Experiments and small free tools.

• CheckNet (چک‌نت)
  A free network check tool in Persian and English, made with Iranian users in mind. See your IP, check for WebRTC, DNS and VPN leaks, test for filtering, and measure speed and bufferbloat. Run ping, traceroute, DNS, HTTP, port and SSL checks from probes around the world. Also included are DNS lookups compared across four resolvers, whois and RDAP, ASN and hosting lookups, an email (SPF, DKIM, DMARC) health check, record builders, an in-browser CSR maker and everyday encoders, plus step-by-step guides in both languages. No ads, tracking or login, and it works offline.
• chikoja (چی‌کجا)
  Hospitals and ERs, pharmacies (24/7 first), fuel and CNG, Red Crescent, fire stations, police, drinking water and safe open spaces for about 1,500 Iranian cities and towns, with national emergency numbers at the top of every page. In Persian, light enough for any phone, and it works offline. Save a city to your phone, or forward its one-file pack in a chat. The data comes from OpenStreetMap and is rebuilt every week. No accounts, ads or tracking.

• PriceDB
  Free-market Iranian Rial (IRR) rates for currencies, gold and coins, updated every 30 minutes on Cloudflare Workers and D1. A live prices page, a free public API with charts, a Telegram bot with price alerts, an MCP server for AI assistants, and the full history as a monthly open dataset. Running since 2023.
