The best Fly.io alternative — flat pricing, full control
Fly.io's per-VM billing, egress fees, and pricing complexity catch developers off guard. DeployWise deploys your apps to your own VPS for a flat ~$5/mo — no metered bandwidth, no surprise invoices, fully open-source.
Fly.io advertises cheap per-VM pricing — a shared-cpu-1x starts at $1.94/mo. But real apps need persistent storage ($0.15/GB/mo), dedicated IPv4 ($2/mo), and bandwidth ($0.02/GB egress after free tier). A simple Node.js app with a database and moderate traffic can easily cost $15-25/mo — more than a VPS that includes everything.
With a VPS + DeployWise, you pay one flat price. A Hetzner CX22 gives you 2 vCPU, 4GB RAM, and 20TB of transfer for ~$5/mo. DeployWise is free. No meters, no surprises.
Why developers leave Fly.io
Fly.io bills per-VM, per-GB of egress, per-GB of persistent storage, and per-dedicated-IPv4 address. A shared-cpu-1x VM is $1.94/mo — sounds cheap until you add a volume ($0.15/GB/mo), a dedicated IP ($2/mo), and bandwidth that scales with traffic. Developers routinely report surprise bills 3-5x what they expected.
Fly.io charges $0.02/GB for outbound bandwidth after the free allowance. Serving a moderately trafficked API or app with images can easily burn through 100GB+/mo — adding $2+ to your bill that you didn't see coming. Most VPS providers include 20TB of transfer for free.
Fly.io has experienced several high-profile outages affecting their control plane and machine orchestration. When Fly.io's platform goes down, you lose the ability to deploy, scale, or even access your running apps. With a VPS, your app stays running even if DeployWise's dashboard is temporarily unavailable.
Fly.io's private networking relies on WireGuard tunnels via flyctl. Developers frequently hit DNS resolution failures, tunnel drops, and connectivity issues between machines. Debugging these issues requires understanding Fly.io's custom networking layer — a far cry from standard VPS networking.
Not all Fly.io regions offer the same VM sizes or pricing. Deploying to certain regions costs more, and some machine types aren't available everywhere. With a VPS provider like Hetzner, you pick a datacenter and get a flat price — no surprises, no region surcharges.

DeployWise vs Fly.io — feature comparison
Fly.io wins on managed databases and multi-region edge. DeployWise wins on pricing transparency, server access, and open-source freedom.
Edge vs single region — when it actually matters
Fly.io's biggest selling point is edge computing: your app runs in data centers close to your users worldwide. But for most apps, this doesn't deliver the performance gains you'd expect.
If your app talks to a database, the database lives in one region. Every request still round-trips to that region regardless of where the app runs. Edge only helps if your app is stateless or uses region-local data.
For static assets, images, and cached API responses, a free CDN like Cloudflare delivers the same edge performance. Put Cloudflare in front of your VPS and static content is served from 300+ edge locations — for free.
A VPS in Frankfurt with Cloudflare CDN serves a European user in ~20ms for cached content and ~50ms for dynamic requests. Fly.io edge might save 10-30ms on dynamic requests — a difference most users can't perceive.
Real-time multiplayer games, edge-native databases (like Fly.io's LiteFS), and apps with users evenly distributed across 5+ continents. If that's you, Fly.io is the better tool.
What you get with DeployWise instead
DeployWise is an open-source deployment tool that turns any VPS into a modern app platform. No vendor lock-in, no metered billing, no proprietary CLI.
Push to GitHub and DeployWise automatically builds and deploys your app. No flyctl, no fly.toml — just git push.
Your app runs 24/7 with automatic restarts on crash, zero-downtime reloads on deploy, and cluster mode for multi-core utilization.
DeployWise configures Nginx as a reverse proxy and provisions Let's Encrypt SSL certificates automatically. No manual cert management.
Already have a Dockerfile from Fly.io? DeployWise uses it as-is. No need to rewrite your deployment configuration.
Set env vars through the dashboard. They're encrypted at rest and injected at runtime — just like Fly.io secrets, but simpler.
SSH into your VPS anytime. Install packages, debug in production, run database backups — it's your server, your rules.
