A product studio, powered by Harbor
We ship products. Harbor builds them with us.
LastLap is a small studio making apps for iPhone and the web. Most of them start as a sentence on Harbor, our AI platform, go live the same day, and the ones people use get built out from there. Everything below is live, and every link goes to the real thing.

How Harbor powers it
One platform behind the whole portfolio.
Harbor is the AI platform we built to make apps, websites and agents from a plain-English description. We use it for our own products first, which is why it keeps getting better at the things a real product needs.
- 1
Describe it
A product starts as a plain-English description on Harbor. Harbor's agents write the brief, build it, review it and fix what the review finds.
GutenTag, Roomie Ref and Charter all started this way.
- 2
Put it live
It goes up at a real address the same day, with sign-in, saved data and payments built in. Real people use it before we spend another week on it.
Every web app on this page is running on Harbor right now.

Build out what works
The ones people come back to get the full treatment: a native iPhone and iPad version, App Store pricing, and a proper launch.
Any War began on Harbor. Dragon Hoard, Salt & Powder and Pixel Polyglot are next.

Keep it running
Harbor agents do the routine work on a schedule: nightly syncs, daily review digests, reminders. A small team can run a large portfolio.
Our own scheduled jobs run on AgentCron, an app we built on Harbor.
For companies
Put Harbor to work inside your business.
The tools your teams keep in spreadsheets, the reports someone builds by hand every Friday, the follow-ups nobody owns. We run paid pilots: we sit with your people, build the first apps and agents with them on Harbor, and leave them able to build the next ones themselves.
- A fixed-scope pilot with a monthly fee, not an open-ended contract
- Apps and agents your team owns, with the source to keep
- Senior product and engineering judgement, from people who ship
The Lab
Have an idea, or something half-built?
Build it with us. In the Lab, the people who do the work own a written-down share of what they build, worked out from what everyone puts in rather than negotiated. Prototypes start on Harbor, like everything else here.
Contact
Tell us what you want built.
A Harbor pilot for your company, an app of your own, or a question about one of ours. We reply within one business day.
