What makes Juno a great Heroku alternative
Heroku introduced a simple way to deploy apps — push code, and it ran in the cloud. It remains a solid choice for long-running, traditional web applications.
But today's stack is different. Modern apps favor lightweight deployments, usage-based execution, and infrastructure that doesn't require maintaining always-on containers.
Juno brings back Heroku-style simplicity for the modern era — giving you your own execution environment with no servers to manage and no platform control over your app.
The Trade-Off: Always-On Containers vs Modern Execution
Heroku runs long-lived app containers. This works well for classic backend apps, but means:
- You pay for uptime, even when idle
- You manage long-running processes
- Operational responsibility increases over time
With Juno, you still deploy your app — but it runs in a self-contained environment on demand, with no OS, runtime patching, or server process to maintain.
- You own the deployment
- No server or container administration
- No platform access to your code or data
Same simplicity — modern execution.
Feature Comparison
| Feature | Heroku (Traditional PaaS) | Juno (Modern Serverless) |
|---|---|---|
| Architecture | Always-on containers (dynos) | Self-contained containers, executed on demand |
| Deployment | Git push | CLI or Git-based deploy |
| Maintenance | App + container upkeep | You deploy updates; no OS to maintain |
| Data / Storage | Add-ons | Built-in datastore & storage (optional) |
| Authentication | External add-ons | Built-in decentralized auth (optional) |
| Core Benefit | Classic simplicity | Ownership, modern workflow, no server overhead |
Note: Juno isn't for persistent background workers or long-running processes. It's optimized for modern web apps.
Cost Considerations
Heroku is easy to start with, but costs rise as your app grows — especially if it needs background processes, add-ons, or multiple environments.
Juno keeps things simple. You pay for your own isolated app environment and the resources it actually uses over time — no per-feature charges, no surprise jumps, no scaling tax.
This means:
- Costs stay steady as your project evolves
- No extra fees for enabling auth, data, or functions
- You keep full control over how your app runs and spends
For long-term projects, Juno provides stability, ownership, and clarity — without managing servers and without unpredictable pricing.
When Juno Makes the Most Sense
Ideal for:
- Modern apps, dashboards, APIs, documentation sites
- Teams who want Heroku-style simplicity without servers
- Builders who value ownership and platform independence
- Projects that don't require persistent processes
Heroku still fits when:
- You need a long-running application server
- You're operating a legacy stack
- Your app has background jobs attached to the runtime
The takeaway
Heroku pioneered simple cloud deployment.
Juno builds on that spirit — but for modern workloads and developers who want ownership, privacy, and a lightweight execution model without managing infrastructure.
If you love Heroku's simplicity but want a platform designed for the next decade, Juno is a natural evolution.
