Antigravity vs Windsurf

A head-to-head look at Antigravity and Windsurf — two popular AI coding agents — and how BuySkills fits into each workflow.

Standalone IDE

Antigravity

Antigravity is an agent-based development environment focused on autonomous multi-step coding workflows. It pairs tightly with modern frontier models for planning and execution.

Standalone IDE

Windsurf

Windsurf (formerly Codeium) is a VS Code-based editor built around Cascade, an agent that can reason over your whole codebase and execute multi-step workflows. It targets teams that want agentic pair programming out of the box.

Use both with a single skill catalog

You don't have to pick. BuySkills lets you install a skill once and use it across Antigravity, Windsurf, and every other supported AI coding agent — without repurchasing or reconfiguring.

  • One command to install in either agent: npx buyskills install <skill>
  • Skills pinned to a version you choose — Antigravity or Windsurf updates won't break your loop
  • Explore plugins by category: testing, refactoring, documentation, git workflows, and more

Antigravity vs Windsurf — FAQ

Should I pick Antigravity or Windsurf?

It depends on where you work. Antigravity is agent-based development environment, while Windsurf is codeium's agentic ide with cascade. Many developers use both and share skills across them via BuySkills — so the choice is less binary than it used to be.

Can I use the same plugins in Antigravity and Windsurf?

Yes. BuySkills is designed for cross-agent portability. Install a skill once with the BuySkills CLI and it becomes available in both Antigravity and Windsurf — and every other supported agent — without a second purchase or install.

How is installing BuySkills skills different between Antigravity and Windsurf?

It isn't, from your side. You run `npx buyskills install <skill>`, and the CLI writes the skill to the directory each agent reads from. Antigravity and Windsurf pick up the skill without any extra config.

How do I add skills to Antigravity?

Install BuySkills CLI and run `npx buyskills install <skill>`. The CLI detects Antigravity and writes skills into the directory its agent reads at startup. Restart the agent loop (not the whole app) to pick up new skills.

Do skills work with Windsurf's Cascade agent?

Yes. BuySkills installs skills into Windsurf's shared skill directory, and Cascade picks them up without restart. Skills are available the moment Cascade decides to use them in a workflow.

Still deciding?

Install BuySkills CLI once and the skills you discover today work in whichever agent you pick tomorrow.
