OpenCode 2.2.5 for Termux

OpenCode v2 as a native Android/aarch64 Bionic binary for Termux: no PRoot, no glibc. This release moves the Android build from 2.0.28 to 2.2.5, and fixes the reason the previous 2.2.x candidates died before drawing a single frame.

Install

curl -fsSL https://github.com/Spectra010s/opencode-termux/raw/v2.2.5/install.sh | sh

Then run opencode. The installer checks the compressed download and the executable against the release checksums before replacing ~/.local/bin/opencode, and keeps your chats, sign-ins, and configuration.

Already on 2.0.28? Run opencode upgrade. It points at this verified installer.

Requires Android 9 (API 28) or newer, aarch64, and about 700 MiB free.

What changed upstream (2.2.0 → 2.2.5)

  • /goal: keep a session working toward an objective until a reviewer confirms it is met (/goal pause, /goal resume, /goal clear).
  • Image generation: agents can create or edit images through experimental_image_generate, enabled automatically when a connected provider has image models.
  • Claude Agent: sign in with Claude Code (claude auth login) and select it in /connect to use those models.
  • OpenTUI 0.8: TUI plugins now require @opentui/core and @opentui/solid 0.8 or newer; scroll and render-context APIs changed accordingly.
  • Compaction buffer as a percentage: "compaction": { "buffer": "20%" } keeps part of any model's context window free.
  • Fixes: MCP servers sending messages over 10 MiB no longer get disconnected, calls to a tool named bash run as shell instead of failing, and read/edit errors now point at the missing folder or the closest matching lines.

Desktop-only changes in these versions (persistent desktop terminals, artifacts, the desktop model picker) do not apply to this Termux build.

What changed in this Android build

  • Built from pinned OpenCode source with Bun 1.4.4 and OpenTUI 0.8.0 (Zig 0.16.0); versions, hashes, and commits live in tools/supply-chain-lock.json.
  • The candidate now compiles directly against the pinned Android Bun base and grafts the bionic OpenTUI library onto it. Re-running the old post-compile transplant on a 1.4.4 base produced a binary that died with SIGILL on the first instruction.
  • TUI fix: Android bionic tags heap pointers in the top byte, and OpenTUI's FFI shim rejected those as unsafe (Pointer exceeds safe integer range) before the first frame. The build now masks that tag before the check, so the renderer starts normally.
  • opencode upgrade still points at this verified installer instead of an incompatible upstream download. opencode uninstall --dry-run previews removal; opencode uninstall removes the binary and shared cache but keeps user data.

Verified build

The candidate came from Actions run 41906034445, built and checked by CI, with sha256 24e9600d80752a31c052135a75677495fcb0ee694580216aa9dc37a89a75d657. It was tested: --version passed, providers and models listed through the server, and the TUI started. Wider device testing is welcome; report problems at issues.

Checksums and build inputs are attached to this release. The source-build guide shows how to reproduce the build.
