Free Postgres Databases

Summary

Fly.io announces that Postgres is now available at no cost for small projects, addressing the storage cost that has kept persistent data out of its existing free tier. The offering adds 3GB of persistent volume space through LVM block devices as small as 1GB, alongside the free VM and RAM allowance. Production deployments use intentional two-node Postgres clusters with data on two isolated NVMe drives and volume snapshots, while a free setup begins as a single Development node and becomes a leader-replica cluster when scaled. The volumes are not limited to Postgres: applications can mount up to 3GB for SQLite or other uses. A credit card is still required for free services, which the post says helps deter cryptocurrency-mining abuse of free VMs.

Takeaways

1. 1

   The free Postgres offering provides 3GB of persistent volume space through LVM block devices as small as 1GB.

2. 2

   Production deployments use two-node Postgres clusters with data redundancy across two isolated NVMe drives and volume snapshots.

3. 3

   The free volumes can also support SQLite or other uses, and a credit card remains required to deter cryptocurrency-mining abuse.
