Ohmeris and Flux
Flux is a well-funded browser PCB tool with a broad AI agent. Ohmeris focuses on flat monthly plans, a bench with instruments and firmware, and files you can take anywhere.
Flux facts checked 2026-10-24 from the linked public sources. Tell us if something has changed.
Where Flux is better
- A broader AI agent that also places, routes and prepares fab files
- EM simulation for high-speed boards
- Live distributor stock inside the editor
- More export formats, including IPC-2581C and STEP
- A large community and integrations such as an MCP server
Where Ohmeris is different
- One flat monthly price with no AI credits
- Firmware and instruments on the circuit you drew
- KiCad export and an open JSON copy of every project
- Every AI edit shows exactly what it changed
Side by side
| Area | Flux | Ohmeris |
|---|---|---|
| Price | Explore $50/month (40 AI credits), Build $100 (120), Pro $250 (400, with a $250 hold), Teams $500/month for 5 seats; extra credits $2 each. No free plan is listed. [pricing] | Basic $9 (40 AI designs a month), Pro $19 (100), Premier $49 (280); flat, and a design is one circuit request, repairs included. Top-ups (coming soon): 50 designs for $9. |
| AI usage | Metered in AI credits (ACUs), with on-demand charges beyond the monthly allowance. [ACUs] | A monthly number of AI designs (40 / 100 / 280) with a daily limit, plus 50-design top-ups that never expire (coming soon). One request is one design, even when the AI repairs its own attempt. |
| AI scope | Described as an “AI hardware engineer for end to end design” on every plan. [pricing] | Drafts and edits schematics. Every edit lists what changed, what was kept and what was not checked. |
| Simulation | SPICE simulation from a chat prompt, and EM simulation of routed boards. [blog] | Transient, AC (Bode), DC sweep and operating point. No EM simulation. |
| Firmware on the circuit | Not documented in the Flux docs index. [docs index] | AVR, PIC16 and a supported RP2040 path run against your schematic. |
| Instruments | Not documented in the Flux docs index. [docs index] | Oscilloscope, multimeters, logic analyser and I²C/SPI/UART decoders. |
| PCB | Layer stackup editor, design-rule checks, AI-assisted layout. [stackup] | 2 or 4 layers, push-and-shove routing, DRC, pours, length matching. |
| Import | Migration guides for KiCad, Eagle, Altium and EasyEDA projects. [KiCad guide] | KiCad PCB, EasyEDA Standard and Eagle schematics. |
| Export | Gerber, BOM, pick-and-place, IPC-2581C, EDIF and IPC-D-356 netlists, STEP/STL/COLLADA, Flux project files. KiCad is not among the listed formats. [portability] | KiCad PCB, Gerber, ODB++, IPC-356, pick-and-place, SPICE netlist, open JSON. |
| Parts and stock | Live stock and pricing from distributors inside the editor. [supply chain] | Part search with sample prices for now; live distributor pricing is being connected. |
| Teamwork | Sharing with permission levels, and version history. [sharing] | Real-time editing, shared projects, saved revisions you can replay exactly. |
| Trial | 7-day free trial on individual plans; the selected plan begins after 7 days. [pricing] | 7-day trial without a card. Exports start with a paid plan. |
Which one should you pick?
Pick Flux if you want an AI agent to take a board from idea to fab files and you are comfortable with credit-based pricing. Pick Ohmeris if you want to learn and test circuits on a bench, keep your files portable, and pay one predictable price.
