blitz.cloud plan limits - apps, memory, storage and databases

The blitz.cloud free plan allows up to 15 apps, 2 GB of reserved memory shared across them, 10 GB of storage and one managed database, with database backups kept for 7 nights. Apps never go to sleep. Pro raises these limits, but it is not on sale yet.

Plan limits

Hitting a limit blocks that one action, with a sentence naming the limit and what would free up room. Apps that are already running are never stopped because of it.

How memory is counted

The 2 GB pool counts memory that is reserved, not memory that is in use. Each app reserves a fixed amount depending on its size, and may use more than that up to its own ceiling when the server has room.

Apps from Docker images always use the small size. App Store apps use the size their entry says, and today only n8n is medium. You can't pick a size yourself.

Databases reserve memory from the same pool:

So 15 small apps fill the 2 GB pool on their own (15 x 128 MB = 1.92 GB). An app plus a PostgreSQL database takes 256 MB.

How storage is counted

Storage also counts reservations. A Docker image with kept folders reserves 1 GB, an App Store app reserves between 1 and 5 GB, and databases reserve as listed above. Nextcloud and its MariaDB together reserve 6 of the free plan's 10 GB.

The meters in Settings use decimal units, which is why the memory pool can read as 2.1 GB and storage as 10.7 GB.

What is not limited

• Apps don't sleep or scale to zero when nobody visits. They keep running until you pause them.
• There's no bandwidth quota and no request counter today.
• There's no build minutes limit, because there are no builds yet.

What is blocked

• Outgoing mail on ports 25, 465 and 587 is blocked for every app, to stop spam. Use an email API over HTTPS instead.
• Apps can't reach other accounts' apps or databases, the platform's internal services, or private IP ranges.
