Why build with Hora Kit

Speed and quality —
you don't have to choose.

Hora Kit, the AI development framework we built and publish as open source, runs your tests and security checks automatically. What you get is a system that is fast to build, affordable, and hard to break.

  • Full tests and automated E2E tests

    Every feature tested, down to the screen

    Every feature gets its test cases, and end-to-end tests that replay real screen interactions run automatically. The whole suite runs on every change, so a fix in one place never breaks another.

  • Automated security checks

    Vulnerabilities fixed before production

    Each feature is checked automatically for how it handles input, authentication and information leaks. Anything found is fixed before it ships.

  • Serious systems, affordably

    Real quality at a realistic cost

    AI takes on much of the implementation, testing and verification, which cuts the hours people spend. You get the freedom and quality of custom development at a cost within reach.

Use cases

When this sounds like you,talk to us.

  • Replacing expensive SaaS

    Swap a SaaS whose monthly fees keep growing for a system of your own with only the features you need.

  • Replacing legacy systems

    Even an old system with no surviving specification: we read how it behaves today, turn that into a specification, and rebuild it with tests.

  • Product development

    Build a new service one agreed feature at a time. Reach the market sooner and start improving sooner.

  • Fast internal systems

    Quickly replace work run on spreadsheets and paper with admin screens and workflows that fit how you work.

  • In-house enablement

    We bring a Hora Kit development flow to your team, including how to run specifications, tests and acceptance.

  • Not sure which one fits?

    Tell us about your challenge and we will propose how to approach it.

How we work

You decide. AI moves it forward.

  1. STEP 01

    Consultation

    No need to have your requirements ready. We sort them out together, in conversation.

  2. STEP 02

    Agreeing the specification

    Only what you approve goes into the specification.

  3. STEP 03

    Development and testing

    Each feature is built and passes automated tests and security checks.

  4. STEP 04

    Acceptance and release

    You check it on working screens before it goes to production.

Open source

Hora Kit is open source.
Anyone can use it for free.

Hora Kit is published on GitHub as open source, so anyone can use most of its features free of charge. Try it in-house first, and talk to us when you are ready for full development or to bring it into your team.

See Hora Kit on GitHub
git clone https://github.com/openreachtech/hora-boilerplate.git my-app && cd my-app && npm install
/hora

Clone it and type /hora in Claude Code. It starts by writing the specification.

Message from the President

A new de facto standard for software development.

Jiro Yamamoto, Representative Director of Open Reach Tech Inc.
Representative DirectorJiro Yamamoto山本 次郎 / OpenReachTech Inc.

Software development still faces a hard reality: more than 80% of projects do not go according to plan. One of the biggest reasons is dependence on individuals — whether a project succeeds swings on the skill and experience of the engineers assigned to it.

We have made our development process thoroughly uniform and transparent, standardized our technology stack, and fused AI into it, realizing a next generation of development that combines overwhelming AI-driven speed with high maintainability.

We have no intention of remaining merely a good development company. We press ahead every day with the resolve to create a new standard for the software development industry.

Physical AI

AI that moves the real world
needs a software brain.

Japan builds some of the world's best reducers, motors and sensors, yet lacks the people who write the software that brings them to life. From simulation to compute infrastructure to on-site visits, we take on Physical AI from the software side.

  • Simulation support

    Before a robot moves, we set up environments to train and test it in virtual space.

  • GPU server sourcing and setup

    We help with the compute that training and simulation need, from purchase to setup.

  • Visits to Chinese Physical AI companies

    We arrange trade-show and company visits to see the technology and supply chain first-hand.
