Wokwi review
A browser-based embedded simulator with virtual WiFi, debugging, and CI workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Wokwi is an online simulator for prototyping embedded and IoT projects without physical components. It suits learners, makers, and embedded teams that want to work with simulated boards, sensors, displays, and circuit parts in a browser. Supported projects include Arduino, MicroPython, CircuitPython, Rust, and custom firmware, with board support spanning Arduino, ESP32, STM32, and Raspberry Pi Pico families. Simulated hardware makes it possible to explore firmware behavior before moving to physical components, while custom chip models can be added through the Chips API.
Simulation depth is the main draw. ESP32 projects can use virtual WiFi with internet connectivity, and the interactive debugger offers stepping, variable inspection, and breakpoints for supported boards. A virtual logic analyzer captures and analyzes digital signals. Developers can also run simulations through the VS Code extension, automate firmware simulation tests in CI, and connect workflows with GitHub Actions or GitLab CI. That breadth fits projects where firmware behavior, signals, and network interactions need to be explored together; it may be more than necessary for someone seeking only a basic circuit sketching tool.
According to the vendor’s pricing page, Community is free and includes unlimited simulations, unlimited public projects, and virtual WiFi. Hobby is €5.60 per month billed annually, with 100 monthly fast build minutes, unlisted projects, custom libraries, and a private IoT Gateway. Hobby+ is €8.10 per month billed annually and raises the allowance to 500 fast build minutes, adding Wokwi for VS Code and custom WiFi access points. Wokwi Pro is €20 per seat per month billed annually, with 1,000 fast build minutes, 2,000 CI minutes, an offline VS Code plug-in, and team billing and invoices. Choose Wokwi for firmware simulation and testing workflows; those needing private projects or higher build and CI allowances should compare the paid tiers, while Community projects are public.
Wokwi pros and cons
- Where it wins
- Simulates Arduino, ESP32, STM32, and Raspberry Pi Pico projects
- Debugging, logic analysis, and virtual WiFi support firmware work
- GitHub Actions, GitLab CI, and VS Code integrations extend workflows
- Where it doesn't
- The Community plan makes projects public; unlisted projects require a paid plan
- Fast build and CI minutes are capped on paid plans
- Support channels are community and documentation
