The reason to buy
What this saves you from building
You are not paying for a file count. You are skipping the failure handling, verification, documentation, and operational edge cases behind the feature.
HTML/PDF text extraction
Use the documented CLI behavior and examples as a focused starting point.
Last-success change and failure verdicts
Run the included tests and synthetic example before using your own data.
What's included
Connected infrastructure, ready to adapt
- Direct HTTP(S) HTML and text PDF fetch
- Public destination, redirect, timeout and size checks
- Conservative robots.txt checks
- Normalized text hash comparison
- JSON CLI output with distinct exit codes
- Offline demo, tests, dependency notices, license and support terms
Typeset output evidence
Inspect the CLI, data, and QA results.
One card typesets verified output from the included synthetic local demo. This CLI kit has no browser UI.
Architecture
A small, inspectable workflow
Each step has a clear responsibility and can be adapted without turning the kit into a platform dependency.

License summarySupport
Product bugs and documented setup.
Support includes reproducible product bugs and documented setup questions. Custom development, project-specific integration, deployment, SLA, and perpetual updates are not included.
Support policyKnown limitations
Review the boundaries before buying.
- Monitor only permitted public URLs; no crawling or login access.
- DNS checks reduce SSRF risk but cannot eliminate DNS rebinding; use controlled egress for untrusted targets.
- Textless PDFs fail; a conservative robots parser is not a full implementation.
- Only the latest successful hash is retained locally.
