I think Claude Code is the moat (though I definitely recognize it's a pretty shallow moat). I don't want to switch to Codex or whatever the Gemini CLI is, I like Claude Code and I've gotten used to how it works.
Again, I know that's a shallow moat - agents just aren't that complex from a pure code perspective, and there are already tools that you can use to proxy Claude Code's requests out to different models. But at least in my own experience there is a definite stickiness to Claude that I probably won't bother to overcome if your model is 1.1x better. I pay for Google Business or whatever it's called primarily to maintain my vanity email and I get some level of Gemini usage for free, and I barely touch it, even though I'm hearing good things about it.
(If anything I'm convincing myself to give Gemini a closer look, but I don't think that undermines my overarching (though slightly soft) point).
1. using Claude Code exclusively (back when it really was on another level from the competition) to
2. switching back and forth with CC using the Z.ai GLM 4.6 backend (very close to a drop-in replacement these days) due to CC massively cutting down the quota on the Claude Pro plan to
3. now primarily using OpenCode with the Claude Code backend, or Sonnet 4.5 Github Copilot backend, or Z.ai GLM 4.6 backend (in that order of priority)
OpenCode is so much faster than CC even when using Claude Sonnet as the model (at least on the cheap Claude Pro plan, can't speak for Max). But it can't be entirely due to the Claude plan rate limiting because it's way faster than CC even when using Claude Code itself as the backend in OC.
I became so ridiculously sick of waiting around for CC just to like move a text field or something, it was like watching paint dry. OpenCode isn't perfect but very close these days and as previously stated, crazy fast in comparison to CC.
Now that I'm no longer afraid of losing the unique value proposition of CC my brand loyalty to Anthropic is incredibly tenuous, if they cut rate limits again or hurt my experience in the slightest way again it will be an insta-cancel.
So the market situation is much different than the early days of CC as a cutting edge novel tool, and relying on that first mover status forever is increasingly untenable in my opinion. The competition has had a long time to catch up and both the proprietary options like Codex and open source model-agnostic FOSS tools are in a very strong position now (except Gemini CLI is still frustrating to use as much as I wish it wasn't, hopefully Google will fix the weird looping and other bugs ... eventually, because I really do like Gemini 3 and pay for it already via AI Pro plan).
Google Code assist is pretty good. I had it create a pretty comprehensive inventory tracking app within the quota that you get with the $25 google plan.
