PartsBox founder here. I get asked about this sometimes, so I'll answer here: I'm quite happy with open-source solutions appearing in the same problem space. I bought ECDB, but left the open-source software available on GitHub for anyone who wishes to take it further. My software will not be open-source for a number of reasons, most importantly I cannot afford to take on the chores of a project leader/maintainer.... - Source: Hacker News / 11 months ago

Https://stonksfolio.com I started it to track my all my investment accounts in one place and a couple of years ago decided to open it up to the public. Active users are in the hundreds but not growing rapidly. Tried to monetize it with Patreon but only 2 people actually subscribed. It's a fun project to work on, though, and not having paying customers allows me to ignore it until I get the enthusiasm to work on it... - Source: Hacker News / over 2 years ago
