Why does a tool show no price?

Because that vendor does not publish one. When pricing is quote-only, the page says so instead of inventing a number or repeating a figure from elsewhere.

We treat that as information rather than a gap. "You will have to talk to sales, and they will not tell you the price up front" is a genuine difference between two tools, and often a decisive one for a small team. Where a vendor publishes named tiers without prices, we list the tiers and say the prices are not disclosed.

The same applies to usage-based pricing that cannot be reduced to one number. Rather than force it into a monthly figure that would be wrong for most readers, the page shows the real rate and explains what drives the bill.
