Budgeting app/software
Based on your question about budgeting apps with plugin capabilities, here's my tailored advice:
YNAB (You Need A Budget): While YNAB doesn't have a traditional plugin marketplace, it offers an API that allows for third-party integrations and custom solutions. This can be used to create custom views or sync data with other apps.
Tiller: Tiller uses Google Sheets or Excel, which inherently allows for customization through add-ons and scripts. You can create custom templates and views using spreadsheet functions and Google Apps Script.
GnuCash: This open-source accounting software supports plugins, allowing developers to extend its functionality. While it's more complex than typical budgeting apps, it offers extensive customization options.
Personal Capital: While not strictly a budgeting app, Personal Capital offers an API that developers can use to create custom integrations and views of financial data.
Mint (with limitations): Mint doesn't have an official plugin system, but it does offer some integration capabilities through services like Zapier, which can be used to create custom workflows.
