Netlify ToolingThe modern web platform for JAMstack and beyond
Netlify pioneered the JAMstack movement — combining static sites, serverless functions, and edge computing into a seamless developer workflow. We build and deploy fast, scalable sites on Netlify for teams that value simplicity.
Netlify helped define the modern JAMstack movement — the architectural approach of pre-rendering static pages, enhancing with JavaScript, and connecting to APIs and serverless functions for dynamic behavior. The platform turns any Git repository into a deployed website: push to main and Netlify builds, deploys, and serves your site on a global CDN with HTTPS, branch previews, and instant rollbacks. It supports virtually every static site generator and frontend framework — Astro, Next.js, Nuxt, SvelteKit, Hugo, Gatsby, and plain HTML. Beyond static hosting, Netlify provides a serverless backend layer. Serverless Functions (powered by AWS Lambda) deploy alongside your site with zero configuration. Edge Functions (powered by Deno) run at the edge for personalization, auth, and response transforms. Netlify Forms captures submissions from any HTML form without a backend. Netlify Identity provides JWT-based authentication. Together, these features let you build full-featured applications without managing any infrastructure. Netlify's sweet spot is marketing sites, documentation, blogs, and content-driven applications — projects where build-time rendering, CDN delivery, and simple serverless functions cover the majority of needs. For complex server-side applications, Netlify's serverless model has limits (function execution caps, cold starts, no persistent connections). A Major builds on Netlify when it's the right fit and helps teams evaluate when a more flexible platform is needed.
Quick start
# Install Netlify CLI
npm install -g netlify-cli
# Create and deploy an Astro site
npm create astro@latest my-site
cd my-site
netlify init
netlify deploy --prod
# Or link an existing repo
netlify link
netlify deploy --prodRead the full documentation at docs.netlify.com/
Instant builds & deploys
Git-triggered builds with atomic deploys, instant rollbacks, and deploy previews for every pull request — zero-downtime deployments every time.
Serverless Functions
AWS Lambda-powered serverless functions with zero configuration — deploy alongside your site, automatic API routing, and background functions for long tasks.
Edge Functions
Deno-based edge functions running at 300+ locations — transform responses, personalize content, handle auth, and run A/B tests at the edge with TypeScript.
Netlify Forms
HTML-based form handling — add a netlify attribute to any form and submissions are captured, emailed, and accessible via API. No backend required.
Netlify Identity
Drop-in auth with email/password, magic links, and OAuth providers — JWT-based identity management with role-based access control for gated content.
Build hooks & webhooks
Trigger rebuilds from any CMS, webhook, or cron job. Combine with ISR-like patterns for dynamic content that updates without full rebuilds.
Why it's hard
Build time limitations
Netlify builds have time limits (15 minutes on free, 30 on Pro). Large sites with thousands of pages can hit these limits. Incremental builds and on-demand builders help, but very large sites may need architectural changes.
Serverless function constraints
Netlify Functions have a 10-second timeout (26 seconds on Pro), 1024MB memory limit, and are synchronous by default. Background Functions extend to 15 minutes but have different invocation patterns. Complex backends may outgrow these limits.
Framework-specific feature gaps
While Netlify supports many frameworks, some framework features (like Next.js ISR or SvelteKit streaming) work differently or have limitations compared to their native platforms (Vercel, Cloudflare).
Vendor lock-in with Netlify-specific features
Netlify Forms, Identity, and Build Plugins are proprietary. Using them heavily makes migration harder. Evaluate whether the convenience justifies the coupling for your specific use case.
Best practices
Use branch deploys and deploy previews
Configure branch deploys for staging environments and deploy previews for every PR. Share preview URLs with stakeholders for visual review before merging. Enable Netlify's deploy notifications in Slack.
Leverage edge functions for personalization
Use Netlify Edge Functions for geo-based redirects, A/B testing, authentication checks, and response transforms. They run at the edge with Deno — TypeScript, fast cold starts, and access to request geo data.
Cache aggressively with proper headers
Netlify's CDN respects Cache-Control headers. Set long cache times for static assets with hashed filenames, and shorter TTLs for HTML pages. Use Netlify's cache purge API for instant invalidation when content changes.
Use build plugins for optimization
Netlify Build Plugins automate tasks — lighthouse audits, image optimization, sitemap generation, and cache prewarming run as part of your build pipeline without custom CI scripts.
