Visit Bolt.newBottom line
Codex (OpenAI) is the clear winner: 8.3/10 (A-tier) versus 6.5/10 (C-tier). Bolt.new isn't a bad tool, but on every category that drives the overall score, Codex (OpenAI) comes out ahead. The tier gap is repeatable -- not methodology noise -- and the day-to-day experience reflects it.
Pricing-wise, both tools have a free tier (Codex (OpenAI) starts $0, Bolt.new starts $0), so you can test either without committing. Compare what each free tier actually unlocks -- usage caps, model access, and feature gates differ a lot more than the headline price suggests, especially as both vendors have tightened limits in 2026.
By use case: pick Codex (OpenAI) when developers already paying for chatgpt plus who want a coding agent at no extra cost. Pick Bolt.new when non-developers who want to quickly prototype a web app idea and don't need production quality. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in Codex (OpenAI)'s lane, the tier-list ranking and the use-case fit point the same direction; if you're in Bolt.new's lane, the score gap matters less than the fit.
Bottom line: Codex (OpenAI) is the better tool for most people right now. Pick Bolt.new only when non-developers who want to quickly prototype a web app idea and don't need production quality -- that's its lane, and inside that lane it still earns its place.
