OpenSEO
Open source alternative to Semrush and Ahrefs
OpenSEO is an SEO tool for the people. If tools like Semrush or Ahrefs are too expensive or bloated, OpenSEO is a pay-as-you-go alternative that you actually control.
All-in-one SEO tool for you and your AI agent.
Connect with any agent like Claude Code, OpenClaw or Hermes. We have pre-built skills, but you can build your own to tailor OpenSEO to your needs.

Self-Hosting
OpenSEO supports two self-hosting paths:
- Simple: Docker (Best for testing it out) - For personal use on your own machine. See
docs/SELF_HOSTING_DOCKER.md.- Unless you already are self-hosting other apps and are confident doing so, we recommend self-hosting with Cloudflare as opposed to Railway, Coolify or Dokploy.
- We plan to make it simpler to host on those platforms in the next few months.
- Recommended: Cloudflare - For internet-facing self-hosting across multiple devices or with your team (works on the free plan). See
docs/SELF_HOSTING_CLOUDFLARE.md.
Either way, you need a DataForSEO API key to get SEO data. See docs/DATAFORSEO_API_KEY.md.
Costs
OpenSEO needs a DataForSEO API key so that you can get SEO data. You pay them directly when self hosting.
When you self host, your costs will be slightly lower than the estimates on our website. The way the hosted service makes money is by charging 28% extra for every request we make to DataForSEO.
Local Development
