Stackcommander builds QueryMax, a native macOS SQL client, and TCFrameLock, a Broadcast WAV stamp from LTC — plus focused iOS apps for currency conversion, profit forecasting, and SVG files.
Each product has its own page, privacy policy, and support URL.
Native macOS SQL client
A native SwiftUI SQL editor for Mac. SQLite is free. MySQL and MariaDB unlock for $19.99, or try one read-only schema without buying. Schema diagrams, dashboards, password SSH tunnels, and optional AI help. Data stays on your Mac.
SQLite free · MySQL/MariaDB $19.99
Broadcast BWF stamp from LTC
Drop a multitrack session where one track is Linear Timecode. TCFrameLock decodes that clock, back-calculates the SMPTE address at sample 0, and writes new Broadcast WAV files with the starting frame already set. Mix audio is copied, not re-encoded.
macOS 14 or later · local files only
iOS travel converter with a home currency and three favorites. Type one amount and see all three conversions at once, plus reverse. 140+ currencies, live rates, offline cache, units, and home screen widgets.

SQLite is free. MySQL and MariaDB unlock for $19.99. Without the unlock you can add one read-only MySQL or MariaDB schema. Built-in SSH tunnels use a password (not a key or certificate). SSL/TLS to the database is supported. QueryMax connects from your Mac; we never see your traffic.
No. It is a desktop SQL client. Passwords go in macOS Keychain. Optional AI features may send table and column names (not row data) to a provider you pick, such as Gemini or Claude.
TCFrameLock is a Mac app for post and broadcast. Drop a session that includes an LTC track. It decodes that clock, works out the SMPTE address at sample 0, and writes new Broadcast WAV files with the starting frame already in the bext Time Reference. The mix is copied, not re-encoded.
QueryMax and TCFrameLock for Mac, plus Currency Converter + Widgets, Profit Forecast, and SVG Viewer on iOS. The site also has a free JSON visualizer and comparer.
No. QueryMax is a free SQLite IDE; MySQL and MariaDB are a one-time $19.99 unlock. TCFrameLock is a macOS Broadcast WAV utility. Currency Converter, Profit Forecast, and SVG Viewer are typically $1 lifetime on iOS.
Stackcommander is a small independent studio that ships native Apple software. The flagship Mac app is QueryMax, a SQL client and IDE for MySQL, MariaDB, and SQLite. TCFrameLock is the second Mac product: it reads Linear Timecode from a multitrack session and writes Broadcast WAV files with the starting frame already set.
The iOS lineup is intentionally small: a travel currency converter with widgets, a profit forecast for digital products, and an SVG viewer that can export icon sets. We prefer one-time pricing, local data, and pages that say what the software actually does.
