Hacker News, Product Hunt, App Store, Stack Overflow, Lemmy
What users praise
- • Keeps GNU screen's session model and C-a bindings, so screen users migrate with almost no relearning
- • Parses every session through libghostty-vt, enabling faithful SGR styles, cursor, and terminal mode redraws
- • Headless send, peek, and wait work without a TTY, making agent scripting practical
- • peek prints reconstructed screen state rather than raw bytes, cutting parsing work for automation
What frustrates them
- • No corroborated user feedback anywhere — all 62 scraped posts are off-topic name collisions
- • Deliberately drops tmux's panes, plugins, and status-bar customization, limiting workspace layout
- • Name is nearly impossible to search for help, given Boo the language and BOO! video chat
- • No documented integration ecosystem or editor plugins to extend the automation primitives

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 and boo share almost no surface. Spider Cloud is a hosted API: one POST scrapes a page into markdown, JSON, HTML, or raw text, crawls a whole site streaming one JSONL line per finished page, or runs a web search that returns SERP results plus the scraped pages. Its rendering layer runs scripts, waits on lazy images, follows infinite scroll, and — via the Unblocker — loads protected pages with geo checks. The Browser Cloud runs full sessions with anti-detection and CAPTCHA solving, and newer Browser AI commands (Act, Extract, Observe) go over the Browser API WebSocket, requiring an AI Studio subscription. AI extraction now runs two-phase: a fast model for most pages, a stronger model for complex layouts. A Provider router can send requests to outside providers on your own keys, and data connectors pipe crawl output into S3, GCS, Google Sheets, Azure Blob, or Supabase. boo is the opposite shape: a local, free multiplexer built on libghostty-vt and written in Zig. It keeps GNU screen's session model (Ctrl-A d to detach, boo attach to return) but fixes screen's redraws using libghostty terminal state — SGR styles, cursor, scrolling regions, window title, terminal modes. Automation is the differentiator: send, peek, and wait work without a TTY, with boo wait --text blocking until text appears and --timeout exiting 4 instead of hanging. There is no overlap to weigh; you would run boo on your machine while calling Spider Cloud from your pipeline.
Pricing compared
These are not price tiers of the same product. boo is free and MIT-licensed — no plans, no seats, no usage meter; you install it and the only cost is your own time. Spider Cloud is freemium with a metered pay-as-you-go path and an Unlimited flat-rate tier aimed at high-throughput crawls where flat-rate concurrency beats per-request billing. The catch, stated in its own positioning: geo-targeting isn't available on Unlimited, so geo-fenced crawls stay on pay as you go, and residential/ISP proxies plus AI extraction bill separately — meaning budget owners who want one all-in rate won't find it here. Unlimited also queues nothing server-side, so your app has to handle HTTP 429. Comparing the two numerically is meaningless: one has a free license, the other has plans. If your question is 'what will this cost me,' the honest answer is that boo costs nothing and Spider Cloud costs whatever your scrape and crawl volume, proxy usage, and AI extraction add up to on the tier you choose.
Who should pick which
- RAG pipeline builderPick: Spider Cloud
Whole-site crawls streaming markdown JSONL per page, plus connectors into S3, GCS, Sheets, Azure Blob, or Supabase.
- AI agent developerPick: Spider Cloud
One API key covers scraping, search, browser sessions, and proxies, with LangChain, LlamaIndex, CrewAI, MCP, and Claude Code integrations.
- Sysadmin running long jobsPick: boo
Detach with Ctrl-A d and reattach later, with redraws faithful to libghostty terminal state instead of screen's mangled output.
- CI/CD engineerPick: boo
send, peek, and wait run without a TTY, and boo wait --timeout exits 4 rather than hanging a pipeline.
- Script or agent authorPick: boo
boo wait --text and --idle plus boo peek --json let you read the screen exactly as a human would, predictably.
Frequently Asked Questions
Could I use Spider Cloud from inside a boo session?
Yes, and that's the closest these two get to meeting: run your scraper or agent script inside a persistent boo session. It's a stacking relationship, not a choice between products.
Does boo have a hosted or paid version?
No. It's free and MIT-licensed, built on libghostty-vt and written in Zig. There is no cloud tier to buy.
Does Spider Cloud need a TTY to run?
Nothing in its data says so — it's an HTTP API, so the TTY question is boo's domain. boo explicitly supports headless send, peek, and wait.
Is Spider Cloud's Unlimited tier really unlimited?
It's positioned as flat-rate Unlimited concurrency rather than metered per-request billing, but geo-targeting isn't available there and it queues nothing server-side, so your app must handle HTTP 429.
What does boo offer tmux or screen users?
Screen users get the familiar session model with better redraws; tmux users who rely on panes, splits, and layouts won't find them here, per its own not-for list.
