Deploying Quirrel is straight-forward.

There are three main environment variables you need to specify in your deployment settings:

VariableMeaningWhere to get
QUIRREL_TOKENaccess token for the Quirrel server.Hosted: Create a new Project + Client in the Dashboard. Self-Hosted: Check How to deploy our own server .
QUIRREL_BASE_URLThe base URL of your application's deployment.You probably know this. Something like
QUIRREL_ENCRYPTION_SECRETA 32-character-long secret used for end-to-end encryption of your jobs.Can be generated using openssl rand -hex 16 or

After setting these variables, you can deploy your application and Quirrel should be working. If it doesn't, feel free to reach out.

Cron Jobs

If you're using CronJobs(), make sure to run quirrel ci during the deploy process. Make sure to have QUIRREL_API_URL, a QUIRREL_TOKEN and the QUIRREL_BASE_URL set when executing quirrel ci.

"scripts": { "vercel-build": "npm run build && quirrel ci" }

If you're on Vercel, you can connect QUIRREL_BASE_URL to your VERCEL_URL. Only do this for preview environments, not for production! QUIRREL_BASE_URL is used to determine the deployment that your jobs should be executed on. If you set it to VERCEL_URL, that means all jobs will be executed on the exact deployment that they were created on, excluding them from future bugfixes. To connect QUIRREL_BASE_URL to VERCEL_URL, set its value to @VERCEL_URL (notice the @).

How to deploy your own server

Hosting on Fly

If you're planning to host your Quirrel instance on, you can follow Mokhtar Mial's tutorial:

Self-Hosting Quirrel on

🐉 Here be dragons: Running your own infrastructure isn't the easiest thing in the world, and you should know what you're doing.

Deploy the Image

It's recommended to deploy Quirrel using the Docker Image:

Set the REDIS_URL environment variable to a connection string for your Redis instance. Make sure your Redis instance is persistent.

Set the PASSPHRASES environment variable to some secret passphrase. You can also specify multiple by :-separating them.


Set the REDIS_TLS_CA_BASE64 environment variable to a base64 encoded certificate if your Redis connection requires you to provide a self-signed certificate.

Alternatively set the REDIS_TLS_CA_FILE environment variable to the path of your certificate. You can provide the actual file by either using the official image a base or by using a bind mount.

Acquire a token

Once our server is ready, we'll need to get an auth token:

curl --user ignored:{PASSPHRASE} -X PUT {QUIRREL_SERVER_URL}/tokens/{NAME_OF_TOKEN}

The fields inside of {} are placeholders and should be replaced by you.

Save the returned token for the next step.

Connect your application to the Quirrel deployment

Configure your application to connect to your Quirrel deployment by specifying the following two environment variables:
