Frontend

⚡️ Next.js / React

We are using Next.js by Vercel to power our frontend. You don't need to take care of bundling and get server-side rendering for free.

🌊 Tailwind CSS

Tailwind CSS is a highly customizable, low-level CSS framework that gives you all of the building blocks you need to build bespoke designs without any annoying opinionated styles you have to fight to override.

• Fastest way to write styles (no commas & quotes)

• Styles will not bloat your HTML/JSX as inline styles does it

• Powerful IntelliSense Plugin for autocomplete

⛓ urql

urql is a lightweight GraphQL client for React made by Formidable. It is a great alternative of apollo-client . We use it to fetch data from the GraphQL backend.

• Lightweight and well maintained

⚙️ GraphQL Code Generator

We use GraphQL Code Generator to generate Typescript typings & urql hooks from your GraphQL backend. There are plugins for other clients, Java, Reason & .NET that will generate typings for those.

📊 recharts

We are building our charts using recharts. It's built on top D3 and allows you to compose charts using React components.

• Great documentation

• Easy to customize

🐠 Feedback Fish

feedback.fish allows us to gather feedback using a simple widget on the dashboard. It's a service made by Max Stoiber, Timo Lins, Laurids Kern and me. This helps us receive the feedback via email or can view it in the powerful dashboard.

Backend

🌳 Node.js

All backend parts are written in Typescript using Node.JS. We're using PM2 as process management tool. It automatically restarts services if they fail.

📜 BullMQ

BullMQ is the fastest, most reliable, Redis-based distributed queue for Node. It allows us to distribute the workloads to multiple workers. Long running concurrent jobs are also distributed via BullMQ.

💾 PostgreSQL + TimescaleDB

We are using PostgreSQL to store all data. The Timescale extension allows us to efficiently query and aggregate time-series data. We can archive 10-100x faster queries than using native PostgreSQL, InfluxDB or MongoDB.

🧰 TypeORM

TypeORM is an ORM that helps us to write & query data. You can simply create a new table by adding annotations to a Typescript class. It works perfectly together with TypeGraphQL.

• Database migrations are amazing

🎡 TypeGraphQL

We use TypeGraphQL to create the GraphQL schema, types and resolvers only with TypeScript, using classes and decorators!

• Works perfectly with TypeORM

Analytics Backend

🤖 Cloudflare Workers

We heavily rely on Cloudflare Workers. They are simple micro-services written in Typescript.

• Your code runs within milliseconds no matter where you are

🔑 Cloudflare KV

Cloudflare KV is a distributed key-value storage that is used to provide the CF workers relevant information for each request. We also use it to store the pinned version for A/B testing.
