About
Build or Bill answers one question for technical teams: is this subscription worth paying for, or is the useful part of it something you should own?
Search any of 1,222 assessed products and you get:
A verdict — build it, build the part you actually use, keep paying, or self-host it.
The annual bill, read verbatim off the vendor's own pricing page.
Open-source prior art — 1,826 existing projects that already do the core job, linked.
A first-year calculator for one product or your whole stack: your seats, your hourly rate, the build and upkeep hours.
Copyable replacement prompts scoped to the tool you're replacing.
Every row carries its receipts: whether the price was checked, how many sources were cited, whether a working open-source build exists, whether repeat runs agreed. Rows with thin evidence say Thin. The score is arithmetic over recorded facts, printed term by term on every product page - no judgement call moves the number, so it recomputes identically every time.
Where no verdict wins a majority across runs, the product isn't published at all.
The full methodology is public. Nothing is labelled verified that hasn't been tested.
