Verdict

Best for edge-first JavaScript/TypeScript APIs and apps that need sub-millisecond cold starts and built-in key-value storage.

Use Cases

Deploy a real-time API backend with Deno KV for session storage and caching

Build an edge-rendered Fresh web app with server-side rendering and zero cold starts

Host a lightweight webhook relay that processes incoming events from third-party services

Free Tier

1M requests/month, 20GB bandwidth, 1GB KV storage, custom domains, no credit card required

How to Maximize the Free Tier

Deno Deploy's free tier is generous for edge apps — 1M monthly requests and 20GB egress cover most side projects comfortably. Use Deno KV (1GB included) as a lightweight database to avoid needing a separate service. Deploy via GitHub integration for automatic deploys on push. Keep an eye on egress since inbound request data doesn't count but response payloads do. For high-traffic API endpoints, combine with caching headers to reduce bandwidth. The free tier doesn't include custom domains with SSL — use the deno.dev subdomain for zero-config HTTPS.

Getting Started

Sign up at deno.com/deploy (GitHub, Google, or email) → connect a GitHub repo or import a fresh project → Deno auto-detects your framework → deploy pushes to production instantly → add KV database in the dashboard → configure custom domain in project settings.

Pros

Cold starts: Sub-millisecond cold starts thanks to the V8 isolate architecture — dramatically faster than Lambda-style functions
Built-in KV: Deno KV provides a globally distributed key-value store with no additional setup or separate service needed
Native TypeScript: First-class TypeScript support with no build step — deploy .ts files directly with Deno runtime features like permissions and web standard APIs

Cons

Ecosystem: Smaller ecosystem compared to Node.js — some npm packages may need compatibility shims or don't work at all
Vendor lock-in: Heavy use of Deno-specific APIs (KV, Deploy-specific APIs) makes migration to other platforms harder
Runtime limits: Free tier restricted to Deno runtime only — can't run Node.js, Python, or other runtimes on Deploy
