Fly.io vs Heroku for low-maintenance app hosting

For low-maintenance app hosting, Heroku is usually the easier choice if your priority is “deploy it and forget it.” Fly.io is more flexible and can be cheaper/more capable for certain workloads, but it usually asks a bit more from you.

Quick take

Choose Heroku if you want:

• the simplest developer experience
• very little infrastructure management
• easy deploys, logs, add-ons, SSL, scaling
• a platform that feels “boring” in a good way

Choose Fly.io if you want:

• more control
• global deployment / edge-ish routing
• better fit for apps that need to run close to users
• potentially lower cost for small apps, depending on usage
• you’re okay with a little more ops knowledge

Maintenance comparison

Heroku

Pros

• Extremely straightforward app deployment
• Mature ecosystem and add-ons
• Minimal DevOps work
• Good documentation and a familiar PaaS model

Cons

• Can get expensive as you grow
• Fewer knobs for advanced infrastructure patterns
• Some users feel it’s less “modern” or flexible than newer platforms

Fly.io

Pros

• Very capable for containerized apps
• Great for running apps near users geographically
• Can be cost-effective
• Good if you like Docker-first workflows

Cons

• More infrastructure concepts to learn
• You may spend more time dealing with regions, volumes, networking, and deployment details
• “Low-maintenance” is possible, but it’s not as hands-off as Heroku

If your app is…

A small web app / API / MVP

• Heroku: best for lowest hassle
• Fly.io: good if you want global distribution or are comfortable with Docker

A production app with modest traffic

• Heroku: easiest to operate
• Fly.io: worth considering if cost or latency matters

Something geographically distributed

• Fly.io is usually the better fit

A team that doesn’t want to think about servers

• Heroku is still the classic choice

My practical recommendation

If your goal is specifically low-maintenance hosting, I’d pick:

• Heroku for simplicity and predictability
• Fly.io only if you specifically need its strengths (global deployment, more control, Docker-native workflow, or potentially lower cost)

If you want, I can also give you a decision table based on app type, budget, and team size, or a “which one should I choose for my stack?” recommendation.
