I don’t understand Claude Code’s moat here. What can it do that opencode can’t or couldn’t fairly easily implement?
Code is not the moat, it's the gateway drug to their subscription (hence why they just locked other harnesses from using their subscription).
And the subscription is not Anthropic's moat either since it's likely heavily subsidized. They're just using it to acquire customers.
The moat is locking you into Anthropic's model particularities (extended thinking, getting you into their "mindset", etc.)
The moat is Anthropic's legal team and their ability to make legal threats.
Claude Code can be lower cost.
OpenCode: you pay per token.
Claude Code: you pay a flat fee.
The moat is in:
1. Opus and Sonnet.
2. Compute capacity. Anthropic has much more of it than your average coding startup.
3. The developing ecosystem around Claude Code.
