Overview

What is Juno?

Juno is a serverless platform reimagined for developers who demand security, privacy, and simplicity without operational overhead. Built on decentralized infrastructure, it runs each project in its own isolated WASM container that you exclusively control—combining the familiar developer experience of traditional cloud platforms with the resilience and autonomy of self-hosting.

Core Capabilities

Juno provides a complete backend-as-a-service toolkit: user authentication, a flexible datastore, file storage, static site hosting, serverless functions, analytics, monitoring, and automated snapshots. Developers can scaffold projects instantly using built-in templates and deploy modern web applications without managing servers, databases, or infrastructure.

Who Should Use Juno?

Ideal for teams building decentralized applications, privacy-focused products, or anyone seeking cloud convenience without vendor lock-in. The platform supports TypeScript, JavaScript, Rust, and Svelte workflows, with Docker-based local development for contributors. Whether you're launching a blog, SaaS application, or Web3 project, Juno eliminates the gap between rapid prototyping and production-ready deployment.

Highlights

Isolated WASM containers per project for exclusive control and security
Complete backend suite: auth, datastore, storage, hosting, and serverless functions
Decentralized infrastructure with zero operational complexity
Instant scaffolding with templates and Docker-based local development

Pros

  • No server management or DevOps overhead required
  • Strong security through isolated container architecture
  • Decentralized infrastructure eliminates vendor lock-in
  • Comprehensive feature set covering most backend needs

Considerations

  • Decentralized infrastructure may introduce unfamiliar deployment patterns
  • Smaller community compared to established cloud platforms
  • Limited documentation for advanced customization scenarios
  • Requires understanding of WASM container model for optimization

Fit guide

Great for

  • Teams building privacy-first or decentralized applications
  • Developers seeking cloud convenience without vendor dependencies
  • Projects requiring rapid backend scaffolding with minimal configuration
  • Applications needing built-in analytics and monitoring without third-party tools

Not ideal when

  • Organizations requiring compliance with specific cloud provider certifications
  • Projects deeply integrated with AWS, Azure, or GCP ecosystems
  • Teams needing extensive enterprise support and SLAs
  • Applications with complex legacy infrastructure migration requirements

How teams use it

Decentralized SaaS Application

Launch a multi-tenant application with authentication, database, and file storage while maintaining full control over infrastructure and user data privacy.

Privacy-Focused Content Platform

Deploy a blog or media site with built-in hosting, analytics, and monitoring that respects user privacy without relying on third-party tracking services.

Rapid Prototype Development

Scaffold and deploy a full-stack application in minutes using templates, eliminating backend setup time and accelerating time-to-market.

Web3 Application Backend

Build decentralized apps with serverless functions and datastore capabilities that align with blockchain-based frontend architectures.

Frequently asked questions

What makes Juno different from traditional serverless platforms?

Juno runs on decentralized infrastructure with each project in an isolated WASM container you control, eliminating vendor lock-in while providing familiar cloud-like developer experience.

Do I need to manage servers or infrastructure?

No. Juno handles all operational complexity, including scaling, monitoring, and maintenance, so you can focus entirely on building your application.

What languages and frameworks does Juno support?

Juno supports TypeScript, JavaScript, Rust, and Svelte. You can scaffold projects using built-in templates and integrate with standard web development workflows.

Can I run Juno locally for development?

Yes. Juno provides Docker-based local development environments. Docker Desktop 4.25.0 or later is recommended for MacBooks with M processors.

Is Juno suitable for production applications?

Yes. Juno includes production-ready features like authentication, analytics, monitoring, and automated snapshots, designed for modern web applications requiring security and reliability.
