Apache Traffic Server vs LocalXpose

Apache Traffic Server is a free, open-source caching proxy server for HTTP/1.1 and HTTP/2. It stores frequently requested pages, images, and web service calls so they can be reused, with the stated aims of improving response time and reducing server load and bandwidth needs. It can also add keep-alive behavior, filter or anonymize requests, and balance traffic through a proxy layer. Deployment patterns include web proxy cache, reverse proxy, and cache hierarchy. As a layer 7 HTTP load balancer, it can choose next-hop servers using request attributes, weighted round robin, or URL consistent hashing. Plug-in APIs let teams add behavior such as changing headers, handling ESI requests, or implementing cache algorithms. Security options include client access controls and authentication, SSL termination, and SSL-based access control. It is self-hosted, with Linux and macOS listed as platforms. The project identifies enterprises, internet service providers, backbone providers, and large intranets as its intended audience. The listed stable release is 10.2.0; 9.2.15 is listed as the long-term support release.

LocalXpose is a reverse proxy for making services on a local machine reachable from the public internet through tunnels. It supports HTTP and HTTPS, including WebSockets, alongside TCP, TLS, and UDP. Users can work through a command-line interface or graphical interfaces, including a desktop app for sharing previews. The product includes authentication, rate limiting, IP whitelisting, header editing, and a built-in file server on all plans. Traffic logs cover HTTP, TCP, and UDP, and webhook payloads can be inspected, modified, and replayed. Custom and wildcard domains and automatic Let's Encrypt certificates for custom domains are available. The maker says tunnel hosts terminate at its edge with TLS 1.2+ encryption; users can configure scoped access tokens, IP allow lists, and authentication plugins. Starter is free and allows two active HTTP or HTTPS tunnels, with time limits and an interstitial warning page. PRO costs $8 a month, billed annually at $96/yr, and supports 10 tunnels. LocalXpose runs on Linux, macOS, Windows, web, and self-hosted environments.
