Benchmarks
Lightweight replay, measured.
Rejourney publishes SDK size and web analytics benchmark data so teams can understand capture overhead before rolling it into production.
Tiny Footprint.
Extreme Impact.
3.9X smaller package size vs posthog-js. 3.0X smaller median client upload across Next.js, SvelteKit, and Nuxt.
3.9X
smaller gzip payload

Performance Comparison
Bundlephobia package size
Bundlephobia package size metric. Inner segment represents minified + gzipped; total bar is minified.
Web benchmark graphs
Next.js, SvelteKit, and Nuxt examples from 18 live Chromium runs. Lower bars represent better performance.
Median Client Upload Size
Total JavaScript payload compiled/uploaded. Lower is better.
CPU Execution Time
Time spent executing initial tracking scripts. Lower is better.
