A curated collection of 20+ focused micro-sites, each committed to one niche. Built by one independent developer, all genuinely free forever.
Every tool lives on its own dedicated site, purpose-built for its niche. Pick a category to explore.
Not a marketing list. These are constraints we build every tool around.
Clean interfaces, careful typography, coherent palettes, and micro-interactions that serve usage. Our sites respect your eyes, not just your clicks.
Tool usable in 2 clicks. Zero onboarding tunnel. Static HTML loaded in under 1.5 seconds. Everything runs client-side, nothing waits on a server.
Zero signup, zero paywall, zero upsell. The contract is clear from second one: use the tool, close the tab. That is the entire experience.
60% of traffic comes from phones. Every tool is designed at 375px before desktop. Touch targets, adapted keyboards, sticky controls: mobile is the reference.
Maximum 3 small ad slots per page. Never above the fold. Never between input and output. Never a popup. You can use every tool with an ad blocker active.
Find your optimal bedtime based on 90-minute sleep cycles, estimate sleep debt, discover your chronotype, and plan naps that actually refresh you. All free, all instant, all private.
Visit SleepCalcs →Hello. This is a small project built by one independent developer based in France. The idea is simple: instead of building one giant platform that tries to do everything, build 20+ focused micro-sites, each dedicated to one niche, each doing that one thing well.
Every site shares the same commitments: no signup, no freemium tier, no email harvest. The tools are funded by respectful advertising, not by selling user data or attention. The pace is sustainable: 2 to 4 new sites per month, each going through a full design and quality cycle.
More about the project →The collection currently includes over 20 micro-sites covering calculators, timers, daily games, file tools, wellness tools, typography utilities, audio recording, and more. Each site is dedicated to one niche and contains multiple individual tools within that focus area. New sites launch every 2 to 4 weeks.
One independent developer based in France. Every site goes through a full design and development cycle: strategic brief, visual design, build, quality audit, and launch. There is no team, no VC funding, no growth pressure. Just one person shipping useful tools at a sustainable pace.
Directories like Mr. Free Tools list third-party tools they do not control. The Free Collection is a curated portfolio of tools we build and maintain ourselves. Every site shares the same commitments: no signup, no freemium, no email harvest, mobile-first design, and respectful advertising.
