What is Juno

Juno is a developer platform that combines the ease of traditional cloud services with the benefits of blockchain technology. It provides all the tools you need to build modern applications: user authentication, data storage, file hosting, website deployment, and serverless functions.

What makes Juno special is that everything runs on blockchain in containers you own. This means no company controls your data or can shut down your app. Your users get better privacy because their information stays secure and private by default.

The platform is open source and runs on the Internet Computer Protocol, which allows your websites and apps to run entirely from blockchain without depending on traditional web hosting. Developers can use familiar coding patterns while getting blockchain benefits automatically.

FAQ's About Juno

Is Juno really free to use?
Yes, Juno provides free credits for new developers to create their first project container. You can build and test applications without any upfront costs. You only pay for additional containers (0.4 ICP each) and actual resource usage like storage and computation.
How is Juno different from Firebase or AWS?
Unlike Firebase or AWS, Juno runs entirely on blockchain rather than centralized servers. This means you truly own your applications and data - no company can access your information or shut down your projects. Your apps are also naturally resistant to censorship and downtime.
Do I need to know blockchain development to use Juno?
No! Juno is designed for regular web developers. You can use familiar languages like JavaScript and TypeScript with normal development patterns. The blockchain complexity is handled automatically, so you can focus on building your product.
What is the Internet Computer Protocol (ICP)?
ICP is a blockchain network that can host websites and applications directly on-chain. Unlike other blockchains that only run smart contracts, ICP can serve web pages, store files, and handle user requests entirely from blockchain infrastructure.
Can I migrate my existing app to Juno?
Yes! Juno supports popular frameworks like React, Vue, Svelte, and Next.js. You can gradually migrate features from your existing backend to Juno's blockchain services, or deploy a complete new version. The JavaScript SDK provides familiar APIs that work like traditional backend services.
