The new OpenCode interface makes key generation simple: create the key in the console, connect it with opencode auth login, test the connection, and keep the key out of Git.

Package an Express and MongoDB app with Docker, push the image to Amazon ECR, and run it on ECS Fargate using a task definition, an execution role, and a service with a public IP. No EC2 instances to manage.

Install OpenCode, generate a free OpenCode Zen key, connect OpenRouter, and switch between free models when one hits a rate limit. No paid Claude plan and no local GPU.

Part 2 adds Kombai to the free stack and connects OpenCode to OpenRouter's free models. The result is a five-tool workflow for frontend work and terminal coding without a Claude subscription.

Antigravity 2.0, OpenCode, and BlackboxAI give you a Claude Code style workflow without a paid subscription or a local GPU. Install all three, connect a free model, and pick the one that fits how you code.

Claude Code has useful commands that are easy to miss: ultrathink for deeper reasoning, /caveman for terse output, /loop for repeated tasks, /clear and /compact for context control, and custom commands like /skeptic.
