Storeleads maintains a large index that it refreshes on its own schedule — excellent for breadth and for tracking when apps are added or removed over time.
Undercart re-crawls Shopify storefronts nightly and enriches each one end to end: it reads the live storefront and /products.json, probes inventory, detects the app stack (including GTM-loaded tools), aggregates ad presence, infers the Shopify plan, and resolves a composite revenue estimate. Stores that grow or churn get re-scored, so lists do not go stale. The trade-off is scope: this depth is only run against Shopify.
Storeleads is a multi-platform ecommerce database covering 13M+ stores across 400+ platforms, built for large-scale list building. Undercart is Shopify-only and runs a live enrichment pipeline that produces per-store revenue estimates with confidence scores, ad-presence data, and an API plus MCP endpoint for agents. Storeleads wins on breadth; Undercart wins on Shopify depth and automation.
Yes, at every tier. Undercart is free for 25 store lookups a month, $29/month for 100 lookups, and $99/month for unlimited lookups — with API access on every paid plan. Storeleads starts around $75/month, and CSV export plus API access require its Pro tier at around $250/month. What that extra money buys on Storeleads is breadth: 13M+ stores across 400+ platforms versus Undercart's Shopify-only coverage.
Yes. Storeleads indexes 13M+ stores across 400+ ecommerce platforms. Undercart is Shopify-only and tracks around 2 million Shopify stores. If you need Magento, WooCommerce, BigCommerce and others, Storeleads has broader coverage.
Both estimate revenue. Undercart computes a composite estimate from catalog, pricing, ad spend, tech stack and social signals, weights it by confidence, benchmarks it against a truth set, and runs an LLM plausibility check on very large numbers. Storeleads also publishes sales estimates but exposes less about per-store confidence.
Undercart exposes both a REST API and an MCP endpoint, so agents can call it directly with a single API key. Storeleads offers a REST API on its Pro tier but does not currently publish an MCP interface.
Use Undercart if you sell to Shopify merchants and want live, confidence-scored revenue and ad data you can pull from an API or agent. Use Storeleads if you need the largest cross-platform store database and detailed app install/uninstall history for list building.
Undercart gives you 25 free Shopify lookups — no card, no demo call. See the depth for yourself.
