YourSim Studio — one-pager
A visual, browser-based studio for modelling service/queue/network systems — build it on a canvas, run experiments, optimize the design, watch it animate, and ask an AI companion for help. Free to use.
👉 yoursim.plantagoai.com · powered by the open-source YourSim Engine
Who it's for
Analysts, consultants, operations and capacity planners, educators, and students who need to answer "how will this system behave, and what's the cheapest design that meets my target?" — without writing code.
What you can do
- Build — drag-and-drop the 12 block types (sources, queues, resources, delays, pools, routing, batching, assembly…) onto a themed canvas; group and collapse/replicate sub-systems (
×N) to model big topologies cleanly. Domain templates included: airport, hospital ER, bank, factory, restaurant, M/M/1, M/M/c, and a global corporate network (100k clients across branches). - Experiment — run N replications and get a KPI dashboard: waits, utilization, throughput, percentiles, histograms, and over-time charts with 95% confidence intervals.
- Optimize — set a budget and service targets; the Cross-Entropy optimizer finds the cheapest staffing/capacity, with a live convergence + search-distribution view, then applies it to your model.
- Present — a skinned "watch mode" animates entities flowing through the system; export a video (MP4) for stakeholders.
- Ask AI — a built-in companion (managed, no API key needed) helps build, explain, tune, and optimize models in plain English.
- Story & export — a plain-English narrative on every view (AI-drafted, editable) and one-click export to JSON / PDF / MP4.
How it's built
A React + MUI single-page app running the YourSim Engine in a Web Worker (so the UI stays smooth). Models are yours — saved locally and optionally to your account; the AI companion runs through a managed backend that stores no model content.
