Bolt.new vs Replicate
A side-by-side comparison of capabilities, autonomy, integrations, and pricing to help you choose.
Short answer: choose Bolt.new if you want prompt, edit, and deploy full-stack web apps in the browser (Supervised agent, freemium); choose Replicate if you want run and fine-tune open-source ai models with a cloud api, billed per second (Assistant, usage).

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
Replicate
- +Huge catalog of open-source models runnable with a single API call, no GPU provisioning
- +Transparent per-second (or per-output) usage billing that scales to zero when idle
- +Cog lets you package and deploy your own models on the same managed infrastructure
- -It is inference infrastructure and tooling, not a turnkey agent; you build the application around it
- -Cold boots can take tens of seconds to minutes for rarely-used models and are billed at the running rate, so latency and cost can be unpredictable without warm deployments
Which should you choose?
Bolt.new is prompt, edit, and deploy full-stack web apps in the browser, best for consumers, developers, smb. Replicate is run and fine-tune open-source ai models with a cloud api, billed per second, best for developers, smb, mid-market. The right choice depends on the autonomy level you want, your existing integrations, and your budget, all compared above.
