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.
AI web scraping API: crawl, scrape, search any site into markdown or JSON at 10k req/min.

10 mentions across 1 sources · 50% positive — mixed
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

Who should pick which
- RAG pipeline developerPick: 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 architectPick: 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 toolPick: 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 pipelinePick: 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 handoffPick: both
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.

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.
