UpgradeSEO — free, open-source SEO tools you self-host

Keyword research, rank tracking, backlinks, site audit and AI visibility. No subscription, no seat pricing, and no paid data API required.

Try the live demo · sign in with Google, no card, nothing to install.

UpgradeSEO is a self-hosted alternative to Semrush and Ahrefs. It runs on data sources that cost nothing per call, so there is no meter and nothing to bill: Google Search Console and Google Analytics for your own site, Google Autocomplete for keyword ideas, Bing Webmaster and OpenPageRank for volume and authority, Common Crawl for competitor pages.

Bring your own free keys and the bill is zero. That is the whole point, and it is the one thing this fork changes about the project it came from: the upstream needs a paid DataForSEO key to answer a keyword query, and this does not.

All-in-one SEO tool for you and your AI agent.

Connect any MCP client — Claude Code, Claude Desktop, Codex — and it can run keyword research, SERP checks, domain lookups, backlinks and site audits mid conversation. Pre-built skills ship with the repo, and you can write your own.

What it does

Numbers no free source can supply are shown as "no data", never as zero. A dash here means nobody measured it, not that the answer is nothing.

Self-Hosting

UpgradeSEO supports two self-hosting paths:

• Simple: Docker for personal use on your own machine (recommended for getting started). See docs/SELF_HOSTING_DOCKER.md.

• Advanced: Cloudflare for internet-facing self-hosting across multiple devices or with your team (works on the free plan). See docs/SELF_HOSTING_CLOUDFLARE.md.

Costs

UpgradeSEO itself is free: bring your own free-tier keys (Search Console, Bing Webmaster, OpenPageRank, an ads API for volume) and pay nothing per call. What each source provides and refuses to fake is documented in docs/DATA_SOURCES.md.
