Python IDE & Jupyter vs Hitchecker

Zero-setup Python IDE that runs your code offline, an AI coding assistant, and a developer toolbox — in a first-class citizen app for iPad and iPhone. Juno is designed to cover all your Python coding needs, supporting both Python scripts (.py) and Jupyter notebooks (.ipynb) — a document format focused on applying Python to data analysis and computational science. FREE FEATURES - Navigate and manage files and folders, quickly preview documents and media - Browse and edit Jupyter notebooks in a powerful, customizable notebook editor with beautifully rendered previews — editing is free - Write and edit code sources, scripts, JSON, XML, and other text-based formats — one versatile editor for code and text alike, with syntax highlighting - Add quick access bookmarks for file system locations outside the app's sandbox, or simply open documents in place PRO FEATURES Only one thing in Juno is Pro: running code. Even that is free to try — a generous trial allowance lets you run notebooks, scripts, projects, and the REPL before you buy. After the trial, running code unlocks with a one-time Pro purchase — not a subscription. - Run Jupyter notebooks, Python scripts, and whole projects locally with the built-in Python 3.13 interpreter and a full suite of up-to-date, preinstalled scientific and data packages — entirely offline - Explore interactively in a Python REPL — open a standalone prompt, or drop into it after running a script or project to keep exploring what it defined - Search the variables, functions, and imports in your session with the Object Inspector — no need to print each one - Open any folder as a project: file tree, multiple editor tabs, run any script, with a coding assistant aware of the whole project - Keep side outputs — Preview, Browser, Console, Object Inspector — open as side-by-side tabs in an output sidebar - View local web servers and HTML your code produces in a built-in browser with developer debug tools - Long-running scripts and Jupyter sessions keep going in the background - Automate with Shortcuts and Siri: App Intents run a Python file, run Python code, or open a file — pass arguments and files, capture output, and chain actions - Leverage powerful data analysis, machine learning and developer tools: NumPy, pandas, Matplotlib, SciPy, Scikit-learn, OpenCV, LXML, and more - Enjoy painless package management: install any pure Python package with an intuitive package manager AI CODING ASSISTANT The assistant runs on your key, not ours: add your OpenAI, Anthropic, or Gemini API key, and requests go straight from your device to your provider. You control what you spend and share — Juno never takes a cut. PYTHON MEETS iOS Reach native iOS APIs straight from Python with the built-in juno modules: clipboard, Keychain, device info, location, motion sensors, contacts, reminders, photos, sound, notifications, sharing, and Bluetooth. Show native alerts and pickers, present full-screen image, video, and web previews, or call into UIKit, Foundation, and any Objective-C framework via the Objective-C bridge. PYTHON SCRIPTS Python scripts are plain-text Python source code files with a .py extension. Juno lets you work on these with snappy, intelligent code completion, a console with full terminal emulator support, and a built-in media viewer for code-generated images, plots, web apps, and more — executed by the embedded Python interpreter, locally on your iPhone or iPad and completely offline. JUPYTER NOTEBOOKS A Jupyter notebook is a versatile document format that stores live code, markdown text, plots, images, and LaTeX equations in a single .ipynb file. Notebooks keep a record of every input and output of an interactive session, embedding rich output (HTML, images, video, plots) right in the document — a perfect playground for data analysis, machine learning, and computational science, and Juno makes working with them a breeze!

Most tools for proxy configs begin with the config. Hitchecker begins with the network you are already on: the address the internet sees you at, how it is classified, and which DNS resolvers your iPhone is really asking. The links other people hand you come after that. WHAT YOUR CONNECTION LOOKS LIKE FROM OUTSIDE The Network tab opens with what iOS already knows, before anything leaves: Wi-Fi, cellular or wired, metered, Low Data. Ask for the full check and our server describes the address your request arrived from — the public IP, where it maps to, the operator and network type behind it, and a risk figure with a word beside it. Reputation flags — VPN, proxy, Tor, hosting — appear when they apply. WHO IS ANSWERING YOUR DNS Which resolvers this device uses is read locally, then identified: operator, country, and whether it is a public resolver or your network's own. Their answers get checked too. Three anchor names — dns.google, one.one.one.one and dns.quad9.net — are looked up twice, once through your own resolvers and once through Cloudflare's public DNS, which nothing on your local network can rewrite. Agreement reads as nothing unusual; disagreement is shown as an observation, with the addresses that came back. A measurement, not a verdict. AND A SERVER THAT ISN'T YOURS For VLESS, VMess, Trojan and Shadowsocks you can ask whether the server is still alive — five a day free, unlimited on Pro. Your iPhone stays out of it: the link goes to a server we run, which makes the connection itself and reports whether it answered, the round-trip time, throughput each way, and the same portrait of the address traffic would surface from. WHAT ACTUALLY LEAVES THIS IPHONE No account. No analytics. No advertising. No third-party SDKs. Hitchecker carries none of your traffic and never connects your device to a config you inspect. Only these go out, each at your request: the connection check's own request; the addresses of your DNS resolvers, so the tester can name who runs them; the canary lookups to Cloudflare; the config link you choose to test; a subscription URL fetched from your provider. Both checks sit behind a one-time consent screen, and the tester runs under a no-logging policy for links and IP addresses. THE LINK ITSELF, OPENED ON THE DEVICE Paste text, scan a QR code, pick a screenshot out of Photos, or send a link from another app. Twelve formats are decoded on the device: VLESS, VMess, Trojan, Shadowsocks, ShadowsocksR, Hysteria, Hysteria 2, TUIC, SOCKS, HTTP proxy, WireGuard and OpenVPN. Each becomes plain labeled rows — transport, encryption, Reality keys, server names, fingerprints, timeouts — and fields Hitchecker cannot place get their own heading. Secrets stay covered until you tap them. THIRTEEN CHECKS, GRADED NOTE, RISK OR SEVERE Certificate validation switched off, a password in the clear, no transport encryption, ciphers long past trustworthy, an empty server name, sample credentials nobody replaced, half-configured Reality, a WebSocket on a plaintext port. Whatever fires is listed with its grade — Note, Risk or Severe — for everyone, and a clean config is told so in full, paid or not. Pro adds the reasoning behind each finding and what to change. A LIBRARY THAT CAN BE SWITCHED OFF Free keeps 40 configs and 15 favorites, searchable; Pro removes the ceiling. Want no history at all? Switch saving off and, from then on, no analyzed config is stored on the device — anything saved earlier stays until you delete it, and your own settings are kept locally either way. Any config can be passed on as a QR image, or as a text file when it is too big to scan — large OpenVPN profiles usually are — with a reminder that either carries the password. PRO, PAID ONCE, NEVER A SUBSCRIPTION Past unlimited testing and history: batch work on many links, a subscription URL or an imported file; two configs compared field by field, where both sides must be the same format; your library exported as Text, Markdown or JSON.
