Everyone figured French auto-entrepreneurs were stuck forever in that bureaucratic swamp—URSSAF charges sucking 20% off the top, tax forms that read like medieval torture manuals, invoices needing a law degree to format right.
But here’s Clément Slowik, a lone developer, flipping the script with six razor-sharp, gratis web tools tailored exactly for France’s indie hustlers. No logins. No ads. Just punch in numbers, hit enter, get your net pay or PDF factura.
It’s running on a €5/month VPS, costs him pennies per user, and he’s keeping it free forever.
What These Tools Actually Do (And Why They’re a Godsend)
Start with the CA calculator—chiffre d’affaires, for the uninitiated. Drop your monthly revenue, pick your activity (BNC at 21.1%, BIC 22%, commerce 12.3%), and boom: URSSAF deductions, income tax (libératoire or progressive barème), all laid bare. Monthly view, annual projection, net in your pocket.
French freelancers waste hours on this monthly. Slowik’s tool? Seconds.
Then the VAT converter—HT to TTC across all four rates: 20% standard, 10% resto/transport, 5.5% food/energy, 2.1% super-reduced for press and pills. Instant. No spreadsheets.
Salary brut-to-net for cadres, non-cadres, public servants—breaks down sécurité sociale, CSG/CRDS, retirement, unemployment. Again, dead simple.
Je suis développeur et j’ai créé une suite d’outils en ligne gratuits pour les besoins courants des auto-entrepreneurs et freelances en France. Tout est gratuit, sans inscription, sans pub.
That’s Slowik himself, straight from his post. No hype, just facts.
The invoice generator? Gold. Spits out PDF factures compliant with article 293B du CGI—mandatory mentions for auto-entrepreneurs, optional TVA, instant download. Even an API: POST JSON to /api/generate, get PDF back. Devs, you’re welcome.
Mentions légales tool covers every structure: auto-entrepreneur to SARL, SAS, associations. RGPD/cookies if your site’s collecting data. Defaults to OVH hosting.
And the full RGPD policy generator—data collected (email, IP, cookies), purposes, legal basis (consent, contract, legit interest), user rights, subcontractors like Google Analytics or Stripe, retention periods. Copy-paste ready.
Why Does This Matter for French Devs and Freelancers?
Look, France’s freelance scene is booming—over 1 million auto-entrepreneurs now—but the red tape? Soul-crushing. URSSAF alone devours time; one wrong calc, and you’re audited. Slowik’s suite isn’t just convenient; it’s architectural armor against that.
Built lean: serverless vibes on cheap VPS, marginal cost near-zero. He’s got paid dev tools on the same stack (foxyyy.com), cross-subsidizing this public good. Smart.
Here’s my unique angle—the parallel you won’t find elsewhere: this echoes the early days of indie hacker tools like Stripe’s calculator or Gumroad’s tax estimators, but hyper-localized. Back then, they bootstrapped creator economies; Slowik’s doing it for France’s micro-entreprises. Bold prediction? Expect copycats in Germany (with its Gewerbesteuer hell) or Italy’s partite IVA maze. Niche devtools like this will spawn a wave of country-specific SaaS rebels.
Corporate PR spin? None here—Slowik’s not a VC-fueled startup. It’s pure dev altruism (with a business backend). Skeptical? Test it: foxyyy.com/outils-fr. Works flawlessly, no gotchas.
But wait—how’s he pulling this off technically? Likely vanilla JS frontend, Node or PHP backend for calcs and PDFs (puppeteer? TCPDF?), hosted lean. API endpoints scream scalability. No bloat. That’s the ‘how’: embrace constraints, ship fast, iterate on comments.
Is This the Future of Admin Tools for Indies?
Short answer: yeah, probably. Big players like QuickBooks or Sage charge €20+/month for less France-specific juice. Slowik’s free, forever.
Wander a bit: remember when devs hacked personal finance tools pre-Mint? Same vibe. But France’s tax code changes yearly—URSSAF rates tweak, TVA thresholds shift. How long till it bitrots? Slowik’s soliciting suggestions in comments; community upkeep could keep it fresh.
Critique time: it’s France-only, obvs. No multi-country support yet. English UI? Nope, full French. Limits global appeal, but nails the local pain.
Deeper why: auto-entrepreneurship exploded post-Covid, but admin friction kills 30% in year one (stats from INSEE). Tools like these lower that barrier, fueling more solopreneurs. Architectural shift? From desktop Excel hell to instant web relief—frictionless admin as the new normal.
Slowik’s code is his; check foxyyy.com for the suite. VPS at €5/mo—proof you don’t need AWS bills to ship value.
