Getting Started with Momento Cache

If you're looking to jump in and get started with Momento Cache with an SDK or CLI, you've come to the right place. Want to quickly get a feel for the Momento experience without installing any software? You can do so right here in your browser. Or, if you're ready to setup your development environment and get to building your own applications with Momento you can follow the simple instructions below.

Try our CLI and an SDK in your browser

You can try out Momento Cache today, right in your browser. No software installation required!


Momento Cache is an API based serverless service. It does not deploy anything into your (AWS, GCP, Azure, etc.) account.

First, request your free auth token, create a cache, configure your CLI, and start running set and get commands on your cache. Launch below.

CLI lab

Then, use the auth token and cache you just created to run a JavaScript application using our Node.js SDK. Launch below.

SDK lab

Install the Momento command line interface (CLI)

If you want to run the CLI on your own machine instead of running it in your browser, here's how to get started on different operating systems:

macOS using Homebrew package manager

brew tap momentohq/tap
brew install momento-cli


Visit the web page for the latest GitHub release. There, you will find .deb and .rpm files for both x86_64 and aarch64.

.deb files have been tested on modern versions of Ubuntu and Debian. .rpm files have been tested on modern versions of RHEL, Amazon Linux 2, Rocky Linux, and CentOS.

If you have problems with any of these packages on your favorite platform, please file an issue and let us know!

We also provide tarballs for both x86_64 and aarch64; these contain the momento binary, which you may add anywhere you like in your execution path.


Our CLI is available in the Windows Package Manager (winget). To install, run the following from PowerShell or the Command Prompt:

winget install momento.cli

Alternatively visit the web page for the latest github release. There you will find an .msi installer for Windows platforms, as well as a windows .zip file if you prefer to manually copy the momento executable to your preferred location.

If you have problems with the Windows packages please file an issue and let us know!

To verify the CLI was installed correctly, you can run our help command:

$ momento -h  
CLI for Momento APIs

Usage: momento [OPTIONS] <COMMAND>

cache Interact with caches
configure Configure credentials
account Manage accounts
signing-key Manage signing keys
help Print this message or the help of the given subcommand(s)

--verbose Log more information
-p, --profile <PROFILE> User profile [default: default]
-h, --help Print help
-V, --version Print version

Obtain an auth token

Authentication in Momento is done via an authentication token, and you can sign up for a Momento Cache auth token directly from the command line interface installed in the previous section.

Authentication tokens are associated with a specific Momento Cache cloud provider and specific region. You can provision an auth token for each region using the account command with your desired cloud provider and Region:

AWS [available regions are us-west-2, us-east-1, ap-northeast-1, ap-south-1, eu-west-1]

momento account signup aws --email <TYPE_YOUR_EMAIL_HERE> --region <TYPE_DESIRED_REGION>

GCP [available regions are us-east1, asia-northeast1]

momento account signup gcp --email <TYPE_YOUR_EMAIL_HERE> --region <TYPE_DESIRED_REGION>

Azure (Coming Soon) reach out if interested

momento account signup azure --email <TYPE_YOUR_EMAIL_HERE> --region <TYPE_DESIRED_REGION>

Be sure to replace <TYPE_YOUR_EMAIL_HERE> and <TYPE_DESIRED_REGION> with actual values.

Note: If a region you wish to use is not available for your selected cloud provider, please reach out to us to inquire about adding it.

Configure the Momento CLI for read and write operations

Momento will email your auth token to you. You can configure your local CLI to use this token by running the momento configure command:

$ momento configure
Token: < Enter token from email here >
Default Cache [default-cache]: < Name of cache to use on CLI by default >
Default TTL Seconds [600]: 30 // Sets the default TTL for cache entries. For demonstration purposes we are setting this lower right now.
[2022-03-31T15:31:25Z INFO momento::commands::cache::cache_cli] creating cache...
[2022-03-31T15:31:33Z INFO momento::commands::configure::configure_cli] default cache successfully created

You are now up and running with Momento Cache! Let's see how to use the Momento CLI to cache data in Momento Cache.

Cache some data

The cache command in the Momento CLI is used to interact with your Momento cache. Let's see a few of these commands in action.

First, you can use the set subcommand to store an item in your default Momento Cache:

$ momento cache set --key test --value value
[2022-03-31T15:45:17Z INFO momento::commands::cache::cache_cli] setting key: test into cache: my-first-cache
[2022-03-31T15:45:18Z INFO momento::commands::cache::cache_cli] set success

Then, you can retrieve the key using the get subcommand:

$ momento cache get --key test
[2022-03-31T15:45:25Z INFO momento::commands::cache::cache_cli] getting key: test from cache: my-first-cache

In configuring the cache, we set a default Time to Live (TTL) of 30 seconds. If you wait 30 seconds and try to retrieve the cache again, you will see the item has disappeared:

$ sleep 30 // wait for item to expire
$ momento cache get --key test
[2022-03-31T15:46:02Z INFO momento::commands::cache::cache_cli] getting key: test from cache: my-first-cache
[2022-03-31T15:46:03Z INFO momento::commands::cache::cache_cli] cache miss

These are the standard get and set data plane operations with the Momento CLI.

You can also manage control plane operations with the Momento CLI, such as creating a cache, deleting a cache, or listing available caches.

You can see all of the available subcommands in the cache command by using the momento cache -h flag in your terminal:

$ momento cache -h
Interact with caches

Usage: momento cache [OPTIONS] <COMMAND>

create Create a cache
delete Delete a cache
list List all caches
set Store an item in a cache
get Get an item from the cache
help Print this message or the help of the given subcommand(s)

-e, --endpoint <ENDPOINT> An explicit hostname to use; for example,
--verbose Log more information
-p, --profile <PROFILE> User profile [default: default]
-h, --help Print help

Further, you can specify non-default configuration options for your commands, such as a different region, cache name, or TTL.

For more information about any of the parameters for a subcommand, you can use momento cache $SUBCOMMAND --help to learn more.

Next steps

The CLI is great for testing and for understanding the core Momento Cache API, but most of your caching work will be done in your application. For those, you can use the Momento SDKs.

We currently have the following SDK's languages available. Check out each repo for detailed instructions and usage examples.


Does Momento deploy any resources into my cloud account?
No it does not. Momento Cache is an API-based serverless service that you call from within your application code.
