I built a free AI Regex & SQL Generator to save developers time (no login, open models)

🚀 Why I built this

Like most developers, I’ve spent way too much time searching for that one regex pattern that works.
And writing SQL queries from scratch every time can get repetitive too.

So, I decided to create a simple, AI-powered developer tool that can do both — instantly.

👉 Dev Brains AI

It’s a collection of free AI tools that help developers save time on everyday coding tasks.

🧩 Current tools on the site
🔹 AI Regex Generator

Describe what you want — and it writes the regex (with explanation).

Examples:

“match a valid email address”

“extract numbers from a string”

“check if string starts with ‘abc’”

Result → regex + human-readable explanation.

Try it here:
➡️ https://dev-brains-ai.com/regex-generator

🔹 AI SQL Query Generator

Write your query in plain English, and it outputs real SQL instantly.

Examples:

“Select top 5 users by revenue”

“Find all orders from last 30 days”

It supports MySQL, PostgreSQL, and SQLite-like syntax.

Try it here:

🧠 How it works

I used:

Next.js + TailwindCSS for the UI

Open-source AI models from Hugging Face (no paid API keys)

Node.js serverless functions for generation

Deployed on Vercel (super fast and free)

Each request uses a small, open model that runs under 2 seconds, so you get results instantly.

💡 What’s next

I’m working on adding:

🧾 JSON formatter with AI explanations

🪄 Code comment generator

⚙️ Log pattern detector for DevOps users

If you have ideas for more tools, I’d love to hear them in the comments.

⚡ TL;DR

Free AI-powered Regex & SQL Generators

No signups, no limits

Uses open models (not OpenAI API)

Fast and ad-supported

❤️ Feedback welcome

If you test it, I’d really appreciate your feedback on:

Accuracy of regex/SQL outputs

UI/UX experience

What AI tools you’d find most useful next

📬 Want to build similar tools?

If anyone’s curious about the tech stack or Hugging Face integration, I can share a tutorial on setting up AI inference endpoints in a free-tier Next.js app.

That’s it — hope you find it useful!

Happy coding 💻
