Sylvester Keeps Your Brokerage in the Menubar

trysylvester.org Observed source

Editorial interest 79/100 Selection signal · not a rating of the site

A read-only macOS menubar app for monitoring net worth and holdings across linked brokerages.

Landing page captured for the 2026-09-13 issue.

Field notes

Sylvester uses SnapTrade for browser-based authorization, then presents brokerage data in a macOS menubar popover. The page names allocation views by asset, account, or currency, plus day-by-day dividends, trades, and deposits. Its stated privacy boundary is unusually concrete: OAuth2 with PKCE, Keychain storage, direct Mac-to-API communication, and no analytics or crash reporting. Installation targets macOS 14 or later on Apple Silicon and includes a workaround for its ad-hoc signature.
