Code Blink – Real‑time Collaborative Code Editor
Code Blink is a lightweight yet powerful real‑time code editor that lets you collaborate with teammates instantly. No complicated setup. No servers. Just create a room, share the 4‑digit code, and start coding together. Whether you are pair programming, conducting a remote interview, or teaching code live, Code Blink makes collaboration seamless and fun.
Key Features
Real‑time Collaboration
Write, edit, and review code together in real time. Every keystroke is synced instantly across all connected devices. Multiple cursors show who is typing what, so you always stay in sync.
Simple Room System
Create a room and get a unique 4‑digit code. Share the code with your teammate and they can join in seconds. No need to create accounts for everyone – just share the room code and start.
Live Participants List
See exactly who is in the room. The participants list shows everyone’s display name and email. A live online count badge keeps you updated about active collaborators.
Send Invites to Registered Users
Want to invite a teammate who already uses Code Blink? Use the mail feature to send a custom message directly to any registered user. They will receive your invite on their dashboard under “Received Invites” and can join your room instantly.
Copy All Code
Need to save or share your work? Tap the copy button to copy the entire editor content to your clipboard in one click.
Leave Room Confidently
Finished your session? Use the Leave Room button to remove yourself from the participants list. Your teammates will see the updated list automatically.
Cross‑Platform
Works on Android, iOS, web, tablet, and desktop. Your team can use whatever device they have. The editor adapts to any screen size.
Fast & Secure
Built with Flutter and Firebase Realtime Database. Code syncs with minimal latency. Data is transmitted over encrypted channels, and room links are unguessable.
No Ads, No Distractions
CodeBlink is completely free and ad‑free. No hidden costs, no subscriptions. Just pure collaborative coding.
