Domain Tools
Heroku Domains - Product Overview
Introduction to Heroku Domains
Heroku, a cloud Platform as a Service (PaaS), offers a comprehensive solution for managing and configuring custom domains for your applications. Here’s a brief overview of Heroku Domains, their primary function, target audience, and key features.Primary Function
The primary function of Heroku Domains is to allow users to add custom domain names to their Heroku applications. This enables users to make their apps accessible via non-Heroku domains, such as `www.yourcustomdomain.com`, instead of the default Heroku domain (`your_app_name.herokuapp.com`).Target Audience
Heroku Domains are targeted at developers and organizations that use the Heroku platform to deploy, manage, and scale their applications. This includes a wide range of users, from individual developers to digital and software development agencies, and enterprise companies.Key Features
Custom Domain Addition
Users can add custom domains to their Heroku apps without incurring extra charges. This involves confirming ownership of the custom domain, adding it to the app using the `heroku domains:add` command, and configuring the DNS settings.DNS Configuration
Heroku provides specific DNS targets that users need to configure with their DNS providers. For most cases, users need to set up CNAME or ALIAS/ANAME records to point their custom domains to the Heroku-supplied DNS targets. This is crucial because Heroku uses dynamic IP addresses, making A records unsuitable.SSL and Certificate Management
For apps using Heroku SSL (SNI) or Automated Certificate Management, the DNS targets will be in the format of `Domain Ownership Verification
Heroku enforces rules to ensure that domains are not claimed by multiple users or apps. For example, a given domain can only be added to a single Heroku app, and wildcard domains require ownership of all existing subdomains.DNS Propagation and Testing
DNS changes can take time to propagate, and users can test their DNS setup using online tools or command-line tools like `dig` and `host`. By using Heroku Domains, developers can enhance the accessibility and professionalism of their applications, making it easier for users to find and interact with their apps. Heroku Domains - User Interface and Experience
Heroku Dashboard
The primary interface for managing Heroku domains is the Heroku Dashboard. This web interface allows users to perform various tasks related to their apps, including domain management. Here, you can easily view and manage your app’s domains and subdomains. The dashboard is organized into clear sections, such as the app list, application overview, and settings, which helps in locating the necessary tools quickly.
Domain Management
To manage domains, you can go to the “Settings” tab within your app’s overview page on the Heroku Dashboard. Here, you will find the “Domains” section where you can add, configure, and verify custom domains and subdomains. This process involves adding a CNAME record with your DNS provider to point to Heroku’s DNS target, and then verifying the domain within the Heroku Dashboard.
Heroku CLI
For those who prefer command-line interactions, Heroku provides a CLI that allows you to manage domains and subdomains efficiently. You can use commands like heroku domains:add example-domain.com or heroku domains:add about.example-domain.com to add domains and subdomains, respectively. This method is particularly useful for automating domain management tasks.
PointDNS Add-on
Heroku also offers the PointDNS add-on, which provides a friendly and easy-to-use interface for managing all your domains. With PointDNS, you can add and customize DNS records, set up permanent HTTP redirects, and manage other DNS-related tasks. This add-on integrates seamlessly with the Heroku Dashboard and CLI, making domain management more comprehensive and convenient.
Ease of Use
The interface is designed to be intuitive, allowing users to manage their domains without needing extensive technical knowledge. The steps for adding and verifying domains are well-documented and straightforward, reducing the learning curve for new users. Additionally, the Heroku Dashboard and CLI provide clear feedback and error messages, helping users troubleshoot any issues that may arise.

Heroku Domains - Key Features and Functionality
Heroku Domains Overview
When discussing Heroku Domains, the primary features and functionality revolve around managing and configuring custom domains for Heroku applications, rather than integrating AI specifically into the domain management tools. Here are the key features and how they work:Custom Domain Names
Heroku allows you to add custom domain names to your applications. This involves purchasing or using a custom domain name and then configuring it with your Heroku app. You need to add the custom domain to your application, set up the necessary DNS records (typically CNAME or ALIAS/ANAME records), verify your domain, and enable an SSL certificate.DNS Configuration
To point your custom domain to your Heroku app, you must set up a CNAME record or an equivalent (like ALIAS or ANAME records) with your DNS provider. This record should point to the DNS target provided by Heroku. This setup is crucial because Heroku uses dynamic IP addresses, which are not compatible with static IP-based A records.Subdomains
Heroku supports the creation of custom subdomains for your applications. You can set up a wildcard DNS record to route all subdomains of a given domain to your Heroku app. This is useful for creating unique URLs for different parts of your application or for different users. Within your app, you can use middleware to handle requests based on the subdomain.Management via Heroku CLI and Dashboard
You can manage your domains using the Heroku CLI or the Heroku Dashboard. Commands like `heroku domains` help you view and manage the domains associated with your app. This makes it easy to add, remove, or update your custom domains without needing to reconfigure DNS settings manually.Scalability
Heroku domains are designed to be scalable, meaning they can handle large amounts of traffic and requests without affecting the performance of your application. This scalability ensures that your app remains accessible and responsive even under high load conditions.Security
For security purposes, Heroku requires you to verify your account to add custom domains. Additionally, enabling SSL certificates is necessary to ensure secure communication between your users and your application.AI Integration
Currently, there is no specific integration of AI into the domain management tools on Heroku. The AI-related features on Heroku, such as Managed Inference and Agents, are part of a separate offering aimed at integrating AI models into applications, but these do not directly relate to the management of custom domains.Conclusion
In summary, Heroku Domains focus on providing a straightforward way to manage custom domain names and subdomains for Heroku applications, ensuring scalability, security, and ease of management, but they do not include AI-driven features within the domain management itself. Heroku Domains - Performance and Accuracy
Performance
Heroku Domains are optimized for scalability and resiliency, especially when using the right DNS configurations. Here are some performance highlights:
- Avoiding A-Records: Heroku strongly advises against using DNS A-records for root domains due to their limitations in dynamic IP environments. A-records require a static IP address, which can lead to availability issues when the IP address changes.
