What is Cursor and Why It’s the #1 Code Editor in 2026
Cursor is a VS Code fork rebuilt from the ground up for AI-first development. Over 3 million developers (including teams at OpenAI, Anthropic, Google DeepMind, and thousands of startups) use it daily.
Core Features of Cursor in 2026
- Instant model switching: Claude 3.5 Sonnet ↔ GPT-4o ↔ Gemini 1.5 Pro ↔ Llama 3.1 405B
- Cursor Tab – best-in-class code completion (beats GitHub Copilot X)
- Cursor Composer – generate entire files or projects from natural language
- Chat with full repository context (millions of tokens)
- AI Code Review, automated refactoring, bug detection
- 150+ languages & frameworks support
- Zero-knowledge mode for private repos
- Cursor Pro – 500 fast requests/month + unlimited slow
Why Cursor is Completely Blocked in Russia & Belarus
Cursor uses frontier models classified under U.S. ECCN 5D002. The company is legally required to block access from sanctioned jurisdictions. Since mid-2025 the block is airtight:
- Registration and login forbidden
- Cursor Tab & Chat return 403
- Desktop app refuses to start
- API access blocked

How a VPN Works – Developer-Friendly Explanation
A VPN establishes an encrypted tunnel between your machine and a remote server. All traffic is encrypted client-side (AES-256-GCM or ChaCha20), routed through the VPN node, and only then decrypted. Your ISP sees only encrypted packets; Cursor sees only the VPN server’s IP. KelVPN adds post-quantum Kyber-1024 + Dilithium-3, making interception impossible even for future quantum computers.
Real Problems a VPN Solves for Cursor Users
- Geo-blocking & sanctions – solved by IP change
- Corporate/university firewalls – solved by traffic encryption
- Public Wi-Fi eavesdropping – solved by end-to-end encryption
- ISP throttling on large project uploads – solved by traffic obfuscation
- Risk of proprietary code leaks – solved by audited zero-logs + decentralization
Note: VPNs can bypass geo-restrictions and certain forms of internet filtering, but always respect local laws and Cursor’s Terms of Service.
Kill Switch Explained – Why It’s Critical for Cursor
A kill switch instantly terminates your internet connection if the VPN tunnel drops, preventing accidental IP/DNS leaks. KelVPN’s kill switch operates at kernel level with <50 ms reaction time – essential when working with commercial or classified code.
Security Best Practices When Using Cursor + VPN
- Always enable Kill Switch
- Turn on DNS/IPv6/WebRTC leak protection
- Use only independently audited no-logs VPNs (KelVPN audit 2025)
- Never store Cursor passwords in browser
- Enable 2FA on Cursor account
- Run ipleak.net test after connecting
- Use split-tunneling: only Cursor traffic via VPN
- Keep both KelVPN and Cursor updated
