SEO and marketing decision
Seobility
A competent developer can build a narrow replacement that performs site audits, basic ranking checks, and simple backlink discovery, but matching Seobility’s scale, backlink index, advanced AI features, and enterprise limits is impractical without significant infrastructure and data investments.
Visit website↗Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Crawl a site, run on-page and technical checks, collect ranking snapshots for keywords, and display results in a dashboard with exports.
What it still won’t have
- Large-scale backlink index and historical backlink database
- High-frequency, large-site crawling limits and parallel crawler infrastructure
- White-label reporting and phone priority support
- AI-driven overviews and proprietary ranking/AI features
- Enterprise-grade uptime monitoring and SLAs
What remains hard

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted SEO monitoring service using Node.js (Express) + PostgreSQL + Puppeteer for crawling, and a lightweight React UI. Core features in scope: (1) scheduled site crawl that fetches pages and stores HTML, HTTP status and timing; (2) on-page checks (meta tags, broken links, duplicate detection) run against crawled HTML; (3) keyword ranking monitor that queries a configurable SERP provider API (or a pluggable mock) and stores daily position snapshots; (4) backlink discovery using a configurable third-party backlink API (pluggable) and basic backlink list view; (5) dashboard to view project status, re-run crawls, and export CSV. Out of scope: building a global backlink index, white-label PDF generation, AI content features, and enterprise-scale parallel crawling. Include error handling, retries and rate-limiting for external APIs, authentication for the UI, and unit/integration tests for crawler and ranking components.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
