SEOToolSuite

Open source SEO tools for everyone, covering keyword research, competitive research and backlink research, powered by DataForSEO and presented as an alternative to Ahrefs and SEMrush. Users pay only for the DataForSEO usage they consume, with unrestricted access to the data, caching support and a clean, responsive interface built with Next.js and TypeScript. Some free tools need no API at all. API credentials are stored locally in the browser through LocalStorage and are not sent to any server. A cloud version is updated automatically, while the local version follows documented steps, and prerequisites, a credit calculator, a changelog and a Discord server are listed. The whole codebase is released under the MIT license. It is aimed at marketers and developers who want data on keywords, competitors and links without a fixed monthly seat.
