Serverless is about simplicity in every dimension. From zero backend management to only paying for what you use, everything about the modern cloud environment should make developers’ lives easier. We’ve seen this come to life for many aspects of application architecture with Amazon DynamoDB, Amazon S3, Google Cloud Firestore, Azure Cosmos DB, and more—but solutions for the caching layer have been just so-called serverless, at best. Caches are still plagued by manual processes and costly overprovisioning, breaking the serverless promise. Momento is different: a caching service that meets every serverless criteria—including a simple pricing model.
Momento costs $0.15 per GB transferred. That's it. Your first 50 GB are free each month—and you don't even need a credit card to get started.
What’s the catch? There isn’t one. We literally only charge you for data transferred into and out of Momento. Everything else is included.
Examples because we’re serious
Below are some hypotheticals with real math to illustrate how easy it can be to estimate costs when pricing is this simple. If you need extra help—or simply can’t believe it—join our Discord and drop us a message. We’ll get it sorted out. Take the Momento challenge and see how much you can save!
Example 1
You process a total of 1 million read/write requests per day with average object sizes of 4KB. Momento would cost you:

The free 50 GB/month reduces the cost of this workflow by $7.50/month—down from $18.30/month.
Example 2
You process an average load of 5K RPS with 1KB objects. Momento would cost you:

The free 50 GB/month reduces the cost of this workflow by $7.50/month—down from $1,976.40/month.
Example 3
You have a 20 RPS Lambda that caches 1KB objects. Momento would cost you:

The free 50 GB/month reduces the cost of this workflow by $7.50/month—down from $7.91/month.
Questions because you’re skeptical
Is it really just $0.15/GB transferred in and out of Momento? What else do you charge for?
Yes, it really is just $0.15. There are no hidden charges. There’s not even a separate storage fee to worry about. For extra peace of mind, here’s a table with a detailed breakdown of everything you don’t have to pay for with Momento.

Can I run a production app for free on Momento?
Yep! Our free tier and low usage tiers are exactly as fast, as available, and as secure as our at-scale service. You get all our availability features like multi-AZ replication, hot key protection, and automatic scaling to handle bursts. You even get all our security features for free: end-to-end encryption, per-request authentication, and transport layer security (TLS).
We frequently find customers provisioning an entire cluster to handle low-RPS workflows. If you want them to be highly available, you need multiple nodes. If you believe in continuous integration and continuous delivery (CICD), you likely have a similarly sized cluster in staging—and maybe even in dev. That adds up! Turn off those machines—and save the environment. Go Momento!
Can I run a production app for $1.50/month on Momento?
Absolutely! Say you’re transferring 60 GB of data into and out of Momento each month. You get the first 50GB free, which renews monthly. That means you’d end up only paying $0.15/GB for the remaining 10GB—coming out to $1.50 per month.
As crazy as it may sound to offer enterprise-grade availability, security, and performance at any scale for any budget, we’re not the first to do this—we’re just the first to bring it to caching! You can experience this with other serverless services like Amazon DynamoDB, AWS Lambda, MongoDB Atlas, Google Cloud Functions, and the list goes on.
Is there a default limit?
Yes and no. “Limit” is a strong term. There’s a default 100 RPS limit on each cache, but don’t let that stop you. Want to go to 1 million or 10 million RPS? Just give us a holler on our Discord.
Will it scale?
Hell yes! Momento makes your caching future-proof. You can add Momento *extremely* quickly—in five minutes or less with just five lines of code, actually—and then it just fades into the background, no matter the load. You just pay for what you use, meaning you get a scalable cache without spending a lot of cash.
Will it blend?
That depends. Momento is robust with enterprise-grade security and availability, so we do not recommend putting it in a blender as it may void the warranty of the blender. However! Momento does blend seamlessly with your current cloud setup, whether you're on AWS, GCP, Azure, or multi-cloud!
A simple conclusion
We’ve said it before (well, Meera said it), and we’ll say it again: stop settling for almost serverless. It’s time to bring caching up to the same serverless standard as the rest of the stack. No more overprovisioning—and no more math gymnastics.
Using Momento Serverless Cache is just as simple as our pricing. Go ahead and get started with us directly—or check us out on AWS Marketplace!
