I Built an AI SEO Content Generator — Generate 2000-Word Articles in 60 Seconds

mocsa03 — Wed, 18 Mar 2026 04:49:41 +0000

Content marketers and bloggers spend hours writing SEO-optimized articles. I built WriteKit to cut that down to 60 seconds.

What WriteKit Does

You enter a keyword and select your preferences:

Article type: Blog post, product review, how-to guide, or listicle
Language: English, Chinese, Japanese, or Korean
Word count: 1,500 to 3,000 words
Tone: Professional, casual, academic, or friendly

Hit "Generate" and get a complete, SEO-optimized article with:

SEO title with your target keyword
Meta description (150-160 characters)
Structured H2/H3 headings
Natural keyword density (3-5 mentions)
Internal linking suggestions

The Tech Stack

Layer	Technology
Framework	Next.js 14 (App Router)
AI Engine	OpenAI GPT-4o-mini
Auth	NextAuth.js (GitHub + Google)
Database	Supabase (Postgres)
Payments	LemonSqueezy
Deployment	Vercel

How the AI Generation Works

The core is a carefully crafted prompt that instructs GPT-4o-mini to:

Research the topic thoroughly
Structure the content with proper heading hierarchy
Include the target keyword naturally
Write in an engaging, human-like tone
Add internal linking anchor text suggestions

The response streams in real-time using ReadableStream, so you see the article being written character by character — like watching a fast typist.

Pricing

Free: 1 article/day, 1,500 words max, English only
Pro: $19/month — Unlimited articles, 3,000 words, all languages
Business: $49/month — Everything + API access + bulk generation

How I Built a Complete SaaS in 3 Days Using My Own Boilerplate

mocsa03 — Wed, 18 Mar 2026 02:29:19 +0000

Every time I start a new SaaS project, I waste 2-3 weeks rebuilding the same infrastructure:

Authentication (GitHub, Google, email/password)
Payment processing (subscriptions, webhooks, billing portal)
Dashboard (sidebar navigation, stat cards, settings)
Database schema (users, plans, billing)
Deployment configuration

So I built ShipKit — a production-ready SaaS starter kit that lets you skip straight to building your product.

What's Inside

ShipKit is a complete Next.js 14 codebase with everything a SaaS needs:

Authentication (3 providers, zero config)

// GitHub, Google, and Email/Password — all wired up
// Just add your API keys to .env.local
GITHUB_CLIENT_ID=your_id
GOOGLE_CLIENT_ID=your_id

NextAuth.js handles the heavy lifting. JWT sessions, provider callbacks, account linking — it's all there.

Payments (LemonSqueezy integration)

Subscription checkout with one API call
Webhook handler for subscription lifecycle events
Billing portal for customers to manage their plans
Supports PayPal, Apple Pay, Google Pay

Dashboard

A beautiful dark-theme dashboard with:

Sidebar navigation
Stat cards
Settings page
Billing management
Responsive design

Database (Supabase)

Postgres with instant APIs
Migration files ready to run
User management schema
Plan and billing data structures

The Tech Stack

Layer	Technology
Framework	Next.js 14 (App Router)
Language	TypeScript
Styling	Tailwind CSS
Auth	NextAuth.js
Database	Supabase (Postgres)
Payments	LemonSqueezy
Deployment	Vercel

5-Minute Setup

# 1. Download and extract
unzip shipkit.zip -d my-saas

# 2. Install dependencies
cd my-saas && npm install

# 3. Configure environment
cp .env.example .env.local
# Edit .env.local with your API keys

# 4. Run database migration
# Paste SQL from supabase/migrations/001_init.sql into Supabase SQL Editor

# 5. Start building
npm run dev

Your SaaS is running at http://localhost:3000 with auth, payments, and dashboard fully functional.

Live Demo

Why Not Use Other Alternatives?

I've tried ShipFast, SupaStarter, and others. They're great, but:

ShipKit uses LemonSqueezy instead of Stripe — global coverage, PayPal support, handles sales tax automatically
3 auth providers out of the box — most alternatives only include OAuth
Supabase instead of raw Postgres — instant APIs, real-time, and a generous free tier
No external dependencies for password hashing — uses Node.js built-in crypto (pbkdf2)

Pricing

Starter: $99 (1 project license)
Pro: $199 (unlimited projects + 6 months updates)
Enterprise: $399 (lifetime updates + priority support)

One-time purchase. No subscriptions. No recurring fees.

