Create Database
The old way
Pay for the compute you provisioned
Traditionally, you provisioned databases by compute and ram. You pay even when usageis low. You’re also often stuck with what you provisioned, even when demand increases.
The bit.io way
Pay for the row operations you actually do
With always-available minimum performance and budgeted monthly burst capacity
row operation
(RO) is a logical read, write, update, or delete of a data row
Queries consume row operations from a pool
An always-refilling row operations pool ensures an always-available database
If the pool is empty, the database canstill burst with additional capacity
Works for any budget
and scale
Free databases never shut down when they hit a limit.
Pro databases provide burst capacity to handle extra load.
Free Database
200 row operations per second, always available. 3 DBs for free.
Try bit.io
Pro Database
1000 row operations per second, always available for $5 per month. Autoscale to the capacity you need for $1 per 100M ROs. Set a monthly spend limit to control costs.
Create Pro Database
How many Row Operations do I need?
How many rows of data
will you be querying?
Will those queries use indexes?
(Recommended for production)
How many queries are running
simultaneously per second?
ROs per Second
ROs per Month
Max Cost per Month
This is only an estimate of usage. The particular indexing approach and query patterns may have different actual use.
Upgrade to a paid database without autoscaling. It will have guaranteed capacity and won’t fall over as you approach limits, instead it will just slow down.

How do I control my costs?
Set your monthly burst limit to be within your target budget. Whenever burst usage exceeds that limit and the RO pool is empty, your database will slow down. You’re never be charged above the budget.
Can I turn off my database?
bit.io is a serverless database so there are no “start” or “stop” settings. The $5 base fee pays for storage, the RO pool, and other managed database features like backups, failover, etc.
What are ROs and why bill by them?
A “Row Operation” (RO) is a read, write, update, or delete of one row of data in your database. ROPS (Row Operations Per Seconds) are the number of “Row Operations” done in one second.

ROs represent the logical usage of your data. The less things you do to your data, the less you should pay. On the other hand, compute and RAM are hard to predict/tune in advance so you can leave that to us.
Does my database raise errors when I hit the row operations burst limit?
No, it will just slow down. Because your RO pool is always refilling, your database will perform at the pool fill rate until you either increase the limit or the billing period ends and spend is reset.
What is an RO pool? How does the pool fill?
The row operations pool is an auto-filling reserve of row operations that you consume when doing database operations. If the pool is empty, your database can still burst for an additional fee of $1 per 100M row operations.

The pool fills up automatically with more operations every second -- 200 for Free and 1000 for Pro. And, the pool drains when you perform row operations.

It’s like a gas tank this is always slowly refilling. If you run out of gas, you can choose to drive at the refill rate or pay extra to speed up as required. When you first create the database, you get a full tank of gas, too.
What happens when I hit my monthly RO limit?
When usage exceeds the monthly RO limit you’ve set, your database will slow down to the pool refill rate but never stop or raise errors.