Migrate from Fly.io to DeployWise in 3 steps
No fly.toml to translate. No WireGuard to configure. If your app runs in Docker or Node.js, you can migrate in under 10 minutes.
Grab a VPS from Hetzner, DigitalOcean, or any provider. A $5/mo instance (2 vCPU, 4GB RAM at Hetzner) replaces multiple Fly.io VMs. Add the server to DeployWise with one click.
Link your repository in the DeployWise dashboard. If you have a Dockerfile, DeployWise uses it. For Node.js apps, it auto-detects your framework and sets up PM2 with zero-downtime reloads.
Hit deploy. DeployWise configures Nginx as a reverse proxy, provisions SSL via Let's Encrypt, and starts your app. Update your DNS records to point to your VPS IP. Done — no fly.toml, no flyctl, no WireGuard.
When Fly.io is still the right choice
Fly.io is a powerful platform for specific use cases. Here's when we'd still recommend it:
For single-region apps, APIs, and web apps where predictable pricing and full server control matter more than edge distribution — DeployWise on a VPS is the smarter choice.
Other Fly.io alternatives worth considering
Developer-friendly PaaS with usage-based pricing. Simpler than Fly.io but still has variable costs. Good for prototyping, expensive for production.
Managed platform with a free tier. Cold starts on free, $7+/mo for always-on. Simpler pricing than Fly.io but less control than a VPS.
The sweet spot: Hetzner's unbeatable VPS pricing (~$5/mo for 2 vCPU, 4GB RAM, 20TB transfer) paired with DeployWise's free deployment layer. Flat cost, full control.
TL;DR — Fly.io vs DeployWise
Fly.io is built for edge computing and multi-region deployments. It's excellent for globally distributed, stateless apps and Elixir/Phoenix workloads. But its per-VM + per-GB pricing model makes costs unpredictable for most apps, and its WireGuard-based networking adds operational complexity that many teams don't need.
DeployWise is built for developers who want Vercel-style git-push deploys on infrastructure they own. It's best for single-region apps, APIs, and web apps where you want flat pricing, full SSH access, and zero platform lock-in. It's free and open-source — you only pay for your VPS.
If your app talks to a database in one region and serves users primarily in one geographic area (which describes the vast majority of web apps), DeployWise on a $5/mo VPS will outperform Fly.io on cost while delivering equivalent performance with a CDN like Cloudflare in front.
Frequently asked questions
Fly.io offers a limited free allowance — 3 shared-cpu-1x VMs with 256MB RAM each. However, egress bandwidth, persistent storage, and dedicated IPs are billed separately, so real-world usage almost always incurs charges.
Fly.io bills per-VM, per-GB egress ($0.02/GB after free allowance), per-GB persistent volume, and for dedicated IPv4 addresses ($2/mo each). Machines left running in multiple regions or bandwidth-heavy apps cause bills to spike unexpectedly.
Yes. If your app runs in a Docker container or as a Node.js/Next.js project, you can migrate in under 10 minutes. Connect your VPS, link your GitHub repo, and deploy. DeployWise handles Nginx, SSL, and PM2 automatically.
Yes. DeployWise supports Docker-based deployments alongside native Node.js deployments with PM2. You can use your existing Dockerfile without modification.
Fly.io excels at multi-region edge deployments. If your app genuinely needs to run in 10+ regions simultaneously, Fly.io is a better fit. For the vast majority of apps serving users from one or two regions, a single VPS with a CDN (like Cloudflare, free) delivers equivalent performance at a fraction of the cost.
Yes. DeployWise is 100% free and open-source. You only pay for your VPS hosting (typically $4-6/mo). There are no platform fees, no per-app charges, and no usage-based billing from DeployWise itself.
DeployWise automatically provisions and renews SSL certificates via Let's Encrypt when you connect a custom domain. There's no manual configuration needed — it configures Nginx with HTTPS and handles certificate renewal automatically.
Yes. DeployWise uses Nginx as a reverse proxy and PM2 for process management, so you can run multiple apps on a single VPS, each on its own domain. A $5/mo Hetzner VPS with 4GB RAM can comfortably run 3-5 Node.js applications.
