    Vercel Overview

    Vercel is a developer platform and AI Cloud designed to build, deploy, and scale modern web applications with speed and security. It streamlines the path from local code to global production with Git-connected deploys, automatic HTTPS, and globally performant infrastructure, while giving teams powerful collaboration tools like preview deployments and in-context commenting. For engineering organizations shipping React/Next.js and other frontend frameworks, Vercel reduces operational overhead and accelerates iteration through zero‑config primitives, instant rollbacks, and route-aware observability. Beyond core hosting, Vercel’s AI capabilities make it easy to prototype and ship AI features. The Vercel AI Gateway provides a single, unified interface to major LLM providers with a shared credit wallet, while prebuilt templates let teams deploy AI apps in minutes and stream long-running LLM responses. Enterprise-grade security and deployment protection controls help teams test and share safely, with flexible bypass options for E2E testing and collaboration. Whether you’re a startup launching fast or an enterprise with strict governance, Vercel offers the infrastructure, DX, and AI tooling to deliver faster, more personalized web experiences.

    Key Features & Capabilities

    Git-Connected Deploys

    Push to Git or deploy from the CLI and go from localhost to globally available HTTPS in seconds. Every push creates a production-grade preview, enabling safe, frequent releases with minimal configuration.

    Collaborative Previews

    Preview deployments let teams discuss changes on real UI rather than static designs. Stakeholders can review and comment, speeding feedback cycles and improving quality before production.

    Route-Aware Observability

    Built-in analytics monitor performance, traffic, and function invocations by route. Teams can pinpoint hotspots across pages like Homepage or Checkout to optimize user experience proactively.

    Vercel AI Gateway

    Access all major LLMs through one unified interface and a shared AI credit wallet. Stream responses with zero-config infrastructure and scale AI workloads globally without managing model integrations.

    Microfrontends Local Development Proxy (Beta)

    Run a single microfrontend locally while proxying other routes to production for seamless end-to-end testing. Works with Turborepo or standalone, reducing setup time and boosting developer velocity.

    Frequently Asked Questions

    Is there a free plan for Vercel?

    Yes. You can start building with a free account. The site explicitly invites users to “Start building with a free account,” with Pro and Enterprise options available for advanced needs.

    Are Beta features covered by the Enterprise SLA?

    No. Products in Beta are not covered under the Enterprise Service Level Agreement and are not recommended for full production use.

    How can I share protected preview deployments with external stakeholders?

    Use Shareable Links to grant access via a secure URL parameter (available on all plans). For automated access (e.g., E2E tests), enable Protection Bypass for Automation and use the generated secret.

    What if my protected deployment needs CORS preflight support?

    Add paths to the OPTIONS Allowlist so preflight OPTIONS requests bypass protection. Requests starting with the listed paths and method OPTIONS will be allowed.

    Can I use Deployment Protection Exceptions?

    Yes, on Enterprise plans or Pro with the Advanced Deployment Protection add-on. Exceptions make specified preview domains publicly accessible, bypassing authentication, password protection, and trusted IPs.

    How do I develop microfrontends locally without running every app?

    Use the microfrontends local development proxy from @vercel/microfrontends. Run a single app locally and proxy other routes to production. It works automatically with Turborepo or via a direct proxy command.

    How do I fix a MALFORMED_REQUEST_HEADER error in a Vercel Function?

    Validate header formatting and ensure values (especially cookies) are valid UTF‑8. Inspect request headers for syntax or name/value issues and confirm your function logic isn’t producing malformed headers.
