Phone systems quietly run the world, and almost nobody outside the industry understands how they work. Sazrika Foundation is a small effort to change that, one free tool and one plain-English explanation at a time.
When I started digging into how calls actually work, SIP, WebRTC, the whole stack underneath every phone call, I kept hitting the same wall. The knowledge was either buried in hundred-page specifications, written for people who already understood it, or locked inside tools that cost far more than they should.
Learning it was harder than it needed to be. So I started building the tools and writing the explanations I wished I had when I began.
Sazrika is built and maintained by one person who is genuinely fascinated by how telephony works. I am an enthusiast first. I build these tools because I use them myself, and because every time I finally understand something, it feels wrong to keep it to myself.
There is no company behind this, no investors to please, and nothing to upsell you. Just a real interest in this corner of technology and a belief that the people learning it next should have an easier time than I did.
Everything on Sazrika is free to use, with no account and no sign up.
Free, and meant to stay that way. No ads, no selling your data, nothing hidden behind a subscription. The tools run entirely in your browser where they can, so your logs and numbers never leave your device.
Running the parts that do cost money, some API calls and hosting, is covered by people who find the tools useful and buy a coffee through Ko-fi. That is the entire business model, and it is enough.
