Netlify
Platform for modern web development
The pioneer of Git-based web deployment with the most generous free tier in static hosting, combining CDN delivery, serverless functions, and built-in services like forms and auth in one platform.
Fly.io
Deploy app servers close to users
The only platform that makes multi-region application deployment trivially easy — run full application servers (not just edge functions) close to users in 35+ cities worldwide using Firecracker micro-VMs with Anycast routing.
Overview
Netlify
Netlify pioneered the Jamstack movement, fundamentally changing how developers think about deploying websites. Founded in 2014, the platform introduced the idea that static sites deployed to a CDN, enhanced with serverless functions, could replace traditional server-rendered web applications for most use cases. Today, Netlify hosts millions of sites for companies including Peloton, Vince, and Unilever, and has expanded well beyond static hosting into a comprehensive web development platform with CI/CD, serverless functions, edge computing, forms processing, identity management, and more.
Git-Based Deployments
Netlify's core workflow is beautifully simple: connect a Git repository (GitHub, GitLab, or Bitbucket), and Netlify automatically builds and deploys your site on every push. The build system detects your framework — Next.js, Gatsby, Hugo, Astro, Nuxt, Eleventy, or any of dozens of others — and runs the appropriate build command. Deploy previews create a unique URL for every pull request, letting teams review changes in a real environment before merging. Instant rollbacks let you revert to any previous deployment with one click. This Git-centric workflow means your deployment history mirrors your commit history, making auditing and debugging straightforward.
Serverless Functions and Edge
Netlify Functions let you run server-side code without managing servers. Write a JavaScript or TypeScript function, drop it in a directory, and Netlify deploys it as an AWS Lambda function accessible via an API endpoint. This is perfect for form handling, API proxying, authentication callbacks, and webhook processing. Netlify Edge Functions run on Deno at the edge (close to users), enabling geolocation-based personalization, A/B testing, authentication checks, and response transformation with sub-millisecond cold starts. The combination of traditional serverless and edge functions covers most backend needs without a dedicated server.
Built-In Services
Netlify bundles several services that typically require separate tools. Netlify Forms captures
form submissions from static HTML forms without any server-side code or JavaScript — add a
netlify attribute to your form tag and submissions go to your Netlify dashboard or
get forwarded via webhook. Netlify Identity provides authentication and user management with
JWT-based auth, social login (Google, GitHub, etc.), and role-based access control. Netlify
Large Media handles Git LFS for images and large files with built-in image transformation.
These built-in services reduce the number of third-party services a typical site needs.
Build Plugins and Extensibility
Netlify's build plugin system lets you hook into the build process to run custom logic.
Community plugins handle common tasks: optimizing images, generating sitemaps, checking for
broken links, purging CDN caches, and running Lighthouse audits. You can write custom plugins
for project-specific needs. The Netlify CLI lets you develop and test locally with
netlify dev, which emulates the production environment including serverless
functions, edge functions, and environment variables.
Pricing and Free Tier
Netlify's free tier (Starter) is one of the most generous in web hosting: 100GB bandwidth, 300 build minutes, 1 concurrent build, serverless functions (125K invocations), deploy previews, and HTTPS with custom domains. The Pro plan at $19/member/month adds 1TB bandwidth, shared environment variables, background functions, and password-protected sites. Business at $99/member/month adds SAML SSO, audit logs, and higher limits. For most personal projects, portfolios, and small business sites, the free tier is genuinely sufficient. The per-member pricing on paid plans, however, makes Netlify expensive for larger teams.
Limitations
Netlify's biggest limitation is that per-member pricing on paid plans scales poorly for teams. A 10-person team on Pro costs $190/month — compared to Vercel's $20/month for the same tier. Build times for large sites can be slow, and the 300 free build minutes get consumed quickly by monorepos or sites with frequent commits. Next.js support, while improved, is not as seamless as Vercel's (Next.js's creator) — advanced features like ISR and middleware sometimes behave differently. And Netlify's attempt to be everything (forms, identity, LFS) means each individual service is good but rarely best-in-class compared to dedicated solutions.
