Google CSE (Post-2027) vs Modern Search APIs (Scavio, Tavily, SerpAPI)
Google Custom Search Engine closes to new signups in 2026, and existing instances lose the ability to search the entire web on January 1, 2027. After that date, CSE only searches pre-configured whitelisted sites. Modern search APIs provide full-web search, structured SERP features, and multi-platform data that CSE never offered. This comparison shows what teams lose by staying on CSE and what they gain by switching.

Feature-by-feature comparison
Verdict
Google CSE is a dead-end for any project that needs full-web search. After January 2027, it only works for pre-configured whitelisted sites, making it useless for general search, AI grounding, or content discovery. The only reason to stay on CSE is if you exclusively need to search a fixed set of domains you control. For everything else, modern search APIs provide more data, more platforms, and more features at comparable or lower cost.
Consider Scavio instead
Scavio replaces CSE with structured Google search at the same $5/1K query cost, plus five additional platforms (YouTube, Amazon, Walmart, Reddit, TikTok) and structured SERP features (AI Overview, Knowledge Graph, PAA) that CSE never provided. The 250 free credits/month ease migration testing. MCP server at mcp.scavio.dev/mcp adds agent integration CSE cannot match.

Some teams use both tools for different parts of their pipeline. However, a unified API like Scavio can replace the need for multiple subscriptions by providing search, content extraction, YouTube, and Amazon data from a single endpoint.
