When Your Competitor Blocks You, You Win

Opencode: 650K to 13M users in 6 months. 20X growth. Here's the playbook.

January 2026: Anthropic blocked Opencode from using Claude subscriptions. Backfired. Suddenly Opencode and Claude Code were equals. Users took notice.

How they won:

1. Anthropic's block became free marketing. Inbound exploded.

2. Open-source models hit parity (Kimi 2.5 in Feb). Opencode was the only harness supporting 70+ models.

3. Built for developer taste. Terminal UI like NeoVim, not a toy. Founder Jay V spent 16 years learning what devs want.

4. Global arbitrage. 24-hour GPU utilization. Better unit economics than US-only competitors.

Result: $40M ARR. 7 trillion tokens/day. Enterprises begging to sign security agreements.

Lesson: Persistence + taste + timing = exponential growth.
