Today we’re launching Nut.new as an easy to use, reliable AI tool for building working full stack apps. When you ask Nut for an app, it discusses the requirements with you and develops a plan: how the pages will be laid out, the different features, database specification, APIs the app will use, tests that are needed, and so on.
Nut builds a non-functional mockup first, then implements working versions of the app’s components, then writes tests for those components and fixes the problems they surface using Replay’s time travel debugger. All this is done in parallel, with workers merging changes into the app only when all tests pass, as professional engineers would do.
When development finishes you’ll have a working app, produced with barely any effort on your part and deployable with a couple clicks. We got tired of vibe coding tools that expect you to QA all their broken code. Nut still writes broken code but catches and fixes its problems, taking the human almost entirely out of the development loop. The resulting app might still have changes you’ll want to make, but if you ask Nut it will update the app and write tests to make sure its changes worked.
Examples
Nut is best at building apps that manage a database and have straightforward UIs to operate on that database and access external services. Here are examples of apps we’ve built:
- Spendypants (App), an expense tracking app for couples to make getting a handle on finances fun.
- A basic customer support CRM for managing customer tickets with priority-based organization and status tracking.
- A smalltalk generator (App) with a tinder-like swiping UI for showing conversation suggestions.
Nut can’t build everything, but it’s designed for a wide range of apps that manage and automate internal business processes, help with personal tasks, and provide bespoke services for your family or community.
Guaranteed Reliability
When you build with Nut we want you to know you’ll get what you’re looking for, and know up front how much it will cost. This is what you’d expect when paying an engineer to build your app. With our launch we’re also opening up a waitlist for a higher tier of service from Nut that guarantees reliability.
When you plan an app, Nut will rate its confidence that it can implement each of the app’s features, and give you a price for the features it is confident in and an estimated implementation time. It will develop the app, and if it fails or takes too long you keep everything it built, entirely for free.
This is possible because Nut is great at debugging. It’s straightforward to break down an app into features and throw AIs at them, but without effective debugging it often takes dozens or hundreds of attempts to finish a feature instead of spinning in a circle. Nut gets these features done within a few attempts, usually on the first one.
We want Nut to be a great development partner for you and help you through the process and get the app you’re looking for. Try Nut today and let us know what you think and/or join our guaranteed reliability waitlist for access as soon as it’s available.
