If your goal is to build autonomous agents that call websites' internal APIs directly for speed and cost savings, Unbrowse is the innovative choice—its shadow API discovery and shared route graph can drastically reduce browser overhead. However, if you need to crawl at massive scale (100K+ URLs per request) with robust anti-blocking and structured data extraction for RAG pipelines, Spider Cloud is more mature and feature-rich, with a Rust engine, Silk AI extraction, and a new flat-rate plan. Choose Unbrowse for bleeding-edge API-level extraction; choose Spider Cloud for reliable, high-volume web data.

Frequently Asked Questions
Unbrowse vs Spider Cloud: which should you choose?
If your goal is to build autonomous agents that call websites' internal APIs directly for speed and cost savings, Unbrowse is the innovative choice—its shadow API discovery and shared route graph can drastically reduce browser overhead. However, if you need to crawl at massive scale (100K+ URLs per request) with robust anti-blocking and structured data extraction for RAG pipelines, Spider Cloud is more mature and feature-rich, with a Rust engine, Silk AI extraction, and a new flat-rate plan. Choose Unbrowse for bleeding-edge API-level extraction; choose Spider Cloud for reliable, high-volume web data.
Can Unbrowse handle JavaScript-heavy sites?
Unbrowse targets internal API discovery from browser traffic. For sites with heavily obfuscated or dynamic client-side APIs, coverage may be limited. It falls back to browser automation when routes are not yet discovered.
Does Spider Cloud respect robots.txt?
Yes, Spider Cloud respects robots.txt by default but allows configuring it per request to override if needed.
How does Unbrowse's shared route graph work?
When one agent browses a site and discovers an API route, that route is added to a shared graph. Subsequent agents can replay that route at near-zero cost without re-browsing.
What formats does Spider Cloud output?
Spider Cloud supports markdown, HTML, JSON, JSONL, CSV, XML, and plain text.
Does Unbrowse offer a Python SDK?
Yes, Unbrowse provides both TypeScript and Python SDKs, along with a CLI and MCP server.
Is Spider Cloud open-source?
Spider Cloud has an open-source fallback for self-hosting, but the cloud API is the primary offering.
Can Unbrowse be used for web scraping at scale?
Unbrowse is designed for API-level extraction. High-volume scraping may be less cost-effective than Spider Cloud because undiscovered routes incur browser costs.
What's the Silk AI model in Spider Cloud?
Silk is Spider Cloud's custom AI model for extracting structured data from HTML and solving captchas on-device, launched in March 2026.
