opencode

OpenCode competes on two axes most coding agents avoid: model neutrality and the surfaces you already use. The homepage is explicit that you get "free models included or connect any model from any provider, including Claude, GPT, Gemini and more," and the docs route everything through Models.dev — which the vendor says covers 75+ LLM providers, local models among them. That matters if you have opinions about which model writes your code and refuse to have them shipped to you in a bundle. The more interesting argument is subscription reuse. You can log in with GitHub to spend a Copilot account, or with OpenAI to spend a ChatGPT Plus or Pro account. If you already pay for either, you are not buying a second seat — you are pointing an agent at a subscription you already own. The Free plan features list both paths alongside free included models. The engineering story is more serious than a prompt wrapper. OpenCode automatically loads the right LSPs for the LLM, so it reasons over real language-server type information instead of guessing from raw text. Multi-session runs several agents on the same project at once, and share links let you hand a teammate a URL to any session. The changelog backs this up with the sort of fixes only a used product ships: Bedrock reasoning responses no longer cache into unreplayable empty messages, Azure providers sign in with Microsoft Entra ID through the Azure CLI, Cloudflare AI Gateway routing was corrected for third-party providers and for Anthropic's dotted model IDs, and session compaction preserves complete recent turns. Subsequent releases added the Astra system prompt for GPT-6 models and limited Anthropic thinking block binding to Claude 5.1+. The privacy stance is blunt and specific: the vendor states OpenCode does not store your code or context data, which is what makes it arguable in environments where shipping source to a third party is off the table. On abandonment risk the project answers with numbers rather than vibes — 208,000+ GitHub stars, 950 contributors, 13,000+ commits, 16M monthly developers. Where it does not fit: the terminal interface has a learning curve, the desktop app is in beta, and managing multiple provider keys is real work. There is no advertised first-month discount any more — the changelog records that OpenCode Go first-month discount messaging and pricing were removed in v1.18.22. If you want polished opinionated defaults and a managed product, Cursor or GitHub Copilot will get you there faster. If you want the agent to be yours, this is the one to beat.