Fly.io
Fly.io is a platform founded in 2017 that transforms Docker containers into micro-VMs running on bare-metal servers in 35+ regions worldwide. While most hosting platforms deploy your application to a single data center (or at best, two), Fly.io's core promise is multi-region deployment by default — your application runs close to your users in cities like Amsterdam, Tokyo, Sao Paulo, Johannesburg, Sydney, and Chicago, with requests automatically routed to the nearest healthy instance. The platform was built by a team of infrastructure veterans who believed that edge computing should not require the complexity of Kubernetes or the limitations of serverless functions. Fly.io uses Firecracker (the same micro-VM technology created by AWS for Lambda and Fargate) to provide lightweight, secure isolation with near-instant startup times.
Firecracker Micro-VMs
Unlike platforms that use containers (shared kernel) or traditional VMs (heavy overhead), Fly.io runs applications in Firecracker micro-VMs that combine the security isolation of VMs with the speed and efficiency of containers. Each micro-VM boots in milliseconds, uses minimal memory overhead, and provides hardware-level isolation between tenants. This architecture means your application gets a dedicated kernel, filesystem, and network stack — stronger isolation than Docker containers — while still being lightweight enough to run in dozens of regions simultaneously.
Multi-Region by Default
Deploying to multiple regions on Fly.io is a single command: fly scale count 3 --region ams,nrt,iad places instances in Amsterdam, Tokyo, and Washington DC. Fly.io's Anycast network automatically routes each user's request to the nearest healthy instance. For applications with a primary database, Fly.io provides read replicas and request routing that sends writes to the primary region while serving reads locally. This architecture achieves the latency benefits of a global CDN while running full application servers — not just cached static content — close to users.
Fly Machines and GPUs
Fly Machines is the low-level API that gives you direct control over micro-VMs: start, stop, suspend, and resume machines programmatically with sub-second response times. This enables architectures where machines spin up on demand for each user session, function invocation, or build job, and stop when idle — paying only for active time. Fly.io also offers GPU machines for AI/ML workloads, providing access to NVIDIA A100 and L40S GPUs in select regions, enabling model inference close to users rather than in a centralized data center.
Built-in Postgres and Storage
Fly.io offers Fly Postgres — a managed PostgreSQL deployment that runs as Fly apps on your account. Unlike fully managed databases from AWS or Render, Fly Postgres gives you direct access to the underlying VM, allowing custom PostgreSQL configuration while automating replication and failover. LiteFS enables distributed SQLite with automatic replication across regions — ideal for read-heavy applications that benefit from local reads. Tigris (S3-compatible object storage) is integrated for file storage needs. Volume storage provides persistent NVMe-backed disks attached to individual machines.
Pricing and Considerations
Fly.io offers a free tier with up to 3 shared-CPU machines, 256MB RAM each, and 3GB persistent volume storage. Paid usage is billed per second: shared-CPU VMs start at approximately $1.94/month, and dedicated-CPU VMs from $29/month. The usage-based model is cost-effective for applications with variable traffic, as stopped machines incur no compute charges. However, multi-region deployments multiply costs linearly — running 3 instances across 3 regions means 9 machines. The platform's CLI-centric workflow, while powerful, has a steeper learning curve than GUI-first platforms like Render or Railway, and the documentation, while improving, can be inconsistent for some advanced scenarios.

Use Case Recommendations
Best uses for Netlify
Agency Deploying Client Sites
Web agencies use Netlify to deploy dozens of client sites on the free tier, with deploy previews for client review, instant rollbacks for production issues, and Git-based workflows that match their development process. Each client site gets its own Netlify project with a custom domain.
Documentation and Marketing Sites
Companies host their documentation (built with Docusaurus, Hugo, or Astro) and marketing sites on Netlify. Deploy previews let content and marketing teams review changes before they go live, while the CDN ensures fast loading times globally.
Jamstack E-commerce Storefronts
Developers build headless e-commerce sites with frameworks like Next.js or Gatsby, using Shopify or Stripe for the commerce backend and Netlify for hosting and deployment. Edge Functions handle geolocation-based pricing and A/B testing of checkout flows.
