alt Hacker Newsoh-my-pi is a bit of a cross between the two; comes with basically everything OpenCode does, but still easy to customise.
OpenCode is nice if you don't want to do a lot of research and just want to get started right away. The OpenCode Go plan for $5 a month for your first month is a great way to do this, with good models to choose from and reasonable usage limits for a beginner.
I use Go plan precisely with Opencode IDE (and also Jetbrains IDE suite), but now also have access Gemini Pro and Claude Pro. And wonder which tooling to invest my time into, especially that MCP servers also potentially come into play here, and I want at least some models/tools to handle private tasks, like handling my increasingly-complex Home Assistant setup. And I also want to start using models according to needs (plan, execution, reviews). This shit gets extremely complicated extremely quickly, not to mention how often this field shifts direction.
