Best Multisim Alternatives in 2026

Multisim Live shuts down on September 15, 2026. If you've been using it for coursework, teaching, or hobby projects, here's an honest breakdown of every realistic alternative β€” what each one is actually good at, and who should use it.

⚠️ Confirmed shutdown: NI/Digilent has announced Multisim Live reaches End-of-Life September 15, 2026. Monthly subscriptions end August 1, 2026. Export your saved circuits before this date β€” they will not be recoverable after shutdown.

The Full Comparison

FreeCircuitSim Best Free Browser Option
Browser-based Β· Free Β· No account Β· This site
Best for: Students, beginners, anyone who wants to start simulating in under 30 seconds.

FreeCircuitSim is built on CircuitJS1 β€” the same open-source engine that powers Falstad's simulator β€” 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.

βœ“ 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 β€” installable on phone

βœ— Cons

  • Idealised component models (not manufacturer SPICE)
  • Not suited for precision analog design
  • No PCB layout tool

LTspice
Desktop (Windows / macOS) Β· Free Β· Analog Devices
Best for: Engineering students and professionals who need accurate SPICE simulation with real component models.

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 β€” 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.

βœ“ Pros

  • Accurate SPICE models from Analog Devices
  • No subscription or account
  • Large user community
  • Excellent for filter and amplifier design

βœ— 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
Browser-based Β· Free (account required) Β· Integrated PCB design
Best for: Students who want to simulate AND design a PCB for manufacturing in one workflow.

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 β€” no animated current flow.

βœ“ Pros

  • Free, browser-based
  • Schematic + simulation + PCB in one tool
  • Direct JLCPCB integration
  • Large component library

βœ— Cons

  • Account required
  • No animated simulation
  • Less beginner-friendly than FreeCircuitSim
  • Slower to start compared to no-account tools
Falstad Circuit Simulator
Browser-based Β· Free Β· No account
Best for: Visual circuit exploration with no setup.

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 β€” 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.

βœ“ Pros

  • No account, no download
  • Same core simulation as FreeCircuitSim
  • Established site

βœ— Cons

  • No learning guides
  • Poor mobile UX
  • Dated interface
  • No step-by-step guided simulations
Tinkercad Circuits
Browser-based Β· Free Β· Account required Β· Autodesk
Best for: Absolute beginners and middle/high school Arduino projects.

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.

βœ“ Pros

  • Very beginner-friendly
  • Arduino + code simulation
  • Free, browser-based

βœ— Cons

  • Account required
  • Limited analog component support
  • Less capable for electronics coursework beyond introductory level

Frequently Asked Questions

When exactly is Multisim Live shutting down?
Multisim Live reaches End-of-Life on September 15, 2026. Monthly subscriptions end August 1, 2026. All saved circuits should be exported before this date as they will be inaccessible after shutdown. The desktop Multisim (NI Circuit Design Suite) is not being discontinued.
Can I import my Multisim circuits into FreeCircuitSim?
Not directly β€” Multisim uses a proprietary file format that is not compatible with CircuitJS1. You will need to recreate circuits manually. The 360+ example circuits in FreeCircuitSim cover most common circuit types used in coursework, so most students can find a close starting point to modify rather than starting from scratch.
Is FreeCircuitSim accurate enough for university coursework?
For most undergraduate coursework β€” DC analysis, AC circuits, filter design, transistor basics, op-amp configurations, digital logic, and power electronics β€” yes. The simulation engine uses accurate models for all standard components. For precision analog design requiring exact manufacturer SPICE models, LTspice is more appropriate.
