— My stack · tested daily

My stack,
from basic
to advanced.

No sponsorships, no "top 20 best." Just the tools I actually open to run my AI projects, my site, my newsletters. 7 essentials to get started, plus 4 advanced ones for when a project actually calls for them. And right at the bottom, 2 bonus picks with affiliate links — I'll flag them clearly first.

01
— The central tool
Claude Code Max $200/month

The brain of my whole stack. Claude Code is Anthropic in your terminal. It reads your files, writes code, runs commands, fixes its own mistakes. I've used it 6 to 8 hours a day for six months · not an exaggeration, I've actually measured it.

Why this one
The Max version (the $200 plan) gives you priority access to the Opus and Sonnet models, with token limits that even heavy use never hits. For an entrepreneur using it every day, it pays for itself in 48 hours of saved time.
Setup
Download the app at claude.com/download. Double-click, sign in with your Anthropic account, go.
How I use it
Writing articles, maintaining this site, automation scripts (newsletter, brainstorming, social-poster), debugging, research, SEO audits. It does all of it.

02
— The missing link
dev-browser Free

A windowless browser your AI drives by writing a tiny script. You ask Claude to go to a page, scrape it, test it, screenshot it · and it does. Without you opening Chrome by hand, without you writing the code.

Why this one
Claude knows a ton of pages from its training, but it doesn't know recent pages and can't interact with them. dev-browser opens a real Chromium instance in the background, and Claude sends it commands. The result: you can ask Claude "check that my page is up to date" or "fill out this form and tell me what happens." Magic.
Setup
Ask Claude Code "install dev-browser for me." It'll give you the up-to-date command (usually via npm install -g).
How I use it
Checking after every deploy that the site is responding · scraping a source for an article · testing the newsletter form locally · taking screenshots during UI redesigns. I call it 5 to 10 times a day through Claude.

— Frictionless hosting
Vercel Free for you

You push code to GitHub, Vercel deploys it on its own in 30 to 45 seconds. No more server, no more needing to know what a server even is. My entire site runs on Vercel, for free. You can too.

Why this one
The Hobby plan (free) is plenty for a personal site, a blog, a landing page, a newsletter. Generous bandwidth, unlimited deploys, custom domain supported. No credit card asked until you go over. Perfect to start.
Setup
Create an account at vercel.com (free, 30 seconds), connect your GitHub account, click "Import Project." Vercel detects the framework, builds, deploys. Done.
How I use it
I deploy this site on every git commit. My newsletter endpoint (/api/subscribe.js) runs as a Vercel serverless function. I've never had to touch the infra. Zero maintenance.

04
— Email sending built for devs
Resend Free up to 3k/month

The service I use to send my newsletters and manage my subscribers. Dead-simple API, clean interface, detailed logs, none of the Mailchimp-style bloat. 3,000 free emails a month, more than enough to start.

Why this one
Resend is built for devs (and so for our AIs coding on our behalf). One API key, 3 lines to send an email, a clean audience editor, clear stats. No marketing gimmicks, zero upsell. The free plan is genuinely usable · not bait like most of the competition.
Setup
Account at resend.com, verify your sending domain (simple DNS), generate an API key. You hand the key to Claude, it writes the integration code for you.
How I use it
I keep my "Amazon Sellers" audience (119 contacts) hosted on Resend. My Vercel endpoint /api/subscribe adds each new subscriber automatically. I send my Friday newsletter from the web interface.

— No-code automation
n8n Free self-hosted · $20/month cloud

The equivalent of Zapier or Make, but open-source and self-hostable. You connect services together by dragging and dropping blocks. Perfect when you want your AI to trigger a cascade of actions across 3 or 4 tools without writing code.

Why this one
Unlike Zapier, which charges per action, or Make, which charges per operation, self-hosted n8n is free with unlimited use. You only pay for your server ($5/month at Hetzner or free on Railway). And if you'd rather not self-host, n8n Cloud at $20/month does the job with no limits.
Setup
Easy option: account at n8n.io, cloud plan at $20. Budget option: a $5/month VPS + ask Claude "install n8n on my VPS." It holds your hand the whole way.
How I use it
Automating workflows that touch several services (Gmail → CRM → Slack → Notion). I'm not running it at full tilt yet — I prefer my own Claude Code scripts — but n8n shines the moment you want to wire 4-5 third-party tools together.

— The terminal that won't put you off
Ghostty Free

A modern, open-source, super-smooth terminal. Ghostty is where I launch Claude Code every day. Compared to the default Apple Terminal (which works, but feels like 2005), it's night and day.

