Ohmeris and Wokwi
Wokwi is a browser microcontroller simulator that supports many chip families, with IDE and CI support. Ohmeris is a full electronics workbench: schematic, analog simulation, instruments and a PCB you can manufacture.
Wokwi facts checked 2026-10-24 from the linked public sources. Tell us if something has changed.
Where Wokwi is better
- A free Community option
- Far more microcontrollers, including ESP32, STM32 and RP2350
- IDE extensions, GDB and CI runs for firmware developers
- A larger catalogue of display and sensor parts
Where Ohmeris is different
- Real analog simulation (AC, DC sweep, operating point, transient)
- Scope, multimeters and generator, not only a logic analyser
- A schematic with ERC and a manufacturable PCB
- Benchmate AI with a clear list of every change
Side by side
| Area | Wokwi | Ohmeris |
|---|---|---|
| Price | A free Community option; paid plans are priced in EUR, with Pro shown at about EUR 20 per seat a month when billed annually. [pricing] | Basic $9, Pro $19 or Premier $49 a month after a 7-day trial. |
| Microcontrollers | Many: AVR, ESP32 (Xtensa and RISC-V), STM32 and RP2040/RP2350. [supported hardware] | AVR, PIC16 and a supported RP2040 path. No ESP32 or STM32 yet. |
| Analog simulation | Described by Wokwi as very basic, with no analysis modes. [resistor docs] | ngspice: transient, AC (Bode), DC sweep and operating point. |
| Instruments | A logic analyser; no oscilloscope, multimeter or signal generator. [logic analyser] | Oscilloscope, multimeters, signal generator, logic analyser and I²C/SPI/UART decoders. |
| Schematic and PCB | Wiring diagram; no schematic sheet, ERC or PCB layout. [docs] | Schematic with ERC, 2- or 4-layer PCB with DRC, Gerber/ODB++/KiCad export. |
| Developer tools | VS Code and JetBrains extensions, GDB, CI runs, an experimental MCP server. [CI] | Browser only; no IDE extension or CI runner. |
| Parts catalogue | A large catalogue of displays and sensors. [supported hardware] | Common hobby displays (LCD, OLED, TFT, MAX7219) and live-adjustable sensors. |
| AI | No built-in AI assistant. [docs] | Benchmate drafts and edits schematics; every edit lists what changed and what it kept. |
Which one should you pick?
Pick Wokwi to test firmware on many chips, especially ESP32 or STM32, from your IDE or CI. Pick Ohmeris when the circuit around the chip matters: analog parts, instruments, and a board you can send to a fab.
