Domain Details Review - The Privacy-First Domain Research Tool Built for Indie Makers

Welcome to this Domain Details review 😊!

If you've ever needed to look up domain information, you've probably encountered WHOIS, the decades-old protocol that feels like it's from the 1980s (because it literally is). While it works, it's clunky, inconsistent, and doesn't exactly scream "modern" 😅.

Enter Domain Details, a privacy-first domain research tool that's reimagining how we access domain information. Instead of relying solely on outdated WHOIS, it prioritizes RDAP (Registration Data Access Protocol), the modern successor that provides standardized, structured data, all while keeping your searches private and local-first.

In this review, we'll explore how Domain Details stands out in the domain lookup space, test its core features, and see if it's the tool domain investors, developers, and marketers have been waiting for!

Getting Started & First Impressions

The first thing that strikes you about Domain Details is its philosophy: privacy-first, local-first, and completely free for core features. I like that 👀. The homepage is clean and immediately communicates the value proposition.

The onboarding is frictionless. You can start looking up domains immediately without creating an account. Just type a domain name and hit enter, that's it 😁. No sign-up walls, no credit card required, no tracking.

The interface itself is modern and minimal, with a focus on usability. The design is clean without being sterile, and the navigation is intuitive. You can tell this was built by someone who actually uses domain tools themselves.

Core Features & Functionality

1. RDAP-First Domain Lookup

The heart of Domain Details is its domain lookup feature, and it's genuinely impressive. Here's what makes it special:

RDAP vs. WHOIS: Domain Details prioritizes RDAP (Registration Data Access Protocol) over traditional WHOIS. RDAP is the modern standard that provides:

• Standardized JSON responses (vs. inconsistent WHOIS text)
• Better support for international domain names
• Improved security and privacy controls
• Consistent rate limiting

If a domain's registry hasn't implemented RDAP yet, Domain Details automatically falls back to WHOIS. This hybrid approach means you get the best of both worlds.

Smart URL Handling: One of the cleverest features is the ability to add domaindetails.com/ in front of any URL. Whether you put it before the https:// or replace the www, it'll fetch the domain information. This is incredibly convenient for quick lookups.

Aftermarket Pricing: If a domain is taken, Domain Details shows you live pricing from major marketplaces (Sedo, Dynadot, DomainMarket, Namecheap) with direct links to purchase listings. This transforms it from a lookup tool into a complete research platform for domain investors.

2. Complete Free Tools Suite

Beyond basic lookups, Domain Details offers several powerful free tools:

Bulk Lookup: Look up to 100 domains at once with instant results. Perfect for portfolio management or competitive research. You can export results to CSV, making it easy to work with large datasets.

DNS Lookup: Query DNS records using encrypted DNS-over-HTTPS (Cloudflare 1.1.1.1 with Google DNS fallback). The key here is that your queries never touch Domain Details' servers—everything happens locally in your browser. This is privacy done right.

Pricing Check: Compare domain registration and renewal prices across registrars instantly. Get accurate pricing for registration, renewal, and transfer costs, with multi-year breakdowns to help you find the best deals.

TLD Database: A comprehensive database of all available TLDs with detailed information about each one.

3. Chrome Extension

The Chrome extension is where Domain Details really shines for everyday use. Install it, and you can:

• One-click lookup: Click any domain on any webpage to instantly see its WHOIS data
• Smart detection: Automatically detects domains on webpages and makes them clickable
• Lightning fast: Results appear in a popup without leaving your current tab
• History tracking: Keep track of all domains you've looked up with local storage
• Export options: Export domain data as JSON or copy to clipboard

The extension works on Brave, Edge, and other Chromium browsers too. For domain investors browsing marketplaces or developers debugging DNS issues, this is a game-changer.

4. Free MCP Server for AI Agents

This is genuinely innovative. Domain Details offers a completely free Model Context Protocol (MCP) server that works with Claude, ChatGPT, and any MCP-compatible AI client.

No API keys. No rate limits. No hidden costs. Just connect and start querying.

This opens up possibilities for:

• AI agents that can automatically check domain availability
• Portfolio analysis bots
• Automated monitoring agents
• Competitive analysis tools

The fact that this is free and has no rate limits is remarkable. It's a clear signal that the creator is thinking about the developer and AI community, not just extracting maximum revenue.

5. Domain Monitoring & Pro Features

While the core features are free, Domain Details offers a Pro subscription for power users:

• Domain Monitoring: Monitor up to 25 domains with real-time notifications for any changes
• Historical Data: Access complete historical data since tracking began, with 1 year of lookup history synced across devices
• Priority Support: Direct access to the support team

The Pro pricing is reasonable and the features are genuinely useful for anyone seriously managing domain portfolios.

6. Domain Stories

A unique feature is the "Domain Stories" section—real stories behind major domain acquisitions. You can read about how Loom.com negotiated a $150K deal, how Paddle.com was acquired, and other fascinating domain acquisition stories. It's educational and entertaining, adding real value beyond just lookup functionality.

Privacy & Local-First Architecture

This deserves its own section because it's a core differentiator.

Domain Details is genuinely privacy-first:

• No tracking: Your searches aren't logged or profiled
• No cookies for free users: Browse anonymously without creating an account
• Local-first architecture: Your search history lives on your device using IndexedDB, never sent to servers
• DNS-over-HTTPS: DNS lookups happen directly in your browser, not through Domain Details' servers

This isn't marketing fluff—it's a real architectural choice that prioritizes your privacy over data collection. In a world where most tools are trying to monetize your data, this is refreshing.

Design & User Experience

The design is clean and functional. It's not flashy, but it doesn't need to be. Every element serves a purpose, and the interface guides you naturally through the experience.

The color scheme is modern and accessible. The typography is clear and readable. The layout is scannable. There are no unnecessary animations or distracting elements.

Who Should Use Domain Details?

Domain Details is ideal for:

• Domain Investors: Quick research on domains, expiration dates, ownership verification, and aftermarket pricing
• Developers: Debug DNS issues, verify domain configurations, and check nameserver settings without leaving your browser
• Digital Marketers: Analyze competitor domains, identify opportunities, and research domain patterns
• AI/Agent Developers: Build intelligent agents that can access domain information in real-time
• Anyone who values privacy: If you care about your data and don't want to be tracked, this is your tool
