Carrd vs Fly.io
Pricing
Carrd: Free, Pro from $19/year
Fly.io: Free tier (3 shared VMs), usage-based from $1.94/mo per VM
Description
Carrd: Simple one-page websites for anything
Fly.io: Deploy Docker containers to servers around the world with a single command
Pros
- Dead simple to use
- Incredibly affordable
- No coding required
- Run your app in 30+ regions close to users: real global distribution, not just CDN caching
- Free tier includes 3 shared-cpu VMs with 256MB RAM each, enough for small apps
- Built-in Postgres, Redis, and object storage so you can run a full stack
Cons
- Limited to one-page sites
- Less customization than full builders
- Steeper learning curve than Railway or Render: you need to understand Dockerfiles and fly.toml config
- Billing can be unpredictable: outbound bandwidth costs and machine scaling add up
- Support response times on free tier are slow: community forum only
Details
Carrd lets you build simple, responsive one-page sites in minutes. Perfect for landing pages, portfolios, and link-in-bio pages.
Built by solo founder AJ, bootstrapped to $1.5M ARR with over 3.3M sites created. The definition of doing one thing well.
Fly.io takes your Docker container and runs it on servers around the world. Your app in Tokyo, Sao Paulo, and Amsterdam simultaneously, not behind a CDN, but actually running there. For apps where latency matters (real-time features, APIs, databases), this is the real deal.
The free tier gives you 3 shared VMs with 256MB RAM each, which can run a small app and a Postgres database. Beyond that, pricing is usage-based starting at $1.94/month for a shared-cpu VM. The tradeoff versus Railway or Render is complexity: Fly gives you more control over where your code runs, but you need to understand containers, config files, and networking basics. If you just want to push code and forget about it, Railway is easier. If you want your API to respond in under 50ms for users worldwide, Fly.io is worth the setup.
