It's a split decision.
Pick SerpApi if your application needs more than Google search, including APIs for maps, shopping, jobs and other data, or you want its listed language integrations and CLI. Pick Serper for a Google-focused integration with prepaid packages and published QPS tiers. SerpApi charges monthly and sets hourly throughput limits; Serper’s packages expire after six months. Both are hosted APIs, so choose based on query scope, billing fit and how their response schemas fit your code.

02Pricing at real usage
SerpApi has a recurring monthly free plan with 250 searches and throughput of 50 per hour. Paid plans start at $25 per month for 1,000 searches; Developer is $75 for 5,000, and Production is $150 for 15,000. Big Data is $275 for 30,000 searches. Each paid plan also lists an hourly throughput limit. Serper’s free allowance is 2,500 queries once, with no credit card required; requests stop when the balance reaches zero. Paid access uses prepaid packages: $50 for 50,000 credits, $375 for 500,000, $1,250 for 2.5 million, or $3,750 for 12.5 million. The listed rates fall from $1 to $0.30 per 1,000 credits as package size grows. Packages are valid for six months. The pricing page lists no monthly Serper plan or overage price, so budget for another prepaid package when credits run out.
03API, SDKs and integration
Both products are hosted APIs; neither is described as a library you embed or a server you deploy. SerpApi returns structured search-engine results and other data, with JSON or Markdown output. Its catalog covers Google and other search engines, as well as maps, shopping, jobs and many additional services. The homepage lists integrations for Ruby, Python, JavaScript, Golang, PHP, Java, Rust, .NET, MCP, Swift, C++ and CLI. Serper focuses on Google search results. Its query types include search, images, news, maps, places, videos, shopping, Scholar, patents and autocomplete. The homepage shows a JSON response example. Serper’s homepage lists no other integrations. SerpApi’s broader catalog may reduce the need to add separate providers when an application needs several data types; Serper’s narrower scope means less API surface to consider for a Google-only feature. Check each API’s response fields against your application’s models before wiring it into production.
04Open source, self-hosting and lock-in
Neither vendor publishes an open-source licence or self-hosting option. Plan to call these as hosted services rather than deploy them inside your own infrastructure. SerpApi returns structured results in JSON or Markdown, with fields such as links, prices, ratings and reviews. Serper’s homepage shows a JSON response with fields including organic results and a knowledge graph. Those response shapes become part of your application’s integration: isolate provider-specific parsing behind an internal interface, and map the fields your product uses into your own schema. Both vendors leave data-export and migration procedures unpublished, so ask about retention, export formats and account closure before committing. Switching providers may require rewriting request parameters and response mapping, especially if your code depends on provider-specific result fields.
Questions people ask
Which is cheaper, SerpApi or Serper?
It depends on usage and billing preference. SerpApi starts at $25 monthly for 1,000 searches. Serper’s first paid package is $50 for 50,000 credits and remains valid for six months. Compare your required volume and verify how your requests consume credits before treating the package rate as a per-query cost.
Can Serper replace SerpApi for non-Google search data?
Serper’s listed product focuses on Google search results and Google query types such as images, maps, shopping and Scholar. SerpApi lists APIs for Google and other search engines, along with services including Amazon, Bing, maps and jobs. If your application needs those other sources, SerpApi’s catalog is the closer fit.
What are the production rate limits?
SerpApi lists throughput per hour: its Production plan includes 3,000 per hour. Serper’s package tiers list 50, 100, 200 or 300 QPS. These are different units, so compare the limit against your request pattern and confirm the applicable limits with the vendor before launch.
Can I self-host either API?
Neither product is described as self-hostable; both are presented as hosted APIs. The vendors do not publish a self-hosting option in their product details. If data handling, retention or export requirements affect your architecture, ask each vendor for those terms and test your migration plan against its response format.
