Frequently Asked Questions
Plannotator vs Spider Cloud: which should you choose?
Plannotator and Spider Cloud serve fundamentally different needs. Plannotator is ideal for developers who want a rich, privacy-focused UI to review and annotate plans and diffs from AI coding agents. Spider Cloud excels at high-volume web scraping and data extraction for AI pipelines. Choose Plannotator if your bottleneck is agent plan quality and approval workflow; choose Spider Cloud if your team needs reliable, scalable web data to feed LLMs or RAG systems.
Can I use Plannotator with Spider Cloud together?
Yes, they serve different purposes. You could use Spider Cloud to scrape web data, and Plannotator to review any AI agent plan that uses that data — but there is no direct integration.
Does Plannotator require an internet connection?
Plannotator runs locally in the browser and can work offline. Sharing via encrypted URLs uses the internet only to generate the shareable link.
Is Spider Cloud suitable for small projects?
Yes, its free tier and low per-page cost make it accessible for small-scale scraping. For sporadic use, it may be more cost-effective than a monthly subscription.
Does Plannotator support image or rich media annotation?
No, Plannotator focuses on markdown plans, code diffs, and HTML. It does not support image annotation natively.
What output formats does Spider Cloud support?
Markdown, HTML, JSON, CSV, XML, plain text, and screenshots. You can also extract links and get structured data via AI extraction.
Can I self-host Spider Cloud?
Yes, Spider Cloud has an open-source core available on GitHub for self-hosting, but the cloud version offers additional features like rotating proxies and AI extraction.
Does Plannotator have a mobile app?
No, Plannotator is browser-based and not optimized for mobile. It works best on desktop browsers.
Which one is better for a team of 10 developers?
For code review and plan annotation, Plannotator scales via self-hosting. For web data needs, Spider Cloud scales via its API and data connectors. The choice depends on your primary workflow.
