Envoy Proxy vs ngrok

Envoy Proxy is a free, open-source proxy for edge traffic and service-to-service communication in cloud-native and AI-native applications. It runs as a self-contained process outside the application and can serve software written in different languages. Envoy handles HTTP/1.1, HTTP/2, gRPC, and HTTP/3, with HTTP/3 documented as alpha. Traffic features include routing, retries, circuit breaking, rate limiting, request shadowing, and outlier detection. It exposes subsystem statistics, an administration interface, and distributed tracing through third-party providers. Security features include TLS, JWT, role-based access control, and OAuth-related authorization and authentication. Operators must configure protections such as watermarks, overload management, and circuit breakers for availability resilience. Installation options include Docker images for amd64 and arm64, macOS Homebrew, and static binaries. Its API is compatible with Envoy Gateway and Istio.

ngrok is a cloud networking platform that secures, transforms, and routes traffic to services wherever they run. Its agent sends traffic through secure tunnels without requiring firewall changes. Traffic Policy uses CEL-based rules to route requests, authenticate them, apply rate limits or web application firewall controls, and reject them. Supported traffic includes HTTP, TLS, and TCP, including WebSockets, gRPC, SSH, Postgres, MQTT, and Minecraft. The Integrations Hub offers integrations and guides for areas such as SSO, databases, Kubernetes, OAuth, webhooks, and web servers. ngrok also verifies webhook signatures for more than 70 providers, including Stripe, GitHub, Twilio, Slack, and Shopify. The free plan includes $5 one-time usage, up to 3 online endpoints, up to 1GB data transfer, up to 20k HTTP/S requests, and one team member. Paid access starts at $10/mo. On Hobbyist, endpoints stop working when usage credit runs out, until the billing cycle ends and credit resets. ngrok lists region pinning across the United States, Europe, Asia Pacific, Australia, India, Japan, and South America.
