Full review →What is Bolt.new?
Bolt.new by StackBlitz is a browser-based AI development environment that lets you build, run, and deploy full-stack web applications entirely in your browser tab. Powered by WebContainers technology, it runs a real Node.js runtime natively in the browser without requiring any server. You see changes live as the AI generates code, with hot reloading and a real terminal. The workflow starts with a prompt describing what you want, and Bolt generates the complete project with file structure, dependencies, frontend, and backend logic. You can iterate by chatting, requesting changes, fixing bugs, or adding features conversationally. When ready, deploy to Netlify, Vercel, or any hosting provider with one click. Bolt handles React, Next.js, Vue, Svelte, and other modern frameworks. The free tier provides limited daily tokens, Pro ($20/mo) offers generous usage, and Team ($50/mo) adds collaboration and priority access. The tool is best suited for quick prototyping, hackathons, building mvps. It offers a free tier alongside paid plans (Free · Pro $20/mo · Team $50/mo), making it accessible for individuals and teams alike.
What is Replicate?
Replicate is a cloud platform for running open-source AI models through a simple API, eliminating the need to manage GPU infrastructure. The platform hosts thousands of community-contributed models covering image generation, video generation, language models, audio processing, image editing, and specialized ML tasks. Any model published on Replicate can be called with a single API request, with Replicate handling the GPU provisioning, scaling, and infrastructure management automatically. Model creators can publish their own models using Cog, an open-source tool that packages ML models into production-ready containers. Pricing is purely usage-based with per-second billing for GPU time, meaning you pay only for actual compute with no idle costs. Popular models include Stable Diffusion, Whisper, Llama, and hundreds of specialized image processing models. Replicate is essential for developers who need access to diverse AI models without maintaining their own GPU infrastructure, and for researchers who want to share and monetize their models. The tool is best suited for developers wanting to quickly prototype with open-source ai models. Pricing starts at Pay per second of compute · Predictions from $0.00025.

Frequently asked questions
Bolt.new vs Replicate — which one should I pick?
It depends on the job. Bolt.new is strongest at in-browser full-stack app builder powered by StackBlitz + Claude. Replicate is strongest at API for running open-source ML models in the cloud. Pick Bolt.new if its strength matches your daily work, and Replicate if the second description matches better. There is no objectively 'better' answer — only the better fit for the specific work you do most often.
Is Bolt.new or Replicate cheaper?
Bolt.new pricing: Free · Pro $20/mo · Team $50/mo. Replicate pricing: Pay per second of compute · Predictions from $0. Pricing alone is rarely the right reason to choose between them — the wrong tool at half the price still wastes your time.
Does Bolt.new or Replicate have a free plan?
Free-tier availability changes frequently for both Bolt.new and Replicate. Check the official site before signing up — never trust a third-party page (including this one) to be perfectly up to date on plans.
Can I use Bolt.new and Replicate together?
Yes — there is no technical or licensing reason you cannot use Bolt.new and Replicate side by side. Many people do exactly this: Bolt.new for in-browser full-stack app builder powered by StackBlitz + Claude, Replicate for API for running open-source ML models in the cloud. The only cost is paying for two subscriptions if you upgrade both.
What does Bolt.new do that Replicate cannot?
Bolt.new's honest edge over Replicate is in-browser full-stack app builder powered by StackBlitz + Claude. Replicate cannot match this directly — though it has its own edge (API for running open-source ML models in the cloud). If your daily work depends on what Bolt.new is uniquely good at, that is the deciding factor. Otherwise feature parity will probably feel close enough.
