Host a C++ file and share it as a link

Put a .cpp file at a public address that displays as readable source.

You can host:

Free to use. Your CPP file is live at your-name.99helpers.site in about ten seconds.

What is a .cpp file?

C++ extends C with object orientation, templates and a large standard library, and it dominates games, high-performance computing and anything where control over memory matters. A .cpp file is source that compiles to a native binary.

What people use CPP files for

  • Algorithm implementations and competitive programming solutions
  • Teaching material
  • Code shared for review
  • Examples in documentation

What opens a CPP file

  • Any browser, which displays it as text
  • g++, clang and MSVC
  • VS Code, CLion, Visual Studio and every editor

How to host a CPP file

  1. 1

    Drop your CPP file in

    Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.

  2. 2

    Pick an address

    Type a name and we'll tell you straight away whether it's free. That becomes the link: solution.99helpers.site

  3. 3

    Publish and share

    Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.

The same three steps work for any file — see how file hosting works on 99helpers.com.

What happens when someone opens the link

The source displays as text with formatting intact.

Why host a CPP file instead of emailing it?

Competitive programming solutions and algorithm examples get shared constantly, and a link beats a paste that loses its indentation.

Worth knowing before you publish

  • Never include API keys, tokens or credentials — the file is public and can be indexed.
  • Note the language version and any dependencies in a comment, so whoever reads it knows what it needs.
  • For multiple files, upload the folder rather than each file separately.

CPP hosting questions

Will the C++ code display or download?
It displays as text in the browser, with formatting and indentation exactly as uploaded — so people can read it before copying or running anything.
Is it safe to host source code publicly?
The file is readable by anyone with the link, so it's fine for code you'd put in a public repository and wrong for anything containing keys, tokens or credentials.
Can I host a whole project?
Yes — upload the folder rather than a single file and it publishes as a set of files, or host a .zip of the project for people to download.
