Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deep Code

Model choice is narrow. Bring your own key covers DeepSeek-V4-Pro and Flash plus the GLM and Mimo coding plans, and no frontier model from OpenAI, Anthropic or Google.
The Pro tier caps included usage at 100 Pro Credits per day rather than offering an unmetered plan.
Bring your own key is a paid feature, so the free tier cannot be pointed at your own DeepSeek account.
Desktop only, with no editor extension, web version or team seat management as of September 2026.
A small, young vendor with no independent review coverage yet, so there is nothing outside the vendor's own site to corroborate the cost claim.

Smaller ecosystem compared to React or Vue
