OpenCode is a fully open-source AI coding agent built by Anomaly that runs in the terminal, desktop, and IDE — and connects to more than 75 LLM providers including Claude, GPT, Gemini, and local models. It currently has over 140,000 GitHub stars and 850 contributors, making it one of the fastest-growing open-source developer tools of 2026. Unlike vendor-locked coding agents, OpenCode lets developers bring their own subscriptions (ChatGPT Plus, GitHub Copilot) or connect local models through LM Studio. It supports the Agent Client Protocol (ACP) for broad IDE compatibility — JetBrains, Zed, Neovim, Emacs, VS Code, and Cursor — and emphasizes a privacy-first architecture that never stores your code or context data. The optional Zen tier provides a curated, benchmarked set of AI models specifically optimized for coding workflows, offering a premium experience without locking users into a single cloud provider. With an Early Bird period ending April 14, OpenCode is rapidly becoming the go-to open alternative to Claude Code and Copilot for developers who want control over their stack.

The free tier is incredibly generous. Multimodal capabilities and grounding with Google Search are unique advantages.

140K stars isn't hype — OpenCode has real momentum because it solves the actual problem: vendor lock-in. I can use my existing Claude subscription, switch to a local Gemma model when I need privacy, and have it work in every IDE I already use. This is what the coding agent space needed.

Skeptic

Google's track record of killing products is concerning, but the Gemini API is too useful to ignore.

45/100 · skip

The 'works with 75 models' pitch sounds great until you realize most of those models are dramatically worse at coding than Claude or GPT-5. The premium Zen tier is where the real value likely lives, and we don't know what that costs yet. Wait to see how Zen pricing shakes out before committing.

Google's data advantage and multimodal-first approach make Gemini a serious contender in the model race.

OpenCode is the Mozilla Firefox moment for AI coding tools — an open-source reference implementation that keeps the big players honest on privacy and portability. The Agent Client Protocol integration points toward a future where your coding agent context travels across every tool in your workflow seamlessly.

The multi-session and shareable session link features are underrated for creative teams. Being able to share an in-progress coding session with a designer or content collaborator without spinning up another subscription is genuinely useful. Privacy-first matters a lot when working with client IP.
