Every plan includes a monthly working allowance for your engineer — the bigger the plan, the bigger the budget: Spark 1×, Capsule 2×, Builder 10×, Studio 25×. Your Flight Deck shows how much of the month's allowance you've used as a percentage.
Most owners never touch the ceiling: routine edits and fixes are small. Big builds (whole new sections, lots of iteration) use more.
If you do use it all: nothing goes offline. Your site, address, and data keep running exactly as-is — only the engineer rests until the allowance resets on the 1st. Want more room? Upgrade a tier, or power users can connect their own API key and pay for usage directly.
