OpenCode: FASTEST AI Coder + Opensource
Author / channel: WorldofAI Format: video Source: Original Published: 2025-07-01
Summary
WorldofAI walks OpenCode (github.com/sst/opencode) — SST’s open-source terminal AI coder. Differentiators vs claude-code and Gemini CLI: native themable terminal UI, parallel multi-agent support on the same project, shareable session links for collaboration, and native support for 75+ LLM providers through routers (Anthropic, OpenAI, Gemini, OpenRouter, Azure, Bedrock, Deepseek, Ollama, LM Studio). Demoes a SaaS landing page generation. Notes a “CLI battle royale” stress test where OpenCode was the last contestant standing against Gemini CLI and Aider.
Key Points
- Identity disambiguation — there was an earlier “OpenCode” project that was abandoned. This is a new project from SST, more polished and actively developed. Don’t confuse the two.
- What it has that Claude Code / Gemini CLI don’t:
- Native themable terminal UI (vs plain text)
- Parallel multi-agents on the same project
- Shareable session links for real-time collaboration
- 75+ LLM providers via routers (not locked to one ecosystem)
- LSP-aware code accuracy comparable to Claude Code
- Free model paths:
- Google Gemini 2.5 Pro free tier via AI Studio key
- OpenRouter free DeepSeek tiers
- Local: Ollama / LM Studio
- Install —
npm install -g opencode(or platform installer);opencodeto start,opencode --cwd <path>to scope. - Slash commands —
/models,/share,/sessions,/themes,/editor, plus per-session config viaopencode.json(providers, MCP servers, key bindings). - MCP support — local MCP servers configurable in
opencode.json.
Sponsorship & Bias Notes
No sponsor disclosed. WorldofAI does have a track record of overstating “this kills X” framings — the actual claim (“better-themed UI, parallel agents, BYO model”) is accurate; the headline is hype.
