HTTrail vs PrismKit

HTTrail is a native network inspection workbench for developers building and testing apps on iPhone, iPad, and Mac. Capture and decrypt the HTTPS traffic from your own device, inspect every request and response down to the byte, then compose and replay requests with a full-featured API client. Everything runs on-device. No account, no backend, no analytics, no ads — your traffic never leaves your device. INTERCEPTING PROXY • Decrypt HTTPS with an on-device certificate authority that mints per-host certificates on the fly • Inspect headers, bodies, timing, and raw hex for every flow • Block, redirect (map local / map remote), rewrite requests and responses, throttle, and set breakpoints • SSL-proxying allowlist so pinned apps keep working • Export captures as HAR API CLIENT • Compose GET, POST and more with params, headers, auth, and structured bodies (JSON, form-urlencoded, multipart) • GraphQL, pre-request and test scripts, and live response preview • Organize requests into collections with environments and history • Import from cURL, OpenAPI 3, and Postman v2.1 • Generate code: cURL, Swift, JavaScript, Python REALTIME • Connect and test WebSocket, Server-Sent Events, Socket.IO, and MQTT • Built-in local test server PRIVATE BY DESIGN HTTrail captures only your own device's traffic, with your explicit consent, and keeps it on your device. No data is collected. Nothing is ever sent to us. HTTrail is a developer tool for debugging and testing your own apps and APIs.

PrismKit is a developer's Swiss Army knife: a collection of fast tools that run entirely on your iPhone and iPad — offline, with nothing ever sent to a server. Paste a production token, a private config, or any sensitive data with confidence. Everything is processed locally on your device. TOOLS INCLUDED • JSON ↔ YAML — Convert between both formats in either direction. • JSON ↔ TOON — Convert to and from TOON, the compact format that saves tokens when working with AI models. • JSON Format — Format, validate, and minify with error detection. • Base64 — Encode and decode text. • URL Encode — Encode and decode URL strings. • JWT Decoder — Inspect the header and payload, see the expiry, and verify the HMAC signature (HS256, HS384, and HS512). • Hash — Generate SHA-256, SHA-512, and MD5. • QR Code — Generate and customize QR codes with colors, a logo, and PNG export. • UUID — Generate unique identifiers in batches. • Regex Tester — Test regular expressions and see matches and their groups. • Diff — Compare two versions of text line by line and spot the differences. BUILT TO BE FAST • Command palette (⌘K) to jump to any tool in seconds. • Mark your favorite tools to keep them within reach. • Copy any result with a tap. • Optimized for iPhone and iPad, with a two-column layout on larger screens. • Light, dark, and automatic themes. PRIVACY FIRST • 100% offline: no tool needs an internet connection. • No accounts, no analytics, no ads, no tracking. • We collect absolutely no data. Made by developers, for developers.
