CBTF vs lintr
A side-by-side editorial comparison of CBTF and lintr — release velocity, themes, recent moves, and the top alternatives to consider.
CBTF vs lintr: at a glance
What is CBTF?
A fuzzer for R packages that grew from one argument at a time to parallel runs across whole namespaces.
CBTF throws deliberately problematic inputs at exported functions and reports which ones error, warn, or survive. It now covers 85 input classes, fuzzes multiple named arguments per call, runs in parallel with a per-function timeout, and reports results as a classed object with print, summary, length, and whitelist methods for pruning false positives. Output control has been refined repeatedly — the latest release adds grouping by input or by function and a summary-only mode.
What is lintr?
lintr makes the native pipe the default rule and clears out a decade of deprecations
lintr is the static analysis standard for R packages, and its 3.3.0 release does two things at once: it changes pipe_consistency_linter() to require the native pipe, following the Tidyverse Style Guide, and it completes a long deprecation program — six linters fully deprecated, several arguments defunct, and a batch of functions removed outright. The 3.1.x line before it was accuracy work and a maintainer handoff to Michael Chirico.

CBTF
0.0INFRA · APIS
A fuzzer for R packages that grew from one argument at a time to parallel runs across whole namespaces.
◆ Current state
CBTF throws deliberately problematic inputs at exported functions and reports which ones error, warn, or survive. It now covers 85 input classes, fuzzes multiple named arguments per call, runs in parallel with a per-function timeout, and reports results as a classed object with print, summary, length, and whitelist methods for pruning false positives. Output control has been refined repeatedly — the latest release adds grouping by input or by function and a summary-only mode.
◆ Where it's heading
The package has moved from a script-shaped tool to a test-suite component. The single-argument, sequential fuzz() of the early releases could not finish a large namespace or survive a function that simply hangs; the mirai rewrite fixed both, and multi-argument support widened what a run can actually reach. Nearly everything since has gone into making results triageable rather than merely produced: whitelisting, result classes, grouping, and terminal output that fits real function signatures. Note that the 0.1.0 through 0.3.0 entries carry backfilled timestamps recorded in reverse order within under a minute, so their published dates do not reflect release order.
◆ Prediction
The steady expansion of the input catalogue from 70 to 85 with a new time class suggests more input classes are the cheapest next win; the reporting surface is now detailed enough that machine-readable output for CI would be the natural follow-on.

lintr makes the native pipe the default rule and clears out a decade of deprecations
◆ Current state
lintr is the static analysis standard for R packages, and its 3.3.0 release does two things at once: it changes pipe_consistency_linter() to require the native pipe, following the Tidyverse Style Guide, and it completes a long deprecation program — six linters fully deprecated, several arguments defunct, and a batch of functions removed outright. The 3.1.x line before it was accuracy work and a maintainer handoff to Michael Chirico.
◆ Where it's heading
The package has been consolidating: overlapping linters renamed and merged, configuration validated up front, and an experimental R-script config offered as a possible replacement for the DCF format. Alongside that, a sustained campaign against false positives and false negatives in individual linters, which is where most contributor effort goes.
◆ Prediction
Expect the six warning-deprecated linters to be removed in the next release as announced, and continued movement on the R-script configuration format if feedback supports it.
