OpenCode is a model-agnostic, open-source AI coding agent that runs in the terminal, desktop, and IDE. It enables developers to swap between 75+ LLM providers to maintain control over costs, privacy, and performance.

Recent updates as of August 2026 include improved Azure CLI authentication, compatibility fixes for Amazon Bedrock, refined session compaction logic, and expanded locale support in the desktop application.

As of

  • Support for 75+ LLM providers including local models via Ollama
  • Dual-mode architecture with Build and Plan postures
  • Client-server design for consistent use in terminal, desktop, and CI
  • Built-in subagents like @general for complex research and tasks
  • Privacy-first design with no code or context data stored on Anomaly servers
✓ Best For

Developers who require model flexibility, cost optimization through multi-model tiers, privacy-conscious environments, or self-hosted and open-source workflows.

✗ Not Ideal For

Users seeking a zero-config managed product, teams requiring single-vendor support contracts, or those strictly restricted from using terminal-based development tools.

Free

The OpenCode agent is free and open-source (MIT License). Users pay only for model usage, either by connecting their own API keys (BYOK), using the pay-per-use OpenCode Zen gateway, or via the OpenCode Go subscription ($5 first month, then $10/month).

OpenCode is the leading open-source harness for developers who want to avoid vendor lock-in. While it requires more setup than closed-source alternatives like Claude Code, its transparency, model freedom, and lack of subscription overhead make it a powerful, durable tool for professional engineering systems.
