PlanetScale vs Spider Cloud

PlanetScale focuses on database performance and developer workflow. It offers Vitess horizontal sharding for MySQL to handle massive write/read throughput, and managed Postgres clusters starting at $5/month with unlimited IOPS on NVMe storage. Its branch-per-environment feature lets developers create full database branches for staging with prorated costs, while Database Traffic Control enforces query budgets. Online schema migrations are revertable and occur with zero data loss. High availability spans 3 AZs with auto-failover, and connection pooling via PgBouncer is built-in. In contrast, Spider Cloud is a web crawling/scraping API optimized for AI consumption. Its Rust engine processes 100K+ pages per second with a 99.9% success rate, outputting clean markdown, JSON, or screenshots. It includes stealth anti-bot bypass using proxies from 199 countries, AI extraction with schema enforcement and two-phase fallback, and relevance gating to avoid charging for irrelevant pages. It integrates deeply with AI frameworks like LangChain, LlamaIndex, and CrewAI, and supports webhooks and real-time streaming. While PlanetScale’s features are all about data storage and scaling, Spider Cloud’s are about data ingestion and structuring for AI models.

PlanetScale uses a subscription model with multiple tiers: Postgres clusters start at $5/month (presumably for small instances), while PlanetScale Metal begins at $50/month for higher performance with unlimited IOPS. Vitess sharding likely incurs additional costs based on size. There is no free tier mentioned. Spider Cloud uses pay-as-you-go pricing: $0.003 per page (likely after a certain threshold, e.g., 100K pages). This model is ideal for variable workloads or startups that only pay for what they use. Spider Cloud also offers an open-source crawler engine (MIT) that can be self-hosted, potentially eliminating API costs for those with infrastructure. PlanetScale’s pricing may be more predictable for steady-state database loads, whereas Spider Cloud’s metered billing suits occasional or scaling scraping needs.
