What is Vercel?

Vercel is a platform designed for the development, deployment, and hosting of modern Web applications and AI products; it is also the company behind Next.js. Developers can connect their code repositories, have preview environments generated automatically after each submission, and then release the approved versions across the global network.

It goes beyond traditional static website hosting; it also offers Functions, Fluid compute, caching, image optimization, storage, workflows, queues, monitoring capabilities, firewalls, as well as AI development tools such as AI SDK, AI Gateway, v0, and Vercel Agent.

What is Vercel suitable for?

• Deploy Next.js, React, and other front-end framework applications.
• Build a full-stack Web application with backend functions, a database, and authentication.
• Launch marketing websites, content sites, e-commerce front-ends, and enterprise portals.
• Develop chatbots, RAG, agents, and multimodal AI applications.
• Automatically generate shareable preview environments for each code branch.
• Execute scheduled tasks, persistent workflows, queues, and background processing.
• Improve access speed through global CDN, caching, and image optimization.
• Monitor the performance, traffic, operation logs, and errors of real users.

Core functions

• Git continuous deployment: Connect to GitHub, GitLab, or Bitbucket for automatic building and deployment.
• Preview Deployments: A separate preview address is generated for each submission, facilitating review.
• Global delivery network: automatic routing, TLS encryption, CDN caching, and compression.
• Vercel Functions: Executes server-side logic, APIs, and AI-based streaming responses.
• Fluid compute: Reuse instances and charge based on the active CPU usage and configured memory.
• Storage and configuration: Offers Blob, global configuration, and Marketplace data services.
• Workflows and Queues: For handling long-running tasks, retries, waiting, and asynchronous messages.
• Web Analytics and Speed Insights: Monitor traffic and the performance of real users.
• Vercel Firewall: Offers WAF, rate limiting, IP rules, and DDoS mitigation.
• AI development suite: AI SDK, AI Gateway, v0, Agent, and Sandbox.

The workflow from code to deployment

Once the developer connects to the code repository, Vercel will execute the build process whenever a commit or merge is made. Preview versions are available for design, product, testing, and customer approval, while the main branch is released to the production environment in accordance with the project’s guidelines.

• Automatically identifies common frameworks and build commands.
• Manage deployments separately for branches, pull requests, and the production environment.
• Use environment variables to distinguish between development, preview, and production credentials.
• Comment directly on the preview page and check for layout changes.
• In case of problems, it is possible to quickly roll back to a previous deployment.
• Complex projects can take advantage of custom environments, rolling releases, and access controls.

Vercel Functions and Fluid compute

Vercel Functions is used to execute dynamic server-side code, and it is suitable for handling APIs, authentication processes, Webhooks, as well as AI inference tasks. Fluid compute reduces cold starts by reusing computing instances, and it separates the measurement of CPU usage time from that of allocated memory.

• It scales automatically based on requests, eliminating the need for ongoing server management.
• It supports streaming responses, making it suitable for outputting AI-generated content character by character.
• Reduce idle CPU waste while waiting for the database or model to return.
• It can be used in conjunction with caching to reduce redundant executions and associated function costs.
• Use regional configuration to bring computing closer to the data or users.
• Production applications still need to manage timeouts, concurrency, connections, and retries.

AI SDK

The Vercel AI SDK is an open-source AI toolkit for TypeScript and JavaScript, offering a unified interface for various model providers. Developers can use it to create text generation capabilities, structured outputs, tool calls, embeddings, chat interfaces, and agents.

• Standardize calls to different model providers to reduce differences in application-layer interfaces.
• It supports the generation of text, stream text, and structured objects.
• It provides capabilities for environments such as React, Next.js, Vue, Svelte, and Node.js.
• It supports chat status, message streams, and integration with the front-end UI.
• Tools can be defined to enable the model to query data or perform controlled actions.
• It supports embedded and retrieval-enhanced generation workflows.
• It can be connected to the AI Gateway, or models from model providers can be used directly.

AI Gateway

AI Gateway utilizes a set of authentication mechanisms and interface connections to access hundreds of models for text, images, videos, and audio. The provider currently promises no additional charges for these model tokens, nor any platform fees; instead, billing is carried out based on the prices published by the model providers.

• One key allows access to multiple models and various modalities.
• Uniformly record calls, models, tokens, latency, and costs.
• Automatic fallback is configured in case of a failure of the model or provider.
• Set routing policies based on availability, cost, or latency.
• Supports using the provider’s own model keys.
• Set budgets centrally for the team, and allow for model and data policies.
• The free tier covers only some models and comes with speed restrictions; a full catalog requires the purchase of credits.

