No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Periodically fetch monitored pages, parse links to the target domain, diff current vs previous link attributes/status, store results, and send alerts when changes are detected.
What it still won’t have
- Polished commercial UI/UX and onboarding polish
- Mass scale infrastructure for thousands of concurrent checks
- Lifetime deal pricing and vendor-hosted convenience
- Any proprietary analytics or marketing content bundled by the vendor
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a backlink monitoring web app using Python (FastAPI) + Postgres + Redis + Celery, with a simple React frontend. Core features: user signup (single-user support), add domains and individual backlink page URLs, crawler worker that fetches pages (use Playwright or requests with configurable timeouts and rate limits), parse anchor tags and rel attributes, store snapshots and detect diffs (status active/lost/broken, dofollow/nofollow, anchor text changes), scheduled checks (weekly/other intervals), email notifications via SendGrid, CSV import/export of backlinks, and an events dashboard showing history. Out of scope: multi-tenant billing, advanced SEO analytics, and third-party integrations beyond email. Include robust error handling, retry/backoff for fetching, tests for crawler/parser/notification logic, Docker-based deployment, and a README with run and maintenance instructions.
How we checked
How the score was reached
- Build verdict base78
- Price verified on pricing page+3
- Evidence score81
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.
