g6R vs q2
A side-by-side editorial comparison of g6R and q2 — release velocity, themes, recent moves, and the top alternatives to consider.
g6R vs q2: at a glance
What is g6R?
An R binding whose releases are mostly the upstream JS graph engine arriving, plus port ergonomics.
g6R wraps AntV's G6 graph engine as an htmlwidget, with Shiny proxy functions for data updates, layout control and mouse position read-back. The current release bundles G6 5.1.1 and ships the widget as a single self-contained bundle, having removed the split chunk. Recent work has concentrated on ports, the connection points nodes expose, with a new label-bottom placement, a larger default radius and a quieter hover state.
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.

g6R
2.5INFRA · APIS
An R binding whose releases are mostly the upstream JS graph engine arriving, plus port ergonomics.
◆ Current state
g6R wraps AntV's G6 graph engine as an htmlwidget, with Shiny proxy functions for data updates, layout control and mouse position read-back. The current release bundles G6 5.1.1 and ships the widget as a single self-contained bundle, having removed the split chunk. Recent work has concentrated on ports, the connection points nodes expose, with a new label-bottom placement, a larger default radius and a quieter hover state.
◆ Where it's heading
Two threads run through the record. One is upstream tracking: the 0.6.5 engine bump alone restored the SVG renderer, fixed a combo-related canvas crash and pulled in new node and edge query APIs, which is a lot of user-visible change that this package did not author. The other is R-side ergonomics, where ports have been reworked in three consecutive releases and 0.5.0 added data validation strict enough that the notes warn existing code may break. Layout behaviour has moved toward explicit control, with recomputation now opt-in via an option and a dedicated proxy function.
◆ Prediction
The port work looks unfinished given three releases in a row on it, so more placement and styling options are the likeliest next step, alongside another engine bump as G6 5.1.x moves. Nothing in these entries indicates a direction beyond keeping pace with upstream.
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.
