Takumi

Turn JSX into production-ready images fast.
OG cards, banners, and lightweight animations from one Rust engine for Node.js and WebAssembly.

Docs · Playground

Takumi is inspired by satori, with a stronger focus on portability and performance.

Why teams pick Takumi

• Direct image rendering with no SVG-to-image conversion step.
• One JSX pipeline across runtimes for Node.js, browsers, and edge workers.
• Native performance on Node.js with WebAssembly fallback when portability matters.
• Production-grade text and font support including variable fonts, COLR, WOFF2, and RTL.
• Flexible output targets from WebP, PNG, JPEG, and GIF to raw frames for FFmpeg pipelines.

Performance

Takumi is built for fast image rendering across Node.js and WebAssembly runtimes. See current benchmark runs and templates on Image Bench, including comparisons with next/og.

First render in 30 seconds

npm i @takumi-rs/image-response

import { ImageResponse } from "@takumi-rs/image-response";

export function GET() {
  return new ImageResponse(
    <div tw="w-full h-full flex items-center justify-center bg-white">
      <h1 tw="text-6xl font-bold">Hello from Takumi 👋😁</h1>
    </div>,
    {
      width: 1200,
      height: 630,
      format: "webp",
      emoji: "twemoji",
    },
  );
}
