Ultraviolet Sophisticated Web Proxy May 2026

The glow from Leo’s monitor was the only light in the cramped bedroom, casting deep blue shadows against the walls. It was 2:00 AM, and he was locked in a digital chess match against the school's newly updated firewall. It was a ruthless, corporate-grade system designed to block anything remotely fun, educational, or outside the strict curriculum.

Access via https://your-domain.com – no login required (or add basic auth).

• Service Worker Support: It intercepts network requests at the browser level, allowing it to proxy things older proxies couldn't (like WebSocket connections, fetch API calls, and complex JS frameworks).
• Modern Compatibility: Works with sites like YouTube, Spotify, Discord, and Reddit.
• CAPTCHA Support: Handles reCAPTCHA and hCaptcha better than legacy proxies.
• Encoding: Uses advanced encoding schemes to bypass standard URL filters.

Captcha Support: It is capable of handling automated bot detection, including reCAPTCHA and hCaptcha.  Popular Projects Using Ultraviolet  ultraviolet sophisticated web proxy

Key Features

• High-performance forwarding: Asynchronous I/O and connection pooling minimize latency and maximize throughput for both short-lived and long-lived connections.
• TLS handling and interception: Supports TLS passthrough and optional TLS termination/interception (man-in-the-middle for inspection) with robust certificate management, pinning options, and strict validation to prevent downgrade or weak-cipher exposure.
• Layered caching: Multi-tier caching (in-memory, local disk, and distributed cache) with configurable TTLs, cache key customization, and cache-control compliance to reduce origin load and latency.
• Fine-grained access control: Role-based access policies, per-user and per-application rules, ACLs by IP, domain, URL path, HTTP method, and header patterns.
• Authentication and identity integration: Native support for OAuth2/OIDC, SAML, LDAP, and client-cert authentication; token introspection and session management.
• Traffic shaping and QoS: Rate limiting, bandwidth quotas, priority queues, and circuit breakers to enforce SLAs and prevent abuse.
• Observability and logging: Structured logs (JSON), distributed tracing (OpenTelemetry), real-time metrics (Prometheus), and request/response capture with redaction for troubleshooting.
• Extensibility: Plugin/extensions via WASM/JavaScript/Python for custom filtering, content transformation, or protocol adaptation.
• Policy and configuration management: Declarative configuration (YAML/JSON), dynamic reloads, and centralized policy management for clusters.
• Security features: Built-in protection against common web threats (HTTP smuggling, request-splitting), content scanning (malware/PII detection), and support for upstream proxy chaining and secure egress controls.
• Cloud-native deployment: Kubernetes-ready with Helm charts, sidecar modes, and service mesh integration.

Client-Side Configuration: Most processing happens in the browser, which increases speed and reduces server load compared to traditional "full-proxy" methods. Setup and Deployment The glow from Leo’s monitor was the only

Limited privacy; it does not provide full-system encryption like a VPN. Verdict Run via PM2 or systemd for persistence
