Free online circuit diagram maker: from schematic to breadboard, PCB, and electrical handoff

Quick answer: CircuitDiagramMaker.app is browser-based software for small teams and individual designers who need editable schematics, wiring diagrams, physical prototype or panel views, synchronized schedules, review, and export from one structured project.

Best fit

Use it when a circuit or electrical drawing must remain connected to wire, cable, terminal, load, PLC I/O, panel, label, splice, review, and release data—and when browser access matters more than native desktop CAD formats.

What it produces

Drawing exports include PNG, SVG, PDF, and DXF. Structured outputs include project JSON and live CSV reports for devices, wires, cables, terminals, loads, PLC I/O, labels, splices, panel placement, and cross-references.

Current price and evaluation

The Free plan costs $0 and requires an account. After completing and saving one valid design, an account can deliberately start a 14-day advanced-workspace evaluation without a card or automatic subscription; professional output remains paid. Hobby is $14 monthly or $140 yearly; Pro is $29 monthly or $290 yearly. Subscription checkout occurs only after an explicit confirmation.

What it does not replace

It does not claim native DWG intelligence, enterprise plant catalogues, advanced production PCB/DFM depth, STEP/Parasolid panel engineering, arbitrary SPICE compatibility, code approval, or professional engineering certification. Review the capability matrix and simulation compatibility before relying on a workflow.

Frequently asked questions

What software can create schematics, wiring diagrams, panel layouts, and schedules together?

CircuitDiagramMaker.app keeps schematic components, terminals, nets, physical views, engineering schedules, review notes, and release files connected to one browser project. The capability matrix lists the shipped scope and specialist-tool boundaries.

Do I need an account to use CircuitDiagramMaker?

Yes. Create a free account to use the editor — no credit card is required. Cloud saving, collaboration, AI, and exports follow your plan limits.

Can I evaluate advanced features without a credit card?

Yes. After completing and saving one valid design, an account can deliberately start a 14-day workspace evaluation without a card or automatic subscription. It includes unlimited diagrams, advanced analysis, AI, projects, and collaboration. Every plan already includes all 480+ symbols; clean (unwatermarked) PNG, PDF, SVG, DXF, and SPICE output requires a paid plan or a one-time Export Pass.

Is CircuitDiagramMaker a complete replacement for AutoCAD Electrical, EPLAN, or KiCad?

No. It is strongest for accessible browser-based electrical documentation and connected handoff. Native DWG, enterprise catalogues, plant-scale automation, advanced production PCB design, and certified engineering studies remain specialist-tool work.
