Difficulty is an editorial estimate of technical and operational complexity, not a score.
Short startup notes by Startup Ideas. A longer read is added only after it is written for this launch. Last reviewed Oct 6, 2026. How we read a launch.
The problem
Coding agents edit a front end and then guess what it looks like.
Who would pay for this?
Developers using a terminal coding agent on web apps.
How could it make money?
A possible model is open source. That is an editorial guess from the shape of the launch, not a published price, and not evidence that Zenbu uses it.
What would the MVP look like?
A command that opens the local site beside the session.
Original product launch
This launch is inspiration and evidence that someone shipped, not a partnership. The idea above is our reading of the broader opportunity. Zenbu did not write it.
