Bread-and-Butter Application

Dev & startup terminologies | Noun

an app which puts food on the table, unlike millennials who still live with their parents. Bread-and-Butter application informally designates essential software without which a business cannot function or would be significantly impacted if it went down. This type of software is usually given the most priority in terms of maintenance and security and backups are used to ensure nothing gets lost. Redundant systems are put in place to keep them up and running at all times.


“Inventory is our bread-and-butter application” “I was told this is a gluten-free company during the hiring interview. You will hear from my lawyer.”
