Portal – self-hosted E2E TLS tunnel for localhost (ngrok alternative)
by sjc02183·Mar 6, 2026·1 point·0 comments
AI Analysis
●●●BangerWizardryShip It
Inverts tunnel model with E2E TLS passthrough; self-hosted beats ngrok's vendor lock-in.
Strengths
- •Solves NAT/firewall barrier by reversing connection direction—outbound from app to relay, not inbound
- •Genuine architecture insight: keyless E2E TLS means zero code changes to existing apps
- •Permissionless relay design lets users run their own infrastructure on any domain
Weaknesses
- •Relay operator risk: hosting untrusted relays introduces abuse surface (DDoS, illegal content hosting)
- •Early stage: 205 stars, minimal production evidence; ngrok/Tailscale have 10+ years maturity
