Features
Entity-level diff analysis: parses changed functions, classes, methods, structs, and enums, not just files and lines
Graph-centric risk scoring with dependents and blast radius as the primary signals
Change classification: text (comments), syntax (signatures), functional (logic), or mixed
Union-Find grouping that untangles commits mixing independent logical changes
Four-phase pipeline (Extract, Classify, Score, Group) runs fully local with 0 API calls
Optional LLM review of top entities via Anthropic, OpenAI, or any OpenAI-compatible server
Local Ollama support with no API key for air-gapped or regulated environments
MCP server (inspect-mcp crate) with 6 tools for coding agents
ReviewVerdict output with four levels: LikelyApprovable, StandardReview, RequiresReview, RequiresCarefulReview
Markdown and JSON output formats available for all commands via --format
Analysis caching keyed by repo and target so repeat runs and drill-downs skip the 4-phase pipeline
Parallel graph building for large codebases
Installable via Homebrew tap or cargo install from GitHub

Rather than publish a score built on the wrong subject, we publish none.

Who should pick which

  • AI agent developer building RAG pipeline
    Pick: Spider Cloud

    Spider Cloud's Rust engine extracts markdown/JSON at $0.03/1k pages with 99.9% success, and its data connectors pipe results directly to cloud storage or databases.

  • Engineering lead reviewing PRs on large monorepo
    Pick: Inspect

    Inspect's graph-based risk scoring surfaces only structurally risky changes, reducing noise. Local execution means no data leaves your machine, and it's free.

  • Solo founder scraping competitor sites
    Pick: Spider Cloud

    The free tier plus AI Studio's natural language crawling lowers the barrier. Failed requests aren't billed, minimizing cost.

  • CI/CD pipeline engineer needing immediate PR triage
    Pick: Inspect

    Inspect runs as a CLI step, outputs JSON, and integrates with GitHub. No LLM required for core, so pipeline stays fast.

  • Security-conscious team reviewing agent-generated code
    Pick: Inspect

    Local-only analysis with optional LLM (bring your own key) ensures code never leaves your network. MCP tools let agents automate triage.

Can Spider Cloud handle CAPTCHAs?

Yes, Spider Cloud includes Silk custom AI model for CAPTCHA solving, plus stealth anti-detection and rotating proxies via the unblocker endpoint.

Does Inspect require an LLM?

No. Core triage uses entity extraction and graph analysis locally. Optional LLM review via 'inspect review' supports Anthropic, OpenAI, Ollama, or any OpenAI-compatible server.

What data formats does Spider Cloud output?

Structured output includes markdown, HTML, JSON, CSV, XML, and plain text. Screenshot capture is also available.

How many languages does Inspect support?

21 programming languages plus 5 data formats, using tree-sitter and sem-core for entity extraction.

Is Spider Cloud's pricing per request or subscription?

Spider Cloud uses a freemium model with usage-based billing. The AI Studio add-on is a flat $6/mo. Failed requests are not billed.

Can Inspect integrate with AI agents?

Yes, Inspect now includes an MCP server with 6 tools (inspect_triage, inspect_entity, etc.) for AI-agent integration. It also supports standard code review via GitHub.

Which tool is better for large codebases?

Inspect is specifically designed for large codebases with parallel graph building and per-phase timing (e.g., Sentry: 40s → 4s). Spider Cloud is for web data, not code.

Do these tools compete?

No. Spider Cloud is a web scraping API for AI agents; Inspect is a CLI code review tool. They serve completely different use cases and can be used together.
