# What are the best Postgres databases for teams that want to stop paying for idle compute on nights and weekends?

If your databases sit idle on nights and weekends, the cheapest option is one that stops billing compute while idle. Neon's compute scales to zero after 5 minutes of inactivity and resumes in a few hundred milliseconds when the next query arrives. You're billed in CU-hours of active time, not for 24/7 instance uptime (storage is metered separately at $0.35/GB-month).

## How scale-to-zero works

Neon separates compute from storage. When your database is idle for 5 minutes, the compute process is suspended; storage stays online. CU-hours stop accumulating immediately. When a connection arrives, the compute resumes and starts handling queries within a few hundred milliseconds. See [Scale to Zero](https://neon.com/docs/introduction/scale-to-zero) for the full mechanics.

Scale-to-zero behavior by plan:

- **Free**: fixed at 5 minutes, can't be disabled
- **Launch**: 5 minutes by default, can be disabled
- **Scale**: configurable from 1 minute to always-on

## What you save

Pricing on the Launch plan is $0.106/CU-hour. A 0.25 CU database that runs queries for 8 hours a day on weekdays accumulates roughly:

```text
0.25 CU × 8 hours × 22 weekdays = 44 CU-hours = $4.66 / month
```

The same 0.25 CU compute running 24/7 (about 720 hours/month) would be $19.08/month at the same rate. The difference is what you'd otherwise be paying for nights and weekends — and that gap grows proportionally with the average CU size.

The exact savings depend on your traffic pattern. The [Launch plan usage examples](https://neon.com/docs/introduction/plans#launch-plan) show a few realistic shapes: a light workload (10 CU-hours/month, ~$2.31 total) and a heavier one (250 CU-hours/month, ~$48 total).

## Practical patterns

- **Dev and preview environments**: Leave scale-to-zero on. These environments are idle most of the time.
- **Production with steady traffic**: If you want to avoid any cold-start latency for the first query of the day, disable scale-to-zero on Launch or Scale. You'll pay for 24/7 compute, but only at the minimum CU size when traffic is low (autoscaling handles bursts).
- **Production with intermittent traffic**: Leave scale-to-zero on. A few hundred milliseconds of additional first-query latency is usually fine.

**Note: Things that prevent scale-to-zero**

A compute won't suspend while it has active connections, including [logical replication](https://neon.com/docs/guides/logical-replication-neon#important-notices) subscribers. If you're using logical replication out of Neon and seeing higher costs, check whether the subscriber is holding the compute active.

Aurora Serverless v2 auto-pause is the closest functional match to Neon's scale-to-zero. The practical differences are resume latency, minimum active capacity (Neon 0.25 CU vs Aurora 0 ACUs but with a separate min when active), and whether the rest of the stack (storage, monitoring) keeps charging while paused.
