Is it right for you?

Business owners, freelancers and agencies who want keyword research, backlinks, rank tracking and site audits for much less than the big SEO tools, especially if they use an AI agent such as Claude or Codex.

Replaces some features, but not everything.

Look elsewhere if you need:

  • You want SEO data without usage costs: research uses paid credits on the hosted version, or your own paid DataForSEO account when you run it yourself.
  • You want to use the hosted version without a subscription: an active subscription is needed even if you have credits left.

What you can do with it

  • Find keyword ideas with search demand, difficulty and live search results.
  • Check any website's backlinks and the sites linking to it.
  • Track where your pages rank for chosen keywords over time.
  • Crawl your website to find technical SEO problems.
  • See how AI assistants mention and cite your brand.
  • Let AI agents such as Claude or Codex run the research for you.

Software licence: OpenSEO is free and open source: running it yourself costs nothing for the app. You pay DataForSEO directly for the SEO data you use.

What this assumes

Typical use. Your own computer: The software runs on a computer you already own. You pay DataForSEO directly for the SEO data OpenSEO fetches.

  • Keyword searches (100 a month)$4.22 / month
  • Backlink checks (20 a month)$1.23 / month
  • Rank tracking (50 keywords checked weekly, about 217 checks a month)$0.41 / month
  • You already own the computer, so its price is not counted.
  • Electricity is not counted: it depends on your computer and where you live.
  • Typical use is OpenSEO's own calculator default: 100 keyword searches, 20 backlink checks and 50 keywords tracked weekly each month. Light use is half, heavy use is double.
  • Prices are OpenSEO's estimates for its hosted service with its stated 28% fee taken off, because people who run it themselves pay DataForSEO directly.
  • DataForSEO needs a minimum top-up of $50 and the balance never expires, so the first payment covers several months of typical use. New accounts get $1 of free credit.
