Open Platform: SMS FoxBox

SMS FoxBox is not a closed appliance.

It’s an on-premise, open, and fully integrable SMS gateway, built to fit your infrastructure—not force you into someone else’s roadmap.

With FoxBox you get:

• a complete Linux-based platform,

• guaranteed root access,

• publicly available source code,

• modern, well-documented APIs.

The result: faster integrations, zero lock-in, and maximum flexibility.

Open by design — no vendor lock-in

Many hardware SMS gateways are reliable but closed:

when you need a special workflow, a custom protocol, or a new integration, you’re stuck waiting for the vendor.

FoxBox removes that limit:

• you can audit how the system works,

• you can extend it with your own developers,

• you can integrate any internal software without depending on a proprietary roadmap,

• you can keep evolving the platform over time.

If an integration doesn’t exist today, it’s not a blocker:

with open code and root access you can build it yourself—or with us—without waiting on closed-box updates.

Hybrid integration: local SIMs and/or cloud providers

FoxBox is a true hybrid SMS gateway:

• send/receive via standard local SIM cards,

• or route traffic through external SMS aggregators such as:

  • Twilio

  • Infobip

  • and many others both SMPP 3.X, HTTP and SMSC protocols

So you can always choose the best path:

• local SIMs for independence and predictable costs,

• cloud providers for scalability or international coverage.
