Fake Code Generator for Screenshots, Mockups and Fake Coding Screens

This fake code generator writes believable source code that does nothing. Pick a language and it builds imports, functions, loops, conditions and comments with consistent variable types, then colors the result like a real editor. Use it when you need code on screen but cannot show a real repository.

Everything runs in your browser. Copy the fake code text, download it as a file, save a PNG of the editor window, or play it back as a fake code screen that types itself in fullscreen.

What You Can Do With It

Fake coding screen that types itself

Press Type it out, choose a slow, normal or fast speed and go fullscreen. It works for videos, streams, demos and harmless pranks.

Fake code text to copy and paste

One click copies plain text without line numbers. Downloads keep the right extension, such as .py, .js or .java.

Fake code image (PNG)

Save the editor window with its theme, line numbers and filename tab for thumbnails, slides and documents.

12 languages

JavaScript, TypeScript, Python, Java, C++, C#, Go, PHP, Rust, HTML, CSS and SQL, each with its own syntax, imports and naming style.

Editor themes

VS Code Dark and Light, Dracula, Monokai, GitHub Dark and a green Matrix theme. Changing the theme never changes the code.

Repeatable results

Every result has a seed. Enter it again with the same settings to get identical code, or generate new code for a fresh version.

Languages and Complexity Levels

Use JavaScript or TypeScript for web app snippets, Python for scripts and data work, Java, C# and C++ for enterprise and game-style code, Go and Rust for systems-style code, PHP for backend pages, HTML and CSS for front-end markup and SQL for database queries.

Simple keeps functions short and flat. Medium adds loops and nested conditions. Complex allows deeper nesting and try/catch blocks in languages that have them. The line slider runs from 10 to 500 lines and the output always has exactly the number you choose.

What Makes the Fake Code Look Real

Real code has structure, so the generator plans the file before it writes it: imports first, then functions or a class sized to fit your line count. Variables get types that match how they are used, loops walk lists that exist, and Python blocks are never empty.

Names come from a developer vocabulary such as user, order, session and cache, written in each language style: camelCase in JavaScript and Java, snake_case in Python and Rust, PascalCase in C# and Go. Comments are optional.

Where Fake Code Comes in Handy

Screenshots and documentation

Fill an editor screenshot, a README or a tutorial without exposing private company code.

Videos, streams and thumbnails

Set a coding or hacker scene with a screen that types itself, without recording real code.

Website and app mockups

Give code blocks realistic content in Figma, landing pages and product screens before the final text exists.

Slides and training

Create placeholder examples for decks, courses and templates where the code only has to look right.

Interface testing

Check how long code blocks, scrolling and syntax highlighting behave in your own design.

Developer marketing

Prepare images for ads, blog posts and product pages with code that looks real and reveals nothing.

Good to Know

The code is filler for display. It is not a working program and should not be presented as real work or shipped in a product.

How this Fake Code Generator works

This fake code generator writes source code that looks real but does nothing. It plans the file first: a few imports, then functions or a class sized so the output has exactly the number of lines you choose. Inside each function it remembers which variables it has declared and what type they are, so conditions, loops and returns only use values that exist and fit together.

Colors come from a small syntax highlighter that knows the keywords, types, strings, numbers and comments of each language. You can switch editor themes, hide line numbers, change the text size and choose whether comments appear. Type it out plays the code back one character at a time, and fullscreen turns the editor into a fake coding screen.

Every result is produced from a seed. The same seed with the same language, complexity, length and comment setting always gives the same code, so you can recreate a screenshot later. Everything runs in your browser, and nothing you generate is uploaded.

How to use this Fake Code Generator

1

Pick a language and length

Choose one of 12 languages, set the complexity and pick between 10 and 500 lines. The code updates instantly.

2

Style the editor

Choose a theme such as VS Code Dark, Dracula or Matrix. Changing the theme, text size or line numbers never changes the code.

3

Copy, download or save an image

Copy the text without line numbers, download the file with the right extension, or save the editor window as a PNG.

4

Turn it into a fake coding screen

Press Type it out, choose a speed and go fullscreen. Space pauses and Esc exits.

Example Usage

The same settings and seed always give the same fake code:

Input
Language: Python · Complexity: Medium · Lines: 14 · Seed: 7
Output
# Background job helpers import logging from datetime import datetime # Temporary workaround until the migration lands def create_metric(offset: int) -> bool: emails = ["[email protected]", "[email protected]", "[email protected]"] try: email = "[email protected]" sizes = [732, 33, 14, 91] print("processing:", offset) except Exception as err: print("operation failed:", err) return False

Frequently Asked Questions

What is a fake code generator?
A fake code generator creates believable source code that does nothing useful. It works like lorem ipsum for developers: you get realistic functions, loops, conditions and comments to fill a screenshot, mockup, video scene or slide without showing real code.
How do I make a fake coding screen?
Generate code in your language, press Type it out, choose a typing speed, then press Fullscreen. The code types itself onto a full-screen editor. Press Space to pause and Esc to leave. If you would rather trigger the typing with your keyboard, use the Hacker Typer tool.
Can I copy and paste the fake code?
Yes. Copy code puts plain text on your clipboard without line numbers, ready to paste into Figma, slides, a document or a code block. Download file saves it with the right extension for the language, for example .py or .java.
Can I save fake code as an image?
Yes. Save as PNG exports the editor window exactly as you see it: theme colors, line numbers, filename tab and text size. Very long code is scaled down so the image stays within what browsers can draw.
Which programming languages are supported?
12 languages: JavaScript, TypeScript, Python, Java, C++, C#, Go, PHP and Rust, plus HTML, CSS and SQL. Each one uses its own syntax, imports, naming style and comment format.
Is the fake code real or runnable?
It is built to look like valid code, with balanced blocks, consistent variable types and no empty functions, but it is filler. It does nothing useful and may leave variables unused, so treat it as display text and not as a working program.
Can I get the same fake code again?
Yes. Every result has a seed number. Enter the same seed with the same language, complexity, length and comments setting and you get identical code. Generate new code picks a fresh seed.
Is anything uploaded to a server?
No. The generator, the syntax highlighter and the image export all run in your browser. Nothing you create is sent to a server.
Does this make fake ZIP codes, QR codes or verification codes?
No, this tool creates programming code. For fake postal codes and addresses try the Random Address Generator or the Random ZIP Code Generator, and for QR codes or barcodes use the QR Code Generator or the Barcode Generator.
