Nothing to say.

[Collab Space @collabspaceapp]

A live video feed + a shared real-time canvas is such an underrated combo. Is it for engineering system design? Virtual tutoring? Remote tabletop gaming? Yes to all.

You can build the infrastructure, but you never truly know how the end user is going to use it until you ship.

[Collab Space @collabspaceapp]

Never trust a client to disconnect gracefully. Always build your server-side cleanup logic assuming clients will frequently vanish into thin air.

[Rajeev Dewangan @rajeevdew]

Real-time sync tip: Stop using HTTP polling for your collaborative canvas. We pipe all our Fabric.js state changes directly through WebRTC Data Channels. Getting that sub-50ms latency on a shared whiteboard changes everything.

[Collab Space @collabspaceapp]

The Canvas Sync Layer:

We use Fabric.js on the frontend. But to keep drawing perfectly in sync without lag, we bypass standard HTTP polling entirely.

Instead, we multiplex the canvas state over low-latency WebRTC Data Channels. Sub-50ms sync. No lag.

Been quiet lately because @umairulla05 and I have been heads down building this!

We engineered a custom SFU video backend and paired it with a crazy fast, infinite canvas. Really proud of how this is shaping up.

Give @collabspaceapp a follow to see what we ship next! 👇

Seamless ideation means your conversation and your whiteboard live in the exact same workspace.

Collab Space is a real-time meeting platform where your video and your shared whiteboard live in the exact same place.

Follow along for updates as we gear up for launch.

@ChaiCodeHQ Thanks man. Try tapping on about section content in phone and hovering in big screen devices.
Tried giving different experience for both.
However the site needs to be optimised.
