The zero-config database built for the vibe-coding era.

💡 The Problem

When building apps with AI tools like Cursor, Bolt.new, v0, or Lovable, setting up a database is always a bottleneck. You end up spending more time writing schemas, configuring connections, or managing localstorage syncing than writing actual features.

⚡ The Solution

CloudState is a zero-config persistence layer designed to work natively with AI code generation. It gives you a persistent, secure JSON endpoint in under 10 seconds.

Copy-paste our custom system prompt into your LLM editor or .cursorrules, and let the AI sync your app state dynamically using simple fetch requests.

🌟 Key Features

• ⚡ Zero Configuration: Skip schemas, migrations, and database provisioning. If it’s valid JSON, CloudState will store it.

• 🤖 Tailored LLM Prompts: Copy-paste project-specific system prompts directly into Cursor, Bolt, or Lovable to teach the AI exactly how to read and write your state.

• 🔒 Concurrency Protection: Built-in optimistic locking via the x-version header prevents concurrent users or multi-agent runs from overwrites.

• 🚀 Ultra-low Latency: Built with Hono on the edge and Neon Serverless PostgreSQL (JSONB) for sub-30ms operations.

• 🔌 Pure Fetch API: No bloated SDKs required. Use standard fetch() GET to read and PUT to overwrite.

🛠️ How It Works (in 10 seconds)

1. Initialize: Create a project on cloudstate to get your unique endpoint slug and API key.

2. Integrate: Drop the auto-generated prompt into your AI assistant.

3. Sync: Let the AI read and write state directly:

   javascript

   // Overwrite state

   await fetch("https://cloudstate.onrender.com/v1/db/your-project", {

   method: "PUT",

   headers: { "x-api-key": "your_api_key" },

   body: JSON.stringify(state)

   });
