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.
Feature-by-feature
Spider Cloud's capabilities are all about acquisition of external web content: single-page scraping to markdown/JSON/HTML/text, whole-site crawls streaming back JSONL as each page finishes, a search endpoint that returns SERP results plus scraped pages plus AI extraction in one call, a custom browser that executes scripts and completes infinite scroll, an unblocker for CAPTCHAs and geo checks, full Browser Cloud sessions, and 215M+ residential/ISP proxies across 199 countries. The new provider router lets scrape and crawl bodies route requests to outside providers on your own keys, with mode off keeping a URL on Spider's stack.
Amplitude goes the opposite direction: it measures behavior inside your own product. Behavioral cohorts, funnels, conversion drivers, Session Replay, heatmaps, feature flags, A/B/n and web experimentation, in-app guides and surveys, and marketing campaign reporting. Its AI layer — Global Agent, Agent Analytics, AI Feedback — plus a consolidated MCP server means an agent can query Amplitude data from Claude or Cursor.
The genuine intersection is the MCP/client surface. Spider Cloud exposes MCP at mcp.spider.cloud with a CLI and SKILL.md so a coding agent self-onboards; Amplitude exposes MCP tools and now Global Agent inside Discord. One gives agents data from the open web; the other gives agents answers about your users. Different inputs, different outputs.
Pricing compared
Both are freemium, but the meters measure unrelated things, so no apples-to-apples comparison exists. Spider Cloud bills per request on pay-as-you-go, with flat-rate Unlimited concurrency as the alternative for high-throughput crawls. Two cost traps are explicit in the data: residential/ISP proxy pools and AI extraction bill separately from base request pricing, and geo-targeting is not available on Unlimited, so geo-fenced crawls must stay on pay as you go. Unlimited also queues nothing server-side — your client must handle HTTP 429 and back off.
Amplitude gives every plan the full platform and unlimited seats, then charges on events once you outgrow Free into Growth or Enterprise. Its own data flags pre-seed teams with no instrumentation budget as a bad fit because setup time exceeds the value returned.
So the budgeting question isn't which is cheaper — it's which meter you can forecast. Spider Cloud scales with how many pages you fetch; Amplitude scales with how many events your product emits. A heavy crawl workload can be cheaper on Unlimited than metered scraping, and Amplitude's unlimited seats make it cheaper per person than seat-priced analytics, but those are savings against each product's own alternatives, not against each other.
Who should pick which
- AI engineer building a RAG ingestion pipelinePick: Spider Cloud
Crawl whole documentation sites with pages streaming back as JSONL and send a prompt with each request to get named fields as JSON — exactly the ingest path RAG needs.
- Developer giving Claude Code or Cursor live web accessPick: Spider Cloud
MCP at mcp.spider.cloud plus the spider-agent CLI and SKILL.md let the agent self-onboard; LangChain, LlamaIndex, and CrewAI integrations cover the rest of the stack.
- Product manager diagnosing where users drop offPick: Amplitude
Funnels, conversion drivers, behavioral cohorts, and Session Replay with network context show the drop; Global Agent then answers follow-ups in natural language.
- Growth team running A/B tests and feature flagsPick: Amplitude
Feature Experimentation tied to flags and cohort targeting, Web Experimentation with version history, plus new scheduling for experiment stops and consent-gated test runs.
- Team shipping an AI agent and needing to prove it helpedPick: Amplitude
Agent Analytics measures how agent experiences drive retention and revenue, and AI Feedback converts user comments from any channel into cohorts and actions.
Frequently Asked Questions
Could I use Spider Cloud and Amplitude together?
Yes, and that's the only sensible way to pair them. Feed Spider Cloud's scraped pages into your agent or pipeline, then use Amplitude's MCP server to query what users did afterward. They occupy opposite ends of the same workflow.
What happens to Spider Cloud requests if I use the new provider router?
Routing a request to an outside provider runs it on your own keys; leaving the mode off keeps that URL on Spider's stack. It's a per-request choice inside the scrape and crawl body, not an account-wide setting.
Does Amplitude's MCP consolidation change how my agents connect?
Amplitude consolidated its MCP tools into fewer endpoints on the Platform, which changes how agents connect to Amplitude data. If you built against the previous tool set, re-point your client at the consolidated endpoints.
Where is Amplitude's Global Agent available beyond the Amplitude app?
Discord, as of the August 2026 release, in addition to its existing surface. That means product data queries can happen in a chat client rather than only in the analytics UI.
Can I run geo-fenced crawls on Spider Cloud's Unlimited plan?
No — geo-targeting isn't available on Unlimited yet, so geo-fenced crawls have to stay on pay as you go. That's a hard routing constraint, not a preference.
Why would a pre-seed team avoid Amplitude?
The data is blunt about it: with no instrumentation budget, setup time exceeds the value you'll get. Amplitude rewards teams that already have event discipline and someone to own it.
Does Amplitude charge per seat like most analytics tools?
No — every plan includes unlimited seats and the full platform. Pricing scales on events instead, which is why the Free-to-Growth transition is the moment to plan for.
What does Spider Cloud need from my client at high volume?
Unlimited queues nothing server-side, so your client has to handle HTTP 429 responses and back off on its own. If your code can't do that, stay on the metered pay-as-you-go path.
