Stirling PDFWhat you're getting
Stirling-PDF is a complete PDF workbench in your browser: merge, split, rotate, compress, convert, watermark, sign, redact and OCR: fifty-plus tools in one app.
Every business handles PDFs it should not paste into a random "free converter" website: contracts, IDs, financials. On CoreHost, Stirling-PDF runs on your own instance in your region, so sensitive documents never leave infrastructure you control.
On CoreHost
- Fifty-plus PDF tools including OCR and redaction
- Documents processed on your instance, never a third-party site
- No file-size or files-per-day metering
- Optional login so only your team can use it

Included with every appStandard, not add-ons
Daily backups, one-click restore
Every instance is backed up daily. Restore any snapshot yourself from the panel. No support ticket, no fee.
SFTP file access
Direct SFTP access to your app's data folders. Your files are never locked away from you.
Custom domain + auto TLS
Bring your own domain with a CNAME and a TXT verification record. Certificates are issued and renewed automatically.
AI + human support
A 24/7 AI engineer that can actually inspect and fix your app, with a human escalation path. App-level help included.
Automatic updates with rollback
Each update is tested on a copy and backed up first, and rolled back automatically if the app fails its checks.
Per-app firewall
Restrict access to the IP addresses you choose, with an Add my IP button. Off by default.
Backups to your own S3
Add encrypted, incremental backups to your own S3-compatible storage on top of the daily ones we include.
Resize any time
Move up or down a tier from the panel. Your balance is drawn by the hour, so you pay the new rate from the change.
