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
OpenRouter
- +One OpenAI-compatible API and key for 400+ models across 70+ providers, with trivial model switching
- +Provider routing and automatic fallback pool uptime across providers for higher availability
- +States it does not mark up inference (provider pass-through pricing); free models and BYOK available
- -Adds a fee on credit purchases (around 5.5% pay-as-you-go) on top of provider rates
- -It is a routing layer, not an agent: it provides model access, not autonomous task execution
