The free alternative to Antigravity CLI
Agentic coding in your terminal — without Google’s editor fork.

James GrugettCo-founder, Freebuff
TL;DR
- Antigravity is Google’s agentic IDE — polished, Gemini-powered, fork of an editor.
- Freebuff is editor-agnostic — runs in your terminal inside VS Code, JetBrains, Vim, or Cursor.
- Both are free at launch; only Freebuff is structurally free long-term (ad-supported, not VC-subsidized).
- Antigravity is Gemini-only. Freebuff lets you switch models per task.
Antigravity is what happens when Google ships its answer to Cursor — an opinionated agentic IDE with Gemini deeply integrated. Freebuff is the same agent power in your existing terminal, without changing editors or vendors.
What Antigravity costs in 2026#
Antigravity is free at launch. Long-term pricing is not finalized — expect Gemini API usage or seat fees similar to other Google dev tools. Budget ~$20/mo equivalent when comparing total cost of ownership.

When Antigravity wins#
- You’re happy switching editors and love a tightly-integrated UX.
- You’re all-in on Gemini for its long-context and multimodal strengths.
- Cloud-first workflows where the agent running in Google’s cloud is a feature, not a tradeoff.
When Freebuff wins#
- You don’t want to migrate editors — Freebuff goes wherever your terminal goes.
- You want vendor-agnostic model choice.
- You want a guaranteed-free tier, not a free preview that may change.
- Local-first matters — your code doesn’t leave your machine.

Install FreebuffWill Antigravity stay free?+
No commitment yet. Like most launches, Antigravity’s pricing will likely evolve. Freebuff’s free tier is a permanent commitment funded by CLI ads.
Does Freebuff have a "cascade"-style multi-file agent loop like Antigravity?+
Yes. Freebuff plans across files first, then applies edits in a single pass that you can review and approve, with the code-reviewer subagent verifying afterwards.
