Who should pick which
- AI agent developer needing real-time web data for RAGPick: Spider Cloud
Spider Cloud’s Rust engine, 99.9% success rate, and integrations with LangChain, LlamaIndex, and CrewAI make it ideal for feeding up-to-date web content into AI agents. The new Browser AI commands enable interactive scraping, and data connectors simplify pipeline automation.
- iOS app developer adding local AI featuresPick: Mirai
Mirai is purpose-built for on-device inference on Apple Silicon, offering quantization schemes co-designed with hardware and sparse KV cache for low-latency, memory-efficient AI. Perfect for ambient, interactive apps that cannot rely on cloud connectivity.
- Data scientist building large-scale web scraping pipelinesPick: Spider Cloud
With 1,000+ scraper examples, rotating proxies, and a cost of $0.03 per 1k pages, Spider Cloud handles high-volume extraction affordably. Data connectors pipe results directly to cloud storage, and failed requests are free.
- Researcher optimizing LLMs for Apple SiliconPick: Mirai
Mirai’s hardware-aware tensor optimization and new quantization method (June 2026) push speed-quality frontiers for local models. It’s the only tool with batch-size-1 inference engine designed specifically for M-series chips.
