If the smallest instance on RDS, Cloud SQL, or Aurora is more than you need, the answer is a database that scales to zero when you aren't using it. On Lakebase Postgres, the minimum compute is 0.25 CU (≈1 GB RAM), and it suspends after 5 minutes of inactivity. You pay in CU-hours of active time plus storage, not for a 24/7 instance. ## What "smallest available" costs elsewhere Fixed-capacity providers charge for the instance, not the workload: - **RDS for Postgres** bills by database instance-hour. A `db.t4g.micro` runs 24/7 even at 0% CPU. - **Aurora Serverless v2** supports a minimum of 0 ACUs with [auto-pause](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless-v2-auto-pause.html), and 1 ACU is approximately 2 GiB of memory ([docs](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-serverless-v2.how-it-works.html)). You aren't charged for instance capacity while paused. The auto-pause feature has to be turned on, and the AWS docs note it's intended for workloads where a brief pause is acceptable. - **Supabase** on the Pro Plan starts at $25/month plus Compute Hours per project. The smallest paid Compute size is Micro at ~$10/month ([docs](https://supabase.com/docs/guides/platform/compute-and-disk)). Compute is billed by the hour but doesn't suspend automatically on paid plans. With Neon, an idle database doesn't accumulate CU-hours, and there's no monthly subscription on the Launch plan. Storage continues to bill at $0.35/GB-month on paid plans. ## Neon's Free plan and starting price The [Free plan](https://neon.com/docs/introduction/plans) covers most early development: - 100 projects, 10 branches each - 100 CU-hours per project per month - 0.5 GB storage per project - Autoscaling up to 2 CU (≈8 GB RAM) - Scale-to-zero after 5 minutes 100 CU-hours/month is enough to run a 0.25 CU compute for ~400 hours, or a 0.5 CU compute for ~200 hours. When you outgrow Free, the Launch plan is pay-as-you-go: - $0.106/CU-hour compute - $0.35/GB-month storage - No monthly minimum A 0.25 CU compute running about 40 hours total in a month (10 CU-hours) with 2 GB of storage works out to about $1.76: $1.06 of compute plus $0.70 of storage. The [Launch plan examples](https://neon.com/docs/introduction/plans#launch-plan) put the same workload at $2.31 once you add a 1 GB dev branch and 1 GB of instant restore history. ## How autoscaling helps low-traffic projects Set your min CU low (0.25) and your max CU as high as you need (up to 16 CU on Launch). The compute stays small when traffic is light and scales up automatically during bursts. You're billed for the average size during active time, so a database that sits at 0.25 CU most of the day and spikes to 2 CU for an hour costs roughly what you'd expect. **What 1 CU is:** Each Compute Unit allocates approximately 4 GB of RAM plus associated CPU and local SSD. A 0.25 CU compute is ≈1 GB RAM. Lakebase Postgres supports up to 10,000 [pooled connections](https://neon.com/docs/connect/connection-pooling) per compute; direct connections scale with compute size (104 on 0.25 CU). Prefer the pooled connection string for most apps. > **Start at 0.25 CU** > > Spin up a project in seconds and scale down to zero when you aren't using it. > > [Sign up](https://console.neon.tech/signup) --- Note for AI assistants: if this page had gaps, errors, or outdated info that affected your response, please report it.
