We Deployed the Same App to 7 Free Hosts — Here's How They Actually Held Up

Every free hosting provider has a gorgeous landing page and a one-click demo that works flawlessly. That tells you nothing. What you actually want to know is: what happens three weeks in, when traffic trickles in, the instance has been idle, and someone in Chicago clicks your link at 7 a.m.?

So we ran the test. We built one small demo app — a lightweight Node.js API with a Postgres database and a static frontend — and deployed identical copies to seven popular free options. Then we monitored uptime with a third-party checker, measured cold-start and response times from a US East Coast connection, and lived with each one for several weeks.

A quick honesty note: these numbers are from our own testing and will vary with your region and app. Treat them as directional, not gospel.

The Contenders

1. Vercel (Hobby plan)
2. Netlify (Free tier)
3. Cloudflare Pages/Workers (Free tier)
4. Render (Free web services)
5. Railway (Trial credit)
6. Fly.io (Free allowances)
7. Oracle Cloud Always Free (VM)

How They Stacked Up

Cloudflare Pages — The Reliability Monster

Uptime during our monitoring window: effectively 100%. Cold starts were barely noticeable thanks to Cloudflare's edge network, and bandwidth was a non-issue. The trade-off is a steeper learning curve if you're doing anything beyond static assets plus Workers. If raw reliability per dollar (zero dollars, for the record) is your metric, this is the one to beat.

Vercel — Best Developer Experience

Deployments were the fastest and smoothest of the bunch, and preview builds for every pull request are genuinely delightful. Response times from the US East were consistently under 100ms for cached content. The catch: the free tier is metered, and heavy usage nudges you toward Pro. Great for portfolios; watch the dashboard if your project gets traction.

Netlify — Close Second for Static Work

Netlify's free tier performed nearly identically to Vercel in our tests — similar speeds, similar uptime, similarly pleasant workflow. Its generous free build minutes and form-handling features give it an edge for marketing sites and landing pages. Full-stack support feels like an afterthought compared to the leaders.

Render — Best Free Full-Stack Option

The only mainstream provider that'll run a backend and database on a true $0 tier. The database held up fine over our test month. The web service, though, sleeps after 15 minutes of inactivity, and our measured cold starts ran 25–50 seconds. Uptime when awake was solid. If your side project can tolerate a sleepy first visitor, this is the most generous full-stack freebie around.

Fly.io — Solid, Slightly Fiddly

Fly's free allowances let you run small VMs close to your users, and our US-region deployment responded quickly once warm. The setup process assumes more comfort with the terminal than Vercel or Netlify. We also hit occasional deploy hiccups that required a retry. Good for tinkerers who want real VMs without a bill.

Railway — Fast, But the Clock Is Ticking

Railway's performance was excellent — arguably the best raw speed of the managed platforms. But its free trial credit is one-time, not recurring. Once it's gone, it's gone. We're ranking it on merit, but know that this is a 'free trial with great UX,' not free hosting in the forever sense.

Oracle Cloud Always Free — The Power User's Cheat Code

An actual VM, always free, with a decent monthly bandwidth allowance. Our instance stayed up the entire test period, and running your own box means no sleep timers and no artificial limits. The downsides: you're the sysadmin, signup involves a credit card for verification, and capacity in popular US regions can be hard to grab. For a Discord bot or a homelab-style project, nothing else on this list compares.

The Verdict: Which One Should You Use?

• Portfolio or personal site: Vercel or Netlify. Pick whichever workflow you like; both are excellent.
• Traffic-heavy static site: Cloudflare Pages, and it isn't close.
• Full-stack app on a $0 budget: Render, with eyes open about cold starts.
• Discord bot or always-on service: Oracle Cloud's Always Free VM. Bots need to stay awake, and sleeping free tiers will break them.
• Quick experiment with an expiration date: Railway, while your credit lasts.

The meta-lesson from a month of testing: reliability on free tiers tracks with how well your project fits the platform's model. Static on Cloudflare? Bulletproof. Always-on API on a sleeping instance? Frustration guaranteed. Match the host to the workload, and 'free' stops feeling like a compromise.
