DEV Community: Zakaria Zoubai

J'ai créé un outil gratuit pour collecter des avis clients vérifiés (et l'intégrer en 2 min sur n'importe quel site)

Zakaria Zoubai — Sun, 30 Aug 2026 10:48:59 +0000

Chaque mission freelance se termine pareil : le client est content, promet de laisser un avis... et on n'entend plus jamais parler de lui.

J'en avais assez de perdre ma preuve sociale à cause de bonnes intentions. J'ai donc créé TestiWall — un outil gratuit pour collecter des témoignages clients vérifiés et les afficher sur ton site.

Le problème que ça résout

Quand un client dit "je vais te laisser un avis", la friction est côté client :

Il ne sait pas sur quelle plateforme aller (Google ? LinkedIn ? Trustpilot ?)
Il ne veut pas créer un compte
Le moment passe, la motivation disparaît

TestiWall donne un lien unique. Le client remplit un formulaire, vérifie son email (sans créer de compte), et le témoignage est en ligne sur ton widget.

Comment ça marche

Inscription gratuite sur testiwall-kappa.vercel.app
Crée un "mur" pour ta prestation ou ton projet
Partage le lien de collecte à tes clients
Ils soumettent → vérifient leur email → le témoignage s'affiche
Tu intègres le widget avec un seul snippet

<div id="testiwall-widget" data-wall-id="TON_ID"></div>
<script src="https://testiwall-kappa.vercel.app/widget.js" async></script>

Ce qui le différencie

Vérification email — aucun faux avis possible
Zéro friction pour le client — pas de compte, 60 secondes max
Embed partout — Webflow, WordPress, Next.js, HTML brut
Gratuit pour toujours — jusqu'à 15 témoignages par mur, murs illimités

Le plan Pro (4,99 €/mois) supprime le badge TestiWall et lève la limite de 15.

Pourquoi c'est utile pour les devs français

Si tu fais du freelance dev, de l'agence web, ou si tu as un SaaS — tes clients satisfaits sont ta meilleure acquisition. Un mur de témoignages vérifiés sur ta page d'accueil convertit mieux qu'une longue description.

Tu peux aussi proposer TestiWall à tes clients web comme valeur ajoutée — c'est gratuit pour eux, et ça se branche en 5 minutes.

Retour d'expérience bienvenu

Je suis notamment curieux de savoir :

Est-ce que la limite à 15 témoignages (plan gratuit) vous semble correcte ?
Quelles intégrations seraient utiles ? (Slack, webhooks, Zapier ?)

I built a free testimonial widget in a weekend — here's how to embed verified reviews on any site

Zakaria Zoubai — Sun, 30 Aug 2026 10:36:56 +0000

Every freelance project ends the same way: client is happy, says "I'll leave you a review!" — and then... nothing.

I got tired of losing social proof to good intentions. So I built TestiWall — a free tool to collect verified testimonials and embed them anywhere in 2 minutes.

The problem I was solving

When a client says they'll leave a review, the friction is too high:

They forget which platform to use (Google? LinkedIn? Trustpilot?)
They don't want to create an account
The moment passes, the motivation dies

TestiWall gives them a single link. They fill a short form, verify their email, done. You get an embeddable widget.

How it works

Sign up free at testiwall-kappa.vercel.app
Create a "wall" for your project/service
Share the collection link with your clients
They submit a testimonial → get an email verification link → testimonial goes live
Embed the widget with one <script> tag

<!-- Paste this where you want testimonials to appear -->
<div id="testiwall-widget" data-wall-id="YOUR_WALL_ID"></div>
<script src="https://testiwall-kappa.vercel.app/widget.js" async></script>

What makes it different

Email verification — no fake reviews. Each testimonial is tied to a real email address.
Zero friction for clients — no account needed, works on mobile, under 60 seconds to submit
Embed anywhere — works on Webflow, WordPress, plain HTML, Next.js, anything
Free forever — up to 15 testimonials per wall, unlimited walls. Pro plan (€4.99/mo) removes the TestiWall badge.

The tech stack

Next.js 14 (App Router) + TypeScript
Supabase (PostgreSQL + Auth + Storage)
Resend for transactional email
Vercel for hosting
Tailwind CSS for styling

The widget itself is a vanilla JS snippet — no framework dependency, loads async, ~3kb gzipped.

What I learned

The hardest part wasn't the code — it was figuring out the right friction level. Too much verification and clients bounce. Too little and you get spam reviews.

The solution: one email click to verify, no password, no account creation. Completion rate went from ~30% (Google form) to ~78% in my tests.

Try it

testiwall-kappa.vercel.app — free, no credit card.

If you're a freelancer, agency, or SaaS founder who wants real testimonials from real clients without chasing them on LinkedIn, this is for you.

Would love feedback — especially on the embed API and whether you'd want a Zapier/webhook integration for notifications.

Built this in a weekend, deployed on Vercel. Happy to answer questions about the stack.

The problem I was solving

I kept seeing freelancers and SaaS makers lose potential clients because their website had zero social proof. Screenshots look fake. Expensive tools like Testimonial.to charge $50/month — too much for indie projects.

What TestiWall does

Share a collection link with your client
Client submits a testimonial (email-verified)
You approve it, embed the widget on your site

Completely free. No credit card. No limits.

I built a Vinted monitoring bot (Python) — available for hire + source code for sale

Zakaria Zoubai — Sat, 29 Aug 2026 20:47:02 +0000

What I built

I spent the last few months building a Vinted monitoring bot in Python. It:

Monitors Vinted 24/7 with configurable filters (brand, size, max price, keywords, condition)
Sends instant Discord alerts when matching items are listed
Supports multiple search profiles simultaneously
Has a database of 350+ resale niches with buy/sell price targets
Battle-tested, handles anti-bot detection

The business case

Vinted arbitrage is real: buy underpriced items, resell at market price. The bot finds the deals before anyone else.

Example: Nike Air Force 1 listed at 11€ → resell at 45-50€ = ~35€ profit per item.

Available as:

1. Custom bot setup for your account — I configure it with your niches and connect to your Discord.
Price: 200€ (one-time) → Pay via PayPal

2. Web scraping / automation scripts on demand — any Python automation you need.
Price: from 150€ → Pay via PayPal

3. Hire me as freelancer (300€/day, remote, France)
See my full profile: https://riakaza.github.io

Tech stack

Python + Playwright
SQLite + async scanning
Discord webhooks
Configurable niche profiles
