Bolt generates an app from a conversation: the AI writes the code and connects a backend service such as Supabase. Luna Park also builds with AI, but the result is visual logic you can read and edit without code, compiled to a Vue and Node.js application.
At a glance
Both build apps with AI. The main differences: what the AI produces, AI choice, and backend.
| Luna Park | Bolt | |
|---|---|---|
| How you build | Visual editor, with an AI assistant | Conversation with an AI |
| What the AI produces | Components, logic graphs, routes, tables | JavaScript and TypeScript code |
| Editing without AI | Visually, no code | By editing the code |
| AI model | Any provider, a local model, or your coding agent | Chosen by Bolt |
| Backend | Routes, crons, PostgreSQL | A backend service, such as Supabase |
| Pricing | Free, or Pro at €25/month or €300 once. AI on your own key | Tokens, also spent reading your project (source) |
| Platforms | Web PWA Desktop Android iOS | Mostly web |
Example: a waitlist form
Visitors enter their name, email, and favorite ride, and get a ticket number.
Luna Park
- Ask Sidekick for the form, or build it yourself.
- The result is a graph: read the fields, call the route, show the ticket.
- Sidekick tests it by calling the route and clicking through the preview. Test data is rolled back.
Bolt
- Prompt: "add a waitlist form that saves to the database".
- The AI writes the component, the table, and its access rules.
- To change it, prompt again or edit the code.
Code export
Both give you the code. Luna Park compiles the visual project to Vue and Node.js, so you can keep working visually or take the code.
Other differences
- Understanding the app. With Bolt, fixing a bug means reading generated code or prompting again. In Luna Park, components, graphs, routes, and tables are visual, and the app map shows how they connect.
- AI costs. Bolt spends tokens on each request, including reading your project, so costs grow with its size. Luna Park uses your own key, a local model in the desktop app, or your coding agent (Claude Code, Codex, Cursor...) through MCP. Editing without AI is free.
- Data access. Luna Park routes run next to PostgreSQL, behind guards you can read.
- Structure. Projects keep a fixed file structure and types shared by frontend and backend.
Which one to choose?
Luna Park
- You want to understand and fix your app yourself.
- You want to choose your AI.
- Your project will outgrow a prototype.
Bolt
- You want the AI to write a code base for you.
- You are comfortable maintaining the generated code.
Before switching
- Sidekick needs your own API key or a local model.
- Until managed hosting launches in late 2026, you host the backend.