AI Gateway billing method

v0

v0 is Vercel’s AI-powered product for creating and designing interfaces; it allows users to create and modify pages, components, and full-stack applications through dialogue. It works in conjunction with Vercel’s deployment services, the Next.js ecosystem, and the v0 Platform API, but it comes with its own separate pricing model.

• Generate initial versions of websites and applications from natural language descriptions.
• Modify the page based on screenshots, files, or feedback.
• Run code in the dialog, fix errors, and preview the results.
• Connect to databases, authentication, and other application services.
• Sessions can be created and read programmatically using the official v0 SDK.
• The generated code still needs to be checked for business logic, security, and maintainability.

Vercel Agent

Vercel Agent is an AI assistant built into the platform; it can be used to investigate issues by taking into account information related to projects, deployments, logs, metrics, configurations, usage levels, and code repositories, to review code, and to carry out approved actions.

• Ask about deployment and production issues in the dashboard or Slack.
• Perform code review on pull requests and provide validated suggestions.
• Analyze logs and metrics to identify production failures.
• Use a secure sandbox to reproduce issues and run checks.
• Perform the permitted actions after user approval.
• Current features such as chatting, surveys, and code reviews may still be in the testing phase.

Vercel Sandbox

Sandbox provides an isolated, temporary computing environment that can be used to run untrusted code, validate generated code, and carry out agent tasks. Vercel Agent also makes use of secure sandboxes to reproduce issues.

• Run the code generated by AI and observe the results.
• Isolate the dependency installation, build, and testing processes.
• Provide controlled terminal and file environments for agents.
• Use snapshots to reduce the time required to create environments repeatedly.
• Set boundaries for resources, network, duration, and credentials.
• Sandboxes do not automatically eliminate the risks of supply chain and data breaches.

Workflows, Queues, and Cron

• Workflows are suitable for tasks that require pausing, resuming, retrying, and running for extended periods.
• Queues are suitable for converting bursty requests into manageable asynchronous processing.
• Cron Jobs are used to trigger cleanup, synchronization, or reporting tasks at regular intervals.
• AI applications can use workflows to handle multi-step agents and manual approvals.
• Queues can protect database and model services from sudden spikes in concurrency.
• It is necessary to design idempotent logic and error recovery for repeated executions.

Global network and caching

The Vercel Delivery Network offers global access points, automatic routing, TLS encryption, compression, and caching. Static resources and cacheable responses can be delivered from the nearest location, thereby reducing the number of calls to backend functions and data transmission.

• TLS certificates are automatically configured for custom domain names.
• Use CDN to cache static content and dynamic results that are eligible for caching.
• It supports re-verification in the background as well as incremental static regeneration.
• Control the request path through rewriting, redirection, and middleware.
• Enterprise solutions offer multi-region computing and automatic failover.
• Incorrect caching policies can lead to outdated content, privacy breaches, or high costs associated with data retrieval from the origin server.

Images, Blobs, and Global Configuration

• Image Optimization converts images based on device and request, and utilizes caching.
• Blobs are used to store uploaded files, images, and other objects.
• Global Config is used to enable or disable the low-latency reading feature or for global configuration.
• Marketplace can be connected to third-party databases, caches, and other services.
• Developers need to pay attention separately to storage, the number of operations, and billing for reads, writes, and transfers.
• User-uploaded content should undergo checks for file type, size, viruses, and access control.

Observability and analysis

• The Usage Dashboard is used to view the consumption of various infrastructure resources.
• Web Analytics tracks visit events and basic traffic performance.
• Speed Insights collects real user performance metrics.
• Runtime Logs allows you to view logs from the function’s compilation and execution phases.
• Session Tracing links user requests with backend executions.
• Observability Plus enhances query, metric, alerting, and retention capabilities.
• AI Gateway provides model invocation, cost, and latency monitoring.

Security capabilities

• Web Application Firewall and custom firewall rules.
• Automatic DDoS mitigation, IP blocking, rate limiting, and challenge mode.
• Multi-factor authentication, team roles, and deployment access protection.
• Pro offers optional SAML SSO, HIPAA BAA, and advanced deployment protection.
• Enterprise offers SCIM, directory synchronization, and more detailed access control for individual items.
• Features such as auditing, Managed WAF, Secure Compute, and BYOC are available depending on the plan selected.
• The development team is still responsible for implementing its own authentication, authorization, and data security measures.
