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
  • Installnpm install -g opencode (or platform installer); opencode to start, opencode --cwd <path> to scope.
  • Slash commands/models, /share, /sessions, /themes, /editor, plus per-session config via opencode.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.
