Storeleads maintains a large multi-platform index that it refreshes on its own schedule — excellent for breadth, for firmographic segmentation and for tracking when apps are installed or removed.
Undercart goes deep on each of the 1M+ Shopify stores it tracks. A profile shows the actual ads the store runs on Meta, Google and TikTok; the marketing emails it sends, with their cadence and the discount codes inside; a revenue estimate, annual first, with a confidence score and a “Why this number?” breakdown; its best sellers, price history, discounts and product reviews; the apps it runs, including apps added and removed over time; its social following; and its traffic rank, trend and top markets. Any profile can be refreshed on demand. The trade-off is scope: this depth is only built for Shopify.
Want to see it on a real store first? The free Shopify revenue checkershows any tracked store’s estimated annual revenue range, theme and apps without an account.
Storeleads is a multi-platform ecommerce database (13.8M active stores across 413 platforms) built for list building and CRM enrichment. Undercart is Shopify-only: it tracks 1M+ Shopify stores and goes deep on each — the ads a store runs on Meta, Google and TikTok, the marketing emails it sends, a revenue estimate with a confidence score, its best sellers, discounts and product reviews, the app stack and its social following — queryable from a REST API and an MCP server for AI agents. Storeleads wins on breadth; Undercart wins on Shopify depth.
Yes. Undercart is free for 25 store lookups a month, and $29/month for unlimited stores with CSV export of 3,000 rows a month; API and MCP access work on every plan. Storeleads starts at $75/month (Premium: 2 platforms, 2,000 searches, no export or API); CSV export and API access start on Pro at $250/month, and every platform on Elite at $450/month. What the extra money buys on Storeleads is breadth across platforms and its app install/uninstall history.
Yes. Storeleads reports 13.8 million active stores across 413 ecommerce platforms, about 3.1 million of them on Shopify. Undercart is Shopify-only and tracks 1M+ Shopify stores. If you need WooCommerce, BigCommerce, Magento or other platforms, Storeleads has broader coverage.
Both publish estimates, and neither can see a store's real sales. Undercart shows an annual figure first (monthly second) with a confidence score and a “why this number” breakdown, and its free revenue checker shows any tracked store's range with no account. Storeleads shows an estimated sales figure per store.
Undercart has a REST API and a hosted MCP server (OAuth or API key) on every plan, so an agent in Claude or another MCP client can search stores, read profiles, pull a store's ads and its marketing emails directly. Storeleads also runs a hosted MCP server, available to customers with API access (Pro, $250/month, and up).
Use Undercart if you sell to Shopify merchants and want ads, marketing emails, confidence-scored revenue, best sellers and discounts you can pull from an API or an agent. Use Storeleads if you need the largest cross-platform store database, detailed app install/uninstall history, and CRM enrichment for list building.
Undercart gives you 25 free Shopify lookups — no card, no demo call. See the depth for yourself.
