About GNU Octave and BlockWerk

In their own words, as submitted to SaaSHub.

GNU Octave
BlockWerk

No description of GNU Octave yet.

BlockWerk is a browser-based block diagram simulator for control systems and dynamic system modelling. You build a model on a drag-and-drop canvas and a Rust engine compiled to WebAssembly solves it in your browser, using fixed-step RK4, adaptive RK45 (Dormand-Prince) and TR-BDF2 for stiff...

Features and specs

What each product offers, as listed by its team.

GNU Octave 5 features
BlockWerk 7 features
  • Free and Open Source
    GNU Octave is completely free to use and distribute. Its source code is available for anyone to inspect, modify, and enhance, providing transparency and community-driven improvements.
  • MATLAB Compatibility
    Octave aims to be mostly compatible with MATLAB, meaning that many scripts and functions written for MATLAB can run in Octave with little or no modification.
  • Extensive Documentation
    Octave has comprehensive documentation, tutorials, and a vast array of user-contributed content, easing the learning curve for new users.
  • Flexible Integration
    Octave can interface with various programming languages such as C, C++, Fortran, and Python, making it versatile for different types of projects and workflows.
  • Powerful Plotting Capabilities
    Octave includes features for generating high-quality plots and visualizations, which are essential for data analysis and presentation.

Possible disadvantages

  • Performance
    In some cases, Octave may be slower than MATLAB, especially for highly optimized or proprietary algorithms that MATLAB handles more efficiently.
  • GUI and Toolboxes
    While Octave offers a graphical user interface, it is not as polished as MATLAB's. Additionally, the range and quality of toolboxes available in Octave can be more limited compared to MATLAB's extensive and well-supported toolboxes.
  • Community Support
    Although there is a supportive community around Octave, the user base and available support resources are smaller compared to MATLAB's extensive network of forums, user groups, and customer support.
  • Learning Curve for Advanced Features
    While basic operations are straightforward, mastering advanced features and customizations in Octave can require a deeper understanding of its architecture and available functions.
  • Less Industry Adoption
    MATLAB is widely used in industry for research, engineering, and analytics. Octave, being an open-source alternative, lacks the same level of commercial adoption and institutional support, which can be a drawback in professional settings.
  • Runs in the browser
    No install and no account. Projects stay in the browser.
  • Solvers
    RK4, adaptive RK45 (Dormand-Prince) and TR-BDF2 for stiff systems.
  • Engine
    Rust compiled to WebAssembly, running in a Web Worker.
  • Analysis
    FFT, Bode and Nyquist plots, step-response metrics.
  • AI agents
    Remote MCP server and a scripting API for LLMs.
  • Code export
    C++ (Arduino), Python and Rust from a diagram.
  • Sharing
    Diagrams travel as compressed links, nothing is uploaded.

Questions & Answers

As answered by people managing GNU Octave and BlockWerk.

What makes your product unique?

BlockWerk's answer:

A full block-diagram solver in a browser tab.

  • A Rust engine compiled to WebAssembly runs RK4, adaptive RK45 and TR-BDF2 for stiff systems
  • No install and no account
  • A remote MCP server lets an AI assistant build, run and analyse a model for you

Why should a person choose your product over its competitors?

BlockWerk's answer:

Free, fast to start and open to AI assistants.

  • Nothing to install or license
  • Your projects stay in your browser and are shared as links instead of uploads
  • An AI assistant can drive the same canvas you are looking at

How would you describe the primary audience of your product?

BlockWerk's answer:

People who need to model and explain dynamic systems quickly.

  • Control and systems engineers who want a fast model without installing desktop software
  • Students learning control theory and dynamic systems
  • Teams who need to show a simulation to colleagues or customers through a single link

Which are the primary technologies used for building your product?

BlockWerk's answer:

  • Solver engine: Rust compiled to WebAssembly
  • Interface: React and TypeScript
  • Performance: Web Workers and SharedArrayBuffer for streaming results to the scopes
  • AI access: the Model Context Protocol (MCP) and a scripting API

What's the story behind your product?

BlockWerk's answer:

It started as a hobby project to make problems visible.

BlockWerk began as a way to draw block diagrams, so that colleagues in sales could see a problem instead of reading about it. The truth rarely fits in a table. The temperature a material can be used up to, for example, also depends on its history and on its own mass.

  • A block diagram makes those dependencies visible and testable
  • Along the way we started letting AI design the diagrams, and that experiment grew into the MCP server
  • Today you can test or visualise an idea quickly, on your own or with an AI assistant working on the same canvas
