Even though AI helps a lot, developers still need to watch out for security and who owns the code.
Keeping up with new AI developments will help developers use these tools better.
1. GitHub Copilot
GitHub Copilot has really changed how a lot of us write code. It’s like having a coding buddy right there in your editor, suggesting lines or even whole functions as you type. It’s built on OpenAI’s models, which means it’s pretty good at understanding what you’re trying to do, even if you just leave a comment explaining it. I’ve found it particularly helpful for boilerplate code or when I’m working with a new library and don’t remember the exact syntax.
It works with a bunch of popular editors like VS Code, Visual Studio, and JetBrains IDEs, and supports many languages, including Python, JavaScript, and Go. The suggestions are usually pretty relevant, and you can cycle through different options if the first one isn’t quite right. It also has a chat feature now, which is handy for asking questions about your code or getting help debugging.
Here’s a quick look at what it offers:
Code Suggestions: Completes lines or entire functions based on context and comments.
Chat Interface: Ask questions, get explanations, and debug directly within your IDE.
IDE Integration: Works smoothly with major development environments.
Multi-Language Support: Handles a wide array of programming languages.
While it’s a huge time-saver, it’s not perfect. Sometimes it can suggest code that’s a bit off, or even duplicate code it’s seen elsewhere. For beginners, it’s important to review the suggestions carefully. It’s also a paid service, though the individual plan isn’t too expensive.
Copilot is best thought of as a pair programmer that can sometimes be a bit too eager to finish your sentences, but is generally helpful when you guide it correctly. It’s not a replacement for understanding code, but a tool to speed up the process of writing it.
2. ChatGPT
So, ChatGPT. It’s probably the one most people have heard of, right? It’s like the friendly chatbot that got really, really smart. You can just talk to it, ask it to write code, explain what some confusing snippet does, or even help you find bugs. It’s built by OpenAI, and it uses their big AI models, like GPT-4 and the newer GPT-4o. Think of ChatGPT as the easy-to-use door to these powerful AI brains.
It’s pretty good at just spitting out code when you ask for it. Need a Python script to sort some files? Just ask. Want a basic HTML structure for a webpage? It can do that too. The real magic, though, is when you start asking it to explain things. It can break down complex algorithms or tell you why your code isn't working, which is super helpful when you’re stuck.
Here’s a quick look at what it’s good for:
Generating code snippets for specific tasks.
Explaining existing code, line by line if needed.
Debugging errors and suggesting fixes.
Translating code between different programming languages.
Writing documentation for your code.
It’s not perfect, of course. Sometimes the code it writes might have small errors, or it might not quite grasp the full context of a huge project. You still need to check its work, especially for anything critical. But for getting started, learning, or just speeding up everyday coding tasks, it’s a solid tool.
You can interact with ChatGPT through its website, and there are different versions. The basic version is free, which is pretty amazing. If you want access to the most advanced models and faster responses, there’s a paid subscription, ChatGPT Plus, that costs $20 a month. They also have a Pro Mode, which is more expensive, but that’s for people doing really heavy-duty stuff.
It’s a tool that’s constantly getting updated, so what it can do today might be even better tomorrow. Definitely worth playing around with if you code at all.
3. Cursor
Cursor is an AI-powered code editor that really feels like a step up for developers who want to work more closely with their code using natural language. It’s built on the familiar VS Code foundation, which is a big plus, but it layers on some pretty smart AI features. Think of it as having a super-powered assistant right inside your editor.
One of the standout features is what they call Copilot++, which is designed to predict your next code edit. It’s not just about suggesting the next line; it seems to get a sense of what you’re trying to achieve and offers more substantial code blocks. Then there’s Cmd-K, which lets you modify code just by typing what you want to happen. It’s pretty wild to just describe a change and see it appear.
Cursor also tries to streamline your workflow in other ways. It can help with things like finding unused variables or suggesting ways to prevent errors before they even happen. For teams, it offers AI code reviews and can even generate documentation, which is a huge time-saver.
Here’s a quick look at what it offers:
Intelligent Coding: AI suggestions, natural language commands, and debugging help.
Workflow Streamlining: Real-time code optimization and error prevention.

It integrates right into your workflow, working with VS Code, JetBrains IDEs, and even your terminal.
What really sets Qodo apart is its multi-agent approach, tackling different parts of development with specialized AI. For instance, I used Qodo Gen to generate test cases for a function in a computer vision project. It whipped up a couple of solid tests, checking for valid inputs and handling cases where a parameter was missing. The AI chat feature also helped me clean up code and add documentation, which was pretty handy.
When it comes to pull requests, Qodo Merge is where it's at. You can use commands like /describe to get automatic PR descriptions, /ask to query specific code sections, /improve for optimization tips, and /review for a full analysis. I tried the /review command on a pull request, and it gave me an estimate of the effort involved, pointed out what the PR was focused on, and even flagged a potential security issue like an exposed API key. It also suggested removing redundant tests.
Here’s a quick look at what Qodo offers:
Code Generation & Testing: Qodo Gen creates code and unit tests.
Test Coverage Improvement: Qodo Cover helps ensure your tests are thorough.

