DEV Community: Emanuele Pavanello

I built a GitHub Bot that fixes your code for you (and here's how you can use it)

Emanuele Pavanello — Fri, 06 Jun 2025 09:25:55 +0000

Stop me if you've heard this one before: you're reviewing a pull request and spot a typo. Or maybe you're triaging issues and find a simple bug that needs fixing. You leave a comment, assign the task, and... wait. What if you could just tell a bot to fix it, and moments later, a pull request appears, ready to merge?

That's the reality I wanted to create. I'm excited to introduce FixO Dev Bot, an open-source, AI-powered GitHub bot that automates the tedious parts of coding, so you can focus on what matters.

What is FixO Dev Bot?

FixO Dev Bot is your AI assistant on GitHub. Instead of manually fixing linting errors, refactoring code, or addressing minor bugs, you can simply mention @fixodev in any GitHub issue or PR comment. The bot will then:

Understand the context: It reads the issue description, comments, and even the code itself.
Clone your repository: It securely checks out your code into an isolated Docker container.
Perform the work: The AI analyzes the request and makes the necessary code changes.
Submit a pull request: It delivers the fix directly to your repository in a new PR, or updates an existing one.

Our mission is simple:

To eliminate the friction between identifying code issues and implementing solutions, making high-quality code accessible to every developer and project.

We believe that code quality shouldn't be a luxury, and developers should be free to focus on creative problem-solving, not repetitive tasks.

Why I Built This Bot

As a developer, I've spent countless hours on tasks that felt like they could be automated. Things like:

Fixing a typo across multiple files.
Refactoring a function to be more readable.
Applying linter suggestions.
Updating dependencies.

These tasks, while necessary, are a major source of context switching and a drain on productivity. I envisioned a tool that could act as a pair programmer, taking care of these small but important fixes, allowing me to stay in the flow. That's how FixO Dev Bot was born.

How it Works (The Magic Behind the Curtain)

The magic of FixO Dev Bot lies in its architecture, which is designed for security, efficiency, and intelligence.

When you mention @fixodev, a webhook is sent from GitHub to our server. The server then creates a job and adds it to a queue. A worker picks up the job and spins up a secure Docker container. Inside the container, the bot clones your repository, and an AI agent (powered by models from OpenRouter) analyzes the code and the request to generate the fix. Finally, the bot uses the simple-git library to create a branch, commit the changes, and open a pull request.

The tech stack is built for performance and reliability:

Runtime: Bun + TypeScript
Framework: Hono (for a lightweight server)
Containerization: Docker
AI Integration: OpenRouter
Database: SQLite with Drizzle ORM

Key Features in Action

FixO Dev Bot is more than just a simple "find and replace" tool. It's designed to handle a variety of development tasks.

From Issue to PR in Minutes

Got an issue describing a bug or a small feature? Just mention the bot.

Example: In a GitHub issue

"Hey @fixodev, can you add validation to the email input field in src/components/SignupForm.tsx? It should reject any email that doesn't include an @ symbol."

A few seconds later, you'll get a pull request with the requested changes, ready for your review.

Iterative PR Improvements

The bot can also help you refine existing pull requests. If you see something that needs changing, just add a comment.

Example: In a pull request comment

"@fixodev, great start! Can you also add a unit test for this new validation logic?"

The bot will understand the context of the PR, make the requested changes, and push an update to the same branch. No new PRs, just a clean, iterative workflow.

Custom Configuration (soon)

Every project is different. With a .fixodev.yml file in your repository's root, you can customize the bot's behavior, specifying the runtime, scripts, and more.

runtime: bun:latest
scripts:
  lint: bun run lint
  test: bun run test
  format: bun run format
autofix: true
branches:
  autofix: true
  target: main

How to Get Started

Ready to give it a try? It only takes a minute to set up.

Install the GitHub App for private repositories. It'a not required for public repositories.
(Optional) Add a .fixodev.yml file to your repository for custom configuration.
Mention @fixodev in an issue or PR comment and watch the magic happen!

Join the Community and Contribute

FixO Dev Bot is an open-source project, and we believe the best tools are built by the community. Whether you're a developer, a designer, or just someone with great ideas, we'd love for you to get involved.

Here are a few ways you can contribute:

Beta Testers: Try the bot on your projects and give us feedback.
Developers: Help us fix bugs, add new features, and improve performance.
Documentation: Help us improve our guides and tutorials.

Ready to jump in? Check out the project on GitHub and join our Discord community to get started.

Conclusion

My goal with FixO Dev Bot is to build a tool that feels like a natural extension of your development workflow—an AI partner that handles the grunt work so you can focus on building amazing things.

I'm incredibly excited to see what the community builds with it. Give it a try, and let me know what you think!

Introducing Avatarify AI: the AI-powered profile photo generator

Emanuele Pavanello — Thu, 02 Feb 2023 17:45:26 +0000

Are you tired of having the same old boring profile photos? Look no further, Avatarify AI is here to revolutionize the way you present yourself online. Developed by independent developer Emanuele Pavanello, Avatarify AI is an open-source SaaS that uses AI to generate custom profile photos based on your desired look.

To get started, simply log in with your Google account or use a magic link. Upload at least 10 photos of yourself from different angles and watch the AI do its magic. The AI model, based on the recently open-sourced "Stable diffusion" model, will learn your unique features and generate up to 100 custom profile photos for you to choose from. The model is capable of recognizing and generating photos for Man, Woman, Couple, Dog, Cat, and Child.

But that's not all. Avatarify AI takes it a step further by allowing you to customize the style and theme of your generated photos. With inspiration from the prompts available on lexica.art, the possibilities are endless. All you need to do is pay a one-time fee of €9.99 (currently 40% off with promo code LESS40) to get started.

The frontend of Avatarify AI is written in Svelte and TypeScript in strict mode, and the TypeScript types related to the database are automatically generated using the Supabase CLI. The authentication, user data, and photo storage are managed through Supabase to avoid manual backend and database management. The project is continuously integrated with Vercel pipelines.

So what are you waiting for? Give Avatarify AI a try and let the AI help you stand out from the crowd. The project is open source, and the developer is actively looking for engagement through stars, issues, and pull requests on GitHub.

No more rest 🚀

Emanuele Pavanello — Mon, 15 Feb 2021 23:55:10 +0000

Hello guys!

Here the GitHub Repo and here the NPM package 📦

If you, like me, don't like to pass all day defining new rest API and calling them from the frontend in a verbose way, you can start to use my new NPM package no-more-rest that allows you to expose your API directly from your server to be called transparently from your client with the IntelliSense support.

If you like the idea star the project and collaborate with me 💗

A small example of the potential

// server/myApi.js

export function doLogin(username, password) {
  return username == "admin" && password == "admin";
}

export function getLoggedUsers() {
  return ["Elon Musk", "admin"];
}

// server/server.js

import express from "express";
import { expose } from "no-more-rest";

import * as myApi from "./myApi";

const app = express();
expose(app, myApi);

app.listen(8000);

Add this npm script to your package to generate the proxy script for the client from the exposed module

"scripts": {
   "sync-api": "no-more-rest --input myApi.js --output-dir ../your-client-path/ --watch"
}

Import in the client your generated proxy and use it as if it were on your backend.

// client/index.js

import { doLogin, getLoggedUsers } from "./generatedProxy";

doLogin("admin", "admin")
  .then((result) => {
    if (result) {
      alert("Login success");

      getLoggedUsers().then((users) => {
        alert("The logged users are: " + users.join(", "));
      });
    } else {
      alert("Login failed");
    }
  })
  .catch(() => {
    alert("Network error");
  });
