types of testing does Doppelio support?

Doppelio supports functional testing, device application testing, regression testing, load and performance testing, network condition testing, scale testing, interoperability testing, and post-release troubleshooting.

Can Doppelio test connected products at scale?

Yes. Doppelio can simulate realistic device-like loads involving thousands or millions of connected devices. This helps teams validate application performance, infrastructure capacity, connection management, throughput, and system behavior before large-scale deployment.

Can Doppelio simulate real-world network conditions?

Yes. Doppelio can simulate conditions such as network latency, limited bandwidth, packet loss, delayed messages, duplicate messages, out-of-order messages, connection failures, and intermittent connectivity. This helps teams validate how connected products behave outside ideal laboratory environments.

What devices and protocols does Doppelio support?

Doppelio can virtualize simple sensors, gateways, mobile devices, connected machines, medical devices, vehicles, meters, industrial equipment, and systems of connected devices. It supports standard protocols such as MQTT, AMQP, HTTP and HTTPS, TCP and UDP, as well as custom and industry-specific protocols such as HL7 and DLMS.

Can Doppelio test both device and cloud applications?

Yes. Doppelio supports validation across the connected product stack, including device and edge applications, gateways, communication layers, cloud services, APIs, data processing systems, mobile applications, and end-to-end workflows.

Does Doppelio integrate with existing test automation and CI/CD tools?

Yes. Doppelio provides APIs that allow teams to integrate virtual devices and test scenarios with existing automation frameworks, test management platforms, and CI/CD pipelines. This enables continuous connected product validation as part of the software delivery process.

Does Doppelio replace physical device testing?

No. Doppelio complements physical testing. Virtual testing allows teams to execute more scenarios, test earlier, automate repetitive validations, and validate at greater scale. Physical devices can then be used strategically for hardware-specific and final-stage validation.

How does Doppelio help accelerate connected product releases?

Doppelio removes delays caused by limited device availability, manual test setup, infrastructure provisioning, and dependence on hardware teams. Development and validation teams can work in parallel, run repeatable scenarios on demand, and identify defects earlier in the product lifecycle.

What is Doppelio Observability?

Doppelio Observability extends connected product assurance into production. It helps teams actively exercise customer workflows, detect failures and unusual behavior, confirm customer impact, and accelerate root cause analysis across the device, network, edge, and cloud.

Which industries use Doppelio?

Doppelio supports connected product validation across industries such as automotive, healthcare, utilities, industrial equipment, smart buildings, logistics, connected elevators, security systems, supply chain, and consumer IoT.

How can I evaluate Doppelio?

You can request a personalized demo. The Doppelio team can demonstrate how devices are virtualized, how real-world test scenarios are created, and how testing can be automated and scaled for your connected product architecture.

Doppelio — The Four Pillars

How It Works

Four pillars. One connected validation platform.

Doppelio virtualizes devices, simulates real-world conditions, automates testing across the lifecycle, and puts agents to work throughout. Explore how each pillar fits together.

Digital Twins

Decouple validation from physical hardware.

Doppelio creates high-fidelity digital twins, called Doppels, of any connected device: sensors, actuators, gateways, Android and iOS devices. Doppels replicate real device behavior, including state transitions, protocol interactions, security characteristics, timing patterns, and fault modes. Teams stop waiting for devices and start validating from day one.

Real-World Scenarios

Reproduce production reality, at unlimited scale.

Once devices are virtualized, Doppelio brings them to life through simulation. Run unlimited scenarios, including normal behavior, fault conditions, edge cases, firmware variants, and network degradation, concurrently across millions of virtual devices. Produce conditions physical lab environments never could.

Full Lifecycle

Automate quality across the entire connected product lifecycle.

Doppelio supports every testing discipline your connected product requires, from the first unit test through post-release monitoring, in a single platform. It integrates directly into your CI/CD pipeline, so validation runs automatically and consistently on every build.

Agent Workflow

Agents do the work, inside the tools you already use.

Each stage of the validation lifecycle is handled by a dedicated agent. The agents do not require a separate interface. They operate inside the coding agents, QA agents, and CI/CD pipelines your engineers already use as their primary environment.
