randomwalk vs simlandr
A side-by-side editorial comparison of randomwalk and simlandr — release velocity, themes, recent moves, and the top alternatives to consider.
randomwalk vs simlandr: at a glance
What is randomwalk?
randomwalk spent every release getting an R simulation to run in the browser, not on a server.
A random walk and fractal-growth simulation package whose entire visible history is about its browser deployment. Six releases in four weeks moved a Shinylive dashboard from a blank black page to a working app — WebAssembly mounted from GitHub releases, CORS resolved by same-origin serving, missing plotting dependencies installed in-browser, then an async version using crew workers with its own debug log. A correctness fix followed, adding termination-position validation so simulations stop producing isolated pixels, and the most recent release publishes the package itself as a webR binary repository.
What is simlandr?
Potential landscape tooling settling onto standard R generics after two rounds of renaming.
simlandr builds potential landscape plots from simulations of dynamic systems, with barrier-height calculations and batch simulation grids. Its three substantive releases are all consolidation: parameters renamed, functions renamed, defaults removed. By 0.3.0 the bespoke accessors had been replaced by ggplot2's autolayer() and base summary(), and the package carried print, summary, and plot methods for its own classes.

◆ Current state
A random walk and fractal-growth simulation package whose entire visible history is about its browser deployment. Six releases in four weeks moved a Shinylive dashboard from a blank black page to a working app — WebAssembly mounted from GitHub releases, CORS resolved by same-origin serving, missing plotting dependencies installed in-browser, then an async version using crew workers with its own debug log. A correctness fix followed, adding termination-position validation so simulations stop producing isolated pixels, and the most recent release publishes the package itself as a webR binary repository.
◆ Where it's heading
The package is being built as a browser artifact first and an R package second: the readme, the vignettes and the release notes all point at a hosted dashboard rather than at library(). The last release completes that by making the compiled WebAssembly build installable by anyone via webr::install(), which turns the deployment work into something reusable outside this project. Version numbers are unreliable here — v0.2.0 was published two weeks after v1.0.2 — so read the dates, not the tags.
◆ Prediction
With the webR repository published, the next work most likely moves back to the simulation itself, though the entries give no direct evidence of planned features.

◆ Current state
simlandr builds potential landscape plots from simulations of dynamic systems, with barrier-height calculations and batch simulation grids.

By 0.3.0 the bespoke accessors had been replaced by ggplot2's autolayer() and base summary(), and the package carried print, summary, and plot methods for its own classes.
◆ Where it's heading
Every release trades a package-specific name for a conventional one - var and par became arg and ele, get_geom() became an autolayer() method, get_barrier_height() became a summary() method, hash_big.matrix became hash_big_matrix. The one methodological change, an adjusted minimal energy path algorithm, arrived inside a release otherwise full of renames. Removing default values for barrier calculation because they were often unsuitable reads as the maintainer deciding the defaults were doing harm.
◆ Prediction
The feed stops at 0.3.0 in late 2022, mid-consolidation; these entries give no indication of what followed, if anything did.

Frequently asked questions
What is the difference between randomwalk and simlandr?
They serve adjacent needs but don't currently overlap on shipped themes. randomwalk and simlandr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Is randomwalk better than simlandr?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. randomwalk and simlandr are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
