Supabase Postgres
Supabase offers managed Postgres databases on Fly.io infrastructure. Provisioning Supabase on Fly.io ensures low-latency database access from applications hosted on Fly.io.
This service is in public alpha. Here’s what you should know.
Supabase Databases run on single machines and are susceptible to hardware issues. Restoring an affected database may require contacting support.
During the alpha, you won’t be charged for usage, but your usage will show up as a preview on your Fly.io bill.
Most Supabase features besides raw Postgres are not enabled yet, such as auth or storage.
Supabase’s connection pooler runs on AWS infrastructure, so using it may add connection latency depending on your region’s proximity to AWS servers.
Create and manage a Supabase Postgres database
Creating and managing databases happens exclusively via the Fly CLI. Install it, then signup for a Fly account.
Running the following command in a Fly.io app context – inside an app directory or specifying -a yourapp – will automatically pick a region and set secrets on your app.
flyctl ext supabase create
? Select Organization: soupedup (soupedup)
? Choose a name, use the default, or leave blank to generate one:
? Choose the primary region (can't be changed later) Miami, Florida (US) (mia)
Your Supabase database (icy-wind-1879) in mia is ready.
Set one or more of the following secrets on your target app.
DATABASE_URL: postgres://postgres:password@db.kworhjwentroqhegh.supabase.co:5432/postgres?sslmode=disable
DATABASE_POOLER_URL: postgres://postgres.kworhjwentroqhegh@password@fly-0-mia.pooler.supabase.com:6543/postgres
DATABASE_URL offers a direct IPv6 connection to your database. Use this URL from your Fly.io applications.
DATABASE_POOLER_URL runs connections through a connection pooler. Currently, the connection pooler runs outside of Fly.io and may introduce connection latency. Use this URL to test connection pooling behavior, or to connect from locations that don’t support IPv6, like many household ISPs.
Pricing and Billing
To test more than one database, or to test Supabase addons, you must upgrade your Supabase organization to the Supabase Pro Plan. Use flyctl ext supabase dashboard --org yourorg to sign in and upgrade.
Supabase offers one free, resource-limited database per Fly.io user. After that, all databases are billed on pay-as-you-go basis under the Supabase Pro plan. Check the official Supabase Pricing page for details.
While you won’t be charged during alpha, database usage and Supabase plan fees will show up on your monthly Fly.io bill. You can track database usage details in the Supabase web console.
