💻 Real-Time Collaborative Editing

This is a true live code editor — when you or a collaborator types, everyone in the session sees the change appear instantly. There’s no refreshing, no exporting files, and no copy-pasting code back and forth over chat or email. It feels like you’re all typing into the same document, because you are.

🌈 Supports All the Languages You Actually Use

Write code with proper syntax highlighting in:

• JavaScript
• Python
• PHP
• HTML
• CSS
• Java
• C++

Colour-coded syntax makes code easy to read and easy to follow, even when several people are editing different parts of it at once.

🔗 Start a Session and Share It in Seconds

• One-Click Session Creation — open the tool and you have a live coding session ready to use immediately
• Shareable Session Link — every session gets its own unique link; anyone with the link can join
• Email Invitations — send a clean, ready-made invitation email to bring a collaborator into your session
• Invite Multiple People at Once — bring your whole team into the same session in one go
• Share via Slack, Teams, or Direct Link — send your session wherever your collaborators already are
• See Who’s in the Session — a live participant list shows who’s currently online and active

⚙️ Control How Your Session Works

• Read-Only Mode — let some people just watch and follow along while others do the editing
• Auto-Save — your code is saved automatically as you type, so nothing is ever lost
• Line Numbers — turn line numbers on or off depending on how you like to read code
• Session Expiry — sessions can be set to stay open for anywhere from 1 hour to a full week
• Participant Limits — keep a session capped to a set number of people if you need to

🎨 A Comfortable Place to Code

• Fullscreen Mode — toggle fullscreen with one click for a distraction-free coding view, great for interviews or focused pairing
• Light & Dark Themes — switch to whichever theme is easier on your eyes
• Friendly Notifications — simple, unobtrusive alerts let you know when something happens in your session
• Works on Any Device — the editor is fully responsive, so it works just as well on a laptop, tablet, or phone

🗂️ Never Lose Your Code

• Automatic Version History — every change made during a session is tracked, so earlier versions of the code aren’t lost if something goes wrong
• Upload or Download Code — bring existing code into a session, or take a copy of the current code with you when you’re done, when this option is turned on

🔒 Private and Safe to Use

• Your code and session data stay where you’re using the tool — nothing is sent off to unrelated third-party services
• No tracking scripts or analytics are built into the editor itself
• No account or sign-up is needed to join a shared coding session
• Requests within a session are handled securely, protecting your session from common web-based attacks

This makes CodeShare a safe option even when you’re working with code you’d rather keep private.

👥 Who Is This Tool For?

• Developers who want to pair-program or debug together remotely, in real time
• Interviewers and candidates running or taking a live coding interview
• Teachers and students working through programming concepts together
• Teams who need a quick, no-signup way to collaborate on a snippet of code
• Freelancers and clients reviewing or fixing code together without extra tools
• Anyone who just needs to share and edit code with someone else, right now
