Primary Use CaseShared memory + coordination for multi-agent coding fleetsWeb crawling & scraping for AI agents & RAG pipelines
Core TechnologyBi-temporal graph database (MemDB), built in RustRust engine with stealth anti-detection & rotating proxies
Latest News ImpactNew open-source tool Enola released (2026-07-02) — deterministic architecture graphsBrowser AI commands (Act/Extract/Observe) + scraper catalog (1k+ examples) + data connectors
Target AudienceTeams running multiple AI coding agents (Cursor, Claude Code, etc.)AI developers needing web data for RAG or LLM context
Privacy & HostingSelf-hosted (local laptop), no LLM calls, code never leavesCloud API with open-source self-host fallback

If you run a fleet of AI coding agents and need shared memory with conflict detection, Memtrace is purpose-built—but it's waitlist-only and weakens for single-agent setups. For web data retrieval powering AI agents or RAG, Spider Cloud offers a proven, low-cost API with real-time scraping features and recent Browser AI commands. Choose Memtrace for coordination, Spider Cloud for data.

Scrape a single page into markdown, JSON, HTML, raw text, or plain text
Crawl entire sites with each page streamed as one JSONL line in order the moment it finishes
Web search endpoint returns SERP results plus the scraped pages behind them in one call
Custom browser renders like a user: scripts run, lazy images load, infinite scroll completes
Unblocker loads protected pages through a real browser engine with geo checks and a 200
Browser Cloud runs full sessions 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 the 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
Requests stream back as they land, in order, without waiting for the last URL

Spider Cloud

No verifiable community signal. We scanned public discussion on Oct 7, 2026 and found posts matching the name “Spider Cloud”, but could not establish that they are about this product rather than something else sharing its name. Rather than publish a score built on the wrong subject, we publish none.

Who should pick which

  • Solo founder building RAG app
    Pick: Spider Cloud

    Spider Cloud offers a low-cost, usage-based API for web crawling and scraping, perfect for injecting real-time data into a RAG pipeline. It's immediately available with a freemium tier.

  • Engineering team running multiple AI coding agents on a monorepo
    Pick: Memtrace Public

    Memtrace's bi-temporal graph database and fleet coordination prevent context loss and merge conflicts when many agents edit code simultaneously. However, note the waitlist requirement.

  • Developer needing real-time web data for LLM tool
    Pick: Spider Cloud

    Spider Cloud's Browser AI commands (Act, Extract, Observe) via WebSocket and fast Rust engine make it ideal for agent tools that need structured web data quickly.

  • Privacy-conscious team avoiding external API calls
    Pick: Memtrace Public

    Memtrace runs locally and requires zero LLM calls, keeping code and context private. However, it is currently waitlist-only and may not be immediately accessible.

  • Team needing web scraping at high volume with anti-detection
    Pick: Spider Cloud

    Spider Cloud's stealth anti-detection, rotating proxies, and unblocker endpoint are designed for large-scale scraping without being blocked, with a low cost per page.
