The bottom line

Useful for competitor SEO and Google Ads research; verify API limits and data fit before building around it.

SpyFu is a hosted SEO and PPC competitor-research platform with a documented API for integrations and exports. Its strongest fit is researching competitors’ Google Ads, keywords and ad history; the API credits on Basic and Pro + AI make small integrations possible without a separate API-only plan.

We’d treat it as a research data source, not a system of record. There is no free plan, and the vendor doesn’t publish API rate limits or SDK details on its homepage. Reddit users praise its Google Ads research but also question keyword coverage and the accuracy of estimated spend.

01What SpyFu is, technically

SpyFu is a hosted, web-based SEO and PPC competitor-research service, not a library, CLI or self-hosted server. It gives marketers and developers a way to query competitor keywords, Google Ads history, rankings and backlinks, then export research or connect the data to other tools through its API.

In a marketing stack, SpyFu sits between search-engine data and the systems that use competitive intelligence: reporting dashboards, campaign planning workflows and internal research tools. Its site also includes a site-audit workflow that scans for technical and on-page issues, generates AI fixes for review, and lets users publish approved changes. Performance tracking covers keyword rankings, ad performance and competitive positioning. The vendor says its research data is refreshed every 15 seconds and promotes 18+ years of historical data. Those are vendor claims about its data service, not a guarantee that every estimate matches a competitor’s actual account or spend.

02SpyFu API, SDKs and docs

SpyFu’s homepage describes a documented API with endpoints for custom integrations and automated exports. That makes the API the main developer integration surface; the web app is the other way to research and download competitor data. The homepage does not name an API protocol, SDK, programming language, CLI, webhook or plugin, so confirm SDK and protocol support in SpyFu’s API documentation before choosing a client or planning deployment.

API credits are included with Basic and Pro + AI: $40 on Basic and $100 on Pro + AI. The Team / Agency plan does not list an included API-credit amount. The pricing page also does not state request limits, credit conversion, endpoint-specific costs or what happens when credits run out. Before wiring the API into scheduled jobs, confirm those terms, authentication requirements, error behavior and export formats with SpyFu. The site positions ChatGPT integration as a way to use SpyFu data for marketing research and actions, but does not describe it as a general-purpose developer SDK.

03SpyFu pricing for developers

SpyFu has no free plan, and the pricing page does not list a free trial. Basic costs $39 per month or $29 per month on an annual plan billed annually. It includes $40 in API credits, one user, 10,000 search results and data exports, and one live-site tracking project. Pro + AI costs $119 monthly, with the first monthly month listed at $59, or $89 per month billed annually; it includes $100 in API credits and one user. Team / Agency costs $249 monthly or $187 per month billed annually, with five users and no stated API-credit amount.

The bill can grow with seats: additional users cost $15 per month on Basic and $30 per month on Pro + AI or Team / Agency. Plans also cap crawl pages, AI fixes and tracked keyword rankings, while Basic caps search results and exports. The vendor does not publish overage rates or API-credit top-up pricing in the plan details, so confirm what happens at each limit before automating production workloads.

04SpyFu: open source, self-hosting and lock-in

SpyFu is a hosted service, not a self-hosted deployment. The vendor does not publish an open-source license or a self-hosting option, so treat the application and its data service as closed and vendor-operated. That means you depend on SpyFu for access to its research interface, API and underlying competitive data.

The product supports data exports, and its API is intended for automated exports, which can help you retain selected research outside the service. The vendor does not publish export-format or data-retention guarantees in its homepage text. Before relying on SpyFu as a long-term data source, ask whether exports cover the records and history your workflows need, how often you can retrieve them, and what happens to stored data when an account closes. Your own integration code should keep normalized copies of the outputs it depends on; that reduces dependence on the API for previously collected data, but cannot replace SpyFu’s ongoing data collection.

05SpyFu in production

Before making SpyFu a production dependency, confirm API rate limits, credit accounting, authentication, error responses, data retention and support escalation. The vendor promotes live SEO and PPC intelligence refreshed every 15 seconds, and says performance tracking updates every 15 minutes. Those refresh claims do not establish API availability or an uptime commitment. Security and compliance details should also be checked with the vendor before sending account or customer data through an integration.

Reddit reports are mixed on data quality. One r/SEO poster said the keyword research looked “incorrect and lame,” while other commenters value SpyFu for competitor Google Ads research. A Reddit discussion about estimated ad spend describes a large gap between a user’s actual Google Ads billing and SpyFu’s estimate; the SpyFu founder said spend estimates use observed keywords, cost-per-click and estimated impressions. Treat competitor spend and traffic as directional estimates, not financial records. Validate high-impact decisions against your own campaign data and other sources.