Why this one
The Apple Terminal is ugly but functional. Ghostty is just as simple, but with crisp colors, vector font rendering, and modern behavior. Zero manual configuration · you open it, you use it. For someone who spends 8 hours a day in a terminal, that changes everything.
Setup
Download at ghostty.org (Mac only for now · Linux coming). Double-click, drag into Applications, open. That's it.
Alternative
If you want a version with AI built right into the terminal, Warp (paid, $20/month) is richer. But for a non-dev just launching Claude Code inside it, Ghostty is more than enough and it's free.

— The database with no server to manage
Supabase Free < 500 MB

The moment your site, your form, or your agent needs to store data (users, responses, leads, long-term memory), you need a database. Supabase is the simplest on the market for a non-dev · a clean web interface, a serious free plan, no server to administer.

Why this one
Unlike MongoDB, MySQL or PostgreSQL that you have to host yourself, Supabase gives you a managed PostgreSQL database in the cloud with authentication, file storage and serverless functions · all in the same dashboard. The free plan holds 500 MB of data and 50,000 monthly active users · plenty to run a first project or an MVP.
Setup

1. Free account at supabase.com (GitHub or email, 20 seconds).

2. Create a project · pick a region near you (Paris if you can).

3. Grab your URL + API key in Project Settings → API.

4. Hand it all to Claude Code · "connect this project to Supabase, create a subscribers table with email and date." It installs the library and writes the code.

How I use it
In the Eurofiscalis projects, Supabase stores qualification forms, inbound leads, AI agent sessions. For my personal site I don't need it yet (everything's static), but the moment I add a comment system, a feedback database, or long-term memory for an agent · it'll go through Supabase.
Who it's for
The moment your site goes from a "brochure page" to an "app that remembers something." A form that saves responses, a newsletter with segments, an agent that recalls past conversations · Supabase is the storage link.

— Part 2 · Advanced stack

4 tools to go further.

These 4 tools aren't in the base stack · you don't need them until you've got a specific use case that calls for them. I'm showing them anyway, because I use all of them for real projects, and because you'll inevitably run into them if you dig into AI or content.

Sanity if you want a real CMS for a multi-language blog. Zernio if you post regularly on social. fal.ai if you generate images or videos with AI. Remotion if you want to automate programmatic videos.

My rule · I never install a tier-2 tool until I've got a project that's hit a wall on a tier-1 limit. If you just want to test something, do it somewhere other than your production stack.
Advanced tool Role Price When to add it
Sanity Headless CMS (structured content) Free up to 3 users When your site needs a real multi-language blog
Zernio Social post scheduler €20 to €50/month by volume When you post on 2+ networks every week
fal.ai API to generate AI images and videos Pay-as-you-go (a few cents per generation) When you want automated visuals in your workflows
Remotion Programmatic videos (code → video) Free for solo use When you want to generate 50 reels with one script
08
— The headless CMS
Sanity Free < 3 users

A real CMS for managing structured content · articles, pages, categories, authors. The interface is clean, the API is excellent, and you keep control over presentation (Sanity forces no design on you). I use it for the Eurofiscalis blog · 7 languages, 14 categories, articles translated through a single metadata reference.

When to add it
When you pass ~20 articles on your site and start thinking *"I'd love an interface to manage this without touching the code."* Or if you've got serious multi-language needs (3+ languages). Below that, a simple articles/ folder in Markdown is enough.
Getting started
Account at sanity.io. Create a project via their CLI (npm create sanity@latest). Claude Code holds your hand on the data schema. The free plan covers 3 users + 10,000 documents.
How I use it
Eurofiscalis blog · 7 Belgium articles in draft (6 translations + 1 original), taxonomies published, reproducible MD → Sanity pipeline. Not used for this personal site yet · too lightweight to justify it.

09
— The social scheduler
Zernio €20 to €50/month

A French SaaS to schedule and publish on LinkedIn, X, Instagram, Threads from a single interface. Clean API (I built an integration into my back-office), enough stats, fair pricing. An alternative to Buffer or Hootsuite, cheaper and simpler.

When to add it
When you post regularly on 2+ networks and spend more than 30 minutes a week doing it by hand. Below that, Claude + manual copy-paste is enough.
Getting started
Account at zernio.com. Connect your networks, plan at €20/month for 2 networks, €50/month for all 4. API available with a Bearer key · I integrated it into my back-office to publish from my drafts.
How I use it
My back-office generates LinkedIn and X drafts from each published article via a "Social-poster" button. I review, schedule it in Zernio, and the rest is automatic.

