For those seeking the best overall AI coding tool, Lovable.dev stands out due to its easy integration with Supabase, making database connections faster and more efficient. This feature simplifies backend setup and allows developers to build applications with minimal hassle. If ease of use and less errors are priorities, Lovable.dev is my recommended choice.
AI-powered coding tools have changed the way developers approach application development. These tools streamline the coding process by allowing users to describe their intended project in natural language, and the AI then generates the necessary code to bring their vision to life. Two tools that stand out in this field are Bolt.new and Lovable.dev. Both offer powerful AI-driven development assistance, but how do they compare when tasked with building an application?
To explore this, we conducted an experiment where both tools were given the same prompt. We assessed their speed, efficiency, feature set, and overall usability to determine which tool provides the best experience.
Features and Functionality
Initial Setup and Code Generation
- Bolt.new: This tool quickly installs all dependencies and sets up the project structure. It then provides a detailed list of features that were automatically generated.
- Lovable.dev: Before generating any code, this tool first presents a structured plan. It outlines design inspiration, key features for the initial version, and UI elements before proceeding with the coding process.
- Winner: Bolt.new, as it generates a working prototype more quickly. However, Lovable.dev‘s structured approach could be beneficial for those who prefer more planning upfront.
Drag-and-Drop Task Management
Both tools successfully implemented a functional drag-and-drop interface for task management. However, there were some differences:
- By default, neither tool allowed inline task editing.
- Bolt.new: Included the ability to add new columns right away, making the app more flexible from the start.
- Lovable.dev: Did not allow new columns to be added without additional modifications.
- Winner: Bolt.new for offering greater functionality at the initial stage.
Code Editing & Version Control
- Bolt.new: Provides an in-app code editor, enabling direct modifications without needing external integrations.
- Lovable.dev: Requires GitHub integration to edit generated code.
- Winner: Bolt.new, as the ability to edit code within the platform adds convenience and efficiency.
AI-Powered Feature Updates
We tested the AI’s ability to modify the application by requesting two feature enhancements:
- Enable inline task editing.
- Add a new column.
- Bolt.new: Implements its “diffs” feature, which updates only the necessary sections of code rather than regenerating entire files. This results in quicker and more efficient modifications.
- Lovable.dev: Took slightly longer but successfully implemented both changes.
- Winner: Bolt.new, thanks to its optimized approach that reduces unnecessary processing.
Design Customization
Both tools were asked to redesign the app to resemble Spotify’s aesthetic, which includes a dark mode with green accents.
- Bolt.new: Applied the changes smoothly, achieving a clean and professional UI.
- Lovable.dev: Also executed the requested changes but had minor readability issues.
- Winner: Bolt.new, due to its stronger implementation of accent colors.
Advanced Features
We then introduced additional complexity by requesting three features:
- Multiple boards
- Task due dates
- Task commenting
- Multiple Boards:
- Bolt.new: Implemented a dropdown-based board-switching system.
- Lovable.dev: Added board navigation at the top, making it easier to see all available boards.
- Winner: Lovable.dev for superior navigation design, though Bolt.new excelled in functionality.
- Due Dates:
- Bolt.new: Integrated the feature with minimal errors and clear UI presentation.
- Lovable.dev: Encountered an initial error but corrected it after troubleshooting.
- Winner: Bolt.new, for its smoother execution.
- Task Comments:
- Both tools handled this feature well, allowing users to leave comments on tasks.
- Winner: Tie
Performance and Speed
- Bolt.new: Shows a noticeable advantage in speed, especially when using the “diffs” feature, which optimizes updates.
- Lovable.dev: Performs slightly slower but still maintains a reasonable pace.
- Winner: Bolt.new for delivering faster results.

| UI Customization | ✅ Smooth implementation | ❌ Slight readability issues |
| Feature Updates | ✅ Efficient “diffs” system | ⏳ Slightly slower |
| Multiple Boards | ✅ Functional dropdown | ✅ Better navigation layout |
| Task Due Dates | ✅ Immediate implementation | ⏳ Initial errors encountered |
| Task Comments | ✅ Effective | ✅ Effective |
Choosing the Right Tool
- Use Bolt.new if you need fast, efficient, and easily editable code.
- Use Lovable.dev if you prefer a structured workflow with detailed planning.
Both tools provide valuable assistance in AI-driven coding, and the best choice depends on your priorities. If speed and direct code editing are your top concerns, Bolt.new is an excellent option. If you favor a more guided experience with a structured approach, Lovable.dev is a strong alternative.
