A Similarweb API alternative for search traffic, without a sales call
You want traffic estimates for a list of websites (competitors, leads, partners) inside a script, a spreadsheet, n8n or an AI agent, and the Similarweb API is the first name you find. Here is how it is sold, what PlainRows returns instead, and when each one fits.
How the Similarweb API is sold
From similarweb.com/corp/pricing on 2026-10-18:
- No price is published: the page asks you to talk to sales and to select "API" in the form.
- The API is part of customized packages for businesses, or can be bought as a standalone product without a platform subscription.
What PlainRows returns and charges
No plan and no sales call. Website Traffic Checker (Domain SEO Overview) runs on Apify: the free Apify plan is enough to test it, the Starter plan ($19 per month with $19 of usage included, apify.com/pricing) removes the free-plan limits.
| Data | Tool | Price (Starter plan) |
|---|---|---|
| Estimated monthly Google organic traffic, number of ranking keywords, ranking position distribution, paid search traffic and keywords, for a list of domains in 94 countries | Website Traffic Checker | $0.004 per domain with data |
| The keywords that bring each site the most traffic (position, URL, volume, CPC, difficulty), optional | Website Traffic Checker | $0.002 per keyword |
Example: 1,000 domains with data cost $4.00. From October 25, 2026, each run also costs $0.012 to start and a domain with data costs $0.005 on the Starter plan. Domains with no data, duplicates and input mistakes are free, and a run never spends more than the maximum cost you set.
When Similarweb is the better choice
- You need total website visits, or direct, referral, social or app traffic: PlainRows only estimates traffic from Google search results (organic and ads).
- You need audience data (demographics, engagement, device split) or a contract with support and a data feed.
When PlainRows is the better choice
- You care about SEO: how much traffic a site gets from Google, from how many keywords, and which keywords bring it.
- You check a list now and then and want a price per domain, with results in n8n, Make, Zapier, Google Sheets or an AI agent (MCP).