— The AI API for visuals
fal.ai Pay-as-you-go

A platform that exposes dozens of AI models to generate images, videos, voice, animations · all behind one unified API. Infinitely simpler than wiring together Replicate, RunPod or HuggingFace by hand. Usage-based pricing, a few cents per generation depending on the model.

When to add it
When you want to fold AI image or video generation into an automated workflow. For one-off use (a blog image a week), Midjourney directly or ChatGPT image is enough.
Getting started
Account at fal.ai, $10 in free credits. API key in the dashboard. Claude Code can call the API directly · you ask it "generate a Flux image with this prompt," it codes the call.
How I use it
In the Leo Reels Pipeline project (planned for the Eurofiscalis newsletter) · generating video avatars via Hedra + voices via ElevenLabs, assembled by Remotion. fal.ai orchestrates part of the image pipeline.
Try fal.ai ↗
11
— Programmatic videos
Remotion Free (solo use)

Write a video in code (in React, actually) · text, images, animations, transitions. Remotion exports the final video as MP4. The only serious way to generate 50 variants of a reel with one script. Free for personal use, paid if you use it in a commercial product with more than 3 developers.

When to add it
When you want to industrialize short-video production (IG reels, TikTok) with dynamic content · title, captions, B-roll changing on every version. For a one-off video, CapCut or Descript are plenty.
Getting started
npx create-video in your terminal creates a project. You write your video in JSX, run npm start to preview, npm run build to export. Claude guides you, especially if you've never touched React.
How I use it
A crucial part of the Leo Reels Pipeline · Remotion takes the ElevenLabs voice scripts + the Hedra avatars + the fal.ai visuals and assembles reels ready to publish via Zernio. A 1-click pipeline = 5 scheduled reels.

What's not on this list (on purpose)

I use plenty of other tools in my Eurofiscalis and personal projects. But I'm not going to pad this page to please the SEO gods. Here's what I also use, but that I don't recommend you look at until you've mastered the 6 above:

My rule: never add a tool to your stack until you've hit a real limit on the previous one. 90% of the entrepreneurs I see have too many tools and not enough clients. The tool comes after the need.

💛 Bonus · Transparency

2 more tools,
with openly affiliate links.

Up to here, everything you've read had no affiliate link at all. I wanted to keep it clean. But there are two tools I use every single day that genuinely changed my life — so I'm giving them their own clearly visible section to share them with you.

My pact with you. The two links below are affiliate links. If you sign up through my link, it earns me a small commission, without a single cent more out of your pocket. I ONLY put tools here that I actually open every day. If one of the two is no use to you, skip it, that's fine.

— The password manager
Dashlane Affiliate link

Between Claude Code, Supabase, Resend, Vercel, Stripe, Cloudflare, Sanity… I'm managing well over twenty API keys at any time. Plus the family's personal passwords. Before Dashlane, I kept them in a Notes file, or clicked "forgot password" five times a week. Never again.

What it does
A password manager that lives in your browser and on your phone. It autofills everything, generates strong passwords, and also stores API keys, 2FA codes, and sensitive documents. End-to-end encryption, so no one at Dashlane can read your data.
Who it's for
Anyone with more than 10 online accounts — so everyone in 2026. Even more so if you use Claude Code and juggle API keys every day.
How I use it
I open it 20 times a day without thinking about it. Secure sharing turned on with Kevin for the Eurofiscalis work accounts. Zero reused passwords, zero lost keys. One less thing to stress about.

— AI dictation
Wispr Flow Affiliate link

You talk, your text appears on screen — in any app. Browser, Claude Code, email, Notion. The AI cleans up the ums, adds punctuation, rephrases when you stumble. I dictate my Claude prompts, I dictate my article drafts, I dictate my newsletter replies. I type three times less than before.

What it does
Press a shortcut, talk, release. The text appears wherever your cursor was. Works flawlessly in French. You can even dictate long prompts to Claude Code without ever touching the keyboard.
Who it's for
Anyone who writes a lot — articles, emails, prompts. If you type with two fingers, even more so. If you walk during your calls and want to dictate notes after, even more so.
How I use it
I dictate my LinkedIn post ideas on the walk to pick up my son from school. I dictate my Claude Code prompts when my hands are deep in a project. Huge time savings from day one.
