Wrote a quick post about where @rari.build's streaming is at now. TTFB is 1ms vs Next.js at 12ms. First content, last byte, and throughput all still tie 🏁

rari's Streaming TTFB is Now 11x Faster Than Next.js. First Content Still Ties.
I ran the /stream bench after official Fizz and an immediate HTML shell flush. The result: 1ms TTFB versus Next.js at 12ms, with first content and throughput still tied.

rari 0.15 is out: the alignment release. The runtime now speaks React's Flight (RSC + actions) and Fizz (HTML/SSR) on Rust + V8, instead of an "RSC-shaped" stack.

rari 0.15: React Flight and Fizz on Rust + V8
rari 0.15 is the alignment release: official React Flight for RSC and server actions, Fizz for HTML SSR and streaming, hosted on Rust with embedded V8. Experimental use cache ships as a follow-on.

Huge thank you to @namespacelabs.com for sponsoring @rari.build as part of their OSS program. Can't overstate how much we're going to benefit from faster GitHub Actions runners

I wrote a technical deep dive on getting @rari.build's throughput to 67x that of Next.js with response caching in Rust, while letting V8 stay idle. The blog post runs on rari itself, with @shiki.style, MDX and Mermaid charts.

Building rari with rari: Dogfooding to 67x Faster Performance
I built rari.build using rari itself. The result: 0.12ms server-side processing, sub-500MB memory, and a server that handled the Hacker News front page without scaling up.

GitHub Sponsors is live for rari — React Server Components on a Rust runtime. 46.5x faster than Next.js. 74K req/sec. Sub-ms latency. 53% smaller bundles. Survived HN front page at ~400MB memory. I want to go full-time on this. Help me prove open source doesn't need a corporate budget to win.

POV: You told developers they had to choose between performance and @react.dev. We said no. 0ms Total Blocking Time. On mobile Slow 4G. With React Server Components.
Lighthouse mobile performance metrics on Slow 4G network (Moto G Power): First Contentful Paint 1.7s, Largest Contentful Paint 1.7s, Total Blocking Time 0ms, Cumulative Layout Shift 0, Speed Index 1.7s. Test captured January 19, 2026 using Lighthouse 13.0.1 with Slow 4G throttling on emulated Moto G Power device.
