AMP vs Antigravity
A head-to-head look at AMP and Antigravity — 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.
Antigravity plugins on BuySkillsSide-by-side
| Dimension | AMP | Antigravity |
|---|---|---|
| Surface | Agent framework | Standalone IDE |
| In a nutshell | Sourcegraph's agentic coding tool | Agent-based development environment |
| BuySkills install command | npx buyskills install <skill> | npx buyskills install <skill> |
| Cross-agent skill sharing | Yes — via BuySkills | Yes — via BuySkills |
Use both with a single skill catalog
You don't have to pick. BuySkills lets you install a skill once and use it across AMP, Antigravity, 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 — AMP or Antigravity updates won't break your loop
- Explore plugins by category: testing, refactoring, documentation, git workflows, and more
AMP vs Antigravity — FAQ
Should I pick AMP or Antigravity?
It depends on where you work. AMP is sourcegraph's agentic coding tool, while Antigravity is agent-based development environment. 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 AMP and Antigravity?
Yes. BuySkills is designed for cross-agent portability. Install a skill once with the BuySkills CLI and it becomes available in both AMP and Antigravity — and every other supported agent — without a second purchase or install.
How is installing BuySkills skills different between AMP and Antigravity?
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. AMP and Antigravity pick up the skill without any extra config.
Does AMP's agent run BuySkills skills on indexed codebases?
Yes. AMP calls BuySkills skills as part of its agent plan, and the skills have access to the same indexed codebase context that AMP's native tools do. That makes refactor and analysis skills especially powerful in AMP.
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.
Still deciding?
Install BuySkills CLI once and the skills you discover today work in whichever agent you pick tomorrow.
