Claude Code vs OpenCode on Phone: 2026 Honest Pick

Short answer. Use Claude Code when you want Anthropic-tuned surface area (Plan mode, Agent Skills, Agent Teams, Remote Control), paid for through a Claude.ai subscription you already have. Use OpenCode when you want one MIT-licensed binary that brokers Anthropic, OpenAI, Google, and local models, with a TUI by default and a serve/run mode that exposes an HTTP API. Both are CLIs that need a real Linux or macOS shell, so the phone question is the same one: where does the CLI actually run? We pre-install both, plus Codex CLI and Gemini CLI, inside one Ubuntu 24.04 container on Cosyra for iOS or Cosyra for Android, so you can switch by typing claude or opencode in the same directory.

This guide was written by the Cosyra team. We use Claude Code and OpenCode daily from a phone, on iOS and Android, against Cosyra's Ubuntu container. Where we make claims about either tool we cross-checked them against the official repos at github.com/anthropics/claude-code and github.com/anomalyco/opencode, the OpenCode docs at opencode.ai/docs/cli, and the public source links in each FAQ answer. Source verification date 2026-05-28.

We wrote this from a coffee shop on a Wednesday afternoon, the same test rig we use for every Cosyra comparison: iPhone 15 Pro and a Pixel 8 over LTE, no laptop, two terminal sessions, one project. Same prompt to both: "audit this Python module for dead code and write a removal plan." Claude Code opened in Plan mode, drafted a four-step approach before touching a file, asked us to approve the plan, then executed the diff cleanly. OpenCode used its 'plan' agent for the read-only pass, then we switched to its 'build' agent for the edits, picked Sonnet via --model anthropic/claude-sonnet-4-5 on a hunch the same model would land closer to the same diff, and it largely did. Same hardware, same network, two different shapes of the same job.

What are Claude Code and OpenCode, exactly?

Both are terminal AI coding agents that read your project, propose changes, run commands, and write to disk. They live in a process you start by typing claude or opencode inside a project directory. Both fetch model completions over the network. The differences live in license shape, model-provider strategy, agent surface area, and what is included out of the box.

Claude Code (Anthropic)

Claude Code is Anthropic's official terminal agent for Claude. It installs via npm install -g @anthropic-ai/claude-code and authenticates against a Claude.ai Pro, Max, Team, or Enterprise subscription, or against an ANTHROPIC_API_KEY. Source is published at github.com/anthropics/claude-code under a custom license that is not Apache or MIT. Notable surface-area features: Plan mode (drafts an approach before touching files), per-tool permissions, hooks, Agent Skills, Agent Teams (coordinated subagents with a shared task list), and the Remote Control feature added 2026-02-25 that drives a laptop session from the Claude iOS/Android app.

OpenCode (Anomaly / @thdxr)

OpenCode is an MIT-licensed open-source agent published by Anomaly (org anomalyco on GitHub; lead maintainer @thdxr — the same person who built it under the SST org before the rename, GitHub still redirects the old sst/opencode path). It installs via npm i -g opencode-ai@latest, curl -fsSL https://opencode.ai/install | bash, brew install anomalyco/tap/opencode, scoop install opencode, choco install opencode, sudo pacman -S opencode, paru -S opencode-bin, mise use -g opencode, or nix run nixpkgs#opencode. That is nine real distribution paths, more than any other agent in the category. The code is mostly TypeScript with a small Rust component. The binary is provider-agnostic and brokers Anthropic, OpenAI, Google, and local models via the /connect command and the auth flow at opencode.ai/auth. As of 2026-05-31 OpenCode is at v1.15.13 with 167,544 GitHub stars; it crossed 1.0 between April and May 2026 and currently ships multiple releases per day.

How do they compare feature by feature?

Twelve dimensions that matter on a phone. We left out things like overall "code quality" that can only be answered by running both on your own repo, and we cite the source in line where the claim isn't already in either project's README.

The two rows developers ask about most are "Model providers" and "License." They sit at right-angles to each other: OpenCode wins on flexibility and license shape, Claude Code wins on Anthropic-specific tooling depth. The feature surface around Plan mode and headless modes overlaps more than the marketing on either side suggests.

What changes when you actually run them from a phone?

The differences that look minor on a 15-inch laptop become first-order on a 6-inch phone with a software keyboard. Three things stand out.

1. Per-step approval prompts vs workspace defaults

Claude Code's default approval flow asks before most shell commands; that is a thumb tap per tool call. OpenCode's 'build' agent runs through tool calls with the workspace-friendly default; switch to the 'plan' agent when you want strictly read-only behavior. On a phone keyboard those defaults stack up: a hundred-step refactor under Claude Code is a hundred extra interactions. The counter-point is the same one that comes up with every agent: when the agent is about to do something destructive, the prompt is what saves you. Anthropic has an open feature request, anthropics/claude-code#31604, asking for a simple Full Access toggle that mirrors looser defaults; until it lands, the phone-keyboard asymmetry is real and OpenCode's 'build' agent feels lighter to drive from a phone.

2. Provider switching on the same prompt

On a phone you start more sessions and end more sessions. You also probe more — "is this an Anthropic-shaped task or a Gemini-shaped task?" — because you do not have IDE muscle memory to lean on. OpenCode's --model anthropic/claude-sonnet-4-5 versus --model openai/gpt-5 versus --model google/gemini-2.5-pro on the same prompt is a one-line change. Claude Code's answer is "open a second tool"; that is what Cosyra helps with (both agents share the directory) but it still costs a context switch. For exploratory phone usage OpenCode's single-binary flexibility is a genuine ergonomic win.

