⚠️ Open SaaS is now running on Wasp v0.13! If you're running an older version of Open SaaS, please follow the migration instructions here ⚠️


This guide will show you how to integrate analytics for your app. You can choose between Google Analytics and Plausible.

Google Analytics is free, but uses cookies, so you’ll probably want/need to implement the Cookie Consent Modal when using it.

Plausible is an open-source, privacy-friendly alternative to Google Analytics. You DO NOT have to use the cookie consent modal with Plausible, as it does not use cookies. It’s also easier to use than Google if you use their hosted service, but be aware it is a paid feature. It is completely free if you want to self-host it, although this comes with some additional setup steps.

If you’re looking to add analytics to your blog, you can follow the Adding Analytics to your Blog section at the end of this guide.


Hosted Plausible

Sign up for a hosted Plausible account here.

Once you’ve signed up, you’ll be taken to your dashboard. Create your site by adding your domain. Your domain is also your PLAUSIBLE_SITE_ID in your .env.server file. Make sure to add it.

Terminal window
PLAUSIBLE_SITE_ID=<your domain without www>

After adding your domain, you’ll be taken to a page with your Plausible script tag. Copy and paste this script tag into the main.wasp file’s head section.

app OpenSaaS {
wasp: {
version: "^0.13.0"
title: "My SaaS App",
head: [
"<your plausible script tag here>",

Go back to your Plausible dashboard, click on your username in the top right, and click on the Settings tab. Scroll down, find your API key and paste it into your .env.server file under the PLAUSIBLE_API_KEY variable.

Self-hosted Plausible

Plausible, being an open-source project, allows you to self-host your analytics. This is a great option if you want to keep your data private and not pay for the hosted service.

Google Analytics

After you sign up for Google analytics, go to your Admin panel in the bottom of the left sidebar and then create a “Property” for your app.

Once you’ve completed the steps to create a new Property, some Installation Instructions will pop up. Select install manually where you should see a string that looks like this:

Terminal window<your-google-analytics-id>

and copy and paste the Google Analytics ID into your .env.client file to get it working with the Cookie Consent Modal provided with this template:

REACT_APP_GOOGLE_ANALYTICS_ID=<your-google-analytics-id> # e.g. G-1234567890

Then, set up the Google Analytics API access by following these steps:

  1. Set up a Google Cloud project: If you haven’t already, start by setting up a project in the Google Cloud Console.

  2. Enable the Google Analytics API for your project: Navigate to the “Library” in the Google Cloud Console and search for the “Google Analytics Data API” (for Google Analytics 4 properties) and enable it.

  3. Create credentials: Now go to the “Credentials” tab within your Google Cloud project, click on + credentials, and create a new service account key. First, give it a name. Then, under “Grant this service account access to project”, choose viewer.

  4. Create Credentials: When you go back to Credentials page, you should see a new service account listed under “Service Accounts”. It will be a long email address to ends with Click on the service account name to go to the service account details page.

    • Under “Keys” in the service account details page, click “Add Key” and choose Create new key.

    • Select “JSON”, then click “Create” to download your new service account’s JSON key file. Keep this file secure and don’t add it to your git repo – it grants access to your Google Analytics data.

  5. Update your Google Anayltics Settings: Go back to your Google Analytics dashboard, and click on the Admin section in the left sidebar. Under Property Settings > Property > Property Access Management Add the service account email address (the one that ends with and give it Viewer permissions.

  6. Encode and add the Credentials: Add the client_email and the private_key from your JSON Key file into your .env.server file. But be careful! Because Google uses a special PEM private key, you need to first convert the key to base64, otherwise you will run into errors parsing the key. To do this, in a terminal window, run the command below and paste the output into your .env.server file under the GOOGLE_ANALYTICS_PRIVATE_KEY variable:

    Terminal window
    echo -n "PRIVATE_KEY" | base64
  7. Add your Google Analytics Property ID: You will find the Property ID in your Google Analytics dashboard in the Admin > Property > Property Settings > Property Details section of your Google Analytics property (not your Google Cloud console). Add this 9-digit number to your .env.server file under the GOOGLE_ANALYTICS_PROPERTY_ID variable.

Adding Analytics to your Blog

To add your analytics script to your Astro Starlight blog, all you need to do is modify the head property in your blog/astro.config.mjs file.

Below is an example of how to add Google Analytics to your blog:

export default defineConfig({
site: '',
integrations: [
// ...
head: [
tag: 'script',
attrs: {
tag: 'script',
content: `
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', '<YOUR-GOOGLE-ANALYTICS-ID>');
