SVG renderer benchmark

novasvg against resvg, lunasvg, cairosvg, thorvg, nanosvg. Each of the 60 samples is rendered at its own aspect ratio, fit within 320×320px, and timed as the median of 5 runs.

At a glance

Chromium (ground truth) is the reference every other engine is checked against, not a competitor. Its render time includes full browser page-navigation overhead (one shared instance for the whole corpus, one render each, no median-of-N), so it is left out of the charts. RMSE is the root mean squared error against the ground-truth render, at the same pixel dimensions, over all 4 RGBA channels on the 0-255 scale. Squaring before the square root weights a handful of badly wrong pixels (a missing filter, a wrong fill, a shifted shape) far more than the routine anti-aliasing noise along every edge, so low single digits is essentially imperceptible and anything in the tens or higher usually means something structural differs.

Accuracy

Mean RMSE against the Chromium render. Lower is closer.

novasvg15.4
resvg19.2
lunasvg30.9
cairosvg46.0
nanosvg48.3
thorvg76.4

Speed

Average render time per sample. Lower is faster.

thorvg0.64 ms
lunasvg1.85 ms
nanosvg2.16 ms
novasvg2.28 ms
resvg3.38 ms
cairosvg42.92 ms

These charts and the table below are drawn from render_benchmark.json, which sits next to this page.

nanosvg is included as a lightweight baseline, not a fair fight with the other 5. It is a minimal path and gradient rasterizer with no CSS, no filters and no text layout, so its FAILs and blank renders on filter or text heavy samples below are expected scope, not bugs.

Rendered output

Same size (that sample's own aspect ratio, fit within 320×320px) from every engine, side by side, so visual differences (missing text, wrong fills, unapplied filters, ...) are easy to spot. Click any render to zoom in.

Built entirely by benchmarks/CMakeLists.txt (cmake --build build --target novasvg_benchmark) from novasvg's own data/ sample corpus. novasvg, resvg, lunasvg, thorvg and nanosvg are each driven directly through their own C/C++ API in one process (native/*_native_bench.cpp), with no CLI, no per-render subprocess and no Python bindings. cairosvg is the one exception (it has no native library of its own to link against) and runs through its Python binding instead. Chromium (ground truth) is driven through Playwright. Every render is a plain PNG under renders/ next to this page and the numbers are in render_benchmark.json; keep the three together, no server or network is needed to view them, apart from the web fonts, which fall back to system fonts offline.
