Lean Domain Search vs NamoLux: Fast Availability vs Quality Scoring
Lean Domain Search finds available .com domains fast. NamoLux scores the quality of generated names. Here's how they compare and when to use each.
Lean Domain Search is one of the most efficient tools for finding available .com domains — you type a word, and it instantly shows hundreds of available .com combinations using that word as a prefix, suffix, or embedded term. NamoLux takes a different approach: generate brand-quality names from a creative brief and score each one for brand strength. Here's how they actually compare for startup naming.
What Lean Domain Search Does
Lean Domain Search is a single-purpose tool built by Matt Mazur. You enter a keyword, and it returns all available .com domains containing that keyword. Results are filterable by position (prefix, suffix, or anywhere) and sortable by length or alphabetical. It's fast, free, and accurate. The entire value proposition is speed of availability checking — not name quality evaluation.
What NamoLux Does
NamoLux generates names using AI from a brand brief — keywords, industry, and desired vibe — rather than simply showing keyword combinations. Every generated name is scored with Founder Signal™ covering phonetics, memorability, brand risk, and domain quality. The output is a ranked shortlist of names worth considering, not an exhaustive list of technically available options.
The Output Quality Difference
This is the fundamental distinction. Lean Domain Search shows you everything available. NamoLux shows you what's actually good. For a keyword like 'track', Lean Domain Search returns hundreds of available .com options: trackpro.com, tracklab.com, trackbase.com, and so on — many of which are generic, unmemorable, or trademarked. NamoLux generates and then filters by quality, returning a shorter list of names that meet a brand-strength threshold.
Availability and quality are independent variables. A domain can be available because it's bad — generic, unmemorable, or already associated with a failed brand. Quality scoring is what separates the 2% of available names worth building on from the other 98%.
When Lean Domain Search Wins
When you have a specific keyword you're committed to including in your domain and you want to exhaustively survey what's available. If you're building an affiliate site or content site around a specific keyword, Lean Domain Search is the faster starting point — the exact-match nature of its results is a feature, not a bug.
When NamoLux Wins
When you're naming a startup or brand from scratch and you don't have a specific keyword locked in. When quality evaluation matters more than exhaustive availability surveys. When you want to compare options based on measurable brand-strength criteria rather than choosing between available options based on gut feel.
Combining Both Tools
A practical workflow: use NamoLux to generate quality-scored name candidates that you wouldn't have thought of from a single keyword. For any candidate with a strong Founder Signal™ score that you want to explore further (different prefix/suffix combinations, related words), run that name through Lean Domain Search to see the full landscape of available .com variants. The two tools work well together as sequential steps.
Start with brand quality, then check availability — the order that produces better naming decisions.

Does Lean Domain Search work for TLDs other than .com?
Lean Domain Search is primarily focused on .com domains. It's optimised specifically for finding available .com names that contain your keyword. NamoLux checks availability across .com, .io, .ai, and .co simultaneously, which is more useful for founders open to non-.com TLDs.
Is Lean Domain Search still maintained?
As of 2026, Lean Domain Search operates but has received limited updates in recent years. Its core availability checking function still works reliably. For AI-generated name ideas and quality scoring, NamoLux provides a more modern toolset — but for pure .com availability mapping of keyword combinations, Lean Domain Search remains useful.
Are keyword-combination domains from Lean Domain Search good for branding?
Occasionally, but rarely. Most keyword-combination .com domains (trackpro.com, quickinvoice.com, smartforms.com) are descriptive and generic rather than brandable. The best startup names don't describe the product — they evoke a feeling or create a distinctive brand identity. NamoLux's AI generation and quality scoring are specifically designed to find names that clear a brand-strength bar, not just a keyword-availability bar.
