q2 vs quarto-r: at a glance
What is q2?
Ten releases in six days, methodically porting Quarto's surface into a Rust binary.
q2 is the Quarto team's Rust reimplementation of Quarto, shipping as a statically linked single binary with signed release archives and a bundled Quarto Hub MCP server. It is explicitly marked experimental and not production-ready, and it is moving fast — ten releases between 7 and 13 August. The release notes are raw commit logs rather than curated summaries, and reading them shows a consistent programme: work items are investigated, design decisions recorded, tests written red, then implemented in numbered phases, with 'Q1 parity' as the recurring benchmark against the existing Quarto.
What is quarto-r?
The R side of Quarto stopped being a render wrapper and became a project interface
The quarto R package gives R users programmatic access to the Quarto CLI, and its 1.4 release is where that access stopped being a thin call to quarto render. Project creation, extension installation, template use, environment diagnostics and a vignette engine all arrived together, and 1.5.0 followed by changing how output paths are communicated to the CLI — through Quarto metadata rather than a command-line flag.

◆ Current state
q2 is the Quarto team's Rust reimplementation of Quarto, shipping as a statically linked single binary with signed release archives and a bundled Quarto Hub MCP server. It is explicitly marked experimental and not production-ready, and it is moving fast — ten releases between 7 and 13 August. The release notes are raw commit logs rather than curated summaries, and reading them shows a consistent programme: work items are investigated, design decisions recorded, tests written red, then implemented in numbered phases, with 'Q1 parity' as the recurring benchmark against the existing Quarto.
◆ Where it's heading
The project is working through the original Quarto's feature surface item by item — project profiles, environment files, shortcodes in metadata, listings, callouts, crossrefs, TOC handling, aliases — while building infrastructure the original lacks, notably a numbered diagnostic catalogue (Q-2-47, Q-14-4 and so on) with a lint that requires a documentation page for every error code. Version 0.18.0's Lua filter support is the load-bearing one, since Quarto's extension ecosystem is written in Lua. Distribution choices point at the same goal: musl-static Linux builds, minisign signatures, no glibc requirement.
◆ Prediction
Expect the parity grind to continue at this cadence, with the remaining high-value Q1 features and diagnostic coverage as the visible queue. The commit logs also show npx distribution planned for the MCP server, which is the nearest thing to a stated roadmap item in these entries.

The R side of Quarto stopped being a render wrapper and became a project interface
◆ Current state
The quarto R package gives R users programmatic access to the Quarto CLI, and its 1.4 release is where that access stopped being a thin call to quarto render. Project creation, extension installation, template use, environment diagnostics and a vignette engine all arrived together, and 1.5.0 followed by changing how output paths are communicated to the CLI — through Quarto metadata rather than a command-line flag.
◆ Where it's heading
The package's job is to stay a faithful surface over a CLI it does not control, and the releases show what that costs. Version numbers track the Quarto release they target, tests are adapted around upstream regressions, and behaviour is reworked when the CLI changes — quarto_use_template() now errors clearly in non-empty directories because interactive prompting was never suitable for programmatic use. The 1.5.1 release exists entirely so CRAN checks pass on machines where Quarto is not installed at all.
◆ Prediction
Expect the next release to track the next Quarto CLI version, with the open question in the feed being how --no-prompt behaviour settles upstream for template use. Feature work here follows the CLI rather than leading it.
