Can I use Codedb without an AI agent?

No. Codedb is designed exclusively as an MCP server for AI agents. It doesn't provide a standalone IDE interface.

Does Spider Cloud require a subscription?

No. Spider Cloud is pay-as-you-go starting from $1/GB bandwidth; no monthly subscription needed.

Does Codedb support remote repositories?

Yes. Codedb includes a remote repo query feature, allowing agents to query codebases not stored locally.

What is AI Studio in Spider Cloud?

AI Studio is a $6/month add-on that enables natural language crawling instructions, simplifying data extraction without coding.

Which tools integrate with Codedb?

Codedb works with any MCP-capable agent, notably Claude Code, Codex, Cursor, and Windsurf.

How does Spider Cloud handle anti-bot measures?

Spider Cloud includes an Unblocker with rotating proxies and automatic retries, plus a silent browser cloud to evade detection.

Is Codedb production-ready?

Yes. The latest v0.2.13 ships with macOS signing, Zig 0.17 build, and measured performance improvements. However, it's a daemon that requires self-hosting.
