On 2026-10-02 the Antigravity CLI author said agy 1.2.15 runs the full agent in Android Termux. The GitHub release adds prebuilt native Android binaries and drops the proot-distro requirement. Install docs still list only desktop OSes, and there is no public on-phone benchmark.

Key Takeaways

  • ✓Release: Antigravity CLI 1.2.15 (ae27bff) ships prebuilt native Android binaries that run in Termux without proot-distro
  • ✓This is the full local agent on the phone, not Remote Control of a desktop session; same harness as Antigravity 2.0
  • ✓Denied permissions (including from subagents) are respected; a too-low AI credits balance fails immediately instead of ~2.5 minutes of retries
  • ✓Install: official install.sh inside Termux, then agy; AGY_CLI_HIDE_LOGO (since 1.1.19) helps narrow screens
  • ✓Caveat: install docs still list only macOS/Linux/Windows; no public Termux latency or coding score. Older community patches are not 1.2.15 results

In-Depth Technical Analysis

Why this shipped

Antigravity CLI (agy) is the TUI for the same agent harness as Antigravity 2.0: multi-step reasoning, multi-file edits, tools, and conversation history. It is aimed at SSH and headless shells, not a desktop IDE. Phones previously meant Remote Control of a session that still lived on another machine. Running the official binary locally on Android meant proot-distro or community patches (glibc shims, 39-bit VA). The install doc still lists only macOS, Linux, and Windows.

What 1.2.15 actually changes

GitHub release 1.2.15 (ae27bff, published by haofan on 2026-10-02, page time about 17:00 with no timezone) adds prebuilt native Android binaries that run directly in Termux without proot-distro. The same release makes the agent honor a denied permission—including one a subagent cannot ask you to approve—instead of working around it, and it cuts memory allocated on each typing, scroll, and streaming redraw. Narrow-terminal wrapping (~40 columns) landed in 1.2.13; AGY_CLI_HIDE_LOGO has existed since 1.1.19. Author Shengzhe (profile: Antigravity at Google DeepMind) said 1.2.15 is the full agent in the phone terminal.

Benchmarks

None published for Termux or Android: no latency, throughput, or coding score. The changelog only says a depleted AI-credits balance now fails immediately with “Your AI credits balance is too low to continue.” instead of retrying for about two and a half minutes. Older community posts (for example CLI 1.0.1 patches) are not results for this official binary. About 42k views and 750 likes on the announcement measure attention, not speed.

Try it

Inside Termux, run the same official installer the author posted (https://antigravity.google/cli/install.sh), then agy. Auth is unchanged: browser sign-in, paste-the-code when no browser can open, or modelProvider: gemini plus GEMINI_API_KEY in ~/.gemini/antigravity-cli/settings.json. Set AGY_CLI_HIDE_LOGO on a narrow screen. Treat docs as not yet updated for Android, and do not expect official numbers for storage, keyboard, or background lifetime. This path runs the agent on the phone; it is not Remote Control of a desktop CLI.