While the "extended thinking" feature is a game-changer for understanding, it's not available on the free tier. Still, for anyone serious about integrating AI into their workflow, Claude 3.7 Sonnet offers a compelling blend of speed, detail, and developer-focused capabilities.
6. CodeGPT
CodeGPT is an interesting option if you're looking for an AI coding assistant that really digs into your project's context. It's not just about spitting out code snippets; it builds this internal knowledge graph of your entire codebase. Think of it like it's creating a map of your project, understanding how different parts connect and where symbols are used. This means its suggestions are usually pretty relevant to what you're actually working on.
One of the big pluses here is its flexibility with different AI models. You can hook it up to OpenAI, Claude, Gemini, Mistral, or even run local models if you've got them set up. This is great because you're not locked into one provider, and if you're concerned about privacy or have sensitive code, running things locally is a solid option. It also plays nice with a bunch of editors like VS Code and JetBrains IDEs, which is handy.
CodeGPT also has this neat 'agent ecosystem'. These are basically pre-built tools that use AI for things like code reviews, generating tests, or writing documentation. They even have helpers for specific frameworks like Laravel or Next.js. It’s like having a small team of specialized AI helpers ready to go.
Setting up CodeGPT can take a bit more effort than just installing a simple plugin. You'll need to install the extension, get your API keys sorted, and maybe even set up local model servers if that's your plan. Plus, the free version has limits, so if you need access to private repos or more advanced features, you'll likely need to pay up.
Here's a quick look at its pricing structure:
Free: $0/seat/month (basic features)
BYOK: $7.20/seat/month (billed annually, Bring Your Own Key)
Teams: $30/seat/month (billed annually)
For Business: Custom pricing
I was messing around with it the other day, trying to get a handle on some code I didn't write. CodeGPT sat right there next to my editor, explaining the logic as I went. It wasn't just telling me what the code did, but seemed to grasp the intent behind it. It made understanding the flow much easier, especially when dealing with unfamiliar code.

9. Qwen3-Coder (Unsloth)
Alibaba's Qwen3-Coder, especially when paired with Unsloth's optimizations, presents a compelling option for developers prioritizing local control and extensive context handling. This model is built for agentic coding workflows, meaning it can read your code, generate edits, write tests, and even fix bugs based on natural language prompts or scripts. It's designed to work offline, which is a big plus for security-conscious environments or when you just don't want to rely on an internet connection.
One of the standout features is its massive context window, potentially reaching up to 1 million tokens. This allows it to process very large codebases or long conversation histories without losing track of what's important. Unsloth's contribution comes in the form of efficient quantization, using 2-8 bit dynamic quantization with GGUF formats. This makes it possible to run Qwen3-Coder on standard GPUs and CPUs, balancing performance with manageable memory use.
Running Qwen3-Coder locally does require some setup. You'll need to consider things like quantization configuration and selecting the right GGUF files. It doesn't come with native IDE integration, so you'll likely need to use it with tools like Continue.dev or Aider to get it working smoothly within your editor.
Qwen3-Coder is entirely free and open-source, making it accessible for both individual developers and organizations without cost barriers, while also offering flexibility in deployment through widely supported tooling.
For instance, I tested it by asking it to generate a Bash script for backing up folders. It successfully created a script that accepted parameters for source and destination, included error handling for missing directories, and used timestamped naming for the zip files. It even opted for zip over tar for better cross-platform compatibility. This kind of task shows its practical application for automating development routines. You can find more details on how to run it and its quantization benchmarks on Unsloth's resources.
Key advantages include:
Agentic coding capabilities for automated tasks.
Very large context windows for handling big projects.
Efficient local deployment through Unsloth quantization.
A local-first architecture for privacy and offline use.
While it requires a bit more manual configuration than some cloud-based solutions, the flexibility and control offered by Qwen3-Coder (Unsloth) make it a powerful tool for many developers.

Gemini CLI is Google's take on bringing AI directly into your terminal. It's an open-source agent that uses Gemini models to help with coding tasks, but it can do more than just write code. Think of it as a smart assistant for your command line. It works by figuring out what you want, then using tools to get it done. This means it can search for code, help with documentation, and even work with other tools for things like image generation.
One of the standout features is its massive context window, thanks to Gemini 2.5 Pro. We're talking about a million tokens, which is huge for looking through large codebases. Plus, the free tier is pretty generous, giving individuals a lot of requests each day. It also comes with built-in tools like grep and file editing capabilities, and since it's open source, you can tinker with it or even host it yourself.
However, it's still in preview, so things might change, and it doesn't have super deep integration with IDEs like some other tools. Some users have mentioned it can be a bit slow sometimes or make mistakes with file edits.
I tried using Gemini CLI to check a Node.js file that handled transactions. It quickly summarized what the file did and pointed out some serious security issues. It found an unused module, a hardcoded internal token, and a dangerous use of eval(). What was really helpful was that it didn't just list the problems; it explained why they were problems, making it easy to fix them and secure the code.
Here's a quick look at its capabilities:
Code Analysis: Identifies potential bugs and security vulnerabilities.
Documentation: Assists in generating or understanding code documentation.
File Operations: Can read, write, and search within files directly from the terminal.
Web Search: Integrates with Google Search to ground its responses.
Gemini CLI is a powerful tool for anyone who spends a lot of time in the terminal and wants to bring AI assistance directly into their workflow. Its open-source nature and generous free tier make it accessible for many developers.
