OpenCode alternatives: 8 terminal coding agents compared

The main OpenCode alternatives in 2026 are Claude Code (best if you pay for Claude), OpenAI Codex CLI (best with a ChatGPT plan), Kilo CLI (an OpenCode fork with a model gateway), Crush (Charm's terminal agent), Aider (git-native pair programming), Gemini CLI (a large free tier) and Darce (250+ models on one plan, with undo for shell commands).

Last checked: October 2026. Facts about each tool come from its official docs or repository; versions and star counts are as of October 10, 2026.

Is there a reason to leave OpenCode at all?

Often, no. OpenCode is MIT licensed, has more GitHub stars than any other tool on this page (over 200,000), and its docs say it supports "75+ LLM providers" plus local models through Ollama, LM Studio and llama.cpp. You can sign in with ChatGPT Plus/Pro, GitHub Copilot or GitLab Duo, bring your own API keys, or use OpenCode's own Zen (a curated, tested model list) and Go (a low-cost subscription for open coding models). It runs as a terminal UI, a desktop app and an IDE extension, and has /undo and /redo.

What OpenCode does best: maximum provider choice, local models, and a huge community. If that is what you want, keep it.

People still look for alternatives for a few recurring reasons:

• They want to use a Claude Pro or Max subscription. OpenCode's provider docs say Anthropic prohibits using Claude Pro/Max through third-party plugins, and OpenCode stopped bundling those plugins as of version 1.3.0. To use a Claude subscription for coding, you use Claude Code.
• They don't want to manage provider keys and billing across several vendors.
• They want stronger guardrails around what commands the agent can run.
• They want a specific workflow: git-first pair programming (Aider), a free tier from Google (Gemini CLI), or the agent that ships with their ChatGPT plan (Codex CLI).

OpenCode alternatives compared

OpenCode vs Claude Code

These are the two most common choices, and the split is simple.

Claude Code is Anthropic's own agent. It runs in the terminal, VS Code, JetBrains, a desktop app and the browser, and it has the deepest feature set of anything here: MCP, hooks, skills, subagents, background agents, scheduled routines, GitHub Actions and an Agent SDK. Most surfaces need a Claude subscription or an Anthropic Console account. It is built for Claude models; Anthropic's docs say it "doesn't support routing Claude Code to non-Claude models through any gateway" (see running Claude Code with other models for what people do anyway).

OpenCode is the open, provider-neutral option. You can point it at almost any model, including local ones, and pay providers directly.

Pick Claude Code if you mostly use Claude and want the included usage of a Pro or Max plan. Pick OpenCode if you want to switch vendors, run local models, or read the source of the tool that runs on your machine. If you are weighing Claude Code against other agents more broadly, see our Claude Code alternative page.

OpenCode vs Codex

Codex CLI is OpenAI's open source (Apache-2.0) terminal agent, written in Rust. Sign in with a ChatGPT Plus, Pro, Business, Edu or Enterprise plan, or use an API key. It runs commands inside a sandbox and lets you choose what Codex may do without asking via /permissions. It can also run open models locally: the --oss flag with --local-provider set to Ollama or LM Studio.

OpenCode can also use a ChatGPT Plus/Pro login, so the question is less about model access and more about the harness. Codex is tuned by OpenAI for OpenAI's models and has OS-level sandboxing. OpenCode gives you every other provider in the same interface.

Pick Codex if you live in OpenAI's models and want the sandbox. Pick OpenCode if you want GPT one day and Claude, Qwen or a local model the next. Our Darce vs Codex CLI page compares sandboxing with risk-scored approvals in more detail.

The alternatives, one by one

Claude Code

Best for people already paying for Claude. The ecosystem (MCP servers, hooks, plugins, IDE extensions, the Agent SDK) is the largest of any coding agent. Its /rewind restores Claude's own file edits but, per Anthropic's checkpointing docs, not files changed by Bash commands. We cover that gap in Claude Code rewind vs Darce undo.

OpenAI Codex CLI

Best for ChatGPT subscribers. Open source, actively released (version 0.162 shipped on October 9, 2026), with a sandbox for commands and local model support through --oss.

Kilo CLI

Kilo's docs say plainly: "The Kilo CLI is a fork of OpenCode and supports the same configuration options." It adds Kilo's modes (Architect, Ask, Debug, Orchestrator, or custom agents) and the Kilo Gateway, which gives access to hundreds of models through one endpoint with bring-your-own-key support. The same team ships VS Code and JetBrains extensions. If you like OpenCode but want Kilo's account, gateway and IDE extensions, this is the closest swap. Install: npm install -g @kilocode/cli.

Crush

Charm's terminal agent, with a polished TUI, LSP integration for extra code context, and MCP over stdio, HTTP and SSE. It auto-discovers local models from Ollama, llama.cpp, LM Studio and others. Note the license is FSL-1.1-MIT (a source-available license that converts to MIT later), not MIT from day one. Install: brew install charmbracelet/tap/crush or npm install -g @charmland/crush.

Aider

The original git-native terminal pair programmer. It builds a map of your repository, commits each change with a sensible message, and works with almost any model, including local ones. One honest caveat: the last tagged release on GitHub is v0.86.0 from August 2025, and the repository was last updated in May 2026, so development has slowed compared with the other tools here. See Darce vs Aider.

Gemini CLI

Google's open source agent. Signing in with a personal Google account gives 60 requests per minute and 1,000 requests per day with Gemini 3 models and a 1M-token context window, which is the most generous free tier on this list. It is built around Gemini models. See Darce vs Gemini CLI.

Goose

An open source (Apache-2.0), extensible agent that works with any LLM. The repository now lives at aaif-goose/goose. A good choice if you want a general-purpose agent rather than a coding-only one.

Darce

Darce is the agent this site is about, so weigh this section accordingly. It is MIT licensed and runs in the terminal. One plan covers 250+ coding models through OpenRouter (Claude, GPT, Gemini, Qwen, DeepSeek, Kimi, GLM, Grok), so you never set up provider keys; switch with /model or Shift+↑/↓ mid-task.

Where it differs from OpenCode:

• Undo covers shell commands. /undo snapshots your working tree before every change using private git refs, so it also reverses files a code generator, formatter or rm created, changed or deleted.
• Every command is risk-scored. In the default mode, network access, installs and destructive commands ask first with the reason; scripts like npm run deploy get a second look from a classifier, and anything /undo can't reverse (deploys, migrations, releases) always asks. See Safety.
• Model races and parallel agents. /derby races three models on one task in separate worktrees; /swarm splits a task across 2 to 4 parallel agents.

Where OpenCode is better: local models (Darce doesn't run them), paying providers directly at their rates, more interfaces, and a far larger community. Darce's undo also has limits: shell-command undo needs a git repository, history lasts for the session, and gitignored files like node_modules aren't snapshotted. Full comparison: Darce vs OpenCode.

Which OpenCode alternative should you pick?

• You pay for Claude Pro or Max: Claude Code. It is the supported way to use that subscription for coding.
• You pay for ChatGPT: Codex CLI, or keep OpenCode with the ChatGPT login.
• You want something free: Gemini CLI for Google's free tier; OpenCode or Aider with local models if you have the hardware.
• You like OpenCode but want an account-based gateway and IDE extensions: Kilo CLI.
• You want a beautiful TUI and LSP context: Crush.
• You want every change committed to git as you go: Aider.
• You want many models without managing keys, and undo for shell commands: Darce. Try it with npx darce-cli (free trial, no account), then see Getting started, the model directory and pricing.
