Describe it.
Watch it get built.
Perennis is your AI engineer — it plans, codes, tests and deploys real software in a private workspace, then puts it live on the web with one click.
Fast, Cowork, and Code
One conversation, three modes. Fast is instant chat with no workspace. Cowork handles research and reports. Code opens an isolated engineering environment.
Publish in one click
Every project can go live instantly on its own address, with free hosting and automatic HTTPS. Bring your own domain or buy one right here.
Agents that work for you
Create named agents, hand them assignments, and come back to a finished report. Your projects keep running even when you close the tab.
Works everywhere
Phone, tablet or laptop — Perennis is a full development studio in the browser. Download your code anytime; it is always yours.
