cheetahR vs Prowler
A side-by-side editorial comparison of cheetahR and Prowler — release velocity, themes, recent moves, and the top alternatives to consider.
cheetahR vs Prowler: at a glance
What is cheetahR?
A canvas grid wrapper aiming at the row counts where R's HTML table widgets stop being usable.
cheetahR wraps the Cheetah Grid JavaScript library as an R htmlwidget, positioned by its authors as an alternative to reactable for large datasets. The Shiny surface is now substantial: proxy functions, numeric and date column formatters, sorting, search, column groups, inline and menu cell editors, and a get_grid_data() helper that returns live grid contents as a reactive data frame. The most recent release adds an autocomplete column that suggests values from a list while still accepting free text.
What is Prowler?
Prowler's assistant decides what to do with findings; the patches keep the scanner honest
Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

◆ Current state
cheetahR wraps the Cheetah Grid JavaScript library as an R htmlwidget, positioned by its authors as an alternative to reactable for large datasets. The Shiny surface is now substantial: proxy functions, numeric and date column formatters, sorting, search, column groups, inline and menu cell editors, and a get_grid_data() helper that returns live grid contents as a reactive data frame. The most recent release adds an autocomplete column that suggests values from a list while still accepting free text.
◆ Where it's heading
The arc moves from rendering to editing. Early releases added the read-side affordances a table needs, sorting, search and column grouping, while the last two have been about the grid as an input: proxy functions, cell editors, a typeahead column, and a way to read the edited state back into Shiny. The releases are sparse, roughly three in fourteen months, so this is steady rather than fast work, and the fix in 0.4.0 for renderCheetah() stacking duplicate grids suggests the Shiny integration is still being shaken out under real reactive use.
◆ Prediction
The editing thread points at more column action types and validation on committed values, since an autocomplete that accepts arbitrary text leaves the checking to the app. The performance claim that motivates the package is asserted rather than measured anywhere in these entries.

Prowler's assistant decides what to do with findings; the patches keep the scanner honest
◆ Current state
Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.
◆ Where it's heading
Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.
◆ Prediction
Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.
