A blank MRR means the tool publishes a price but no revenue. Absence is information: the tools that show revenue are a minority of the market, which is exactly why the ones that do are worth indexing.

How to read this page
- Entry price is the cheapest monthly tier with a public price — not the tier most buyers end up on.
- MRR is the most recent recurring-revenue figure the tool published; the trail above shows every figure it published, with the date. A tool that only reports total monthly revenue (which can include one-time payments) is shown separately and is not part of the MRR comparisons.
- Tiers counts monthly plans found on the pricing page. A tool with one tier has one price to defend.
- If the price column says no monthly price recorded, the tool quotes instead of publishing — above $199 that is the norm in this market, not a gap in the data.
