rvest vs workflows
A side-by-side editorial comparison of rvest and workflows — release velocity, themes, recent moves, and the top alternatives to consider.
rvest vs workflows: at a glance
What is rvest?
rvest grew a real browser, turning a static scraper into a dynamic one.
rvest is the tidyverse's HTML scraping package. The 1.0.0 line rebuilt table parsing to mimic how browsers actually read tables, and 1.0.4 added read_html_live(), which drives a headless browser so JavaScript-rendered pages can be scraped at all. 1.0.5 is consolidation on that newer path.
What is workflows?
The tidymodels pipeline grew a third stage, and it happens after the model runs.
workflows bundles a preprocessor and a model into one object that tidymodels can fit, tune and extract from. Version 1.3.0 added a post stage backed by the tailor package, wired through every generic a workflow supports — augment, tidy, tunable, tune_args, required_pkgs and parameter extraction. Version 1.2.0 added sparse data support so fit() and predict() accept dgCMatrix and sparse tibbles. Earlier releases in view are boundary tightening: erroring on unknown model modes, on trained recipes, and on silently ignored formula offsets.

rvest
0.0ANALYTICS
rvest grew a real browser, turning a static scraper into a dynamic one.
◆ Current state
rvest is the tidyverse's HTML scraping package. The 1.0.0 line rebuilt table parsing to mimic how browsers actually read tables, and 1.0.4 added read_html_live(), which drives a headless browser so JavaScript-rendered pages can be scraped at all. 1.0.5 is consolidation on that newer path.
◆ Where it's heading
The package has split into two modes: fast static parsing for ordinary documents, and a live browser session for client-rendered ones. Recent effort concentrates on hardening the live path, where page navigation and interaction bugs surface that never existed in static parsing.
◆ Prediction
Expect further fixes and documentation around read_html_live() as more scraping targets move rendering to the client.

0.0ANALYTICS
The tidymodels pipeline grew a third stage, and it happens after the model runs.
◆ Current state
workflows bundles a preprocessor and a model into one object that tidymodels can fit, tune and extract from. Version 1.3.0 added a post stage backed by the tailor package, wired through every generic a workflow supports — augment, tidy, tunable, tune_args, required_pkgs and parameter extraction. Version 1.2.0 added sparse data support so fit() and predict() accept dgCMatrix and sparse tibbles. Earlier releases in view are boundary tightening: erroring on unknown model modes, on trained recipes, and on silently ignored formula offsets.
◆ Where it's heading
The object is filling out into a complete pipeline description rather than a preprocessing-plus-model pair. Postprocessing is the structural addition — calibration and threshold selection were previously done by hand after prediction, outside anything tidymodels could tune or record — and the fact that it arrived integrated with tunable() and tune_args() rather than as a standalone step is the point. The rest of the arc is the steady tidymodels habit of converting silent guesses into errors.
◆ Prediction
Expect tailor postprocessors to spread through tune and workflowsets next, since the parameter and tuning generics were wired up first, and expect sparse support to extend to more engines after lightgbm.
