Lean Domain Search vs NamoLux: Fast Availability vs Quality Scoring
Lean Domain Search finds available .com domains fast. NamoLux is a name decision workspace for solo founders. 3 Bulk Check runs and 1 Founder Signal run per UTC calendar month. Pro is £7.99/month. 120 Bulk Check runs and 120 Founder Signal runs per UTC calendar month. Pro also includes saved projects, CSV exports, shareable decision reports, and an ad-free workspace.
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.

Pro is £7.99/month. 120 Bulk Check runs and 120 Founder Signal runs per UTC calendar month. Pro also includes saved projects, CSV exports, shareable decision reports, and an ad-free workspace.
The Output Quality Difference
This is the fundamental distinction. Lean Domain Search expands one keyword into available combinations. NamoLux explores several naming styles from a richer brief, keeps every usable creative candidate visible, and lets the founder apply a separate quality analysis later. Founder Signal never silently filters the generated list.
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.

Check your shortlistFrequently Asked Questions
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. NamoLux is a name decision workspace for solo founders. 3 Bulk Check runs and 1 Founder Signal run per UTC calendar month. Pro is £7.99/month. 120 Bulk Check runs and 120 Founder Signal runs per UTC calendar month. Pro also includes saved projects, CSV exports, shareable decision reports, and an ad-free workspace.
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.
