oh-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.
I use “all of them”. My primary harness is oh-my-pi. I probably use 10 different models on a regular basis.
I occasionally use OpenCode.
I try to use Codex and Antigravity as much as I can, often using it as a secondary agent (due to different usage pricing models than API). The same skills and MCPs work across harnesses.
Edit: I don’t use Claude Code simply because I already have enough to deal with and don’t see a major advantage to their harness. I use Opus credits from my Google subscription on the rare occasion I need them.
Cursor is also worth checking out particularly at the $20 a month price tier. If you have Grok you effectively already have it too.
I expect to have a completely different answer a year from now. The main “lift” we’ve gotten from AI tools is our clients now get an Android + iOS app + macOS app + Electron + PWA to go with whatever web based app they want us to build, at essentially the same original price. (There’s also a CLI and a TUI, but so far none of them care about that…)
We just made the decision to start adding MCPs to apps. Gonna be an interesting conversation in a few weeks when I can tell my business contact he can use his favourite chatbot to now plug in directly to the custom app he bought from me.
Nice, thanks for the write-up!
