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.
Vault: Offers a secure, centralized storage location for important files like contracts and agreements, making them easily accessible at any time.
Seamless Export: Effortlessly packages financial data into CSV files, simplifying the process of working with an accountant.

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.

Open Source License Information

The project is licensed under AGPL-3.0, intended primarily for non-commercial use. Any commercial use or deployments that require a setup fee will need to contact the development team for a commercial license.

For any independent professional looking to streamline their workflow, or for developers interested in how to build a complex SaaS application with a modern stack, Midday is an excellent open-source project to watch.
