DeepAgent Apps

Prompt, run, edit, and deploy full-stack websites.

Think of DeepAgent as your go-to coding assistant. It's here to help you bring your ideas to life, even if you're not a seasoned programmer. Like any helpful companion, DeepAgent is powerful - but it works best when you guide it well.

Large Language Models (LLMs) can sometimes be unpredictable. That's why it's important to start small, test often, and build step by step. Begin with a simple version of your app, check that it works, and then gradually add features. This approach keeps things smooth and helps avoid confusion.

In this guide, we'll share a few easy tips to help you get the most out of your DeepAgent experience and make "vibe coding" more fun and productive. It covers:

How to build apps with DeepAgent?

How does DeepAgent help with vibe coding?

DeepAgent helps you get started with vibe coding. Start with something simple and then learn how to nudge the AI to make changes, fix bugs, and iterate.

DeepAgent is meant for full-stack apps but we will start with simple apps and front-end heavy websites.


How does it work?

Here are the steps to using DeepAgent to create apps:

  1. Start with a simple prompt
  2. Check out the pages that the AI built
  3. Ask the AI to make edits
  4. When you are ready, hit deploy to publish the app
  5. We will give you a friendly URL to share with the world. You can also host your apps on custom domains that you own.

What are the key capabilities of DeepAgent


Limitations of DeepAgent

While DeepAgent is powerful and evolving fast, there are a few limitations to keep in mind:

We're actively working on expanding what DeepAgent can do—but for now, it's ideal for rapid prototyping, MVPs, and simpler full-stack apps.


Managing Your Apps

All the apps you create with DeepAgent can be accessed and managed easily through the Apps Management Console.

From there, you can:

Whether you're refining an existing app or managing multiple projects, the console gives you full control in one place.


How to Add a Database to Your App?

If your app requires a database, you don't need to worry about setting one up yourself. Just mention your data needs in your prompt, and DeepAgent will create the necessary database for you, including tables, fields, and sample data when needed.

Once the app is created successfully, you can view/export the database from Apps Management Console or respective DeepAgent conversation.


App deployment & hosting

With DeepAgent, deploying your app is incredibly simple.

Abacus.AI hosted domain

Use this if you want a fast, no-setup way to get your app online.

  1. Click the "Deploy" button in the top-right corner of your App workspace.
  2. Select the "Abacus.AI Domain" tab.
  3. Enter your desired subdomain (e.g., mycoolapp.abacusai.app) in the input box.
  4. Click "Deploy".

Custom Domain

Point your existing domain to the app by updating your nameservers through your domain provider.

Step 1: Register Your Custom Domain

  1. Pick a domain name relevant to your app.
  2. Use a registrar like GoDaddy, Namecheap, or Google Domains to purchase it.
  3. Register the domain, ensuring your contact details are correct. Save your login credentials for later use.

Step 2: Connect and Deploy with DeepAgent

  1. Open the chat where your app is being built or a custom domain in the apps management console.
  2. Click the "Deploy" button.
  3. Select the "Custom Domain" tab.
  4. Add your domain and follow the instructions to verify it by updating the nameservers in your registrar dashboard.
  5. Once verified, click "Deploy" and your app will be live on your domain!

Once deployed, you'll find your live app's link under the "Deployed URL" section.

Vibe Coding Guide

Effective Prompting: Crisp, Concise, and Contextual

Your app is only as good as the instructions you give it. That's why we recommend following:

The more clearly you explain what you want, the more likely you are to get the results you're aiming for.


Build Iteratively with Checkpoints

Don't try to build everything at once—build your app step by step.

Before you start prompting, take a moment to think like a product manager or engineer. Break down your app idea into smaller parts or milestones. Then, build and test one part at a time.

Here's a simple flow to follow:

  1. Break it down – Split complex features into small, manageable tasks.
  2. Prompt the AI – Ask DeepAgent to build just one task at a time.
  3. Test immediately – Use the preview window to check if it works the way you expect.
  4. Decide
    • If it works: great! Move on to the next task.
    • If it doesn't: roll back and try again.

DeepAgent automatically saves your progress as checkpoints, like save-points in a game. You can roll back up to the last 5 checkpoints, so make sure to test after each step. That way, you won't lose a version that was working well.

Building in small steps keeps things stable, makes debugging easier, and helps you stay in control.


Authentication and RBAC Made Easy

DeepAgent takes the pain out of setting up login and access control.

With built-in support for Authentication and Role-Based Access Control (RBAC), you don't need to worry about technical setup or third-party tools. There's no coding, no configuration, and no external integrations required.

Just describe what kind of login system or access control you want in your prompt, and DeepAgent will handle the rest—quickly and securely.


Built-In Database Support

Need a database? DeepAgent sets it up for you—automatically.

If your app requires a database, you don't need to worry about setting one up yourself. Just mention your data needs in your prompt, and DeepAgent will create the necessary database for you, including tables, fields, and sample data when needed.

Sometimes, you might notice the app using dummy data instead of a real database—especially in early versions or quick mockups. If that happens, simply prompt the AI with something like: "Set up a real database and connect it to this app.

DeepAgent will replace the dummy data with a proper backend setup so your app is ready for real users and dynamic content.


Launch your app in one click—no setup, no stress

With DeepAgent, deploying your app is incredibly simple. You can publish it instantly using a free Abacus-hosted domain—perfect for quick demos, testing, or sharing your work.

Want to use your own domain?

Whether you're launching something personal, professional, or experimental, DeepAgent makes deployment effortless.


Debugging Your App

When you're vibe coding, a few errors are totally normal—don't panic!

If something breaks or doesn't work as expected, DeepAgent can help you fix it. Here's what to do when things go off track:

How to Debug with DeepAgent:

Remember: errors are part of the process. The key is to fix, test, and keep iterating with confidence.
