Domainbar

What is Domainbar?

Domainbar is a lightweight macOS menu bar app for checking domain name availability. Its core purpose is to let you type a domain name and immediately see whether it’s available or taken—without switching away from what you’re doing.

It supports checking multiple top-level domains (TLDs), saves your search history with timestamps, and provides quick actions such as rechecking and opening a result in your default browser.

Key Features

• Instant availability checks from the menu bar: Click the globe icon, enter a domain, and get an available/taken result quickly.
• Auto-complete TLD for single-entry queries: Type a base name like “myapp” to automatically check the corresponding “myapp.com”.
• Explore and check 30+ TLDs: Use “More TLDs” to check options such as .net, .io, .ai, .dev, .app, .co, .xyz, and others with a single click.
• Search history with results and timestamps: Each check is saved so you can revisit earlier domains and their availability.
• Recheck and open actions: Refresh an existing history entry to update the result, and open a domain in your default browser.

How to Use Domainbar

1. Install and launch Domainbar on your Mac.
2. From the menu bar, click the globe icon.
3. Type the domain name you want to check and press Enter to see whether it’s available or taken.
4. If you want other endings beyond the default, choose More TLDs to check additional TLDs.
5. Use the saved history to revisit previous searches, refresh results, or open a domain in your browser.

Use Cases

• Developer choosing a project name: Quickly test whether a candidate domain (including common TLDs) is available while you’re planning a repository or documentation site.
• Designer validating brand availability: Check that a brand-related domain is available before committing to a web presence, using the app without leaving design work.
• Entrepreneur comparing domain options: Use the history list to keep track of different name/TLD combinations and recheck later when decisions evolve.
• Creator checking multiple extensions: Enter a base name once (with auto-complete) and then switch to other TLDs via “More TLDs” to explore alternatives.
• Ongoing domain monitoring: Refresh a prior history entry to see updated availability without running a new search from scratch.

FAQ

• What system requirements does Domainbar have? Domainbar requires macOS 14.0 or later.

• Where do I use Domainbar? It runs as a menu bar app on macOS. You open it by clicking the globe icon in your menu bar.

• Does Domainbar check only .com domains? The app auto-checks .com by default (via auto-complete). You can also check additional TLDs using More TLDs.

• Does Domainbar store my past checks? Yes. It saves your search history, including each result and a timestamp, so you can revisit earlier checks.

• Is any data collected by the app? The app’s App Store privacy information states that the developer does not collect any data from this app (as indicated by the developer on the listing).

Alternatives

• Dedicated domain registrar search pages: Use a registrar’s website to check availability and purchase domains; these are typically full web workflows rather than a quick menu bar check.
• DNS/WHOIS lookup tools for domain queries: These tools can help verify domain status, but the workflow may be more manual and less oriented around quick TLD exploration.
• Browser-based domain availability checkers: Similar job (checking availability), but they require switching to a browser tab instead of working directly from the macOS menu bar.