60 Free Developer Tools You Didn't Know You Needed

mocsa03 — Tue, 17 Mar 2026 08:34:45 +0000

As developers, we constantly reach for small utility tools — a JSON formatter here, a Base64 encoder there, a UUID generator when we need a quick ID. Most of us have bookmarks scattered across dozens of different websites.

I got tired of this and built FastDevKit — a single site with 60 free developer tools, all running entirely in your browser. No server processing, no data collection, no signups.

Why Client-Side Only?

Every tool on FastDevKit processes data locally. Your code never leaves your browser. Here's why:

Privacy — I don't want to see your JWT tokens or API keys
Speed — No network round-trips, instant results
Offline — Works without internet once cached
Cost — Static hosting = free forever

The Tool Collection

Encoding & Decoding

JSON Formatter — Format, validate, and minify JSON with syntax highlighting
Base64 Encoder/Decoder — Text and file encoding
URL Encoder/Decoder — Handle query strings and URI components
JWT Decoder — Inspect token headers, payloads, and expiration
HTML Entity Encoder — Encode/decode special characters
Image to Base64 — Convert images to data URIs

Generators

UUID Generator — Bulk generate v4 UUIDs
Password Generator — Cryptographically secure random passwords
Hash Generator — SHA-1, SHA-256, SHA-384, SHA-512
QR Code Generator — Generate and download QR codes as PNG
Lorem Ipsum — Paragraphs, sentences, or words
Meta Tag Generator — Complete HTML + OG + Twitter Card meta tags

Formatters & Minifiers

SQL Formatter — Keyword uppercasing and indentation
CSS Minifier/Beautifier — Compress or expand CSS
JavaScript Minifier — Strip comments and whitespace
HTML Prettifier — Format messy HTML

Converters

Timestamp Converter — Unix epoch to human-readable dates
Color Picker — HEX, RGB, HSL conversion
JSON to CSV — Bidirectional conversion
YAML to JSON — Config file format conversion
JSON to TypeScript — Auto-generate interfaces
SQL to MongoDB — Query syntax translation

Web & SEO Tools

CSS Flexbox Generator — Visual layout builder
CSS Grid Generator — Visual grid editor
Open Graph Debugger — Preview social sharing cards
HTTP Headers Analyzer — Security header checker
Crontab Guru — Natural language cron explanations

...and 30+ more tools covering regex testing, diff checking, Markdown preview, chmod calculator, and beyond.

Tech Stack

Next.js 14 with static export (zero server costs)
Tailwind CSS for the dark theme UI
Vercel free tier for hosting
4 languages: English, Chinese, Japanese, Korean
287 routes total

Total infrastructure cost: $0/month.

What I Learned

Next.js static export + i18n requires creative routing with [locale] dynamic segments
JSON-LD structured data on each tool page actually improved Google indexing speed
Having 60 focused pages with proper SEO beats having one mega-page
Tailwind's dark mode with a consistent color palette (#0f1117 background) creates a professional dev-tool feel

Every tool is free, no signup required. If you find it useful, I'd love to hear which tools you use most — it helps me prioritize what to improve next.

I also built FormCatch — a form backend service that lets you add contact forms to static sites without writing server code. Free tier available.

I Built a Form Backend So You Never Have to Write Server Code for a Contact Form Again

mocsa03 — Mon, 16 Mar 2026 13:21:14 +0000

Every time I built a static site or landing page, I ran into the same annoying problem: handling form submissions.

I'd either set up a whole Node server for one endpoint or hack together a Lambda function that I'd inevitably forget about.

So I built FormCatch — a form backend that works with plain HTML.

How it works

Sign up with GitHub
Create a form endpoint (takes 5 seconds)
Set your HTML form's action to the endpoint URL
Done. Submissions flow in.

<form action="https://formcatch.vercel.app/api/f/your-endpoint" method="POST">
  <input type="text" name="name" placeholder="Name" required />
  <input type="email" name="email" placeholder="Email" required />
  <textarea name="message" placeholder="Message"></textarea>
  <button type="submit">Send</button>
</form>

No SDK, no npm package, no JavaScript required. Just HTML.

Features

Email notifications on every submission
Spam protection (honeypot + reCAPTCHA)
CSV export for all submissions
Full CORS support (works with React, Vue, static HTML, anything)
Custom redirect URLs after submission
API access for programmatic integrations
Dashboard to view and manage all submissions

Pricing

Free: 1 endpoint, 50 submissions/month
Pro ($12/mo): 10 endpoints, 1,000 submissions/month
Business ($29/mo): Unlimited endpoints, 10,000 submissions/month

Tech Stack

Built with Next.js, Supabase (PostgreSQL), Resend for email delivery, and deployed on Vercel.
