Cursor now shows you demos, not diffs. Agents can use the software they build and send you videos of their work.

We use Cursor to make changes to Cursor and verify them end-to-end. Here, it is adding secret redaction to model tool calls. The agent records itself testing its local build of Cursor and comes back with a three-chapter video.

A third of the PRs we merge now come from agents running in cloud sandboxes.

Watch a demo:

missing @raycast up there fam

Just watched leerob's demo. You can TAKE OVER CONTROL of the VM at any time and just check it out from a link? Woah. Great release

vibing while cursor cooks a demo

Does this work only for web projects? Would be amazing if it also works for Mac and iOS apps.

Agent records a Loom walkthrough. Then agent joins standup to explain why it took 16 minutes. Then another agent watches the standup at 2x. Then agent re-records the Loom because a different agent gave feedback that the first one said ‘sorry let me reshare my screen’ too many times

Why would anyone want to watch a video of their own software? Rather than actually use it.

This is getting insane

WOW This is incredible, I can run an agent from my phone on the go Wait till its done, see a vid of what it did INCREDIBLE TIMES!

whoever chose the bg painting thing has excellent taste

cursor innovating again love to see it

We're making setup free! Go to and watch Cursor onboard itself to your codebase. It is still surprising to me how well this works.

So stoked about this!

This is literally the update I needed now. Potentially the video, could be used for marketing...

‘maybe in Berlin this would work’ 😭😭😭

We need this for app dev!

Got it running Unity & playing the game, pretty neat the possibilities!

crazy W

Hugee

Cost? Pro plan expiring in one day? 😊

That's awesome! Working on something similar for other coding agents @RangerNetHQ

We’re moving from code review to behavior review.

We went from “trust the diff” to “watch the screen recording” real quick

Agents demoing their own work is wild. thoughts on the next unlock: agents transacting the value of that work - truly peer-to-peer, no platform tax, at machine speed. The UI layer is solved. The settlement layer is next. Unicity

someone add this to OpenInspect!

Does this work on iOS apps running on a simulator?

this is directionally correct, well done

can it run mobile apps? would love to see an agent test on android or ios

If agents can clone features in 5 minutes, then the moat shifts from code to ecosystem.

IDE = Integrated DEMO environment?

Demos over diffs is the real unlock. Agent builds in Cursor → tests secret redaction in a live instance → hands you chapters 1–3 as video proof. ⅓ of merged PRs already agent-written. Latency feels local. Takeover from mobile works. This is the future arriving early. Insane work @cursor_ai

Wait this is fire

'Demos not diffs' shifts verification from code review to QA. You stop asking 'is this correct?' and start asking 'does this work?' Different skill, different bottleneck. Engineers who thrive next are the ones who know what working looks like, not what correct code reads like.

Super cool
