JetBrains' LLM-agnostic coding CLI. BYOK pricing (just API key costs), one-click migration from Claude Code/Codex, works in terminal + IDE + CI/CD + GitHub/GitLab. Beta launched 2026-03-09. No public repo.
Where it wins
JetBrains distribution: 11M+ paid IDE seats — largest potential install base in the category
BYOK pricing: just pay for API keys, no additional subscription
One-click migration from Claude Code and Codex CLI
LLM-agnostic — not tied to any model vendor
Works in terminal + IDE + CI/CD + GitHub/GitLab
Where to be skeptical
No public GitHub repo — independent verification impossible
No published benchmark scores
Beta only — no independent reviews or community adoption data yet
Launched 2026-03-09 — fewer than 2 weeks of public exposure
Editorial verdict
Too early to rank — no public artifact (no repo, no benchmark, no independent review). JetBrains has 11M+ paid IDE seats; if the JetBrains installed base converts, this becomes a serious Tier 2 contender within 60 days. Check back after first independent comparisons.
