Hammer vs HTTPGlass

Hammer is a professional HTTP and HTTPS debugging toolkit for developers, QA engineers, mobile teams, and technical users who need a clear way to inspect, analyze, and troubleshoot network traffic on iPhone and iPad. Whether you are testing an API, debugging a mobile app, checking request headers, reviewing response data, or exporting sessions for deeper analysis, Hammer helps you understand what is happening between your app, website, and backend services. Designed for local-first network inspection, Hammer keeps captured data on your device by default. Requests, responses, headers, cookies, and session history remain local unless you choose to export or share them. How Hammer Works: Hammer uses Apple's public Network Extension framework and a Packet Tunnel Provider to enable on-device traffic capture. When you tap Start and approve the iOS system configuration prompt, Hammer creates a local Packet Tunnel. Traffic included in the active capture session is routed through Hammer's local proxy process on the same device, where requests and responses can be inspected and displayed. The Packet Tunnel does not connect your traffic to a remote VPN server. Hammer does not provide anonymous browsing, change your virtual location, or hide your public IP address. iOS displays VPN-related permission text and may show a VPN status indicator because Apple manages Packet Tunnel Provider configurations through its VPN configuration infrastructure. Key Features: Live Traffic Capture Capture HTTP and HTTPS requests in real time. Review method, host, path, status code, protocol, timing, size, and request details in a clean debugging interface. Detailed Request Inspector Inspect URL parameters, request and response headers, message bodies, status codes, timing metrics, and content types. HTTPS Debugging Use optional certificate-based HTTPS inspection in development, testing, or other authorized environments. Certificate installation and trust are controlled by the user through iOS Settings. Request History Keep capture sessions organized locally so you can revisit traffic, compare results, and investigate issues after testing. Rules and Filters Manage rules for bypassing hosts, blocking traffic, rewriting requests, mapping responses, and controlling traffic during debugging. HAR Export Export captured sessions as HAR files for desktop analysis, bug reports, team collaboration, or long-term debugging records. Local Proxy Workflow Use Hammer's on-device Packet Tunnel and local proxy workflow to inspect traffic from apps, browsers, and services you are authorized to analyze. Clean Debugging Interface Work with readable request lists, structured detail views, protocol statistics, favorites, and practical tools for repeated debugging. Local-First Privacy Captured network content is processed and stored locally by default. Hammer does not require an account, and the Packet Tunnel does not upload captured traffic to a remote VPN server. Data leaves your device only when you explicitly export, share, or submit it through a user-initiated action. Hammer is useful for: • Debugging mobile app API requests • Inspecting HTTP and HTTPS traffic • Reviewing headers, cookies, and response bodies • Testing backend services and REST APIs • Checking status codes, redirects, and timing • Exporting HAR files for issue reports • Managing traffic rules during development • Investigating network behavior during QA testing Hammer is intended for legitimate development, testing, and debugging workflows. Use it only with apps, websites, services, and network traffic that you own or have permission to inspect.

See every request your apps make — from your iPhone, with no Mac and no cable. HTTPGlass is a full HTTP(S) debugging proxy that runs entirely on-device. It installs a local VPN profile and its own root certificate, then captures and decrypts traffic from the apps on your phone the way a desktop proxy would. Nothing is relayed through a server and there is no account to create. CAPTURE • Every request and response, with status, method, host, timing and size • HTTPS decryption through an on-device root CA you install and trust yourself • HTTP/1.1 and HTTP/2, gzip, deflate, Brotli and chunked bodies decoded for you • Full-text search across URLs, headers and bodies • Sessions: browse, scope, rename, share and delete each capture run READ • Body viewers: pretty JSON, tree, field list, raw and hex • GraphQL inspector — operations and variables, not a wall of escaped text • WebSocket frame viewer • Image and form-body previews • Export to HAR, or generate a cURL / Swift / Python / JavaScript / Kotlin snippet CHANGE • Breakpoints — pause a request or a response, edit any header or the body, then send it • Map Local — answer a request with a mocked response, no backend needed • Map Remote — send a request to a different host or path • Rewrite — rules that add, replace or remove headers, query items and body text • Scripting — onRequest and onResponse hooks in JavaScript, run on-device against live traffic • Compose and replay any request • Network Condition — throttle bandwidth and add latency to test on a bad connection CONTROL • Block, Allow and SSL Proxying lists so you only capture what you care about • No-Cache rules • Face ID / Touch ID app lock over captured traffic • iPad split view: the traffic list and the detail side by side PRIVACY Captured traffic never leaves your device. No cloud relay, no account, no advertising identifier. Optional, opt-in usage analytics and crash reports can be turned on or off at any time in Settings, and they never include captured traffic — no hostnames, URLs, headers, bodies or certificates. FREE AND PRO Free includes capture, decryption, every body viewer, search, sessions, export, code generation, one Block pattern, one Allow pattern, one SSL Proxying pattern and one request + one response breakpoint pattern. HTTPGlass Pro unlocks unlimited Block / Allow / SSL Proxying patterns, Decrypt all, No-Cache, Map Local and unlimited breakpoints. $8.99/month or $39.99/year with a 3-day free trial. Payment is charged to your Apple ID, subscriptions auto-renew unless canceled at least 24 hours before the end of the period, and you can manage or cancel anytime in Settings ▸ Apple ID ▸ Subscriptions. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://httpglass.com/privacy/ Requires iOS 18. HTTPGlass debugs traffic from apps on this device only — it is a developer tool, not a network monitor for other people's devices.
