Editorial verdict
#5 coding CLI — active again after a development gap. v1.2.27 released 2026-03-16 with OpenAI official partnership (post-Anthropic block). 124,766 stars make this the largest AI coding repo by raw count. The unauthenticated RCE was fixed in v1.1.10+ but the corporate blocking incident and security history require explicit disclosure. Best for developers who want maximum model flexibility with a proven star-signal community.

Public evidence
Community compared it favorably to Aider and Claude Code. Maintainers confirmed multi-frontend ambitions and feedback-loop capabilities.
Revealed OpenCode reverse-engineered Claude Code auth endpoints. Multiple commenters praised OpenCode's TUI engineering as superior to Claude Code's terminal experience.
Critical: previous versions exposed local server allowing arbitrary code execution from any website. Fixed in v1.1.10+. Important risk signal for enterprise adoption.
Covers OpenCode's 75+ model support, privacy-first architecture, and LSP integration. Describes it as competing directly with Claude Code and Copilot.
Groups OpenCode with Cline and Aider as the three OSS coding agents solving vendor lock-in. Highlights provider-agnostic architecture as key differentiator.
Development resumed with v1.2.27 (2026-03-16). OpenAI official partnership established after Anthropic blocked third-party Claude subscription use. Pivoted from Claude-proxy to OpenAI-partnered architecture. 393,191 npm downloads/week as of 2026-03-19.

Where it wins
124,766 GitHub stars — largest AI coding repo by raw star count
OpenAI official partnership (2026) — first major model vendor to officially support OpenCode
75+ model providers including local models via Ollama — broadest provider support
MIT license, privacy-first: does not store code or context
Active again: v1.2.27 released 2026-03-16
Where to be skeptical
Unauthenticated RCE fixed in v1.1.10+ — but security history requires disclosure for enterprise adoption
Corporate blocking incident: Anthropic banned third-party Claude subscription use (625 HN pts, Jan 2026)
Star surge driven by Anthropic OAuth controversy — brand-driven, not organic product traction
No published SWE-bench or Terminal-Bench scores
Trust story is messier than competitors due to RCE + corporate conflict history

OpenCode includes two built-in agents you can switch between with the Tab key.
Also included is a general subagent for complex searches and multistep tasks.
This is used internally and can be invoked using @general in messages.
