* Windsurf for exploring new codebases

The Future

Antigravity's Potential

If Google continues development, Antigravity could become the dominant tool due to:
* Google's AI expertise
* Integration with Google Cloud
* Massive context window

Cursor's Advantage

Cursor has first-mover advantage and the most mature feature set. They're likely to remain the leader for power users.

Windsurf's Niche

Windsurf's focus on “Flow” appeals to developers who value intuition over speed. They're carving out a loyal user base.

Conclusion

There's no single “best” tool. The right choice depends on your workflow, project size, and personal preferences.

At BYS Marketing, we use all three:
* Cursor for 80% of our work
* Antigravity for large refactoring projects
* Windsurf when onboarding to new client codebases
