SNN Systems

SNN Systems is an independent software studio.

It builds native developer tools for macOS and Windows, and web software. Two products, written and maintained by one engineer.

What the studio makes

Both are listed against the same five headings, because the useful difference between them is in the values, not in the pitch.

Chwilio

A native SQLite editor for macOS and Windows.

Chwilio exists because desktop SQLite clients refuse to load your own extensions. It loads them, .dylib on macOS and .dll on Windows, and runs an architecture check and a sandboxed preflight first so nothing reaches your database until it passes. Edits stage as a change set you can read as SQL before it commits, and the interface is written in AppKit and WinUI rather than wrapped in a browser.

Heedpost

Feedback boards, a public roadmap, and a changelog, on your own domain.

Customers post requests and vote on each other’s, and duplicates get flagged while someone is still typing. There is no second list to keep up to date, because the roadmap is those same posts grouped by what you decided. When a request ships, everyone who asked for it gets one email, and the changelog entry links back to the requests it closed.
