Show HN: Mergen – A native, local-first SQL client built with Go and Wails
parevo Friday, December 26, 2025
Hello HN,
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).
Repo: https://github.com/parevo/mergen
Happy to answer technical questions about the Wails implementation!
Summary
