My Experience with Replit

My experience with Replit was truly impressive and eye-opening. The sign-in process was seamless, and I used their free version to build a complete men’s clothing app from scratch. The AI agent intelligently analyzed my prompt, processed it, and generated the full application, including the complete code and file structure.

What amazed me the most was its ability to detect and fix errors automatically. When an issue arose during execution, the AI agent analyzed the error, identified the relevant code file, updated the code accordingly, and then re-ran the application.

The most exciting part was that Replit not only built the backend, database, and frontend but also executed the application using the necessary commands. This resulted in a well-structured app with functional buttons, working use cases, and an aesthetically pleasing UI-easily customizable to fit personal preferences. Additionally, Replit offers the option to deploy the application effortlessly. Here is the prompt I used: “Design and develop a sleek, user-friendly app for a men’s clothing brand that offers personalized style recommendations, virtual try-ons, easy browsing by categories, and seamless shopping with secure checkout.”

This is how the Replit playground looks, with the chat box on the left and the frontend design of my application on the right:

My Experience with Cursor

I found Cursor to be a fascinating tool, so I decided to put it to the test by developing a full web application. I provided a simple prompt: “Create a web application just like a classroom, where students and teachers can interact. The app should include multiple classes that students can join, view lecture notes, and submit assignments.” To my surprise, Cursor generated a complete set of code files with a well-structured foundation, making it easy to customize and further develop the app to meet the project requirements.

Pricing

The Individual plan is free, but if you want to use the tool extensively with unlimited completion requests, Cursor AI offers a paid plan for $20 per month.

7. Intellicode

I’ve included Microsoft IntelliCode in this list because of its seamless integration with Visual Studio and VS Code, providing intelligent code suggestions exactly when I need them. What makes it particularly valuable is how it learns from a vast number of open-source GitHub projects, offering highly relevant code completions.

Pros of IntelliCode

• Autocompletion: Speeds up coding by offering whole-line autocompletion, analyzing the context of your code.
• Improved privacy: Since IntelliCode operates locally on your machine, it ensures the privacy of your code while providing precise, context-aware suggestions.
• Contextual IntelliSense: Suggests the most relevant code snippets by analyzing thousands of open-source GitHub projects, ensuring that the completions are tailored to your needs.
• Repeated edits detection: Identifies repeated code edits, enabling developers to apply consistent changes throughout their codebase.
• Quick actions: Recognizes common coding patterns and tasks, suggesting quick actions such as generating constructors or adding parameters to existing constructors.

Cons of IntelliCode

• Limited effectiveness with complex codebases: Suggestions may not be as effective when working with large codebases or repositories involving multiple programming languages.
• Performance issues: IDE may experience slow load times when handling large codebases and projects.

My Experience with IntelliCode

I installed IntelliCode as a VS Code extension and tested it while working with MySQL connections. When I hovered over the ‘connect’ function in the line “database = mysql.connect()”, IntelliCode displayed real-world usage examples from GitHub. By selecting a suggestion, I was able to access detailed examples from GitHub repositories and seamlessly integrate them into my code.

Overall, IntelliCode has proven to be a valuable tool in boosting my coding efficiency. It saves time by providing relevant examples directly within the IDE, eliminating the need to search for documentation or look up examples online.

Pricing

One of the best things about IntelliCode is that it’s completely free to use in Visual Studio Code. This makes it an accessible tool for developers of all levels.

8. Tabnine

I’m including Tabnine in this list because of its outstanding features that significantly enhance the coding experience. With capabilities like intelligent code completion, error detection and fixes, refactoring help, and automatic code documentation, Tabnine enables developers to write clean, efficient, and high-quality code.

My Experience with Tabnine

My experience with Tabnine has been highly positive. It assists with a variety of coding tasks, such as generating tests, fixing errors, and offering intelligent suggestions, all of which greatly improve my productivity and the quality of my code.

I started with some initial code that connected to a MySQL database. Using Tabnine’s “document code” command, I was able to enhance it. Tabnine suggested several improvements, such as creating a reusable function that encapsulates the core logic for establishing the database connection, along with adding clear documentation. These changes not only made the code more readable and maintainable but also improved its structure and reusability.

Pricing

Tabnine’s basic AI coding assistant is free to use. It includes basic AI code completions, AI-powered chat (with some limitations), and support for all major IDEs. For those who need advanced features, the pro plan is available at just $9 per user per month.

9. Sourcegraph Cody

I included Sourcegraph Cody in this list because of its seamless integration with Sourcegraph’s powerful search features. What sets it apart is its ability to understand my codebase, providing suggestions that are tailored to my repositories, documentation, and comments.