- Using CNAME-like Records: Instead, Heroku recommends using CNAME-like records (such as ALIAS or ANAME records) for root domains. These records allow Heroku to manage the set of IPs associated with your domain, ensuring better uptime and flexibility.
Accuracy
The accuracy of Heroku Domains is ensured through several mechanisms:
- Domain Ownership Rules: Heroku enforces strict rules to prevent multiple users or apps from claiming the same domain. For example, a given domain can only be added to a single Heroku app, and wildcard domains can only be added if you own all existing apps using corresponding subdomains.
- Automated Certificate Management (ACM): Heroku’s ACM automates the management of SSL certificates, ensuring that your domains are securely configured without manual intervention. However, there are limitations, such as not supporting IPv6 AAAA DNS records or internal routing.
Limitations
While Heroku Domains offer strong performance and accuracy, there are some limitations to be aware of:
- Custom Domain Length: Custom domains cannot be longer than 64 characters.
- Wildcard Domains in Private Spaces: Private Space apps using ACM cannot have wildcard domains.
- SSL and Subdomain Redirection: Using subdomain redirection can cause browser errors when accessing the root domain over SSL (e.g., `https://example.com`). Therefore, ALIAS/ANAME configurations are recommended for root domains.
Areas for Improvement
- Support for IPv6: Heroku’s ACM does not currently support IPv6 AAAA DNS records, which might be a limitation for some users.
- Internal Routing Compatibility: ACM is not compatible with internal routing, which could be an issue for certain application architectures.
In summary, Heroku Domains are well-optimized for performance and accuracy, especially when the recommended DNS configurations are followed. However, users should be aware of the specific limitations and ensure they align with their application’s requirements.

Heroku Domains - Integration and Compatibility
Integrating Heroku Domains
Integrating Heroku domains with other tools and ensuring compatibility across various platforms involves several key steps and considerations.Adding Custom Domains
To integrate a custom domain with your Heroku app, you need to follow a series of steps. First, you must own or purchase the custom domain name through a domain registration service. Then, you add the custom domain to your Heroku app using the `heroku domains:add` command via the Heroku CLI. For example, to add `www.example.com` to your app, you would use: “`bash $ heroku domains:add www.example.com -a example-app “` Heroku will provide a DNS target, such as `whispering-willow-5678.herokudns.com`, which you need to configure with your DNS provider using a CNAME record.DNS Configuration
Heroku does not provide DNS hosting services, so you must configure your DNS records with your domain provider. For subdomains and custom domains, you typically use CNAME records. For root domains, you need to use ALIAS or ANAME records because Heroku uses dynamic IP addresses, which are not compatible with A records.Compatibility with DNS Providers
Heroku domains can be integrated with various DNS providers. For instance, if you are using Google Domains, you would create a CNAME record with the name of your subdomain and the value provided by Heroku (e.g., `some-letters.herokudns.com`). You may also need to set up domain forwarding for root domains.Multiple Subdomains and Wildcard Domains
Heroku allows you to add multiple subdomains to a single app. You can also use wildcard domains (e.g., `*.example.com`) to direct all subdomains of a given domain to your Heroku app. This is particularly useful for applications that need to handle various subdomains dynamically.Platform and Device Compatibility
Heroku domains are designed to be scalable and can handle large amounts of traffic, making them compatible with a wide range of platforms and devices. Since Heroku is a cloud platform, it supports a variety of applications and can be accessed from any device with an internet connection. The use of custom domains and subdomains enhances the branding and accessibility of your application across different devices and platforms.Security and Verification
To ensure security, Heroku enforces rules such as verifying your Heroku account before adding domains and ensuring that a given domain can only be added to a single Heroku app. Additionally, Heroku uses DNSSEC to authenticate requests to its domains, providing an extra layer of security.Conclusion
In summary, integrating Heroku domains with other tools involves careful DNS configuration, compatibility with various DNS providers, and adherence to Heroku’s domain management rules. This ensures that your application is securely and reliably accessible via custom domains and subdomains across different platforms and devices. Heroku Domains - Customer Support and Resources
