OpenCode

OpenCode is the open-source AI coding agent built by Anomaly Innovations, Inc and used by over 16 million developers monthly. With 203k GitHub stars, 900+ contributors, and 14,000+ commits, it is one of the most actively developed AI coding tools available. OpenCode runs in the terminal, as a desktop application (macOS, Windows, Linux, currently in beta), and as an IDE extension. Its defining architecture is model and account flexibility. Developers can connect any of 75+ LLM providers via Models.dev including local models, or use BYOK with API keys from Claude, OpenAI, Gemini, or any OpenAI-compatible endpoint. They can also log in with an existing GitHub Copilot or ChatGPT Plus/Pro account to reuse those subscription quotas without paying for separate API access. The core agent capabilities include LSP-enabled context that automatically loads the right language servers so the LLM understands the codebase's types and imports, plus multi-session parallel execution that runs multiple OpenCode agents simultaneously on the same project. OpenCode ships permissive by default: the Build agent runs file edits and shell commands without per-step approval, while the restricted Plan agent asks before every edit and command, and an --auto flag clears the two remaining guards on external directories and repeated calls. Additional features include share links for session debugging, plan mode for read-only analysis, and undo/redo for iterating on AI-generated edits. OpenCode fully supports the Model Context Protocol as a client for connecting external tools: both local and remote MCP servers are supported, including OAuth authentication for remote servers such as Sentry and Context7. The agent itself is free and MIT licensed, and three optional paid products sit alongside it. OpenCode Go is a subscription at $5 for the first month and $10 per month thereafter, giving access to a curated set of open coding models, with usage capped at $12 per five hours, $30 per week and $60 per month, and one subscriber per workspace. OpenCode Zen is a curated model marketplace billed as a prepaid pay-as-you-go balance starting at $20 plus a $1.23 card processing fee, usable with any agent and cancellable at any time. OpenCode Enterprise adds centralized configuration, SSO and internal AI gateway integration, and is sold per seat on a custom quote rather than a published rate. None of the three is required: the agent runs fully featured on BYOK or a Copilot or ChatGPT login at no cost. Anomaly Innovations, Inc holds a SOC 2 Type 2 report, published through its Comp AI Trust Center at trust.opencode.ai alongside 25 policies and a subprocessor list, with documents available under NDA. It publishes no ISO 27001, HIPAA, FedRAMP or PCI certification, and states no GDPR or CCPA position on any public surface, though a Data Processing Agreement exists in the Trust Center behind an NDA request. OpenCode explicitly does not store code or context data, with all processing happening locally or through direct API calls to the developer's own provider. OpenCode is not the right fit for developers who want a managed subscription with built-in usage quotas and no configuration. Cursor ($16/mo billed annually) and Claude Code ($17/mo billed annually) provide self-contained experiences with billing, support, and model access handled by a single vendor. OpenCode requires the developer to manage their own API keys or subscription accounts, which adds initial setup friction and ongoing billing complexity when usage spans multiple model providers. OpenCode runs inside CI itself: mentioning /opencode or /oc in a GitHub issue or pull request executes the task on your GitHub Actions runner, and GitLab is supported through CI/CD pipelines or GitLab Duo. Teams that want that workflow packaged with seat management, admin controls and vendor support rather than configured per repository should evaluate GitHub Copilot ($10/mo). Current state Q3 2026: OpenCode reached 203k GitHub stars with active daily commits. The desktop app remains in beta on macOS, Windows and Linux. OpenCode Go launched as a low-cost model subscription aimed at international users, and OpenCode Data publishes a public leaderboard of model usage and cost drawn from Go traffic. The platform supports 75+ LLM providers and both local and remote MCP servers with full OAuth support.
