Open-Source AI SEO & GEO Platform · Rankdelta

FAQ
Is it really free?
Yes — the app is AGPL-3.0 and self-hostable at no cost. You only pay DataForSEO and OpenRouter directly for the data and AI you use, with no markup from us. The managed cloud (rankdelta.ai) is the paid, hosted convenience.
Is this an open-source Ahrefs or Semrush alternative?
It covers the same core jobs — Site Explorer, keyword research, rank tracking, audits — but open source, self-hostable, and AI-native: AI-visibility/GEO tracking is included, not sold as an add-on. Their crawl indexes are bigger; ours is open and honest that traffic numbers are estimates.
What do I need to self-host?
Docker, a Supabase instance (free/open-source via Supabase’s own Docker, or a Supabase project), a DataForSEO account, and an OpenRouter API key. Full steps are in SELF_HOSTING.md.
Does the open edition nag me to upgrade?
No. Self-host has no billing, paywall, credits, trial prompts or upgrade walls — every feature is unlocked. The cloud handles billing; the code you run does not.
How is it different from OpenSEO?
OpenSEO is a great project — MIT-licensed, the most-starred open-source SEO suite, with its own MCP server. Rankdelta differs in four ways. AI visibility runs your own prompts live on ChatGPT, Perplexity and Gemini through OpenRouter, at about $0.004 per prompt per engine; OpenSEO reads DataForSEO’s pre-collected LLM Mentions database ($0.10 per request plus $0.001 per row, ChatGPT and Google AI). It includes an SEO/GEO article writer grounded in live SERP research, with fact-checking, verified citations and no invented statistics. Reports are built from your data — AI visibility, rankings, Search Console and GA4 — for your own sites or white-labelled for clients, with scheduled email and PDF/PowerPoint export, where OpenSEO’s reports are agent-written HTML pages. And the interface, prompts and reports are in English and Italian. Rankdelta is AGPL-3.0, OpenSEO is MIT. Based on public docs and pricing as of September 2026.
What is GEO (Generative Engine Optimization)?
GEO is getting your brand cited by AI assistants like ChatGPT and Perplexity, not just ranked on Google. As people ask AI instead of searching, being the source an AI quotes is the new top of the funnel — and this tracks exactly that.
