Features
Runs coding agent CLIs as persistent background servers that survive sleep, close, and reboot
Reattach to live agent sessions over SSH from any machine
Real PTY-backed terminals instead of tmux or screen multiplexing
Per-pane agent status: working, blocked, or idle
Agent-native CLI and local JSON socket API — the same surface agents drive
Agents split panes, start each other, prompt each other, and wait on a blocked peer
22 agent CLIs detected out of the box
Supports Claude Code, Codex, Cursor, opencode, Grok, Copilot, Hermes, and Pi
Version 0.9: local and remote machines in one TUI client with a combined agent list
Add remote machines over SSH with independent reconnects per machine
Single Rust binary for macOS, Linux, and Windows (beta), Apache-2.0 licensed
No account and no telemetry required
Installs via curl, Homebrew, Nix, or the Windows install script
Session state: detach, restart restore, pane history replay, and native agent resume
Live server updates replace without killing running pane processes
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

Hacker News, Lemmy

What users praise

  • • Reattach from any SSH-capable device, including phone.
  • • Real PTY per agent, not tmux/screen multiplexing fakes.
  • • Visual agent status (working, blocked, idle) at a glance.

What frustrates them

  • • Steep learning curve for tmux/nvim veterans.
  • • Windows support is beta and may be buggy (WSL issues).
  • • Docs confusing about model provider support (e.g., Vercel AI gateway).
  • • Missing customization options (colors/font/sizing) for daily-driver use.
