**Verdict: Perplexity is the easier vibe code** — 75/100 (Solid side project) vs 15/100.

| | Google | Perplexity |
|---|---|---|
| Vibecodeability | 15/100 | 75/100 |
| Tier | Don't bother | Solid side project |

| SaaS bill replaced | Free ($0) | $20/mo (Pro) |
| Category | Search Engine | AI Search Engine |

## The case on Google

Keep paying, or rather keep using it for free — you cannot clone Google Search because its value is an entire web index and global infrastructure.

Hardest parts:

- Indexing tens of billions of web pages with sub-second retrieval latency
- Distributed web crawling infrastructure respecting robots.txt and rate limits
- Training and serving multimodal LLMs and ranking models at global scale
- Handling global concurrent traffic volumes with zero perceived downtime

## The case on Perplexity

You can build a functional personal answer-engine clone in 1-3 weeks, but replicating their custom Vespa-backed real-time web indexing architecture is out of reach.

Hardest parts:

- Building low-latency real-time retrieval pipelines over fresh web indexes
- Deterministic inline citation anchoring mapped back to retrieved URLs
- Balancing context window limits against multiple fetched web page contents
- Prompt engineering and multi-model routing to ensure reliable structured JSON output
