About

Veloterm

Features
Read full description

Veloterm is a fast, native SSH client for iPhone and iPad with a built-in AI assistant. Connect to your remote servers over SSH and work in a full xterm-256color terminal powered by SwiftTerm — with an AI helper that can suggest, explain, and fix shell commands. SECURE BY DESIGN • Host-key pinning (TOFU): a changed server fingerprint refuses the connection to defend against man-in-the-middle attacks. • Passwords and private keys are stored only in the iOS Keychain — never synced, never logged. • App Transport Security enforced. The app talks only to the SSH hosts you configure and, for AI, to Anthropic's API. AI ASSISTANT — BRING YOUR OWN KEY • Suggest, Explain, and Fix commands right from the terminal. • Uses YOUR OWN Anthropic API key, stored in the Keychain and called directly from your device. No middle-man server, no analytics, no tracking. FAST & NATIVE • SwiftUI interface for iPhone and iPad, with split-view multitasking. • Password or private-key authentication. • Import and export your host profiles. VELOTERM PRO • Free: save up to 20 hosts. • Pro (one-time purchase): unlimited saved hosts plus profile export/import. Veloterm is an SSH client — it connects to servers you control and does not run a shell on the device.

About

HeaderX

Features
Read full description

HeaderX injects custom HTTP request headers into your Safari browsing session — the essential companion for web developers, API testers, and QA engineers. Point HeaderX at your development environment, define your headers once, and flip them on whenever you need them. No proxy setup, no configuration files, no leaving the browser. DEFINE HEADERS AS JSON Describe your headers in a simple JSON editor — paste an entire set at once: {"X-Debug-Mode": "enabled", "Authorization": "Bearer dev-token"} Or use the array format to keep headers saved but individually switched off. TWO VIEWS, ONE TOGGLE Edit as raw JSON or flip to List view, where every header gets its own checkbox. The master toggle in the corner turns everything on or off instantly — your configuration stays saved either way. REUSABLE PROFILES Save named header sets — one per project, environment, or test scenario — and switch between them in two clicks. FEATURES • One-tap master toggle • JSON editor and checkbox list views • Per-header enable/disable • Named profiles for quick switching • Settings persist across browser restarts • Works in Private Browsing (optional) GOOD TO KNOW Standard header names (Authorization, Accept-Language, User-Agent, and other HTTP-spec headers) are applied to all requests through Safari's native rule engine. Custom header names (X-My-Header and similar) are applied to fetch and XHR requests made by web pages — a Safari platform constraint on custom names in network rules. For typical API-debugging workflows, this covers exactly the requests you care about. Headers apply to every site while the toggle is on — remember to switch off when you're done testing, especially with authentication headers. PRIVACY FIRST Everything stays on your device. HeaderX collects no data, phones home to no one, and contains no analytics. What you configure is nobody's business but yours.
