Not a directory of other people's tools. A curated collection of 20+ focused micro-sites built by one independent developer, each committed to one niche, all actually free forever.
16 Categories
Every tool lives on its own dedicated site, built for speed and clarity. Pick a category, find your tool.
Our 5 Commitments
These are not marketing slogans. These are constraints we build every single tool under.
Every site ships with modern typography, coherent palettes, and polished micro-interactions. We respect your eyes, not just your clicks.
Tool usable in two clicks. Zero onboarding. Static HTML, everything client-side, page loads under 1.5 seconds on any connection.
No signup, no "create account to export", no paywall, no upsell. The contract is clear from second one: use everything, forever.
60% of users come from phones. We design for 375px screens first, then scale up. Touch targets, input modes, and sticky controls built in.
Three ad slots maximum. Never above the fold. Never between your input and result. Tools work perfectly even with an ad blocker on.
A dedicated suite of sleep tools: bedtime calculator, sleep cycle planner, nap optimizer, and more. Because better rest starts with better timing.
Visit sleepcalcs.comHello. This is a small project built by one independent developer based in France. The Free Collection started in early 2026 with a simple premise: build genuinely useful tools, make them completely free, and ship them on their own dedicated sites so each one can breathe.
Why 20 separate sites instead of one big platform? Because a dedicated sleep calculator site serves you better than a sleep tab buried inside a 500-tool warehouse. Each micro-site gets its own design, its own focus, its own commitment to doing one thing well.
