For beginners, learning how to deploy a Deno app takes minutes: sign into console.deno.com, connect a GitHub repository or use the CLI, and get a live URL — at no cost. The Deno Deploy free tier provides a generous $0/month starting point for your projects.
How This Guide Was Built
This review is based on official documentation, pricing pages, and community reports — we did not run the tool hands-on. We verified all claims against the Deno Deploy pricing page and the official Deno Deploy getting started guide at docs.deno.com. Last verified: August 2026.
How do I deploy a Deno app for beginners?
The simplest method is signing in at console.deno.com, creating an organization, connecting your GitHub repository for automatic deployments, or using the deno deploy CLI command. Your project will be assigned a live URL ending in *.deno.net, and the entire process costs $0. This workflow is detailed in the official Deno Deploy getting started guide.
What the Deno Deploy free tier includes
The free tier provides one million requests, 20 GB of egress, and 15 CPU-hours monthly per organization, plus 20 apps and a 1 GiB KV database, according to the Deno Deploy pricing page.
| Fact | Limit |
|---|---|
| Requests | 1,000,000/mo |
| Egress | 20 GB/mo |
| CPU-hours | 15/mo |
| Memory | 350 GB-h |
| Apps | 20 |
| Deployments | 60/hr |
| Team members | 5 |
| Custom domains | 50/org (no wildcards) |
| Volume storage | 1 GiB |
| KV storage | 1 GiB |
| KV reads | 450,000/mo |
| KV writes | 300,000/mo |
| KV regions | 1 |
| Logs retention | 1 day |
| Analytics | 30-day trailing |
For comparison, the Pro plan costs $20/month and includes 5 million requests, 200 GB egress, wildcard domains, and email support, with overage billed at $2 per million requests.
Getting started: your first Deno Deploy app
Begin by visiting console.deno.com, signing in, and creating an organization with a permanent slug. Connect a GitHub repository via the “New App” button, where Deno automatically detects your framework — like Next.js, Astro, or Fresh — and configures the build. For the CLI flow, install Deno, create a main.ts file using Deno.serve(), and run deno deploy as outlined in the CLI tutorial.
Deno KV: a free database for your app
Deno KV is a globally distributed key-value database included in the free tier, which you can provision from your app’s settings and access directly in your code with Deno.openKv() for simple get and set operations, per the KV reference. Note that KV Queues, which use Deno.Kv.enqueue(), are not supported on the free or Pro plans.
Custom domains and regions
You can add up to 50 custom domains per organization on the free tier, each receiving automatic TLS certificates from Let’s Encrypt, as stated in the domains documentation. Deployments run in the “us” and “eu” regions, with “global” serving requests from both locations.
Deploying with the CLI: a worked example
If you prefer the terminal over the dashboard, the CLI flow is just as direct. First install Deno locally with curl -fsSL https://deno.land/install.sh | sh, then create a minimal server file:
// main.ts
Deno.serve((req) => {
const url = new URL(req.url);
return new Response(`Hello from Deno Deploy! Path: ${url.pathname}`, {
headers: { "content-type": "text/plain" },
});
});Run deno deploy --project my-first-app main.ts, authenticate when prompted, and Deno provisions the project, builds the worker, and prints your live https://my-first-app.deno.dev URL in under a minute. The CLI also supports --prod for production deploys and integrates with GitHub Actions via the denoland/deployctl action, per the CLI tutorial. One beginner trap: the CLI’s default output says .deno.dev, but the current default subdomain is .deno.net — either URL routes to the same deployment.
A minimal Deno KV counter app
Deno KV is useful the moment your app needs state, and the free tier’s 1 GiB database is plenty for a hobby project. Here is a complete counter that persists across requests:
const kv = await Deno.openKv();
Deno.serve(async () => {
const res = await kv.get(["visits"]);
const count = (res.value ?? 0) as number + 1;
await kv.set(["visits"], count);
return new Response(`Visits: ${count}`);
});KV operations are strongly consistent by default and work across the global edge without extra configuration, per the KV reference. Watch the free-tier quotas: 450,000 reads and 300,000 writes per month. A small blog or API with modest traffic stays well under those limits, but a chat app polling every request can burn through the write quota in days.
Deno Deploy vs other free tiers
Compared with the Vercel free tier guide and the Cloudflare Pages free tier guide, Deno Deploy’s free plan is competitive on raw quotas — one million requests and 20 GB egress sit between Vercel’s 100 GB-h and Cloudflare’s unlimited egress. Where Deno Deploy stands out is the built-in KV store and the fact that your code runs on the same runtime you use locally, so there is no Node/Deno translation layer. Where it falls short is the ecosystem: Vercel has first-party Next.js integration and Cloudflare has Workers AI and Durable Objects, neither of which has a direct Deno Deploy equivalent. If your stack is TypeScript-first and edge-oriented, Deno Deploy is a strong default; if you need the wider JavaScript ecosystem, the other two are safer.
Free-tier limits: what happens when you exceed them
If your usage exceeds the free tier’s monthly quotas, your applications will be paused until the next billing cycle begins. According to the changelog, there is no billing on the Free plan; you simply have to wait for the cycle to reset or upgrade your plan.
Common beginner mistakes
The most common failures come from following outdated tutorials, per the migration guide. Avoid using the legacy serve() function from std/http, which causes a warmup timeout; use the modern Deno.serve() API instead. Do not visit dash.deno.com, as Deploy Classic was shut down on July 20, 2026. Remember that the default subdomain is *.deno.net, not *.deno.dev. For custom domains, disable proxying on Cloudflare’s _acme-challenge CNAME record. Finally, do not expect Deno KV Queues to work, as Deno.Kv.enqueue() is not supported.
FAQ
Does Deno Deploy have a free tier for beginners?
Yes, the free tier is ideal for beginners, offering a generous $0/month package including one million requests, 20 GB of egress, and 20 apps per organization, with 1 GiB of Deno KV storage and no billing, as detailed on the Deno Deploy pricing page.
Can I use a custom domain on the Deno free tier?
Yes, you can use custom domains on the free tier. The platform allows up to 50 custom domains per organization and provides automatic TLS certificates via Let’s Encrypt for each one, as stated in the domains reference. Wildcard domains are not included on the free plan.
What happens if I go over the free tier limits?
When you exceed the free tier limits, your applications are automatically paused until the next monthly cycle begins, so your site goes offline temporarily rather than generating a bill. The changelog confirms there is no overage billing on the Free plan.
Can I deploy automatically from GitHub on the free tier?
Yes — automatic GitHub integration is included in the free plan. When you connect a repository, Deno Deploy builds on every push to the connected branch, and you can preview pull requests before merging. For finer control, the denoland/deployctl GitHub Action lets you pin a specific entrypoint and pass --prod only on tagged releases, which is the pattern most teams use to keep preview and production deployments separate. Every deployment gets its own URL, and the free tier allows 60 deployments per hour, which is ample for a solo developer pushing several times a day (deployctl docs). Environment variables and secrets are managed in the project settings, so credentials never need to live in your repository, and rollbacks to any prior deployment are one click away.
Where to go next
You now know the essentials of deploying a Deno app for free. For other hosting options, explore our Vercel free tier guide or the Cloudflare Pages free tier guide. If you need more resources, consider upgrading to the Pro plan. Users migrating from the old platform should consult the official migration guide for step-by-step instructions.
