Who should pick which

  • Backend architect in a NestJS project
    Pick: Solarch

    Solarch's architecture-first diagram canvas and default-deny Rules Engine enforce clean layers and dependencies, ensuring code matches the design. Its CLI and VS Code extension detect drift, critical for maintaining architecture over time.

  • AI agent developer needing real-time web data
    Pick: Spider Cloud

    Spider Cloud's Rust engine provides fast, reliable scraping at low cost. Its Browser AI commands and AI extraction enable agents to autonomously gather structured data from the web, with integrations into LangChain and other agent frameworks.

  • Solo developer building a RAG pipeline
    Pick: Spider Cloud

    Spider Cloud's easy-to-use API, structured output, and data connectors to S3/Supabase simplify pipeline setup. The freemium tier and low per-page cost make it affordable for small projects.

  • Team enforcing CI/CD architecture compliance
    Pick: Solarch

    Solarch's drift detection in CI/CD via CLI and VS Code extension ensures that any code changes violating the architecture are caught early. The deterministic codegen reduces manual review.
