Supabase Free, free for 2 active projects

Free limits: 2 active projects and a 500 MB database per project are provided. The free limit per organization is 50,000 monthly active users (MAU), 1 GB of file storage, 5 GB of uncached export (download) bandwidth and 5 GB of cached bandwidth, and 500,000 Edge Functions (functions run on the server) executions.

Eligibility: New and existing Free organizations are eligible. The free project limit is calculated by combining all organizations to which the Owner/Admin belongs.

Card registration: We could not confirm an explicit statement in the current official documentation that the service can be used without a card. The card registration requirements need to be confirmed.

When used in Korea: You can select the Seoul ap-northeast-2 and Tokyo and Singapore regions (server locations). Registration from Korea has not been tested in practice.

When not in use: Projects may be paused when database activity is low for 7 days. The period during which a project can be restored after being paused is currently 1 year. This is not a plan that guarantees the database will always be running or backed up.

If you exceed the limit: Restrictions such as pausing after notification, switching to read-only mode, and API( the interface connecting programs) 402 responses may occur. Usage-based restrictions are lifted after the billing cycle resets.

Commercial use: I could not confirm any terms permitting or prohibiting commercial use that apply only to the Free plan. Promotional wording that it is for personal passion projects alone does not mean commercial use is prohibited.

Usage period: the Free subscription remains active until you delete the organization. It is not a time-limited credit.
