I built Mergen to prove that we can have modern, React-based UIs without the heaviness of Electron.

Mergen is a cross-platform SQL client (currently supporting MySQL/Postgres) that uses Wails. This allows it to use the native system webview, resulting in a ~15MB app size and instant startup times compared to DBeaver or TablePlus.

Features for HN crowd:

Local-First: No cloud accounts, fully offline capable.

Secure: Native SSH Tunneling support.

Visuals: Built-in data visualization (charts) from query results.

Code is open source (GPLv3).

Happy to answer technical questions about the Wails implementation!
