Ease of Use
Fly.io is easy to get started but due to its nature (running ephemeral Firecracker VMs on an edge network) you might need to make slight changes to your application to make it work on Fly.io.
On the other hand, Cloud 66 deploys your apps and databases on your own servers, so you don't need to make any changes to your application to make it work on Cloud 66.
Both Cloud 66 and Fly.io have detailed and well-written documentation, making it easy to get started and deploy your applications.

Flexibility
Flexibility and control is where Cloud 66 shines. Running your applications on your own servers, means there is not a single platform to build for all Cloud 66 users. This gives you great flexibility in many ways compared to Fly.io.
HTTP Response Time
Fly.io HTTP response time is limited to 60 seconds, while Cloud 66 has no such limitation. This means you can run long-running tasks on your own servers, which is not possible on Fly.io
Long running processes
Fly.io does not support long running processes, so you cannot run background jobs or cron jobs on Fly.io. Cloud 66 supports long running processes, so you can run background jobs or cron jobs on your servers.
Custom Packages
Fly.io does not allow you to install custom packages on your servers or Contribs on components like Postgres. There is no such restrictions on Cloud 66, so you can install any package or Contrib you want.
Managed Databases
Fly.io offers managed Postgres and SQLite (Redis is provided via a third-party, purchased separately). Cloud 66 offers managed MySQL, Postgres, MongoDB, Redis, Elasticsearch and InfluxDB as well as support for connecting to your cloud provider's managed database like RDS.
Fly.io takes daily snapshots of Postgres. Cloud 66 backups are configurable and can be taken as often as every 1 minute and be kept for as long as you want.
Cloud 66 takes synchronized backups across all your databases like Postgres and Redis, so you can restore your entire stack to a previous state with a single click.
SSH Access
Fly.io does not provide SSH access to your servers. Cloud 66 provides SSH access to your servers, so you can debug and troubleshoot your applications or run commands on your servers.

Price
Fly.io is priced by the time a request is served, while Cloud 66 is priced by the size of your servers.
Comparing Fly.io pricing to Cloud 66 pricing is not straightforward, as Fly.io does not provide servers, and a lot of the cost depends on the type of Firecracker VMs you use on Fly.io.
While Cloud 66 email support is free, Fly.io charges $29/month for email support.
All VMs created by Cloud 66 come with a large amount of SSD storage, while Fly.io charges $0.15/GB/month for persistent storage.
