Spider Cloud and kubbi solve entirely different problems: Spider Cloud fetches external web data for AI agents, while kubbi shuttles internal payloads between agents. Neither is a substitute for the other. Choose Spider Cloud if you need to scrape, crawl, or search the web for RAG; choose kubbi if you need a secure, ephemeral handoff mechanism within your multi-agent system. They can even complement each other in a single pipeline.

Features
Server-enforced burn-after-read deletes the payload when the retrieval limit is hit
TTL expiry configurable from 1 minute up to the per-plan maximum, with short defaults
AES-256-GCM encryption at rest with per-payload IV and auth tag
Manifest preview shows file names, sizes, and types before claiming
Multi-file packages delivered under a single claim URL
Producer-side inspect() and delete() for early cleanup
TypeScript SDK with KubbiClient.send() and sendFiles(), plus static claim and inspect
Python SDK with sync and async clients, plus standalone claim() and inspect() functions
REST API over HTTPS — Bearer auth for producers, claim URL token for consumers
MCP server exposing six native tools: kubbi_send, kubbi_send_files, kubbi_claim, kubbi_inspect, kubbi_get, kubbi_delete
Consumer claims with the URL alone — no API key or account required
Three terminal states (expired, burned, deleted) wipe the row and overwrite ciphertext on storage
Per-API-key rate limiting and rolling daily quota enforcement with 429 responses
Capability URL pattern: short-lived, unguessable reference carries no payload bytes
Inspect a kubbi's manifest without consuming the retrieval count
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

What real users say: kubbi vs Spider Cloud

Not marketing copy and not our opinion — a structured sweep of public discussion (reviews, forums, communities and video comments), showing what people praise and what they complain about for each tool.

kubbi

10 mentions across 1 sources · 50% positive — mixed (averaged across 1 source)

YouTube

What users praise

  • • Server-enforced burn-after-read prevents accidental payload leaks
  • • Short TTLs reduce window for unauthorized access
  • • AES-256-GCM encryption at rest with per-payload IV
  • • Multi-file bundles under one claim URL simplify complex handoffs

What frustrates them

  • • No community feedback or case studies yet — unproven in production
  • • Free tier TTL capped at 2 hours, limiting long-running workflows
  • • Claim URLs are bearer tokens — interception means data theft
  • • Payload size caps (16-256 KB) may be too small for many use cases

Spider Cloud

No verifiable community signal. We scanned public discussion on Oct 14, 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

  • RAG pipeline developer
    Pick: Spider Cloud

    You need fresh data from the web to feed into a vector database. Spider Cloud's crawling, scraping, and search APIs are explicitly built for this, with LangChain/LlamaIndex integrations and structured output.

  • Multi-agent system architect
    Pick: kubbi

    You need to pass large payloads between agents without storing them in chat histories or logs. kubbi's burn-after-read, TTL expiry, and encryption ensure secure, ephemeral transfers.

  • AI agent building web research tool
    Pick: Spider Cloud

    The browser AI commands (Act, Extract, Observe) and AI Studio allow natural language control of web interactions, perfect for agents that need to navigate websites and extract data.

  • Human-in-loop review pipeline
    Pick: kubbi

    You want to deliver sensitive data exactly once to a reviewer. kubbi's burn-after-read ensures the payload is claimed once and then destroyed, preventing replay or leaks.

  • Developer needing both data extraction and secure handoff
    Neither is a clear fit

    Use Spider Cloud to scrape data, then pass the output to another agent via kubbi's claim URLs. They are complementary: Spider Cloud gets the data, kubbi securely transfers it.

Frequently Asked Questions

kubbi vs Spider Cloud: which should you choose?

Spider Cloud and kubbi solve entirely different problems: Spider Cloud fetches external web data for AI agents, while kubbi shuttles internal payloads between agents. Neither is a substitute for the other. Choose Spider Cloud if you need to scrape, crawl, or search the web for RAG; choose kubbi if you need a secure, ephemeral handoff mechanism within your multi-agent system. They can even complement each other in a single pipeline.

Can I use Spider Cloud to pass data between agents like kubbi?

No. Spider Cloud is for fetching external web data, not for internal payload transfer. It has no claim-check mechanism or burn-after-read. Use kubbi for that.

Can kubbi scrape websites?

No. kubbi is a data transfer service, not a web scraper. It does not fetch external URLs. Use Spider Cloud for scraping.

What encryption does Spider Cloud use?

Spider Cloud uses TLS in transit. There is no mention of per-payload encryption at rest. kubbi uses AES-256-GCM per-payload with unique IV and auth tag, and data is encrypted at rest.

What is the payload size limit for kubbi?

The maximum payload size varies by plan: Free: 1 MB, Starter: 5 MB, Hobby: 10 MB, Pro: 20 MB, Team: 25 MB, Enterprise: custom. For files larger than 25 MB, Spider Cloud's data connectors or direct downloads are more appropriate.

Does Spider Cloud offer a free tier?

Yes, Spider Cloud's free tier includes 100 pages per month. kubbi's free tier includes 50 claims per month.

Which tool integrates with LangChain?

Spider Cloud integrates with LangChain, LlamaIndex, CrewAI, FlowiseAI, AutoGen, Agno, and Dify. kubbi integrates with MCP, A2A, webhooks, and queues but does not list LangChain integration.

Can I self-host Spider Cloud?

Yes, Spider Cloud has an open-source core available on GitHub for self-hosting. kubbi is a managed service only, with no self-hosted option mentioned.

What happens to a kubbi payload after it expires?

When a payload expires (TTL reached), is burned (retrieval limit hit), or deleted by the producer, the ciphertext is overwritten and the key is removed. The terminal states are expired, burned, or deleted, all wiping the row.
