The Full Comparison
FreeCircuitSim is built on CircuitJS1 — the same open-source engine that powers Falstad's simulator — but wrapped with structured learning guides, step-by-step simulations, 360+ described circuit examples, and an AI circuit explainer. It's the only free alternative with a genuine learning platform built around the simulator.
✓ Pros
- No download, no account, no cost
- Real-time animated current flow
- 360+ example circuits
- 7 guided step-by-step simulations
- AI circuit explainer built in
- Works on mobile
- PWA — installable on phone
✗ Cons
- Idealised component models (not manufacturer SPICE)
- Not suited for precision analog design
- No PCB layout tool
LTspice is the gold standard for free SPICE simulation. It uses manufacturer-provided component models so simulation results closely match real-world behaviour. The interface is functional but dated — think 1990s CAD software. There is no browser version and no mobile support. The learning curve is steep, but for serious analog circuit design, nothing free beats it.
✓ Pros
- Accurate SPICE models from Analog Devices
- No subscription or account
- Large user community
- Excellent for filter and amplifier design
✗ Cons
- Download required (Windows / macOS only)
- Steep learning curve
- No animated current flow
- No browser or mobile version
- Complex setup for non-standard components
EasyEDA combines schematic capture, SPICE simulation, and PCB layout in a single browser-based tool. It integrates directly with JLCPCB for low-cost PCB fabrication, making the complete circuit-to-board workflow accessible for students. Requires account registration. The SPICE simulation is more capable than FreeCircuitSim but less visual — no animated current flow.
✓ Pros
- Free, browser-based
- Schematic + simulation + PCB in one tool
- Direct JLCPCB integration
- Large component library
✗ Cons
- Account required
- No animated simulation
- Less beginner-friendly than FreeCircuitSim
- Slower to start compared to no-account tools
FreeCircuitSim is built on the same CircuitJS1 engine as Falstad.com. The core simulation is identical. The difference is the learning resources wrapped around it — Falstad has a minimal interface with no guides, no step-by-step simulations, and poor mobile UX. If you just want the raw simulator, both work. If you want to actually learn electronics, FreeCircuitSim has the content layer.
✓ Pros
- No account, no download
- Same core simulation as FreeCircuitSim
- Established site
✗ Cons
- No learning guides
- Poor mobile UX
- Dated interface
- No step-by-step guided simulations
Tinkercad Circuits is explicitly designed for beginners and classroom use, with a very visual drag-and-drop interface. It includes Arduino simulation with code editing, making it ideal for digital/microcontroller projects. The analog circuit simulation is limited compared to CircuitJS1-based simulators.
✓ Pros
- Very beginner-friendly
- Arduino + code simulation
- Free, browser-based
✗ Cons
- Account required
- Limited analog component support
- Less capable for electronics coursework beyond introductory level
