Identity and delivery, as services.
Two systems we operate as standalone products. CIP handles identity. GSM Gateway handles delivery. Together they're the backbone of every system we ship — and they're available to license, integrate with, or fork.
CIP — Identity broker
secure.omerbilgin.org · OAuth2 + CIP-Pure
Centralized identity service used by our own production platforms. Handles phone, email, Telegram and WhatsApp logins. Validates TC kimlik numarası. Cross-platform identity unification — same person across multiple apps gets one identity, deduplicated.
Auth0 cost, KVKK compliance, multi-platform SSO requirement. Self-hosted, in your jurisdiction.
Maintenance momentum slowed since March 2026. Single point of failure if the instance goes down. We're working on an HA strategy — saying it up front.
Laravel client example

$user = $cip->loginWithPhone(

otpCode: '123456'
);OAuth2 token
curl -X POST https://secure.omerbilgin.org/api/v1/oauth/token \

-d "grant_type=password" \
-d "username=905XXXXXXX" \

gsm.omerbilgin.org · 16+ consumer platforms
Unified gateway for SMS (GoIP + VatanSMS), WhatsApp (WAHA + MyWhatsApp Baileys), voice (Asterisk + IVR callback), and TTS (ElevenLabs).
Telecom-level cost per SMS via GoIP (~0.05 TL). Twilio equivalent (~3 TL) — meaningful annual savings.
Multi-session WhatsApp failover: jupiter/default/Matsev pool, automatic switching via resolveWorkingSession().
Send SMS via GSM Gateway
curl -X POST https://gsm.omerbilgin.org/api/v1/sms/send \
-H "X-API-Key: YOUR_SITE_KEY" \
-d "to=905XXXXXXX" \
