Use cases

What it costs to build it, at your volume

Picking a stack for something new? Each page prices one job across the vendors in the Stackcut catalog at real volumes, says which free tiers are really free, and shows the question to ask your agent. The same data answers choose_stack on the MCP server.

Modeled, not measured. Savings use public prices and planning assumptions: the bill you stop paying, minus the new tool, your upkeep time and your setup time at $50/hour, over the first 12 months. Results marked Tested by Stackcut are Stackcut's own test, not a customer. Every price links the page it came from.
