What is UWAS?

UWAS replaces your entire web server stack and hosting control panel with a single Go binary. Auto HTTPS, built-in caching, PHP support, .htaccess compatibility, reverse proxy, WebSocket forwarding, WAF, multi-user access control, and a 38-page React dashboard with 205+ API endpoints.

One binary. Zero hassle.

Current Snapshot (v0.0.38)

• Dashboard pages: 38 (web/dashboard/src/pages)
• Admin API routes: 205+ (route registrations under /api/v1 in internal/admin/api.go)
• Go packages: 52 (from go list ./...)
• CLI commands: 19
• Test status: go test -p 1 ./... passing

Architecture

Request Flow:

  TCP → TLS (SNI routing)
    → HTTP Parse
      → Middleware Chain:
          Recovery → Request ID → Security Headers → Rate Limit → Access Log
        → Virtual Host Lookup
          → Per-domain: IP ACL → Rate Limit → BasicAuth → CORS → Header Transform
            → Security Guard (blocked paths, WAF)
              → Bandwidth Check (throttle/block)
              → Rewrite Engine (mod_rewrite compatible)
              → Cache Lookup (L1 memory + L2 disk)
                → Handler:
                    ├── Static File    (ETag, Range, pre-compressed, SPA)
                    ├── FastCGI/PHP    (connection pool, CGI env)
                    ├── Reverse Proxy  (5 LB algorithms, circuit breaker)
                    ├── WebSocket      (TCP tunnel, bidirectional pipe)
                    └── Redirect       (301/302/307/308)
              → Cache Store
              → Bandwidth Record
    → Response
