Serper vs Zenserp: pros and cons

Serper
+ 2,500 free queries with no credit card — most accessible starting point for Google SERP data in this review
+ 1–2 second response times make it competitive for real-time Google result retrieval
+ 10+ search verticals (Web, Images, News, Maps, Videos, Shopping, Scholar, Patents, Autocomplete) in one API
+ Simple REST API with minimal setup — typically integrated and returning results within an hour
+ Positioned as cheapest Google SERP API — effective for cost-sensitive applications where coverage depth is secondary
- Google-only — no Bing, Amazon, YouTube, or other engine support unlike SerpAPI's 50+ engines
- Returns only Google's ranked results — no coverage-first enumeration, LLM validation, or event deduplication
- Very small bootstrapped team — limited enterprise support, SLA guarantees, or compliance documentation
- No documented SOC2, ISO, or GDPR certifications — not suitable for regulated industry pipelines
Zenserp
+ 100 free searches/month without a credit card — accessible for solo developers evaluating a Google SERP API
+ Transparent, publicly-listed pricing — no sales engagement required to understand cost at any volume
+ Single HTTP GET request to integrate — lowest onboarding overhead of any SERP API reviewed
+ Real-time results with geolocation and language targeting at no additional parameter cost
- Google-only — no Bing, Yahoo, or e-commerce engine support
- Fewer Google verticals than SearchAPI.io or SerpAPI — covers Web, Images, News, and Maps only
