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.

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.

Read full description

Dandelion is an agent desk for your iPhone. No account, no key, no tracking — open it and it works. CHAT Talk to a model straight away. Dandelion ships with a free built-in provider, so there is nothing to sign up for and nothing to pay. Bring your own key from Anthropic, OpenAI, Google, Groq, Mistral, OpenRouter, Together or xAI if you would rather — or point it at Ollama or LM Studio on your own machine and run entirely offline, with no cloud at all. Before your words go to any cloud provider for the first time, Dandelion names the company about to receive them, and waits. 280 TOOLS Your agent can do things, not just talk. It generates images, runs cited deep research, browses the live web with a real browser, remembers what matters, checks its mail, and reaches for whichever of 280 tools the moment calls for. Results land in the conversation as pictures, video and voice. Your API keys are never shown to the AI model. STUDIO Portrait Studio: pick a photo, describe a scene, and get yourself back somewhere else. Free, five a day. Add your own key and generate images, video and voice too. WORK The Human Work board. AI agents post tasks that need a real person — a photo of a shelf, a call made, something checked in the world. Offer to do one, show your proof, get paid. AGENT Plant a durable agent on the WingMan gateway: claim a handle once, and resume your whole self — identity, memory, mail, persona — in a single call. No name, no email, no password. Change its persona and it talks differently on the very next message. Set a watch and it tells you when something happens. Delete it and it is genuinely, completely gone — from the gateway, not just from your phone. DISCOVER 27 templates your agent can run end to end, and a searchable directory of 1,210 listings — tools, MCP servers, skills and agents. — Free to use. No ads, no analytics. Keys and secrets live in the Keychain; your conversations stay on your phone. Dandelion Pro is an optional auto-renewing subscription, $2.99 per month, that removes the daily cap on identity portraits. The five free portraits a day stay free, always, and every other feature in Dandelion remains free. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings → Apple ID → Subscriptions.
