Choose backdoor if you want to use Claude Code’s agentic workflow with cheaper or local models, cutting costs dramatically. Choose Spider Cloud if you need a fast, reliable web scraping API with anti-bot capabilities for AI agents and RAG. They solve different problems; pick based on whether your bottleneck is AI model cost or fresh web data access.
Feature-by-feature
Backdoor is a lightweight proxy that reroutes Claude Code’s API calls to any OpenAI-compatible provider (DeepSeek, Groq, Ollama). It preserves Claude Code’s tool-use and agentic loop while offering cost savings up to 99.95% (e.g., 500M tokens for $5.34 vs $9,834 on Anthropic). Setup is terminal-based with a three-command wizard, and it supports streaming, private local inference, and access to 200+ models via OpenRouter. No telemetry is sent externally. Spider Cloud is a web scraping/crawling API built on a Rust engine for speed. It features a built-in Unblocker with stealth rotating proxies and a Browser Cloud for heavily protected sites. It supports 100K+ URLs per request, 10K requests/minute, automatic retries, and has endpoints for scrape, crawl, screenshot, links, and search. Output formats include JSON, CSV, XML, markdown, HTML, and raw text. Integrations include LangChain, LlamaIndex, CrewAI, FlowiseAI, AutoGen, and Agno. Failed requests are billed at $0, and it boasts a 99.9% success rate with $0.03 average cost per 1,000 pages. The two are complementary: backdoor reduces AI inference costs; Spider Cloud provides fresh web data for agents.
Pricing compared
Backdoor is completely free and open-source. Users only pay for the model provider’s API costs, which can be much cheaper than Anthropic (e.g., DeepSeek, Groq free tier, local Ollama). This makes it ideal for high-volume usage where cost per token is critical. Spider Cloud operates on a freemium model with pay-as-you-go pricing. While specific tier prices are not disclosed, it claims $0.03 average cost per 1,000 pages, with failed requests free. This is competitive with Firecrawl and Bright Data. For heavy scrapping, costs are usage-based. There is no monthly subscription mentioned, so budgeting depends on volume. Backdoor’s free pricing is best for cost-conscious developers; Spider Cloud’s pay-per-use suits variable scraping needs. Both have low entry barriers: backdoor is $0 software, Spider Cloud offers a free tier.
