Maintenance and support stay flat unless you change them.","The maintenance share is an OceanLab planning assumption with no primary source behind it. Your own bills are the best input for hosting and services."],"sources":[],"faq":[{"question":"What counts as maintenance?","answer":"Bug fixes, dependency and security updates, keeping up with operating system and browser changes, and small improvements. New features are usually budgeted separately."},{"question":"Why is maintenance a share of the build cost?","answer":"A bigger codebase has more to keep up to date. It is a planning shortcut, not a rule; replace it with a fixed budget if you have one by setting the share to match."},{"question":"What rate does support use?","answer":"OceanLab's engineering rate of $50 an hour by default. Change it to your own team's cost or a quote."},{"question":"Is anything I enter sent anywhere?","answer":"No. The tool runs in your browser and there is no sign-up.
