Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site
Free to use. Your RB file is live at your-name.99helpers.site in about ten seconds.
What is a .rb file?
Ruby is a dynamic language designed for programmer happiness, best known for Rails. A .rb file is plain-text source — interpreted rather than compiled, so the file is the program.
What people use RB files for
- Utility scripts shared with a team
- Examples in documentation and tutorials
- Rake tasks and automation
- Gem source shared for review
What opens a RB file
- Any browser, which displays it as text
- Ruby itself, on every platform
- VS Code, RubyMine and every editor
How to host a RB file
- 1
Drop your RB 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
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: script.99helpers.site
- 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, so it can be read before it's run.
Why host a RB file instead of emailing it?
Pasting code into chat mangles the formatting. A hosted file preserves it and gives you a URL to reference from documentation.
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.
RB hosting questions
- Will the Ruby 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.
