## Already using Screaming Frog or Sitebulb?

Both are good crawlers, and both are rentals. The difference is what happens when you stop paying.

| Price | $279 once | $279/yr | subscription |
| CLI & automation | | | — |
| CI/CD pipeline integration | | via CLI | — |
| AI analysis (Claude, GPT, Gemini) | BYOK | BYOK | read-only MCP |
| Runs on your machine | | | desktop |
| No crawl cap on a paid licence | | | 10k–500k URLs per audit |
| Keeps working if you stop paying | | free 500-URL mode | — |
| Source code guarantee | | — | — |
| Future updates included | forever | while licence is active | while subscribed |
| Cost after 2 years | $279 | $558 | 2 × annual plan |

Screaming Frog charges $279 every year. You pay $279 once, and it keeps running after year one.

Screaming Frog has its own CLI, scheduling and AI prompt integrations, so credit where it’s due — what it doesn’t have is a one-time licence. Sitebulb Lite ($180/year) caps audits at 10,000 URLs and Pro ($425/year) at 500,000. [Full pricing comparison](https://www.blackseoanalyzer.com/en/seo-crawler-pricing).
