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. If you find it useful, you can support development through an optional tip jar — entirely your choice.

Read full description

gitbay is a CLI-first git forge. This is its iOS client: somewhere to read, review and respond when you are away from a keyboard. Sign in with a token you mint over SSH. There is no password, no browser flow, and no account with us — the app talks only to the instance you name, and the token stays in the device Keychain. BROWSE - Files, directory trees, and syntax-highlighted source - Commit history, a single commit with its patch, and blame - Branches, tags, and full-text search across a repository - READMEs and wikis, rendered as Markdown or Org REVIEW - Merge requests with the diff, file by file and hunk by hunk - Review threads anchored to diff lines, with replies and resolution - Approve, request changes, and merge with the strategies the server allows TRIAGE - Issues with labels, assignees, and milestones - Open, edit, comment, and close from the phone - Signature verdicts shown on every commit WATCH - A dashboard of what waits on your review, what is assigned to you, and what is still open - CI builds with their logs, and a trigger for any job the config names - Releases, organisations, teams, and profiles Every screen is backed by a command the server already exposes, so the app cannot drift from what the CLI and the web can do. Requires your own gitbay instance. gitbay is free software; the forge and this client are developed in the open at gitbay.org.
