RetentionLens vs ProfitWell: Why Free Metrics Aren’t Always Free

ProfitWell Metrics (now part of Paddle) is famous for one thing: free subscription analytics. That is a real and generous offer. But free always has a shape, and understanding it is the difference between a smart choice and a surprise later. Here is how RetentionLens compares to ProfitWell, and what the free tier is actually built to do.

What ProfitWell does well

ProfitWell Metrics gives you accurate MRR, churn, LTV, and growth charts at no cost, with connectors to Stripe and other billing systems. For a free product the data quality is strong, and for early teams it is an easy way to get real subscription metrics without a budget line.

The trade-off behind free

ProfitWell is owned by Paddle, a merchant-of-record billing company. The free metrics product is part of a wider ecosystem whose commercial center of gravity is Paddle’s billing and the paid retention and pricing products around it. That is not a criticism — it is the business model. But it means the free tool is a front door, and the roadmap and integrations naturally favor that ecosystem over a neutral, standalone position.

RetentionLens is a standalone, paid tool with one job: churn and retention on Stripe. You are the customer, not the lead. The trade-off is reversed — you pay, and in return the product’s only incentive is to answer your retention questions well.

Quick comparison

How to choose

• Choose ProfitWell Metrics if you want free broad subscription metrics and are comfortable inside Paddle’s ecosystem.
• Choose RetentionLens if you want a neutral, focused churn-and-retention tool on Stripe and prefer paying for it over being the funnel.
• If you already use or plan to use Paddle as your merchant of record, ProfitWell is a natural complement; if you are firmly on Stripe and want depth on retention, RetentionLens is the tighter fit.
