Bolt.new
- +Full dev environment runs in the browser via WebContainers, with the AI controlling filesystem, terminal, and server
- +Generates true full-stack apps (not just UI) and can deploy via Bolt Cloud
- +No local setup; fast for prototyping and iterating by chatting
- -Token-based usage cost can rise quickly on complex or long-running builds
- -Output needs human review and iteration; it is not a hands-off autonomous engineer
OpenAI Codex
- +One coding agent across cloud, terminal, IDE, and GitHub from a single account
- +Cloud tasks run in parallel in isolated sandboxes and return reviewable diffs and test logs
- +Open-source CLI with configurable sandbox and approval modes, plus MCP support
- -Agentic tasks require human review and approval; not a hands-off autonomous engineer
- -Cloud usage is rate-limited per 5-hour window and scales with plan tier
Which should you choose?
Bolt.new is prompt, edit, and deploy full-stack web apps in the browser, best for consumers, developers, smb. OpenAI Codex is openai's coding agent that writes, tests, and reviews code in the cloud, cli, and ide, best for developers, smb, enterprise. The right choice depends on the autonomy level you want, your existing integrations, and your budget, all compared above.
