OpenSEO

OpenSEO is an open-source SEO platform positioned as an alternative to Ahrefs and Semrush, built for a workflow where a person and an AI agent work the same data. It covers the core research surface — keyword discovery with volume, difficulty, intent and live SERPs; domain overview and organic traffic estimates; backlink and referring-domain analysis; rank tracking over time; and technical site audits — plus an AI-visibility section that tracks how often a brand is mentioned and cited in AI answers, and a prompt explorer for comparing responses across models.

Priced by usage, not by seat

The economics are the point. Rather than a $100-plus monthly subscription, OpenSEO runs on your own DataForSEO API key and you pay for the requests you actually make. Self-hosting is free; the hosted service is $10 per month and funds itself with a margin on upstream data calls. Self-hosting runs through Docker for a single machine or Cloudflare for an internet-facing team deployment on the free plan.

Built for agents

OpenSEO exposes an MCP server so agents such as Claude Code, Codex, OpenClaw and Gemini can query real SEO data instead of improvising advice, and ships a set of Agent Skills — keyword research, keyword clustering, competitor analysis, site audit, link prospecting and a coaching mode — that give an agent a documented procedure for each workflow rather than a bare tool list.

Open source

MIT licensed and developed in the open by Every App, Inc. The codebase is a normal application you can fork and modify, which is the stated alternative to waiting on a vendor roadmap. It launched on Product Hunt on 19 July 2026 at #1 for the day and has gathered several thousand GitHub stars.
