Verdict

Best for small always-on APIs, background workers, and microservices that need a free instance without cold starts or spin-down timers.

Use Cases

Host a small REST API backend that needs to stay running 24/7 without cold starts

Deploy a background worker that processes webhooks or cron jobs on a schedule

Run a lightweight containerized microservice alongside other free-tier tools

Free Tier

1 free instance: 512MB RAM, 0.1 vCPU, 2GB SSD, 100GB bandwidth/month, no credit card required

How to Maximize the Free Tier

Koyeb's free instance is always-on (no cold starts or sleep timers), making it ideal for small APIs and background workers that need to stay responsive. Deploy via GitHub for automatic CI/CD. The 0.1 vCPU is shared and low-power, so avoid CPU-intensive workloads — use it for lightweight Node.js/Python APIs, static site serving, or webhook receivers. The 100GB monthly bandwidth is generous. Combine with the free Postgres tier (5 hours/month compute, 1GB storage) for a full-stack setup. One free instance per organization, so team accounts share the limit.

Getting Started

Sign up at koyeb.com (GitHub, GitLab, or email) → connect a Git repository or choose a Docker template → select a region (US, EU, or Asia) → configure environment variables and build settings → deploy — Koyeb builds and runs your app automatically → add a custom domain or use the provided .koyeb.app subdomain.

Pros

Always-on free tier: Free instances don't spin down or sleep — your API stays responsive 24/7 without cron-based wake-up hacks
Multi-runtime: Supports Docker containers, Node.js, Python, Go, Rust, and any language with a Dockerfile — more flexible than single-runtime platforms
Global regions: Deploy to US, EU, or Asia regions on the free tier with automatic HTTPS and private networking between services

Cons

Low CPU: Free instance offers only 0.1 vCPU shared — not suitable for CPU-bound workloads or anything beyond lightweight APIs
Single instance limit: Only one free instance per organization — team projects or multiple services require paid plans
Postgres expiration: Free Postgres database expires after 90 days and must be recreated — not suitable for persistent data without a paid plan
