Comparison
Banana Board vs Wokwi
Banana Board and Wokwi are both browser-based and both aimed at people building with Arduino, ESP32, and similar boards, but they solve different parts of the problem. Wokwi is a mature, well-loved simulator: you wire up a circuit and write the code yourself, then watch it run against a faithful model of the hardware. Banana Board starts from a plain-English description and generates the firmware, wiring, a pin-by-pin table checked against the board's real pin map, and a fab-ready PCB, with an in-browser simulation included.
Banana Board vs Wokwi, feature by feature
| Feature | Banana Board | Wokwi |
|---|---|---|
| Primary input | Plain-English prompt | Manual wiring + code |
| Firmware generation | Yes, generated + compiled | You write it |
| Validates against real pin map | Yes, every connection | Not the focus |
| Electrical rule checks | Power, ground, strapping, ADC | Via simulation behavior |
| In-browser simulation | Yes (Arduino/Uno) | Yes, broad and mature |
| Part / board breadth | 11 boards, core parts | Very wide library |
| PCB layout | Placed + routed, 2-layer | Not supported |
| Gerber / fab export | Yes, Gerber + KiCad | Not supported |
| Flash to hardware | Yes, over USB (Web Serial) | Simulator-based |
| Learning curve | Low, describe and refine | Low to moderate |
| Price | Free tier | Free + paid membership |
Comparison written to be factual and fair. Competitor features change over time, so check Wokwi for the latest.
What Wokwi is great at
- Deep, mature simulation of Arduino, ESP32, Raspberry Pi Pico and many other boards, so you can test logic and timing before touching hardware.
- Very wide library of parts and sensors, including displays, motors, and custom chips you can define yourself.
- Free and open in spirit, with an active community, shared projects, and lots of public examples to learn from.
- Great for teaching and experimentation: you can share a link and someone else can run the exact same circuit in their browser.
- Strong debugging feel because you run real code against a faithful model and watch it behave step by step.
Where Banana Board is stronger
- Prompt-to-circuit: describe what you want in plain English and get firmware, wiring, and a bill of materials without building it by hand first.
- Every connection is checked against the target board's real pin map, so it does not hallucinate pins or silently misuse input-only or strapping pins.
- Electrical-rule checks for power, ground, double-drive, and ADC, plus a power budget, before you commit to hardware.
- Firmware and a placed, routed 2-layer PCB in one place, with fab-ready Gerber and KiCad export.
- Flash to real hardware over USB and simulate in the browser, so the same design goes from idea to board without switching tools.
Which should you use?
Choose Wokwi when
Choose Wokwi when you want to hand-build and deeply simulate a circuit, especially with exotic parts, custom chips, or a board or peripheral outside Banana Board's supported set, and when watching your own code run against a faithful hardware model is the main goal.
Choose Banana Board when
Choose Banana Board when you want to go from a plain-English description to validated wiring, generated firmware, a bill of materials, and a fab-ready PCB quickly, and you care most about connections being checked against real pins rather than hand-assembling and simulating every detail yourself.
Try it freeFrequently asked questions
Is Wokwi free?
Wokwi is free to use in the browser and has a large body of public projects. It also offers a paid membership with additional features. Banana Board has a free tier as well.
Can Banana Board replace Wokwi?
Not entirely. Banana Board includes an in-browser Arduino simulation and adds validation, firmware generation, and PCB output, but Wokwi's simulation is broader and more mature across parts and boards. Many people would use Wokwi for deep simulation and Banana Board for going from a description to a validated, fab-ready design.
Which is better for beginners?
Both are approachable. Wokwi is great for learning by building and running circuits yourself. Banana Board is faster if you would rather describe what you want and get a checked wiring diagram, firmware, and parts list to start from.
Does Wokwi do PCB layout or Gerber export?
Wokwi is focused on simulation, not PCB layout or fabrication output. Banana Board produces a placed and routed 2-layer PCB with Gerber and KiCad export.
Does Banana Board check my wiring against the real board?
Yes. Every connection is validated against the target board's actual pin map, and it runs electrical-rule checks for power, ground, double-drive, and input-only or strapping pins. This is a core difference from a simulator-first workflow.
Build it, do not just look it up
Describe your circuit in one sentence and Banana Board wires it to these exact pins, validates it, and lays out a fab-ready PCB.
