Introducing SidequestLab

A laboratory that creates value through various side projects. Let us tell you the story of SidequestLab.

Hello! We are SidequestLab.

Today, through this blog, we want to introduce our team and share the projects we're building.

What is SidequestLab?

SidequestLab is "a laboratory that creates value through various side projects."

It doesn't have to be a big project. Our goal is to start from small ideas and deliver real value to users.

Our Projects

We have completed and deployed 8 projects so far. Each project focuses on solving real problems for users.

1. Todo App

A simple and intuitive todo management app. We focused solely on task management without complex features. Built with React and TypeScript, this is SidequestLab's first project.

2. Pomodoro Timer

When you need to focus, nothing beats the Pomodoro technique. Boost your productivity with cycles of 25-minute focus and 5-minute breaks. Try it now

3. N-Bang Calculator

Have you ever had trouble splitting bills after gatherings or dinners? The N-Bang Calculator solves this problem.

  • Multi-round splitting (different participants for each round)
  • Transfer optimization algorithm
  • No app required - use it directly in your browser

Try it now at nbbang.click! This is our first monetization project.

4. SidequestLab Homepage

A real-time collaborative note-taking app. Multiple people can edit simultaneously with instant synchronization powered by Supabase Realtime.

In Progress: BookSalon

A book club platform for reading and discussion. Will feature reading logs, discussion rooms, and schedule management.

Future Plans

We will continue to explore new ideas and quickly build prototypes to validate them.

  • Embracing User Feedback: Your opinions are a great source of strength for us
  • Continuous Improvement: We improve things one step at a time
  • New Challenges: We plan to introduce more side projects

Through this blog, we'll share development stories, project updates, and news from our team.
