This page is designed to help you find out whether BlockWerk is good and if it is the right choice for you.
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 systems.
The block library covers sources, arithmetic and logic, PID controllers, transfer functions, state-space models, lookup tables and analysis blocks such as FFT, Bode and Nyquist. Scopes plot results while the solver is still running.
There is nothing to install and no account to create. Projects stay in your browser and are shared as compressed links instead of uploads. BlockWerk also offers a scripting API and a remote MCP server, so an AI assistant such as Claude, ChatGPT or Cursor can build, run and analyse a model for you. It is free to use.

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.
We have collected here some useful links to help you find out if BlockWerk is good.
Check the traffic stats of BlockWerk on SimilarWeb. The key metrics to look for are: monthly visits, average visit duration, pages per visit, and traffic by country. Moreoever, check the traffic sources. For example "Direct" traffic is a good sign.
Check the "Domain Rating" of BlockWerk on Ahrefs. The domain rating is a measure of the strength of a website's backlink profile on a scale from 0 to 100. It shows the strength of BlockWerk's backlink profile compared to the other websites. In most cases a domain rating of 60+ is considered good and 70+ is considered very good.
Check the "Domain Authority" of BlockWerk on MOZ. A website's domain authority (DA) is a search engine ranking score that predicts how well a website will rank on search engine result pages (SERPs). It is based on a 100-point logarithmic scale, with higher scores corresponding to a greater likelihood of ranking. This is another useful metric to check if a website is good.