3. Scripting and "agent as a service"

On a laptop nobody scripts the agent from the agent. On a phone you sometimes do — long-running background work that you check on, where the agent is more of a service than a chat partner. OpenCode's opencode serve exposes an HTTP API and opencode run --format json is the scriptable entrypoint; the README even calls out running the server "on your computer while you drive it remotely." That maps cleanly onto a phone-driven workflow against a cloud container. Claude Code's surface is more agent-as-chat; it covers more ground inside one session but does less at the orchestrator boundary.

When does Claude Code win?

Pick Claude Code when Anthropic-tuned surface area matters more than license shape or multi-provider freedom:

• You already pay for Claude.ai Pro/Max. Authentication is one sign-in, billing is one line item, Remote Control is included with the plan.
• Architecture and design work. Plan mode is the cleanest pre-flight flow in the category. Agent Skills package complex workflows into one-call capabilities the OpenCode binary does not match out of the box.
• Agent Teams. Coordinated subagents with a shared task list is genuinely useful on long refactors; we have not seen a clean OpenCode equivalent.
• Mobile remote control of a laptop session. If you have a Mac mini at home running Claude Code, Remote Control from the Claude iOS app is a real workflow that OpenCode does not have a first-party answer for.
• You want one vendor. Anthropic ships the model, the agent, and the iOS/Android client. One support channel, one billing path.

When does OpenCode win?

Pick OpenCode when license, multi-provider flexibility, or scripting ergonomics matter more than Anthropic-specific surface depth:

• MIT requirement. If your team or customer needs a permissive open-source license — fork it, audit the source, run it air-gapped against a local model — OpenCode fits cleanly. Claude Code's custom license is a non-starter.
• Multi-provider in one binary. Switch between Anthropic, OpenAI, Google, and local on a flag. No second install, no second config, no second auth flow.
• Headless server mode. opencode serve plus the HTTP API is genuinely useful for IDE plugins, CI runners, and scripted phone workflows. Claude Code does not match it.
• Provider-agnostic price floor. If you have a Google free tier already (60 rpm / 1,000 rpd on Gemini through 2026-06-17, see our Claude Code vs Gemini CLI guide), pointing OpenCode at it is the cheapest way to run agentic loops.
• Open community momentum. 167,544 stars, multiple releases per day, MIT. The velocity is real.

Who should pick OpenCode instead of Claude Code (and vice versa)?

Try OpenCode first if license shape is a hard constraint, you want one binary that brokers four providers, you script your agent workflows, or you want to experiment with local models. The opencode command from a Cosyra container with three provider keys in your environment is the most flexible single-tool setup on a phone today.

Try Claude Code first if you live in the Anthropic ecosystem, you ship customer-facing UI or large refactors, you want Plan mode and Agent Skills out of the box, or you already pay for Claude.ai Pro/Max. Pair it with Cosyra for the moments your laptop is not around, and use Remote Control for the moments it is.

The most productive setup we see is the boring one: both, side by side, on the same container, dispatched by task. OpenCode for fast multi-provider experiments, Claude Code for the careful diff and the architecture work. They do not collide; they cover different parts of the surface.

How do you set both up on a phone today?

Three working paths in 2026. We recommend the first because it's the one we built; the other two are honest fallbacks.

1. Cosyra: Ubuntu container with both pre-installed

Install Cosyra for iOS or Cosyra for Android, sign in with Apple, Google, or email. A fresh Ubuntu 24.04 x86_64 container provisions on first launch with Claude Code, Codex CLI, OpenCode, and Gemini CLI on PATH. Add your keys (ANTHROPIC_API_KEY for Claude Code; /connect inside OpenCode for whichever providers you want), clone a repo, and type claude or opencode. Hibernation pauses the container after 10 minutes idle and resumes in place; 30 GB persistent storage; same container reachable from iPhone, Android, and the web.

2. Termux on Android with workarounds

Install Termux from F-Droid or the Play Store (Android 11+), install Node 20+ with pkg install nodejs, then npm install -g @anthropic-ai/claude-code for Claude Code. OpenCode on Termux is shakier: the launcher still misdetects Termux as plain Linux per open issue #21043 and the fix PR #21106 was closed without merging. The native-Termux feature request #22805 was closed without a maintainer commitment. The working workaround is to run OpenCode inside proot-distro with a Debian or Ubuntu chroot; it works but it is not a great phone experience. Android 12+'s phantom-process killer can also terminate long agent sessions for either CLI. There is no iOS equivalent of Termux. See our OpenCode on your phone and Claude Code on Android guides for current workaround sets.

3. SSH from Blink Shell on iOS into a VPS

On iPhone or iPad, Blink Shell ($19.99/year) is the cleanest SSH client. Rent a VPS (Hetzner, DigitalOcean, Scaleway), install Node 20+, then install either CLI via npm. Sign in via API key — the browser flows for both Claude.ai sign-in and OpenCode's /connect auth are awkward over SSH. The cost is the sysadmin time on the box. See SSH from phone for the end-to-end stack.

What this actually looks like on a phone

An afternoon we had this week: coffee shop, no laptop. Opened Cosyra on the Pixel 8 over LTE. Typed opencode, ran the same audit prompt against Sonnet and against GPT-5 with one flag flip, eyeballed both diffs for the same problem. Then typed claude in the same directory, let Plan mode draft a four-step refactor of the spot both models flagged, approved the plan, and watched Claude land a careful diff that touched three files and added a missing test. OpenCode was the comparison harness; Claude Code was the careful change; Cosyra was the shell. That is the workflow the two tools and a phone screen converge to once you stop pretending the phone has to be a laptop. Different agents for different parts of the job, one container, two thumbs.
