Frequently Asked
Everything you need to know before getting started.
What is CollabX?
CollabX is a real-time collaborative IDE that lets students or developers code together in a shared workspace with voice communication, a collaborative whiteboard, chat and instant multi-language code execution — all in real time at one place.
Why do we need to use CollabX over other online IDEs?
CollabX combines real-time code collaboration (sub-100ms sync via WebSockets), built-in voice communication (WebRTC via Agora), a collaborative whiteboard, role-based access control, and session persistence — all in a single browser-based platform with no installation required.
Is CollabX completely free to use?
Yes. CollabX has a fully functional free tier with no credit card required. You can create workspaces, collaborate in real-time, execute code, use the whiteboard, and voice chat. The Pro plan (₹99/month) extends session duration to multiple hours, increases participant limits, and unlocks premium visual effects.
Does it support mobile version?
CollabX is designed exclusively for desktop and laptop screens. The collaborative code editor, whiteboard, and voice interface require a full keyboard and adequate screen real estate. Accessing CollabX on a smartphone or tablet is not supported and will result in a restricted experience.
Can I use CollabX for technical interviews or student learning and coordination?
Yes — CollabX is built for both. For technical interviews, hosts get full role-based control: assign Editor or Viewer permissions, observe candidates typing in real-time, and run code instantly without any third-party tool. For students and educators, CollabX makes pair programming, group assignments, and live code reviews seamless — a teacher can guide, a student can code, and everyone stays in sync. The collaborative whiteboard also doubles as a digital blackboard for explaining logic and algorithms.
