OpenAPI Viewer is the easiest way to explore, test, and understand OpenAPI 3.0 and 3.1 specifications on your Apple devices. Whether you're integrating a third-party API, reviewing your team's documentation, or testing endpoints on the go, OpenAPI Viewer gives you a clean, native interface built for developers. EXPLORE YOUR API Open any JSON or YAML OpenAPI file and instantly browse all endpoints organized by tag. Search across operations, schemas, parameters, and examples in seconds. View rich documentation for every endpoint — including descriptions, parameters, request bodies, and responses — with schema constraints, validation rules, and example values displayed clearly. TRY IT OUT Send real HTTP requests directly from the app. Fill in path, query, header, and cookie parameters, provide a request body, configure authentication, and hit Send. View the response body, status code, duration, and validation results — all without leaving the app. EXPORT AND SHARE Copy any request as a cURL command, JavaScript fetch, Swift URLSession, or Python httpx snippet — ready to paste into your terminal or codebase. BUILT FOR APPLE PLATFORMS A thoughtfully designed native UI makes even complex, sprawling APIs easy to read. Color-coded methods, clear badge indicators, and structured layouts — built for Apple platforms from the ground up. FREE TO USE OpenAPI Viewer is completely free with no subscriptions or paywalls.

Coolidash puts your self-hosted Coolify instances in your pocket. Connect one or more Coolify servers over HTTPS with an API token, then watch and control your infrastructure from your iPhone. WHAT YOU CAN DO • See applications, services and databases in one filterable list • Start, stop and restart any resource • Redeploy an application, or rebuild it without cache • Read build logs, with live refresh while a deployment runs • Check machine health: reachability, proxy and resource counts • Revalidate a server that went unreachable • Get notified when a build starts, succeeds or fails BUILT FOR PEOPLE WHO SELF-HOST Your API tokens never leave the device. They live in the iOS Keychain and are never written to files or logs. Coolidash talks straight to your own server: no Coolidash backend, no proxy, no third party in the middle. Every sensitive action - stopping a service, restarting a database, redeploying - asks for Face ID or your passcode first. Coolidash is an independent app. It is not affiliated with, endorsed by, or connected to the Coolify project. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
