Use the build your team already ships.
Run ELF, BIN, and HEX artifacts produced by Zephyr, Rust
no_std, ESP-IDF, or your existing embedded toolchain.
Find the failure before your customer does.
Run the firmware you already build against virtual hardware. Reproduce failures, inspect what happened, and turn every scenario into a repeatable test.

Fault state Used by engineers at
Simulator86 gives embedded teams a programmable environment to develop firmware, reproduce system failures, and validate every release at scale.
From production firmware to synchronized systems.
Keep your existing toolchain, model the complete device, and scale the same deterministic workload across Simulator86 Cloud.
Run every controller in sync.
Connect multiple MCUs inside one environment and observe buses, radio, interrupts, and cross-device timing from the same run.
Turn one scenario into continuous coverage.
Execute deterministic simulations in parallel without maintaining physical benches or a fleet of custom runners.
One simulation environment, across your entire workflow.
Build a system once. Explore it in the IDE, automate it through the SDK, and give engineering agents access through MCP without recreating the project or its scenarios.
SDK
Run the shared project from CI, regression suites, and internal engineering tools. Parallelize scenarios and query results programmatically.
Explore the SDK →MCP
Give coding agents the same system context to run firmware, inspect state, and investigate failures.
Connect MCP →IDE
Open the shared project visually to change hardware, control runtime inputs, and inspect the failing run.
Open the IDE →Before an evaluation.
What engineering teams usually need to establish first.
What is Simulator86?
Simulator86 is a programmable simulation environment for developing, testing, and validating embedded systems before relying on physical hardware.
Can Simulator86 run our real firmware?
Yes. Simulator86 runs compiled firmware inside a virtual hardware environment, allowing teams to test the software they intend to ship.
Does Simulator86 support our framework and libraries?
Yes. Simulator86 is framework- and library-agnostic: if your firmware runs on the real supported chip, it runs on Simulator86.
What can embedded teams use Simulator86 for?
Teams use Simulator86 to develop firmware, reproduce difficult failures, automate testing, and validate system behavior at scale.
Which devices and systems can Simulator86 support?
Simulator86 supports a growing range of embedded architectures, devices, and connected systems. We evaluate each target system to confirm the right simulation coverage.
How does Simulator86 fit into an engineering workflow?
Teams can use Simulator86 interactively, integrate it into automated workflows, or connect it to AI engineering tools through the IDE, SDK, and MCP.
How do we evaluate Simulator86 for our product?
Start with a technical evaluation. We’ll review your firmware, target system, and engineering goals to determine how Simulator86 can support your team.
Bring us one firmware build and the failure your team cannot reproduce.
We’ll scope the virtual system, run the scenario, and show your team the evidence Simulator86 can preserve and replay.
