cheetahR vs q2
A side-by-side editorial comparison of cheetahR and q2 — release velocity, themes, recent moves, and the top alternatives to consider.
cheetahR vs q2: 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 q2?
Two surfaces the original Quarto never had: llms.txt output and a live-share preview.
q2 is the Quarto team's Rust reimplementation, shipping as a statically linked single binary with signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence has held at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. Until v0.22.0 the programme read as pure parity work against the existing Quarto — investigate, record design decisions, write tests red, implement in numbered phases. That release is the first to ship capability the original toolchain does not have.

◆ 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.
q2
7.5INFRA · APIS
Two surfaces the original Quarto never had: llms.txt output and a live-share preview.
◆ Current state
q2 is the Quarto team's Rust reimplementation, shipping as a statically linked single binary with signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence has held at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. Until v0.22.0 the programme read as pure parity work against the existing Quarto — investigate, record design decisions, write tests red, implement in numbered phases. That release is the first to ship capability the original toolchain does not have.
◆ Where it's heading
The parity grind continues underneath — toc-location, add_html_dependency versioning, execute-visibility across both engines — but two strands now point past it. website.llms-txt makes a rendered site emit a machine-readable representation of itself: an llms.txt index, per-page .md companions, and a concatenated llms-full.txt, dogfooded on q2's own docs. The second is a long-running preview branch (PR #464, merged here) that turns q2 preview into a live-share editor with joinable guest sessions over an n0 relay and ephemeral, read-only-by-default boots. A reimplementation that only reaches parity has no argument for itself; these two give it one.
◆ Prediction
Expect the llms-txt and live-share strands to keep absorbing releases now that both have landed end-to-end, with the remaining Q1 parity items filling the gaps. The commit logs still name npx distribution for the standalone MCP bundle as the one explicitly planned item.
