    Hi HN,

    I built IndexFlow-core, an open-source search engine indexing infrastructure written in Rust.

    The project started from problems I encountered while building content-heavy websites. I found that making a website available online does not mean search engines can reliably discover and understand it.

    IndexFlow focuses on the technical layer between websites and search engines:

    - Sitemap management

    - SEO quality gates

    - URL discovery

    - Indexing workflows

    - Multi-site scheduling

    - Quota-aware request handling

    The goal is to provide a self-hostable infrastructure layer for developers who care about search engine visibility.
