Midday: The Open-Source Business OS for Freelancers and Solo Entrepreneurs
Discover Midday, an open-source, all-in-one business management tool for freelancers and solo entrepreneurs. It integrates time tracking, invoice management, a magic inbox, and a financial assistant to help you run your business more efficiently.

For freelancers, consultants, and solo entrepreneurs, juggling different tools for managing time, projects, finances, and files is a significant drain on energy and focus. An open-source project named Midday aims to solve this pain point by becoming a unified, intelligent command center for business operations, allowing independent professionals to "run your business smarter."
Midday is an all-in-one business management tool designed specifically for solopreneurs. It integrates core functions like time tracking, invoicing (coming soon), intelligent financial matching, and secure file storage into a single, well-designed system, aiming to replace a cluttered toolkit and boost operational efficiency.
Core Feature Highlights
- Time Tracking: Built-in, live project time tracking helps users clearly understand where their time is going and improves productivity.
- Magic Inbox: Automatically identifies incoming invoices or receipts and matches them to the correct transactions, dramatically simplifying the complexity of financial organization.
- Assistant: Provides tailored insights into financial situations, helping users understand spending patterns, cut costs, and quickly find necessary documents.

A Modern Technology Architecture
Behind Midday is a thoroughly modern tech stack. It uses Bun as its runtime, is built with Next.js, React, and TypeScript, and is deeply integrated with Supabase as its Backend-as-a-Service (BaaS). Furthermore, the project plans to support desktop and mobile apps via Tauri and Expo, creating a truly cross-platform experience. Its backend leverages a wide array of advanced third-party services like Plaid, Mistral, and Gemini to build a powerful automation and intelligence engine.
