Helping your team build with

Building ambitious applications is an expensive journey. We help you reduce costs, build solid foundations and level up your team in the process.

We had a Ember Mapbox project that effective ember executed flawlessly, from responsive css to elegant javascript. Their time management and communication skills are unmatched and made it a pleasant experience for all.

Consulting Services

Custom App Audits

We will take a fresh look at your Ember.js application, determine architectural flaws and put together an actionable prioritized plan for improving your application's maintainability and future development with up to date software development best practices.

Team Upleveling

Letting a development team with potential find their way in a huge ecosystem and learning an all encompassing framework to solve problems thoroughly is a costly endeavor. We will coach your team to get up to speed quickly, look at challenges in a structured way and level them up to solve problems efficiently on their own.

Custom Feature Development

We get together and design and execute a high-fidelity solution to your most challenging problems. Your team will be thoroughly kept in the loop during development and onboarded on how the solution was integrated in your codebase and how similar concepts can be applied to your day-to-day activities in the future.

Hands-on Architecture Direction

Does your business need ongoing Ember.js-guidance, support in application architecture, decision-making support and team mentoring? This monthly service allows you to receive top-notch guidance quickly without hiring a lead frontend architect in-house.

Staging Deploys with ember-cli-deploy

When deploying your Ember.js applications with ember-cli-deploy, working with staging environments can be unintuitive. To do this cleanly you should not think of staging as an environment but in terms of a deploy-target you deploy your application to with a customized configuration. This post shows you how to do this properly.

React Hooks and Ember.js

This follow-up on the comparison between component patterns in React and Ember.js discusses the concept of React Hooks and if the same concept can be applied to Ember.js when creating clean component abstractions.

React Component Patterns in Ember.js

Recently I came across a blog post that discusses several React Component Patterns. In this post, I want to explore if and how these component patterns can be applied to Ember.js and also how Ember.js compares to React when using those patterns.

Constructing robust Ember.js UIs with Statecharts

Ambitious applications are full of complex user flows whose implementation effort is often hard to estimate. The reason for this often lies in the hidden complexity of parts of flows that are only rudimentary contrived by the people that came up with them. Statecharts are a tool that has been used since the 1980s to model complex reactive systems successfully and can help designers and developers drive construction and implementation of robust application flows collectively.

We open source

We believe in open source and try to give back as much as possible. We maintain multiple Ember.js addons ourselves. Here are some highlights:


ember-statecharts provides an easy way to use the popular xState statechart library in Ember.js applications. This is especially useful when modeling and implementing complex user interaction behavior. Statecharts can also be used as a powerful collaborative tool to discuss complex application behavior with non-technical stakeholders and surface hidden requirements that otherwise would be forgotten in the software planning phase.

  • Model behavior explicitly

    Instead of relying on implicit states and complex conditional logic you model your behavior as a set of explicit states that handle events.

  • Build robust UIs

    Because behavior is only executed when a given state understands an event it is impossible to trigger invalid application behavior.

  • Visual Documentation

    Statecharts can be visualized and can be used as a way to discuss application behavior with non-technical stakeholders. A visual representation is also a great way to document how things work and makes it easy to dive into complex behavior implemented by other developers.



ember-showcase is an Ember.js addon that provides developers with primitives to build their own interactive demo components.

  • Interactive documentation made easy

    With component driven design systems it gets even more important to document components so that other developers have an easier time to use them. ember-showcase provides all the necessary primitives like snippets and code-samples for you so it is very easy to build your own custom code example components on top of it.

  • Super flexible

    ember-showcase doesn't come with styling out of the box so it doesn't get in your way when you want to customize its looks. All the functionality for interactive documentation is there though. You just need to assemble it together in a presentational layer that fits your brand.
