Crawling your own site and flagging broken links or missing meta tags is a genuinely bounded weekend build. Screaming Frog's depth — hundreds of technical SEO checks refined over years — is a different scale.
VIBE SCORE 97/100
The parts this build actually needs, each rated on its own — the average is the Vibe Score above.
| Landing page | 99 |
| CRUD database | 95 |
Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $43–$86 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |
Screaming Frog costs $22/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 4 months.
Borderline. Crawling your own site and flagging broken links or missing meta tags is a genuinely bounded weekend build. Screaming Frog's depth — hundreds of technical SEO checks refined over years — is a different scale.
Screaming Frog costs $22/mo (about $264/yr) as of 2026-08. That's what a working rebuild would save you.
Comprehensive technical SEO checks (duplicate content detection, canonical tag validation, structured data errors) accumulate into a large, specialist rule set over years Crawling at scale (millions of pages) without overwhelming the target site needs real rate-limiting and infrastructure care JavaScript-rendered page crawling needs a headless browser, a heavier dependency than simple HTML fetching
