Free Cloud Zone

Your casual guide to free(ish) cloud goodies. Build, ship, and learn without dropping cash upfront.

Hey there, fellow builder! If you're a dev tinkering with side projects, learning new stacks, or just trying to ship something without paying upfront, welcome! This spot rounds up the best free and free-tier offerings from cloud providers. We're talking compute power, storage, databases, auth tools, and more – all with zero or super-low cost to get started.

A quick heads-up: "Free" usually means limits (sleeping apps, bandwidth caps, or time-bound credits), and things change (looking at you, Heroku 2022 vibes). Always pop over to the official links for the freshest details – we've included them right in the tables so you can click through easily.

Frequently Asked Questions

Quick answers to common questions about free cloud tiers.

What is the best free tier for React apps?
Vercel and Netlify are the best free tiers for React apps. Vercel offers 100GB bandwidth/month and automatic deployments from Git. Netlify provides 100GB bandwidth, 300 build minutes/month, and serverless functions. Both support React out of the box with zero configuration.
What's the best free database for side projects?
Supabase offers the best free database for side projects with 500MB PostgreSQL storage, unlimited API requests, real-time subscriptions, and built-in authentication - all free forever. Alternatives include Neon (serverless PostgreSQL, 0.5GB storage) and PlanetScale (MySQL, 5GB read/write).
Are free tiers really free?
Most free tiers are free indefinitely with usage limits. Examples: Vercel's Hobby tier, Netlify's Free tier, and Supabase's Free tier are free forever. Others like AWS (12 months) and Azure ($200 credit for 30 days) are temporary. Always check the provider's pricing page for current limits.
What happens if I exceed free tier limits?
It depends on the provider. Some will charge you automatically (Railway, Render), others will suspend your service (Heroku eco, some AWS services), and a few will throttle performance (Cloudflare Workers). Always set up usage alerts and understand the overage policy before deploying.
What are the best Heroku alternatives?
Top Heroku alternatives with free tiers: 1) Railway - $5 free credit, supports Docker & Git deployments, 2) Render - Free web services with 750 hours/month, 3) Fly.io - Free allowance for small apps, 4) Platform.sh - No free tier but $10 trial, 5) Qoddi - Free tier available. All support popular languages and Git-based deployments.
