Kaiju Hub AI vs Lucid Train

Kaiju Hub AI is a workspace for building web, mobile, and desktop applications with AI-assisted tools. Project Hub brings project files, a terminal, task management, and version history together. The platform lists OpenAI, Anthropic, Gemini, Grok, DeepSeek, and Ollama as supported providers, and supports frameworks including React, Vue, Angular, Svelte, and Next.js. Wireframe tools let users arrange screens by drag and drop and generate code for React, Vue, Svelte, Angular, and SolidJS. It can analyze UI screenshots, identify elements, and turn them into wireframes or production code. Development integrations include Claude Code, Gemini CLI, Codex CLI, GitHub, and SDK modes for Claude, Gemini, and OpenAI. Web projects can be deployed to Vercel, Netlify, Railway, Fly.io, and Render. Block Library supports image and video generation, including local image generation through ComfyUI. The Free plan costs nothing and caps active projects and several other item types at five, with one active marketing campaign. Pro (monthly) costs $20 a month and lists unlimited active items in those categories. Prompts and project data may be processed by connected AI providers; users are responsible for provider API usage and costs.

Lucid Train is a desktop coding harness that draws architecture diagrams from a codebase and passes the diagram to a coding agent as a specification. The agent emits a semantic graph, and the ELK layout engine positions diagram elements and routes edges. Diagrams are Excalidraw scenes that can export to SVG and PNG or become Markdown specifications; Mermaid support and diagram import are also listed. Proposed edits appear as diffs, and commands use risk tiers, with catastrophic commands refused. Model options include local Ollama, OpenRouter, other OpenAI-compatible endpoints, and hosted cloud models. Repository files are processed locally; prompts and code go to the selected provider, or nowhere when using local models. The maker says it collects no telemetry, analytics, prompts, code, or usage data from local or bring-your-own-key sessions. API keys are stored locally or in the OS keychain. Connectors include GitHub, Vercel, Railway, and Grafana, plus arbitrary stdio MCP servers; remote HTTP and SSE servers cannot connect directly. The free CLI is open source. The native app costs $2.50 per month, billed $30 a year, and includes a 7-day free trial.
