Relinka is built by Krafts, Inc., a small software studio in Tokyo. We make practical tools for people who run websites — and Relinka is the one we needed ourselves.
Who makes Relinka
Krafts, Inc. is an independent software studio based in Setagaya, Tokyo, led by founder and CEO Ryosuke Kanai. We build focused, honest products rather than sprawling suites — tools that do one job well, respect your data, and don’t lock you in.
Why we built it
Internal linking is one of the highest-leverage, most-ignored parts of on-page SEO, and most of the tools for it are black boxes: they change your content in bulk, can’t explain why, and give you no way to undo. We wanted the opposite — a tool that shows you how your posts connect, suggests links with a plain-English reason and an anchor taken from your own writing, and lets you approve or revert every change in one click. It runs entirely on your own server: no account, no API key, nothing leaves your site.
Relinka is free and open source on WordPress.org. An optional Pro add-on funds continued development.
