Short, focused walkthroughs
One task each, start to finish. Every tutorial targets something flowRS does today — you can follow along in the editor without installing anything.
A lesson with a film plays it. The films were recorded on the IDE as it was in late August 2026, and each page says so. The written walkthrough on every page is current, and is the whole lesson where there is no film.
Your first graph, running in the browser
Open the editor, wire a source, a transform and an indicator, and watch values move — no install, no toolchain.
2 minDesign a filter and see its response
Build an IIR filter chain and see what it leaves of a signal's spectrum. The filter designs are checked against SciPy's in flowRS's tests.
1 minTurn existing Rust into a syntax tree, and back
Paste real Rust. The visual syntax tree round-trips it. The signal graph emits Rust one way and is not parsed back.
WrittenCompose and validate an instrument program
Describe a measurement, let the constraint engine reject the impossible, and compile it to SCPI.
1 minFrom graph to firmware
Lower a graph of embedded nodes to a no_std Embassy or RTIC app, and check the RTIC build against the page's own run on a simulated STM32F4.
1 minReal parallelism inside a browser tab
Why flowRS is cross-origin isolated, and what that buys you.
