About Nirai.app and Solid Edge

In their own words, as submitted to SaaSHub.

Nirai.app
Solid Edge

Nirai is a browser-based system dynamics and stock-and-flow simulator. Unlike traditional tools that show results as line charts, Nirai animates the same model as real water flowing through tanks and pipes — so feedback loops and bottlenecks are something you watch, not decode. Built on a...

Questions & Answers

As answered by people managing Nirai.app and Solid Edge.

What makes your product unique?

Nirai.app's answer

Nirai is the only system dynamics simulator that animates your model as real water flowing through tanks and pipes — instead of plotting results as line charts. This makes feedback loops, bottlenecks, and oscillations immediately visible without decoding numbers. It runs entirely in the browser via a Rust/WASM engine with no install required, exports simulations as MP4 videos, imports XMILE files from Vensim and Stella, and includes an AI tutor that edits your model directly on the canvas using your own API key. Nothing is processed on Nirai's servers

Which are the primary technologies used for building your product?

Nirai.app's answer

Nirai is built with Rust compiled to WebAssembly (WASM) for the simulation engine, using RK4 numerical integration and the fasteval2 formula engine for lookup tables, trigonometric functions, and stochastic expressions. The frontend is Vue 3 with Tailwind CSS, compiled with Vite and pre-rendered as static pages via Vite SSG. The AI assistant integrates with OpenAI, Google Gemini, and OpenRouter via the user's own API key. The app is hosted on Netlify and functions as a Progressive Web App with offline support.

Why should a person choose your product over its competitors?

Nirai.app's answer

Vensim and Stella Architect require desktop installation, cost hundreds of dollars per year, and show results only as line charts. InsightMaker is browser-based but has no animation, no MP4 export, and no AI assistance. Nirai combines all the things competitors lack: runs in the browser for free, animates the simulation visually, exports MP4 for presentations, imports existing XMILE models so you don't start from scratch, and includes an AI tutor that works on your canvas. Pro is a one-time $99 — not a recurring subscription.

How would you describe the primary audience of your product?

Nirai.app's answer

Nirai is built for three groups. Educators and students who teach or learn system dynamics and need a free, browser-based tool that requires no installation and produces shareable, visual results. Analysts and consultants who need to communicate system behaviour to non-technical clients and want to export animated simulations into slides or decks. Engineers and researchers who already use Vensim or Stella and want a faster, browser-native tool that can import their existing XMILE models.

What's the story behind your product?

Nirai.app's answer

Nirai was built by a solo developer who was frustrated that every system dynamics tool — Vensim, Stella, InsightMaker — shows simulation results as line charts you have to read and interpret. The idea was simple: what if the simulation looked like the thing it was modelling? A supply chain model where you can actually watch inventory surge and lag. An epidemic model where you watch people move between compartments. That visual clarity became the core of Nirai. The simulation engine was built in Rust compiled to WebAssembly so it runs at native speed entirely in the browser, with no server round-trips and no install barrier

Who are some of the biggest customers of your product?

Nirai.app's answer

Nirai launched in 2026 and is in its early stage. Current users include system dynamics educators, independent analysts, and engineers exploring browser-based alternatives to Vensim and Stella.
