Custom Domain

A custom domain in Bubble means connecting your own domain name, like yourapp.com, to your Bubble app instead of using the default bubbleapps.io subdomain that every Bubble app gets by default.

Using a custom domain makes your app feel like a real product. It builds trust with users, supports brand consistency, and is required for most professional or commercial launches.

Key Takeaways

• Replaces default URL: A custom domain swaps the bubbleapps.io address for your own domain, like myapp.com or app.mycompany.com.
• Requires a paid plan: Custom domains are only available on Bubble's paid plans. The free tier keeps the default bubbleapps.io subdomain.
• DNS configuration required: You point your domain to Bubble's servers by updating DNS records at your domain registrar before the connection activates.
• SSL included: Bubble automatically provisions an SSL certificate for custom domains so your app loads over HTTPS without any manual setup.

What is Custom Domain in Bubble?

A custom domain in Bubble is a domain name you own and connect to your Bubble app through the app's domain settings. Once set up, your app is accessible at your domain rather than the default bubbleapps.io address Bubble assigns by default.

Every new Bubble app gets a free subdomain like yourapp.bubbleapps.io. A custom domain replaces that with a URL you control and brand as your own.

• Domain ownership: You purchase the domain from a registrar like Namecheap, GoDaddy, or Google Domains, then connect it to Bubble through DNS settings.
• Subdomain option: You can connect either a root domain like yourapp.com or a subdomain like app.yourcompany.com depending on your setup needs.
• SSL automatic: Bubble handles SSL certificate provisioning for your custom domain, so HTTPS works from the moment your DNS propagates.

Custom domains are standard practice for any app going to real users. The default bubbleapps.io URL works for testing but signals to users that the product is not production-ready.

How Custom Domain Works in Bubble

In your Bubble app's Settings, go to the Domain and Email tab and enter your custom domain. Bubble provides a CNAME or A record that you add to your domain's DNS settings at your registrar. Once DNS propagates, your app loads at the new domain.

The setup process takes about ten minutes on the Bubble side. DNS propagation can take anywhere from a few minutes to 48 hours depending on your registrar and TTL settings.

• Bubble settings: Go to Settings, then Domain and Email, and enter your domain name. Bubble shows you the DNS records you need to add.
• Registrar DNS panel: Log into your domain registrar's DNS management panel and add the CNAME or A record that Bubble provides in its settings.
• Propagation wait: After saving the DNS records, wait for propagation. Bubble's domain settings panel shows a status indicator when the connection is confirmed.

Understanding how DNS records work helps you set up the connection correctly the first time. The most common mistake is adding the wrong record type or entering the value with a trailing dot that the registrar does not expect.

Why Custom Domain Matters for No-Code Apps

A custom domain signals professionalism and builds user trust. It makes your Bubble app look and feel like a real product rather than a prototype. For commercial apps, it is a non-negotiable part of a credible launch.

Users notice URLs. A bubbleapps.io address tells a sophisticated user that the product is built on a no-code platform and may not be production-ready. A custom domain removes that concern entirely.

• Brand credibility: A domain you own reinforces your brand identity and makes the app feel like a standalone product, not a builder tool output.
• User trust: HTTPS on a real domain makes users more comfortable logging in, sharing data, and making purchases through your app.
• SEO benefits: If your Bubble app is public-facing with content, a custom domain makes it indexable under your brand's domain rather than Bubble's.

Apps launched without a custom domain often face user hesitation. Fixing it later is easy, but starting with it in place sets the right tone from day one.

Common Issues When Setting Up a Custom Domain in Bubble

The most common issues are DNS record conflicts from previous configurations, missing propagation time before checking the connection, and using a domain that is not yet fully transferred from a previous registrar.

Most custom domain issues are DNS-related and resolve on their own once the correct records are in place and propagation completes.

• Conflicting records: If your domain already has CNAME or A records pointing elsewhere, you need to remove or update them before adding Bubble's records.
• TTL delays: Low TTL settings speed up propagation. High TTL settings at your registrar mean changes take longer to reach all DNS servers globally.
• Domain transfer timing: If you recently transferred the domain to a new registrar, it may be locked for a few days, preventing DNS changes from saving.

Always use a DNS propagation checker tool to confirm your records are live before assuming the connection has failed. Most issues are timing-related, not configuration errors.
