breve: simulations you can tinker with
A simulation workbench for editing JavaScript rules, changing parameters, and comparing model runs.
- For
- People exploring agent-based and rule-driven simulations
- Worth noticing
- The page lists flocks, ant colonies, epidemics, markets, and walking creatures, and says rules can be edited during a running simulation.
Field notes
The page frames each model as a short JavaScript script paired with a small JSON file, with behavior represented as an editable function. It describes parameter sweeps, mid-run forks, side-by-side comparisons, and interchangeable agent decision systems—from hand-written rules to small neural networks, keyboard input, or a language model. The homepage names flocks, ant colonies, epidemics, markets, and walking creatures as model subjects; the extract does not independently verify the workbench's full feature set.
