How Devii Works
Transform your SQL database into a production-ready GraphQL API in minutes. Skip weeks of manual API development and start building AI-powered applications today.
1
Connect Database
Paste your connection string and let Devii instantly discover your schema. Works with MySQL, PostgreSQL, Oracle, and more—no drivers or config files needed.
2
Configure Security
Set up policy-based access control in clicks, not code. Define who sees what data with granular permissions that actually make sense to humans.
3
Review Schema
Preview your auto-generated GraphQL schema with all queries, mutations, and relationships mapped perfectly. Make tweaks if needed, or just hit publish.
4
Start Querying
Your production-ready API is live! Copy the endpoint, grab your auth tokens, and start building. No servers to manage, no code to maintain.
THE TRANSFORMATION
Say goodbye to REST APIs that return kitchen-sink responses when you only wanted a spoon. GraphQL gives you exactly what you ask for; revolutionary concept, we know. But here's why it matters: faster AI applications that don't waste bandwidth or processing power on unnecessary data.

Frequently asked questions
With Devii, you can have a production-ready GraphQL API running in under 30 seconds. Simply connect your database, and our engine automatically generates the complete schema, resolvers, and security policies. Most developers are making their first API calls within minutes of signing up.
Devii works with all major SQL databases including MySQL, PostgreSQL, Oracle, Microsoft SQL Server, Azure SQL, MariaDB, and even SQLite. Our universal database translator handles the differences between systems, so you get the same powerful GraphQL interface regardless of your backend.
Absolutely. Devii uses policy-based access control (PBAC) with deny-by-default security that meets enterprise, government, and university requirements. SQL injection is impossible thanks to our built-in expression parser, and you get granular permissions without the complexity of traditional role-based systems.
GraphQL is perfect for AI applications because it lets you request exactly the data you need—no more, no less. This reduces bandwidth, speeds up processing, and gives AI models cleaner, more focused datasets. Plus, GraphQL’s strong typing helps catch errors before they reach your AI pipeline.
Yes! While Devii automatically generates your complete API, you maintain full control over what’s exposed. Choose which tables and columns are accessible, set custom permissions, add server-side functions like email sending and PDF generation, and configure complex relationships—all without writing resolver code.
Devii automatically detects schema changes and updates your GraphQL API in real-time. Add a new table, modify columns, or update relationships—Devii reflects these changes instantly. Your API documentation updates automatically too, so your team always has current information.
