In Mocha, there are two limits that you should be aware of:
  1. Message limits
  2. App size limits

​
Credit Limits

​
How many credits do I get?

Everyone starts with 120 free credits on the Free tier. On a Bronze, Silver or Gold plan you receive 1,500, 4,500, and 25,000 credits per month respectively. These refill every billing cycle.
  • 🥉Bronze: 1,500 credits per month
  • 🥈Silver: 4,500 credits per month
  • 🥇Gold: 25,000 credits per month

​
How do you count credits?

We only deduct credits when an AI operation (code generation or edit) succeeds. You can track your credit balance by clicking the main dropdown menu in the top left corner.

​
Do messages roll over from month to month?

Subscription messages get reset, but purchased and gifted credits are kept forever.

​
I used all my messages by clicking “Fix with AI”, what should I do?

You can email us at [email protected] from the email associated with the account. In general, only use Fix with AI once or twice, if the AI can’t fix it automatically you should try a different strategy or ask for help in our Discord.

​
How can I purchase more messages?

You should subscribe to a higher plan. If you want to buy one-off credits, let us know at [email protected], we are debating adding this as an option if there is demand.

​
App Size Limits

Mocha’s AI agent can handle apps of virtually any size, with limits varying by subscription tier:
  • 🥉Bronze: Limited app size (suitable for small to medium projects)
  • 🥈Silver: Nearly unlimited app size
  • 🥇Gold: Even larger app size, and uses our greedy agent mode.
Starting with the Silver tier, you can build large, complex applications without worrying about size constraints. The limits are set so high that they’re effectively unlimited for most use cases.

​
I keep seeing “Project size exceeds maximum allowed bronze tier limits”. What can I do?

If you’re on the Bronze tier and encountering size limits, upgrading to Silver or Gold will give you nearly unlimited capacity to continue building your app. The Bronze tier is designed for smaller projects and learning. For production applications or larger codebases, we recommend upgrading to Silver or Gold for the best experience.

Credits FAQ

Credits are consumed when you ask Mocha’s AI to make changes to your app. This includes generating new features, editing existing code, fixing bugs, and any other AI-powered modifications. Credits are also used for Discuss Mode.Credits are not used for:
  • Browsing your project
  • Using Direct Edit Mode to change text
  • Viewing or managing your database
  • Publishing your app
  • Restoring a version
It depends on the complexity of your request. Here are some rough examples:
  • Simple text or styling change: 5-15 credits
  • Adding a new component or section: 15-40 credits
  • Building a new page: 30-60 credits
  • Adding a complex feature with database: 50-100+ credits
  • Using Discuss Mode: 3 credits per request
Smaller, focused requests typically use fewer credits than large, complex ones. We recommend breaking big features into smaller steps.
Subscription credits reset each billing cycle and do not roll over.Purchased credits (one-time purchases) and gifted credits are kept forever and don’t expire.
When you run out of credits, you won’t be able to make AI-powered changes until your credits refresh or you get more. However, you can still:
  • View and browse your project
  • Use Direct Edit Mode for simple text changes
  • Publish your app
  • Access your database
  • Download your code
If you’re stuck mid-project, consider upgrading to a higher tier, or contact [email protected] to discuss options.
We’re exploring adding one-time credit packs based on user demand. If this interests you, let us know at [email protected].Currently, the best way to get more credits is to subscribe to a paid plan (Bronze, Silver, or Gold).
Your credits reset on the anniversary of when you started your subscription. For example, if you subscribed on the 15th of the month, your credits will refresh on the 15th of each following month.You can check your current credit balance and billing date from the main menu in the top left corner of the app.

Scalability FAQ

Mocha apps are hosted on Cloudflare’s global infrastructure, which is designed to handle significant traffic. Your app can serve many concurrent users without you needing to worry about server management or scaling.For most use cases—including small businesses, communities, and growing startups—Mocha’s infrastructure handles the load automatically.
Yes! Mocha’s infrastructure scales automatically. Many users build and run SaaS products, membership sites, and tools with substantial user bases on Mocha.For the best experience with larger applications, we recommend Silver or Gold tiers which have generous limits on app size and published apps.
Mocha apps run on Cloudflare, which automatically handles traffic spikes. You don’t need to configure anything—the infrastructure scales up to meet demand and scales down when traffic subsides.
Storage limits vary by tier. Silver and Gold tiers have very generous limits that accommodate most use cases. If you’re building something that requires large amounts of data storage, consider reaching out to [email protected] to discuss your needs.
