I mean I created Octane coming from being one of the authors of React from years ago. Octane makes breaking changes compared to React to improve on things that aren’t that important in 2026. For example the synthetic event system - which takes up 13kb of React’s payload and adds overhead over just using the correct DOM events.
TSRX allows for better runtime generated guarantees, especially around loops which generates faster runtime logic from it. We can’t assume too much statically when reading something.map as the method might have different heuristics
It has all the same SSR APIs as React. The Octane website is rendered with Octane and the source is in the GitHub repository if you’re interested to see how it works
We just run a script that runs the benchmarks and updates the chart. It’s rounds numbers too. We’ve been as honest as possible in all the benchmarks - there’s no point in lying about a metric.
