Before we dive in - take a moment to watch how we used Fine's AI Agent to make changes in our codebase - live, unedited.

Introduction to Replit

Replit is a browser-based integrated development environment (IDE) which recently released AI-powered features, offering autocomplete, debugging, and documentation generation. Designed to make coding accessible to beginners and professionals alike, Replit provides real-time collaboration capabilities, making it a go-to for team projects or educational purposes. It allows developers to quickly write code, generate tests, and set up APIs without complex configurations. With its broad support for multiple programming languages, Replit is a flexible choice for diverse coding tasks.

Introduction to Cursor

Cursor is an AI-powered code editor that was built as a fork of the popular IDE, VSCode. It offers advanced code completion, intelligent code refactoring, and natural language editing. Cursor also emphasizes security, with SOC 2 certification, making it suitable for teams that need stringent data privacy. While Cursor can be used as a standalone editor, it is especially valuable for developers already working in an environment like VSCode, allowing them to integrate AI assistance without disrupting their workflow.

Similarities Between Replit, Cursor, and Fine

Replit, Cursor, and Fine all focus on helping developers streamline their workflow through AI. Here are some key similarities:

  • AI-Assisted Code Generation: All three platforms use AI to generate code based on natural language prompts, significantly reducing the time developers spend writing basic code snippets. Fine goes a step further by taking an issue from Linear, GitHub, or Jira and turning it into a PR.

  • Autocomplete and Debugging: Replit, Cursor, and Fine all offer intelligent code completion and error detection, speeding up the development process and helping developers catch mistakes early. Fine also runs and tests the code it generates, fixing errors automatically.

  • Collaboration Features: While Replit offers real-time collaboration directly in the browser, Cursor is a fork of VSCode.

Differences Between Replit, Cursor, and Fine

  • Platform Integration: Replit is a full-fledged online IDE, which means users can start coding directly in the browser without setting up a local environment. Cursor, on the other hand, is more suitable for those who already have a preferred development setup in VSCode and want to remain in that familiar environment. Fine, however, works seamlessly across platforms and integrates directly with tools like GitHub, Linear, and Slack, allowing developers to work wherever they are most comfortable.

  • Collaboration and Ease of Use: Replit’s in-browser environment offers built-in real-time collaboration features, which makes it more accessible for teams or classrooms. Cursor, while collaborative, requires additional configuration for extensions and may be better suited for developers familiar with advanced setups. Fine is designed for teams; you can start a task, another colleague can complete it; you can share previews and console logs; and more.

Fine's Unique Features

Fine stands out with its unique features designed to enhance the developer experience:

  • AI Agents Fix Their Own Code: Fine runs the code after generating it, identifies errors in the console logs, and offers to fix them automatically.
  • Unlimited Premium LLM Usage: Fine provides unlimited access to leading LLMs like OpenAI's o1 and Claude 3.5 Sonnet, without requiring users to manage their own API keys.
  • Multi-Tasking Capabilities: Fine allows developers to delegate multiple tasks simultaneously, working in the cloud so you can review results at your convenience.
  • Workflow Automation: Fine automates repetitive tasks, saving developers time and effort. One of the most frustrating parts of coding with AI is reviewing the code generated by the LLM, which in some tools is littered with bugs and hallucinations.

Fine outperforms Replit, Cursor and other tools with its unique features for the best developer experience:

  • Fine runs the code after generating it and identifies errors in the console logs, offering to fix them itself.
  • Fine commits regularly and allows easy rollbacks to any stage of the conversation
  • Fine creates a new branch for each task, keeping your code safe - and it writes great commit messages
  • Fine offers a clear Line Change Summary and highlights diffs with each commit, so you can keep track of all AI changes

Comparing Cursor, Replit and Fine for AI Coding

Why Choose Cursor Over Replit

  • Security: For developers or teams that require stringent security measures, Cursor’s SOC 1 certification makes it the more reliable choice. Replit holds SOC 2 certification for enterprise customers across most of their platform, but it's not clear if that includes the new AI suite.

  • Integration with Existing Tools: If you are already using VSCode or another local development environment, Cursor’s seamless integration allows you to bring AI assistance to your current workflow without changing your setup, much. Fine doesn't require switching your IDE at all - collaborate with Fine wherever you usually collaborate with teammates.

  • Code Refactoring: Cursor excels in assisting with code refactoring and improving legacy codebases, offering smart suggestions that help maintain code quality over time.

Why Choose Replit Over Cursor

  • Fully Integrated IDE: For developers who want an all-in-one solution without the need to install additional software or manage extensions, Replit’s browser-based environment is an excellent choice. It allows you to start coding from anywhere, without the hassle of setup.

  • Beginner-Friendly: Replit’s intuitive interface and extensive documentation make it a great option for beginners or educators. Its easy-to-use collaboration tools also make it ideal for group projects or learning environments.

  • Real-Time Collaboration: Replit shines in team settings, offering a streamlined, real-time collaboration feature that works seamlessly across browsers. This is especially useful for projects where multiple developers need to work together in real-time.

Connecting Replit and Cursor

According to Twitter users, it's now easy to integrate Replit and Cursor and take advantage of how easy it is to deploy using Replit. The installation is a bit complex but explained here in detail.. You'll need to Generate an SSH Key for Replit in Cursor and add the Public Key to Replit. Then, you copy the Shell ocmmand and past it as a new SSH host in Cursor.

Why Fine is a Better Choice

While both Replit and Cursor offer compelling features, Fine takes AI-assisted coding a step further by providing advanced automation and a more comprehensive set of tools tailored for development teams. Here’s why Fine is a better alternative:

  • Unlimited Premium LLM Use Fine doesn't limit how much paid subscribers can access OpenAI's o1 or Claude 3.5 Sonnet, the leading LLMs for software development. Many other platforms require the user to provide their own API keys for OpenAI and / or Anthropic and therefore pay by usage on top of the monthly subscription.

  • Perform multiple tasks at the same time Fine works in the cloud, so you can delegate tasks and come back to them later - you don't even need to leave the browser tab open! If you're looking to delegate a number of tasks from your backlog, and come back to review them when you're ready, Fine is the obvious choice.

  • Superior Workflow Automation: Fine’s AI not only assists with code generation and debugging but also automates entire workflows, reducing the time developers spend on repetitive tasks.

  • Pull Request (PR) Summarization: Fine can summarize pull requests and help developers focus on high-level decisions by reviewing code that has already been tested and validated, a feature not available in either Replit or Cursor.

  • Customizable for Teams: Fine is designed to scale with teams, offering powerful tools for collaborative development that integrate seamlessly with existing processes. Its AI can assist in reviewing and improving code, enabling teams to work faster and more efficiently.

  • Full Context Awareness: Fine integrates with GitHub, Linear, Sentry and more, enabling the user to activate the AI wherever they're working and use information on external platforms as context.

In conclusion, Replit, Cursor, and Fine each offer solid AI-powered coding solutions with unique strengths.
