ProductLair vs Sellfy: Which Is Better in 2026?

ProductLair helps people research dropshipping products and prepare a Shopify launch. It brings product details, product scores, TikTok advertising engagement data and profit calculations together, so sellers can compare ideas before deciding what to test. The product is built for people starting a dropshipping store and for existing sellers looking at their next product.

Product research

Research starts with the product itself. ProductLair collects product details and scoring alongside advertising engagement data. A seller can review these different inputs together while comparing product ideas. Profit calculations provide another part of that review: the relationship between product costs, the selling price and the resulting margin. These features support a decision about what to test and how to price it.

Preparing a launch

The Launch plan adds material for taking an idea into a Shopify store. It includes Shopify product copy, ad copy and a four-week launch plan. This connects the research stage with the work needed to introduce the product. The Sell plan adds earlier product access, more advertising variants and Shopify CSV export. Sellers can choose the plan that matches how much research and launch material they need.

Pricing

ProductLair has three paid plans, each with a one-time payment. Research costs $49 and covers product research, product scoring, TikTok ad engagement data and profit calculations. Launch costs $99 and adds Shopify product copy, ad copy and the four-week launch plan. Sell costs $199 and adds earlier product access, more ad variants and Shopify CSV export. The paid product uses one-time payments rather than monthly subscriptions.

Public tools and resources

ProductLair also publishes research pages and free browser tools. The free profit calculator works without signup. Users can enter product cost, shipping cost, selling price, upsells and sales volume to review revenue, gross profit and margin. The calculations update as the inputs change. Other public resources cover product ideas, advertising return, shipping and supplier options.

A practical way to use ProductLair

A seller can begin by comparing product ideas, checking the available product details and reviewing the scoring and TikTok advertising engagement data. The next step is to examine the price and cost assumptions with the profit calculations. Sellers who need launch material can use the higher plans for Shopify copy, advertising copy and a launch plan. The research and preparation features are available through the website, with public tools for people who want to explore a calculation before buying a paid plan.
