Kretes is built on top of [Snowpack](https://www.snowpack.dev/), a modern build tool for **faster** web development.  In development, client-side assets are **compiled on-demand** when requested. **Hot Reload** is instant and independent of the project size (so called O(1) bundling).


Develop Faster

Kretes uses the [Nix package manager](https://nixos.org/) for dependency management. Your project setup can be easily transferred between different machines, whether **sharing it with coworkers**, or when switching **from development to production environment**.


Share Project Setup

Kretes uses only **one programming language**: TypeScript, for the entire application (front-end to back-end). By using TypeScript across the board, there is just **one ecosystem**, **one tooling** and **one way of hiring** for software teams to learn and integrate.


TypeScript Everywhere

Kretes comes with a (eventually large) library of useful modules which are **developed in a coherent way**. It is an **integrated solution** that optimizes for programmers productivity by **reducing choices** and incorporating community conventions.

Kretes helps us kick start projects quickly and brings us tools we really like.  We build a lot of prototypes on daily basis and we see great value in integrated,  battery-included solutions.

I really do enjoy coding. But as CPO of a growing scale-up, well, I am not really  supposed to spend that much time hacking. And not being a JavaScript fan, spending  any amount of time in boilerplate and webpack rituals on a small JS project is  frustrating. Which is why I enjoy Kretes. No nonsense. It hits a nice sweet-spot  for doing a quick TypeScript POC, and it makes it easy to go back to a project a  couple of weeks later. Even when I didn't actually write down WTH I was actually  trying to achieve. And it still feels solid. There's a nice Rails vibe to it I  haven't yet met in the JS world.


Ori Pekelman

I love how Kretes allows to quickly prototype full-stack web apps in TypeScript.  At Xfaang we constantly build and play with different app ideas for our clients  - rapid software development is an important factor. Kretes makes the development  not only easier, but also more enjoyable. It’s a great tool for software  companies to gain a competitive edge.


Piotr Zientara

Kretes brings back the joy of programming by setting up reasonable defaults and  aims to keep you productive. It also makes your app easier to test by taking a  more functional approach. You'll like it!


Emil Ajdyna

As an AI company, we build a lot of prototype apps on top of our algorithmic engines  applied to this or that use case. While not being our core business, building sleak  apps quickly is actually a critical component of what we do. Kretes helps a lot  achieving all that, without nonsense, and it allows the team to be efficient and worriless  on the app side, while focusing on our core, AI problem solving.


Julien Muresianu

JavaScript landscape is fragmented. As a software house we are constantly looking for ways  to reduce the time spent on figuring out how to connect and combine different tools and  frameworks - and Kretes does this very well.


Michał Olczak

Kretes feels extremely fast in the development cycle. It is easy and simple to bootstrap  a new project. It provides a nice structure with convenient defaults. I find it especially  useful for junior developers, they can be much more productive from the get-go, than  wasting time to setup the project on their own. Kretes looks promising.


Benoit Molenda

Software Consultant

At Miquido, we do not limit ourselves to specific solutions. While monitoring the latest  technologies and solutions, we could not be indifferent to Kretes. This framework allows  for a very fast implementation of MVP, which contributes to the improvement of the quality  of delivered applications.
