Deep dive: Netlify
When to choose Netlify
Netlify is the best choice for teams building static sites, JAMstack applications, or framework-agnostic projects (Vue, Svelte, Gatsby, Hugo). Choose it if branch previews are central to your development workflow, stakeholder feedback cycle, or if you're hosting 10+ projects under a single account. It's wrong for Next.js applications where Vercel provides superior optimization and DX. Also wrong if you need compute-heavy functions with sub-second response times, strict cold-start SLAs, or heavy asynchronous job processing. Skip Netlify if you're likely to outgrow build-minute limits—the free tier provides only 300 minutes/month, and overage costs ($1 per additional minute) add up quickly for teams with monorepos or slow test suites.
Real-world use case
A 4-person design agency deployed 8 client Gatsby sites to Netlify, paying zero dollars for hosting. Each client received a unique domain, automatic branch preview links for stakeholder feedback, and one-click rollbacks for emergency fixes. After adding 2 more client sites, they hit the 300 free build-minute monthly limit and upgraded to $19/month Pro tier (3000 minutes/month). Their total DevOps overhead: effectively zero. Rolling back a broken deploy took literally 1 click and 10 seconds. The avoided alternative was AWS S3 + CloudFront ($50+/month) plus 2 hours monthly maintenance, and Heroku ($100+/month). Their Netlify stack saved each of 8 clients from needing to hire a $120k DevOps engineer or pay ongoing hourly DevOps consulting fees.
Hidden gotchas
Netlify Functions have brutal cold starts: 5-10 seconds on free tier for Node.js functions, making them unsuitable for latency-sensitive APIs. Pro tier improves to 1-2 seconds but still underperforms AWS Lambda significantly. The 300 build-minute monthly limit catches teams by surprise—one monorepo with slow test suites or large dependency trees burns through it in days; no automatic overage warnings or alerts. Form submissions require external backend integration; Netlify doesn't auto-collect form data to email. Environment variables aren't encrypted at rest in the free tier (only on Pro+), creating security concerns. Free tier's 100GB bandwidth is shared across all sites on your account, not allocated per-site. API redirects (rewrites) work but have a 10KB response body limit, breaking larger API responses. Custom domain setup requires pointing nameservers to Netlify; A-record pointing alone breaks CDN caching. Built-in analytics are basic with no custom event tracking.
Pricing breakdown
Netlify's free Starter plan includes 100 GB bandwidth, 300 build minutes, and 1 concurrent build — generous for personal projects. The Pro plan at $19/user/mo unlocks 1 TB bandwidth, 25,000 build minutes, and background functions. The real cost escalation comes from serverless functions ($25 per 2M invocations beyond free tier) and bandwidth overages ($55 per 100 GB). For a team of 3 running a medium-traffic site, expect $60-120/mo on Pro. Enterprise pricing is custom but typically starts around $1,000/mo.
Deep dive: Fly.io
When to choose Fly.io
Fly.io is the choice for teams prioritizing global latency and willing to embrace Docker-native deployments. Pick Fly if you're running containerized apps needing presence in 35+ regions, want sub-100ms latency for users worldwide, or need competitive per-minute pricing without AWS's complexity tax. It's ideal for: real-time apps (gaming, live collaboration), geographically distributed teams, teams already proficient with Docker/containers, and developers who value control. Fly becomes the wrong choice when: your team is Docker-unfamiliar and learning curve is a blocker, you need managed PostgreSQL as your primary feature (it exists but is clunky), you want one-click deployments without CLI involvement, or your app is static/JAMstack (overkill and expensive). The steep learning curve isn't marketing hype—it's real. Developers report spending 2-3 days getting first deployments stable. Cost-wise, Fly stays cheap only if you optimize aggressively; inefficient container configs create billing surprises.
Real-world use case
A European SaaS company building a real-time collaborative editor chose Fly.io to compete with giants by offering true sub-50ms latency in 12 regions. They deployed a Node.js app in Docker containers. Month 1 cost: $15 (minimal traffic). By month 6 with 5,000 active users, costs stabilized at $120/month—$80 for compute, $40 for managed PostgreSQL and volumes. Their latency metrics: US-East 45ms, EU-Central 12ms, APAC 98ms. The tradeoff: a single engineer spent 1 week debugging volume persistence (Fly volumes don't replicate automatically), discovering users' data disappeared on container restarts. They learned to use PostgreSQL instead of local volumes. Deployment to production took 2 minutes from git push via Fly CLI. The hidden win: Fly's pricing remained predictable; no surprise jumps like Heroku or Render. When they hit 10k users, scaling from 2 to 4 container instances cost just $30 more.
Hidden gotchas
Volumes (local storage) don't auto-replicate—data loss is a trap for developers assuming distributed storage works like managed services. PostgreSQL on Fly.io has a config gotcha: SSL must be explicitly enabled in connection strings, otherwise production deployments succeed but apps mysteriously fail at runtime. Memory limits are enforced harshly—a Node.js app with a memory leak will be OOMKilled without warning; logs show only 'received signal SIGKILL.' The CLI requires constant authentication; tokens expire silently, causing cryptic 'unauthorized' errors mid-deploy. Billing is per-minute and can spike if apps crash in loops—a buggy deploy restarting every 10 seconds costs 3x as much as expected. Fly's Postgres requires manual read-replica setup (unlike Render's one-click managed database), adding complexity. Building Docker images locally and pushing to Fly's registry has undocumented size limits (image layers over 5GB fail silently). IPv6-only deployments are the default; legacy clients expecting IPv4 see 'connection refused' errors. Cold starts exist on free tier despite marketing claims of 'no cold starts'—they happen after 30 days of inactivity.
Pricing breakdown
Fly.io offers a free allowance of 3 shared-CPU VMs (256 MB each), 3 GB persistent storage, and 160 GB outbound transfer per month. Beyond that, shared-CPU VMs start at $1.94/mo (1 shared CPU, 256 MB). Dedicated-CPU VMs start at $31/mo (1 CPU, 2 GB RAM). Egress is $0.02/GB after the free tier. The pricing model is usage-based — you pay for uptime, not requests. For a globally distributed app with 3 regions, expect $15-50/mo for a lightweight service. The gotcha: persistent volumes are region-locked and cost $0.15/GB/mo, and multi-region Postgres requires a volume per region.
Should You Use Netlify or Fly.io?
For most teams, Netlify is the better default: it offers framework-agnostic and is freemium (from $19/month). Choose Fly.io instead if true global deployment matters more than build minutes limited on free tier. There is no universal winner — the right pick depends on your budget, team size, and whether you value framework-agnostic or true global deployment more.
Choose Netlify if…
