Rankdelta

Rankdelta is the open-source, agent-native SEO + GEO platform. It combines keyword research, rank tracking, site audits, backlink summaries, and AI-visibility (Share-of-Voice across ChatGPT, Perplexity, Gemini & Google AI Overviews) with an AI Content Writer. A hosted MCP server lets Claude, Cursor, or any AI agent run these tools directly. Self-host it (AGPL) or use the hosted plan from $29/mo.
