前言#
在部署一些开源项目的时候，经常会遇到需要数据库的场合，但是由于机器本身的配置就不高，因此寻找第三方的数据库服务是一个更好的选择，在寻找的过程中发现很多平台都提供了免费额度的数据库服务，本文就是对这些平台做一个整理。
PostgreSQL#
Supabase#
官网#
免费套餐#
- Unlimited API requests
- 500 MB Database Size
- 5GB Bandwidth

Neon#
官网#
免费套餐#
- One Neon project with up to 10 branches.
- 3 GiB of storage per branch.
- Unlimited Postgres databases
- A shared compute with 1 GB of RAM for each branch.
- 100 hours of Active time per month, affecting non-primary branch compute usage only. Active time on all computes is counted toward the limit, but when the limit is exceeded, only non-primary branch computes are subject to suspension. Your primary branch compute always remains available regardless of the limit, ensuring that access to data on your primary branch is never interrupted. You can monitor Active time on the Usage widget on the Neon Dashboard. The Active time limit resets at the beginning of each month. For instance, if you enroll in the Neon Free Tier in the middle of the month, say on January 15th, your Active time limit will reset on February 1st, the first day of the following month.
- A point-in-time restore window of 7 days of reasonable usage.
