Leonidas Jeremy

I'm Leonidas, the person behind QueryDeck. I run a small software studio called Try Hard in Belgium, where I ship native Mac apps for developers and small teams. QueryDeck is my second product after Noticky.

I built QueryDeck because every database client I tried on macOS forced me to pick between three bad options: a slow Electron app that ate 800 MB of RAM, a JVM tool that looked stuck in 2014, or a generic GUI that knew nothing about my project. None of them understood my ORM, my .env, or my Prisma schema.

QueryDeck is built in Swift and AppKit, runs natively on Apple Silicon, and connects to the five databases app developers actually use: PostgreSQL, MySQL, SQLite, MongoDB, and Redis. The CLI companion auto-detects your ORM (Prisma, Drizzle, TypeORM, SQLAlchemy, ActiveRecord, Eloquent) and connects in one command. SQL notebooks let you mix queries, results, and Markdown in one exportable file.

It's closed-source, one-time pricing, no subscription. I make the calls, I sign every release, I answer every support email myself. If you find a bug, I'm the one fixing it.

I'm bootstrapped and solo. There's no team, no investors, no roadmap committee. That's the trade-off you get when you buy from a small studio: less polish in some corners, but real human contact and a product that doesn't pivot away from you.
