Opt-in stochastic atoms (injection_free, tone, relevance) can call any LLM judge
CLI wizard auto-detects framework and IDE, drafts contracts, patches entry file
Native OpenTelemetry export of traces and verdicts to Datadog, Honeycomb, Grafana
Redirects blocked calls to human approval (escalate_to_human) mid-run

Scrape a single page into markdown, JSON, HTML, raw, or plain text
Crawl entire sites with each page streamed as one JSONL line in order as it finishes
Web search endpoint returns SERP results plus the scraped pages behind them
Custom browser renders like a user: scripts run, lazy images load, infinite scroll reaches the end
Load protected pages through a real browser engine with geo checks, returning a 200
Run full browser sessions over WebSocket with anti-detection and rotating exits
Send AI commands (Act, Extract, Observe) over the Browser API WebSocket
Send a prompt on a scrape or crawl request and get named fields back as JSON
Two-phase AI extraction: a fast model for most pages, a stronger model for complex layouts
Provider router sends scrape and crawl requests to outside providers on your own keys
Data connectors pipe crawl results into S3, GCS, Google Sheets, Azure Blob, or Supabase
Proxy network with 215M+ residential and ISP exits in 199 countries, rotated per request
MCP server at mcp.spider.cloud for Claude Code, Codex, Cursor, and Claude Desktop
1,000+ ready-made scraper examples across 32 categories, each with working code
API responses support JSON, JSONL, CSV, and XML; up to 10,000 core API requests per minute by default

  • • Sub-10 microsecond latency per tool call keeps agent performance fast.
  • • Natural-language policy compilation reduces manual rule writing effort.
  • • Pre-built contracts cover OWASP Agentic Top 10 risks in one line.

What frustrates them

  • • Community feedback is nearly absent — no real-world validation available.
  • • Version 0.1 implies immature code and likely breaking changes.
  • • Only two relevant community posts exist across all platforms.
  • • Off-topic board game results pollute search and discovery efforts.
