OpenCode: The Agent You Actually Own
You already use an AI coding agent. This deck is about who owns the harness around it — model, workflow, and context lock-in, and the open alternative.
You already use an AI coding agent. The interesting question is not whether agents work — it is who owns the harness around them.
A closed harness costs you three times: model lock-in, workflow lock-in, and context lock-in. The subscription is the smallest of the three. This is the deck from the JaxNode meetup on what an open, model-agnostic, config-as-code harness actually buys you.
Presented to JaxNode on October 22, 2026.
What’s inside
- The three lock-ins of a closed harness — and why the subscription is the smallest cost
- What OpenCode is: MIT licensed, 75+ providers, config-as-code, terminal / desktop / IDE
- The real pricing picture: 46 free models, the $10 Go tier, or bring your own key
- An honest comparison with Claude Code, Cursor, and Codex — including where they still win
- The plan-where-thinking-is-free, build-where-the-code-lives workflow
- Six keys you will actually press, and guardrails that hold
- AGENTS.md, skills, plugins, and MCP servers — what to install and how to judge it
- Hands-on workshop appendix: setup checklist and three graded exercises
