For reference, vdiffr shipped 0 meaningful updates in the last 30 days and carries a velocity score of 0.0 out of 10 in 2026. The alternatives below are ranked the same way, so you're comparing real release momentum, not marketing claims.
About vdiffr
vdiffr finished its job in 2021 and has been tracking compilers ever since.
vdiffr generates deterministic SVG snapshots so plot changes show up as test failures. Its recent history is almost entirely toolchain: UCRT Windows compatibility twice, a revert to C++11 to work around a GCC issue, and renaming the internal SVG device so it stops colliding with svglite. The only functional additions in view are snapshot variants in 1.0.8 and a testthat fix so snapshots are no longer auto-deleted when a test errors or skips. The last release was October 2024.
