|---|---|---|
| Pricing | Free open-source (self-host); cloud hosted upcoming | Free 100 pages/mo; $49/mo for 10,000 pages (renewable); $6/mo AI Studio add-on |
| Primary Function | Control plane for managing AI coding agents | Web scraping and crawling API for AI agents |
| Ease of Setup | Single-file architecture (amux-server.py); requires tmux & Python | API key, then send requests; dashboards and data connectors |
| Key Strengths | Self-healing watchdog, Kanban board, mobile app, agent-to-agent messaging | Rust engine, 99.9% success, $0.03/1k pages, AI Studio & Browser AI commands |
| Target Audience | Developers running multiple parallel coding agents | AI/LLM developers needing web data for RAG |
| Latest News | No recent news | Browser AI commands (Act, Extract, Observe); scraper catalog with 1,000+ examples |
If you need to feed web data into AI agents (RAG, LLMs), Spider Cloud is the clear choice — it's a purpose-built scraping API with a 99.9% success rate and low cost per page. For orchestrating multiple AI coding agents (e.g., Claude Code, Codex), Amux is a unique open-source control plane that handles parallel sessions, context compaction, and crash recovery. They solve entirely different problems: data ingestion vs. agent management.
AI web scraping API: crawl, scrape, search any site into markdown or JSON at 10k req/min.

Amux
35 mentions across 4 sources · 61% positive — mixed
Hacker News, App Store, GitHub, Lemmy
What users praise
- • Self-healing watchdog auto-compacts context and restarts crashed sessions reliably.
- • Manage agents from a mobile PWA or native iOS app anywhere.
- • Single-file architecture (amux-server.py) makes deployment trivial.
- • Kanban board with atomic task claiming via SQLite prevents collisions.
What frustrates them
- • Auto-update feature downloads and runs code from GitHub—major security risk.
- • APIs exposed on 0.0.0.0 without authentication allow remote file access.
- • No CLI command to list registered sessions; dashboard required.
- • Limited enterprise integrations and third-party plugin ecosystem.

Who should pick which
- LLM Developer building RAG applicationPick: Spider Cloud
Spider Cloud's scraping API provides clean, structured data (markdown, JSON) for indexing into vector databases. Its Rust engine ensures speed and reliability, and the AI extraction handles complex layouts.
- Developer running multiple AI coding agentsPick: Amux
Amux's dashboard and Kanban board make it easy to launch, monitor, and orchestrate many Claude Code or Codex agents. Self-healing and context compaction are critical for long-running sessions.
- Solo founder needing to scrape competitor data for AI analysisPick: Spider Cloud
Spider Cloud's 100-page free tier is enough to start, and cheap per-page pricing scales with need. AI Studio lets you describe scraping goals in natural language.
- Team wanting unattended overnight coding sprintsPick: Amux
Amux's scheduler and self-healing watchdog let you batch-code overnight with automatic recovery. The mobile PWA and iOS app give on-the-go oversight.
- Open-source contributor building agent orchestration toolsPick: Amux
Amux's single-file architecture and REST API allow easy customization and integration. The open-source community can extend it for new agent types.
Frequently Asked Questions
Amux vs Spider Cloud: which should you choose?
If you need to feed web data into AI agents (RAG, LLMs), Spider Cloud is the clear choice — it's a purpose-built scraping API with a 99.9% success rate and low cost per page. For orchestrating multiple AI coding agents (e.g., Claude Code, Codex), Amux is a unique open-source control plane that handles parallel sessions, context compaction, and crash recovery. They solve entirely different problems: data ingestion vs. agent management.
Can Spider Cloud scrape JavaScript-heavy sites?
Yes, Spider Cloud offers Browser Cloud with stealth anti-detection and AI-powered extraction (Silk custom model) to handle JavaScript-heavy sites. Its recent Browser AI commands (Act, Extract, Observe) via WebSocket further improve dynamic page handling.
Does Amux support non-tmux environments?
Amux is built on tmux for session isolation. Without tmux, the core functionality (managing agent sessions) may not work. Users in non-tmux environments would need to adapt or use alternative tools.
Which tool is better for a newcomer to AI agents?
For data ingestion, Spider Cloud's API is simple to integrate (just an API key and HTTP requests). For agent management, Amux has a learning curve due to self-hosting and tmux. A newcomer may start with Spider Cloud for data, then adopt Amux for orchestration as complexity grows.
Can Spider Cloud provide real-time data?
Yes, Spider Cloud's API returns data in real-time upon request. For continuous streaming, you can use data connectors to pipe results into S3, GCS, or others. The search endpoint also supports query-based data retrieval.
How do pricing models compare?
Spider Cloud charges per page (free 100, then $0.0049/page on Growth plan). Amux is free to self-host, with no usage-based fees. The total cost for Spider Cloud depends on crawl volume; Amux cost is server/infrastructure cost only.
Does Amux integrate with non-Claude agents?
Yes, Amux supports Claude Code, Codex, Gemini CLI, and any agent that can run in a terminal. The REST API allows integration with custom agents.
Which tool has better failure handling?
Spider Cloud does not bill failed requests and offers automatic retries with rotating proxies. Amux has a self-healing watchdog that restarts crashed sessions and compacts context to prevent memory bloat. Both are robust in their domains.
Can I use both tools together?
Absolutely. Spider Cloud can feed scraped web data into a LLM. That LLM can be one of the coding agents managed by Amux. For example, an agent using Claude Code (via Amux) can call Spider Cloud API to fetch live documentation. They are complementary.
