OpenSEO
The open source Ahrefs alternative
OpenSEO is an open-source SEO tool that offers keyword research, competitor research, backlinks, and site audits, starting at $10/month instead of the $100-plus monthly subscription of tools like Ahrefs, and it integrates with MCP so that AI agents can use the data for SEO strategy and content writing.
- Problem signal
- Existing SEO tools are expensive (e.g., $100+/month for Ahrefs) and without good data, AI agents give generic advice. OpenSEO addresses this by providing an affordable, open-source alternative with similar functionality.
- Indie angle
- As an open-source project, indie developers can fork, extend, or build niche services on top of OpenSEO, capitalizing on the growing demand for affordable SEO data and AI-driven content strategies.
