Drop a folder.
Get a link.
Thirdpass turns anything you or your AI agent builds into a live website in seconds. Share it with your team, a few people, or everyone. Nothing to set up, nothing to maintain.
How it works
Three things to know. That's the whole platform.
- 01
Put it online
Drag a folder onto the Mac app, or ask your AI agent to publish it. Seconds later it has its own web address, named after the folder.
- 02
Share it
Every site has one setting: your team, specific people, or everyone. Thirdpass handles sign-in, so a client just opens the link.
- 03
Keep improving it
Anyone on the team can pick a site up, change it, and publish again. Changes merge instead of overwriting, and one click undoes a bad update.
Made for agents
Your agent builds it. Thirdpass puts it in front of people.
Thirdpass is for work you do with an AI agent such as Claude Code. Point the agent at a Thirdpass folder once. From then on it knows how to build for the platform and publish there without help.
It publishes on its own
Ask for a site and get a link back. The agent knows how to put its work on Thirdpass, update it, and undo it, without you touching anything.
Everything it needs is included
Every site can save information, update live, and tell who is looking at it. There are no servers, accounts, or keys to set up first.
Feedback goes straight back
Leave comments on the live site. One click turns the thread into a brief your agent can act on, so the next round of changes starts from what you actually said.
See who is there with you
Live cursors show who else is on the page, and follow mode lets you look over their shoulder while you talk it through.
