Pros

Provider-agnostic open-source agent (TUI, desktop, IDE extension); automatic LSP detection; free models plus BYOK across 75+ providers; OpenCode Go (~$10/mo, $5 first month) bundles curated open coding models with generous limits — usable in OpenCode or any agent via API key.

Cons

Smaller commercial support footprint than Cursor/Claude Code; Go is a curated low-cost lineup (not full frontier Claude/GPT) — Zen pay-as-you-go or BYOK for broader models.
