Why RSSHub Needs a Complete Rewrite: Lessons from Six Years of Open‑Source Maintenance
After six years of rapid growth, the open‑source RSSHub project faces hidden maintenance costs, outdated architecture, and scalability challenges, prompting its author to overhaul the codebase with modern technologies like TypeScript, ESM, and a new framework to ensure future sustainability.
RSSHub is an open‑source, easy‑to‑extend RSS generator that can create feeds for a wide variety of content. It has grown rapidly thanks to community contributions, now boasting nearly 30k stars, over 900 contributors, more than 300 million requests per month, and steady sponsorship.
The project, maintained for six years, is now on the brink of collapse.
Behind the impressive metrics lie hidden costs: several years of high maintenance effort, over $1,000 per month in server fees, and daily repetitive tasks that strain the maintainers.
The original codebase, built six years ago with a “Next Generation” Node.js stack, has become outdated.
Modern technologies such as JSX, TypeScript, and serverless cannot be applied, and the architecture is fragmented—routing information is scattered across multiple files, requiring changes in several places for a single route update, which leads to high workload and errors.
Given these constraints, the author decided to rewrite the core using a modern framework and a redesigned architecture.
Planned technology updates
koa → Hono
JavaScript → TypeScript
CommonJS → ESM
art-template → JSX
Jest → Vitest
