## Coddy

Coddy is a web-based coding education platform built around doing rather than watching. Instead of long video lectures, learners work through short interactive lessons in the browser, then immediately apply what they learned in an integrated playground with a compiler or interpreter. The catalogue spans web development (HTML, CSS, JavaScript, TypeScript, React, Next.js, PHP, Django), general-purpose languages (Python, Java, C#, Go, Ruby, Kotlin, Lua), systems work (C, C++, Rust, Assembly, Verilog, Solidity) and mobile development (Flutter, Dart, Swift, SwiftUI).

Beyond single languages, Coddy organises guided learning paths that mirror real job roles: Software Engineer, Frontend Developer, Full Stack Developer, Backend Developer, Data Analyst, Data Scientist, DevOps Engineer and several game-development tracks for Unity, Godot and Roblox. There are also recently added non-programming subjects such as pre-algebra, algebra, geometry, trigonometry, physics, chemistry and chess, aimed at learners who want one place for both STEM coursework and coding practice.

Coddy can be started for free, and the platform uses a freemium model with premium plans for additional content and features. The site is protected by Cloudflare, so automated crawlers may be blocked while normal browsing works fine. Please check the official pricing page for current plan details, since we do not list prices we could not verify.

**Pricing & Plans:** Free to start with optional paid plans. Coddy uses a freemium structure with premium tiers for extra content, learning paths and playground features; exact current prices should be confirmed on the official pricing page.

- **Interactive lessons in the browser:** Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
- **Built-in playgrounds and compilers:** Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
- **Career-oriented learning paths:** Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
- **Daily challenges and gamification:** Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.
- **STEM subjects beyond code:** Maths, physics, chemistry and chess courses let learners practise quantitative subjects step by step alongside their programming track.

**Strengths:** Very broad catalogue covering web, systems, mobile, data, game development and even non-programming STEM subjects; No setup required: lessons and playgrounds run entirely in the browser; Guided job-role learning paths make it easier to know what to learn next; Free to start, so you can evaluate the teaching style before paying

**Limitations:** The huge number of tracks can be overwhelming for complete beginners deciding where to begin; Depth per topic may be lighter than a dedicated deep-dive course or textbook; Some premium content requires a paid plan, and pricing must be checked on the site

## TechScreen

TechScreen is a desktop application built around a single promise: giving candidates real-time answers during interviews without the interviewer knowing. It works for coding rounds, system design, and behavioral interviews, accepting questions either typed in or captured from your system audio, which means it can pick up what an interviewer is saying on a call and surface an answer almost immediately.

The core technical claim is that invisibility comes from the operating system rather than a visual workaround. The app window is excluded from screen capture at the platform level, so when you share your screen on Zoom, Microsoft Teams, Google Meet, Webex, Amazon Chime, CoderPad, Codility, HackerRank, or similar tools, your audience sees the interview question but not the assistant's answer. The site notes that Zoom 6.16+ requires enabling window-filtering in the screen-share settings, and states that platform compatibility is re-checked daily.

The interface is designed around keyboard shortcuts so nothing on screen hints that help is being requested. Screenshots, conversation mode, sending answers, hiding the window, and repositioning it are all bound to hotkeys, and the window floats above your IDE, browser, and call. Users can configure programming language, spoken language, role, and custom prompts, and the vendor advertises that no user has been detected to date.

**Pricing & Plans:** TechScreen offers a free trial that does not charge a card, after which you pick a subscription plan. The company states every plan includes the full app, there are no hidden fees and no $1,000-plus tiers, and you can change or cancel at any time. Check the official pricing page for current amounts.

- **Screen-share invisibility:** The app window is excluded from screen capture by the operating system, so it does not appear in Zoom, Teams, Meet, or session recordings.
- **Typed and audio question capture:** Reads questions from typed text or live system audio, so answers appear as soon as the interviewer finishes asking.
- **Keyboard-only control:** Show, hide, move, and send responses entirely through keyboard shortcuts, with no mouse movement that could give it away.
- **Custom prompts and profiles:** Set your programming language, spoken language, role, and custom prompts so answers match the interview you are walking into.
- **Multi-format interview support:** Covers software engineering, product, and other roles across programming and behavioral formats, with no visible app icon in the dock or tray.

**Strengths:** Invisibility is implemented at the OS level, so it survives screen shares and recordings.; Reads live system audio, letting it react to spoken questions quickly.; Keyboard-only operation keeps the workflow discreet during a call.; Supports coding, system design, and behavioral rounds across languages and roles.

**Limitations:** Only macOS 13+ and Windows 10+ are supported; no Linux build is listed.; On Zoom 6.16+ users must manually enable the window-filtering screen-capture setting for invisibility to hold.; Using an interview assistant raises genuine ethical and policy questions with employers and interview platforms.; Effectiveness still depends on the candidate explaining answers convincingly rather than just reading them.