Open Source Project Websites
Open source projects host their documentation and landing pages on Netlify's free tier. Deploy previews on pull requests let contributors preview documentation changes before merging, and the generous free bandwidth handles traffic spikes from Hacker News or Reddit.
Best uses for Fly.io
Globally Distributed Web Applications
Applications serving users worldwide deploy to Fly.io's 35+ regions so that API requests and page loads are served from the nearest data center. A real-time collaboration tool or chat application achieves sub-50ms response times globally instead of 200-500ms from a single region.
Edge API and Application Servers
Teams that need full server-side logic (not just cached responses) running close to users deploy application servers on Fly.io. Unlike CDN edge functions with execution time limits, Fly.io runs full application servers — Node.js, Python, Go, Elixir — with persistent connections, WebSockets, and database access.
On-Demand Compute and Sandboxed Environments
Platforms that need to run user code or spin up isolated environments per session use Fly Machines to create and destroy micro-VMs on demand. Code execution platforms, browser testing services, and AI inference endpoints benefit from sub-second startup times and per-second billing.
Elixir and Phoenix Applications
Fly.io has a strong affinity with the Elixir/Phoenix community, as the platform's distributed architecture aligns naturally with Elixir's distributed computing model. Phoenix applications can leverage Fly.io's clustering to connect BEAM nodes across regions for real-time features and global presence.
Learning Curve
Netlify
Low for basic deployment — connect a repo and deploy in under 5 minutes. Serverless Functions require basic Node.js knowledge and take a day to learn. Edge Functions and build plugins take a few more days. The Netlify CLI for local development is well-documented. Most developers are fully productive within a week.
Fly.io
Moderate. Deploying a basic application requires understanding the flyctl CLI, fly.toml configuration file, and concepts like regions and machines. Developers comfortable with command-line tools and Docker can deploy their first app in 15-30 minutes. Multi-region architectures, Fly Machines API, database replication strategies, and volume management require deeper study. The platform rewards infrastructure-minded developers who appreciate the flexibility of micro-VMs but may feel complex to developers accustomed to GUI-driven platforms.
FAQ
Is Netlify free tier enough for production sites?
For most personal projects, portfolios, small business sites, and even medium-traffic blogs, yes. The 100GB bandwidth handles roughly 100K-500K page views per month depending on page size. You get deploy previews, HTTPS, custom domains, and serverless functions. The main limitations are 300 build minutes (may not be enough for sites with frequent deploys) and 125K serverless function invocations. Most sites never exceed the free tier limits.
How does Netlify compare to Vercel?
Both offer Git-based deployment, serverless functions, and edge computing. Vercel is better for Next.js projects (it's built by the same team), offers better per-team pricing ($20/month flat on Pro vs $19/member), and has superior serverless function performance. Netlify is more framework-agnostic, has better built-in services (forms, identity), and its free tier includes more bandwidth. Choose Vercel for Next.js; choose Netlify for static sites, Hugo, Gatsby, or multi-framework agencies.
How does Fly.io compare to Railway and Render?
Railway and Render deploy applications to a single region with simpler workflows and more polished dashboards. Fly.io deploys to multiple regions by default with Anycast routing, providing lower latency for global audiences. The trade-off is complexity: Fly.io requires CLI comfort and understanding of multi-region concepts, while Railway and Render prioritize ease of use. Choose Fly.io when global latency matters; choose Railway or Render when deployment simplicity is the priority.
What is included in Fly.io's free tier?
The free tier (Hobby plan) includes up to 3 shared-CPU-1x machines with 256MB RAM each, 3GB persistent volume storage, and 160GB outbound bandwidth per month. This is sufficient for running a small application in 1-3 regions. Additional machines, dedicated CPUs, more memory, and GPU access are billed at usage-based rates. Stopped machines do not incur compute charges, only volume storage fees.
Which is cheaper, Netlify or Fly.io?
Netlify starts at Free / $19/mo Pro, while Fly.io starts at Free tier / Usage-based. Consider which pricing model aligns better with your team size and usage patterns — per-seat pricing adds up differently than flat-rate plans.
