API Testing Tool vs DevSnap

API Testing Tools is a fast, private HTTP client for your iPhone, set like a newspaper. Write a request, send it, and read the answer in clean type, with the timings, headers and checks that matter. THE DAILY REQUEST • A front page with today's sends, what needs your attention, your slowest endpoints and the requests you pin, ready to send in one tap. REQUESTS • Every method, query parameters, headers, and JSON, form, XML, text or GraphQL bodies. • Bearer token, Basic and API-key authentication. • {{Variables}} and environments: switch between staging and production in one tap. Built-in {{$uuid}}, {{$timestamp}}, {{$isoTimestamp}} and more. • Paste a cURL command from docs or your browser, or import a Postman collection or environment. RESPONSES • Pretty-printed JSON that keeps the server's key order, raw text with search, image and HTML previews. • Fields: every value in a JSON response with its path. Tap one to check it or save it into a variable. • Status, size and where the time went: DNS, connect, TLS, waiting and download. • Live streams: watch server-sent events arrive as they happen, with event names, ids and timings. CHECKS AND CHAINS • Checks on every response: status, response time, headers, body text and JSON paths. • Save a value from a response into a variable, like a login's token, and use it in the next request. • Run a whole collection in order and see at a glance what passed and what needs a look. AND • A history of every send with its full response, and a filter for what failed. • Copy any request as cURL, or export it as HTTPie, JavaScript, Python, Swift or Go. • Export and import your library as JSON. • Self-signed certificates for local dev servers (optional), cookies, timeouts and redirects under your control. • Light and dark editions. Free, with no ads, no tracking and no account. Requests go straight from your iPhone to the servers you call; nothing passes through anyone else. An optional "Buy me a coffee" tip supports the developer and unlocks nothing.

DevSnap turns technical screenshots into clean, reusable developer notes. Import a screenshot, capture with the camera, or paste text or an image. Text Scan is selected by default and recognizes code, logs, JSON, stack traces, and terminal output on your device. It works offline and does not upload your input to the DevSnap transform service. Need richer structure? Switch to optional AI Transform to turn a selected image into organized Markdown, plain text, a summary, or a Mermaid diagram. DevSnap clearly identifies this cloud-processing mode before upload. See the result before you scan: - Open built-in JSON, TypeScript error, and npm log examples - Preview finished results without granting Photos access - Examples do not enter History or use AI Transform credits Use every result: - Copy cleaned text with one tap - Export Markdown or a language-specific source file - Create a polished Share Card from a cleaned excerpt - Share Cards exclude the original screenshot by default - Render Markdown as a readable document, then edit its source - Rename, favorite, search, and reopen saved snippets Your searchable history is stored locally on your device. No account is required. DevSnap does not use your content for advertising or tracking. AI Transform is optional and requires an internet connection. When enabled, the selected image, transform setting, and an app-generated device identifier are sent to DevSnap's processing service.
