Mergen combines the raw performance of **Go** with the fluid interactivity of **React**, delivering an experience that feels native, instant, and incredibly responsive. It's not just a tool; it's a workspace you'll love to inhabit.

## 🥊 Mergen vs. The Rest

Why settle for bloated, expensive tools when you can have perfection?

**The Truth About Electron:**
Most modern database tools are built on Electron, effectively bundling a whole web browser with every app. This eats your RAM, drains your battery, and slows down your workflow.

**Mergen is different.** By using Wails, we leverage the native webview already present on your OS. The result? An app that looks better, runs faster, and respects your hardware. Don't pay for bloat. Choose Mergen.

| **Backend** | [Go (Golang)](https://go.dev) | Unmatched concurrency and speed for handling database connections and I/O. |
| **Frontend** | [React](https://reactjs.org) | The industry standard for building dynamic, responsive user interfaces. |
