Vercel Services

6/30/2026

Introduces Vercel Services, a new capability allowing multiple frameworks (frontend, backend, etc.) to be deployed and managed within a single Vercel Project. This enables atomic deployments, shared preview deployments, and internal service communication via service bindings configured in `vercel.json`. The post details how services are declared, routed, and visualized in the Vercel UI, and how service bindings facilitate internal communication using environment variables. It also highlights framework-defined infrastructure, isolated compute for agents (Vercel Sandbox), WebSocket support, Vercel Connect for external service access, database and storage integrations, and background job processing (Queues, Workflow, Cron).

This post details how Waldium leverages Vercel for Platforms and Vercel Middleware to serve over 500 customer blogs and their respective MCP server endpoints from a single Next.js deployment. It highlights the dynamic routing capabilities of Vercel Middleware for tenant identification and the Vercel Domains API for scalable custom domain and SSL certificate management, enabling rapid provisioning of MCP endpoints for new customers.

This post showcases how Relevance AI uses the Vercel REST API for autonomous agent actions across various tools, and how Leonardo.AI achieved significant improvements in build times (10+ mins to 2 mins) and page load times (60s to ~3s) after migrating to Vercel. It emphasizes Vercel Observability and Fluid compute for automatic scaling and issue detection, enabling lean operations for AI-native startups.

This post highlights how Sensay leveraged Vercel's platform, specifically preview deployments, feature flags, and instant rollbacks, to achieve rapid product development and iteration. It emphasizes the platform's ability to enable startups to ship without a dedicated DevOps team, reducing infrastructure costs and accelerating the path to product-market fit. The use of Next.js for the frontend, Hono for the API, and the Vercel AI SDK for AI features is also mentioned as part of their hybrid architecture.

Introduces zero-configuration deployment for popular Python (FastAPI, Flask) and TypeScript (Express, Hono, NestJS, Nitro) backend frameworks on Vercel, leveraging Framework Defined Infrastructure (FDI). This enables automatic provisioning of infrastructure based on framework conventions for scaling, routing, and compute. Also introduces Active CPU Pricing for Fluid compute, billing only for active execution time, and Durable Orchestration via the Workflow Development Kit (WDK) for long-running, reliable agents and backends with integrated observability. A beta Vercel Python SDK is also available for accessing Vercel products and services.

This post details Vercel's response to the AWS us-east-1 outage, highlighting the resilience of its multi-region architecture for serving production traffic. It explains how Vercel's stack is designed to survive the loss of any single region and details the cascading failure that affected its global caching infrastructure, leading to temporary disruption of static file serving. The post also describes a secondary incident impacting Vercel's control plane due to a feature flag provider outage, which affected the dashboard, APIs, and builds but not production traffic serving. Mitigations and restoration efforts for both incidents are outlined, emphasizing the importance of regional fault tolerance and the need for further improvements to prevent any request drops.

This post introduces benchmarks comparing Vercel's Fluid compute against Cloudflare Workers for server-side rendering. It highlights Fluid compute's advantages in performance (1.2-5x faster) and consistency due to in-region deployment, full Node.js/Python runtime compatibility, and configurable concurrency/resource allocation. The benchmarks demonstrate significant improvements for frameworks like Next.js, React SSR, and SvelteKit, as well as compute-bound tasks.

Introduces Visual Editing as a joint solution with Sanity, enabling a one-click path from Vercel's Preview Deployment interface to Sanity Studio for content editing. This enhances collaboration between developers and marketers by allowing visual editing of content directly on the frontend, regardless of where it's reused. It also highlights the composable web architecture enabled by Vercel and Sanity, citing examples like Loom, and emphasizes the benefits of decoupling frontend and backend for developer workflow, user experience, and content management.
