Category: Instrumentation & System DesignVerified for 2025

Top Recommended Replacements

Python (PyVISA / PyMeasure)

FREE

Best Professional Alternative

Why we like it

100% free; massive library support for almost every instrument (VISA, Serial, GPIB); easy integration with modern AI and data science stacks; text-based logic is easier to track in Git.

Keep in mind

Lacks the native 'Visual GUI' drag-and-drop builder; requires manual threading management for high-speed parallel tasks.

MyOpenLab

FREE

Best for Education & Simple Logic

Why we like it

Graphical interface that mimics LabVIEW's look and feel; excellent for Arduino and Raspberry Pi control; Java-based and cross-platform; zero cost.

Keep in mind

Not suitable for low-latency or high-performance FPGA tasks; smaller component library compared to the NI ecosystem.

GNU Radio

FREE

Best for Signal Processing & RF

Why we like it

Graphical block-diagram interface similar to LabVIEW; optimized for high-speed signal processing and Software Defined Radio (SDR); world-class community for RF engineering.

Keep in mind

Focused strictly on signal processing; lacks the 'General Purpose' instrumentation drivers (like DMMs or PLCs) found in LabVIEW.

SweepMe!

FREE

Best for Rapid Lab Automation

Why we like it

Combines a graphical sequencer with Python flexibility; 'Device Class' system allows for zero-code instrument setup; ideal for materials science and physics labs.

Keep in mind

Proprietary modular pricing (you pay per instrument driver); less flexible for building complex custom UIs compared to LabVIEW.

LabJack (LJLog/LJStream)

FREE

Best for Low-Cost DAQ

Why we like it

If you use LabJack hardware, their software is incredibly stable and free; great 'Dashboard' style interfaces; excellent Python and C++ APIs.

Keep in mind

Locked to LabJack hardware; not a general-purpose programming environment.

InstrumentStudio (NI)

FREE

Best for 'No-Code' NI Users

Why we like it

Modern, interactive multi-instrument environment; allows you to configure NI hardware without writing a single line of G-code; very high performance.

Keep in mind

Limited to NI hardware; 'Professional' features (like automation) are expensive.

DASYLab

Best for Industrial Data Logging

Why we like it

The 'Easy LabVIEW'; purely graphical with no 'wiring'—you just connect modules; exceptional for high-speed data acquisition and logging.

Keep in mind

Limited mathematical flexibility; proprietary and Windows-only.

Node-RED

FREE

Best for IoT & Web Dashboards

Why we like it

Browser-based flow programming; exceptional at connecting hardware to web APIs; perfect for your Best Free Alternatives news/community portal metrics.

Keep in mind

Not designed for high-speed DAQ (>1kHz); lacks specialized scientific analysis toolboxes.

Scilab Xcos

FREE

Best for Control Systems

Why we like it

Visual block diagram editor; excellent for simulating physical systems before deployment; completely free.

Keep in mind

Interfacing with real-time hardware is significantly more difficult than in LabVIEW.

Lark Suite (with Lark Base)

FREE

Best for Data Management

Why we like it

Can be used as a front-end to log test data via Webhooks; excellent for collaborative lab notes and reporting; handles billions of rows in 2026.

Keep in mind

Not a programming tool; strictly for the 'management' of test data after it's acquired.
