Hammer vs Marshal Stack

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.

Marshal Stack is one screen for everything you have already shipped. Your apps in the App Store, the sites and APIs behind them, the servers you run yourself and the coding agents working on your projects — all read by one rule: green is fine, amber needs a look, red is down. WHAT IT WATCHES • App Store — rating, review count, latest version, and the release state: in review, rejected, live. • Sites and APIs — checked every minute, with the latency next to the result. A notification arrives when an address stops answering twice in a row, and again when it recovers. • Your own servers — CPU, memory, disk, load and the heaviest processes, reported by a small agent you install with one line on a machine you already own. • Cloud servers — connect a read-only Hetzner Cloud token and see your servers' status, CPU, disk and network next to the rest. • Alerts that say what to do, not only what broke — memory over the threshold, a process running from /tmp, a port that was not open yesterday. WAITING FOR YOU When an agent working on your project needs a decision, the question appears on Home and in a notification. Answer with one tap or a typed reply; risky actions ask you to unlock and confirm. The first answer wins everywhere. AGENT USAGE See how much your Claude Code agents used: the 5-hour and weekly usage limit, when it resets, and tokens by task, project, role and model over 7 or 30 days. YOUR KEYS, YOUR MACHINES Connect your own App Store Connect key, Hetzner token and GitHub repositories, or none at all. The server agent dials out over HTTPS: it opens no port, reads no files, touches no databases, and uninstalls with one command. There is no registration form. Sign in with GitHub, or just open the app and look around on sample data bundled inside it — no account, no keys, no network. ON THE WRIST The same three states on Apple Watch, plus your projects ranked worst first. A glance tells you whether anything needs you, and a tap opens the one thing that does. THIRD-PARTY SERVICES Marshal Stack works with services you connect yourself: GitHub (sign-in and repositories), App Store Connect (app ratings and release state), Hetzner Cloud (read-only server inventory), Trello and Telegram (optional task boards and alerts), and Claude Code (the coding agents whose questions and usage you see). Marshal Stack is an independent app and is not affiliated with, endorsed or sponsored by GitHub, Hetzner, Trello, Telegram or Anthropic. No ads, no third-party trackers.
