如何向客户分发自动处理Gmail的Google Apps Script？

Hey there! Let's break down your questions one by one based on Google Apps Script (GAS) policies and real-world distribution best practices:

1. Do I have to open-source my script? #

Nope, Google doesn’t force you to open-source your GAS project—even though it’s built on JavaScript. Here’s the breakdown:

• If you’re distributing it commercially (either to individual users or businesses), you can keep it closed-source. Users won’t get direct access to your code unless you intentionally share the GAS project link or export the script files.
• The only time you’d need to open-source is if you’re using open-source dependencies in your script and those licenses require it, or if you explicitly promise open-source access as part of your offering.
• For private use or client-specific deployments, closed-source is totally standard and acceptable.

2. Which deployment option should I choose for user distribution? #

Your use case (automated Gmail bot running on time-driven triggers, commercial use, server-side execution) narrows down the best options. Let’s evaluate each:

• Deploy as web app: Not ideal here. Web apps require an HTTP request to trigger execution, which doesn’t align with your minute-by-minute time-driven workflow.
• Deploy as API executable: Useful if you want other services to call your script via API, but not great for end-users who need a seamless Gmail-integrated experience.
• Register in Chrome Web Store: This pairs perfectly with a web add-on (see below) and lets users discover and install your bot directly from the store. It’s the most user-friendly public distribution method.
• Deploy as web add-on: This is your best bet. Web add-ons integrate directly into the Gmail interface (e.g., sidebar), and you can configure the installation flow to automatically set up the time-driven trigger for users once they authorize the app. It’s designed for Google Workspace apps like Gmail, so it fits your use case like a glove.
• Deploy from manifest: This is the underlying method for web add-ons (you’ll use a manifest.json file to define the add-on’s settings), so it’s not a separate option but part of the web add-on deployment process.

Short answer: Go with Deploy as web add-on and publish it to the Chrome Web Store (or Google Workspace Marketplace for enterprise clients) for the smoothest user experience.

3. Is Chrome Web Store the only distribution route for commercial use? And can Gmail add-ons be paid? #

Distribution alternatives: #

No, you don’t have to use the Chrome Web Store. Here are other commercial-friendly paths:

• Direct project sharing: For small-scale or enterprise clients, you can share a copy of your GAS project with them (via the "Share" button in the script editor). They’ll need to copy it to their own account, authorize permissions, and set up the trigger themselves. You can charge for setup support or customizations.
• Google Workspace Marketplace: Target enterprise clients by publishing your add-on here. It’s integrated with Google Workspace admin consoles, making it easier for businesses to deploy your bot across their team.
• Custom enterprise deployment: Build a tailored version of your bot for a specific business, deploy it directly to their Google Workspace domain, and charge a flat fee or recurring service cost. No public distribution needed.

Paid Gmail add-ons: #

Absolutely not—Gmail add-ons can be paid! Both the Chrome Web Store and Google Workspace Marketplace support paid listings:

• You can set one-time purchase prices or recurring subscriptions.
• Just make sure you follow Google’s monetization policies (e.g., clear pricing disclosures, no hidden fees) and comply with data privacy rules since you’re handling user Gmail data.

A quick note: Regardless of your distribution method, always be transparent with users about how their Gmail data is processed, and ensure you have a clear privacy policy in place—this is mandatory for commercial offerings.
