Which frameworks does SitrTech support?

Python: Odoo, Frappe/ERPNext, Django, Flask, FastAPI and Tornado. PHP: WordPress, Laravel and generic PHP projects — nine frameworks in total.

How does SitrTech protect my source code?

Every file is sealed with authenticated AES-256-GCM under its own unique key, then executed by a compiled per-OS/arch/Python native loader. The master key lives only inside that native binary, never in readable code, and each build can be bound to an expiry, domain, IP range, MAC, machine-id, hostname, disk serial or Odoo database.

Will encryption slow down my application?

The impact is negligible. Protected code runs at ordinary Python speed once loaded — there is only a one-time load per module at first import (about 0.1s), and the app then runs fully offline with no per-call cost.

Does my source code get uploaded to SitrTech?

In local mode your source never leaves your machine — encryption runs on your side and only line counts are metered for billing.

Can I lock a protected build to a customer or a machine?

Yes. You can bind a build to an expiry date, a domain, an IP/CIDR range, a MAC address, a machine-id, a hostname, a disk serial or an Odoo database. The rules are enforced locally at runtime and cannot be edited or bypassed.

What platforms does the protected code run on?

Python 3.8 to 3.14 on Linux, macOS and Windows. The same protected build runs everywhere, including fully offline.
