Running Multiple Frameworks in a Single Project with Vercel Services

You can now deploy multiple frontends and backends together within a single Vercel project. With Vercel Services, you can deploy full-stack apps that use different frameworks under the same domain, with private communication between services and unified deployment/rollback capabilities.

All configuration is defined through the vercel.json file. Each service can have its own independent root directory and framework, with routing controlled via the Rewrites feature. In addition, the Service Bindings feature allows services to exchange data internally without going through the public internet, achieving both security and performance.

Key features include the following:

• Automated management: Vercel automatically handles routing, builds, and environment variable configuration.
• Unified dashboard: Supports service graph visualization, log filtering per individual service, and running a local environment via vercel dev.
• Framework-defined infrastructure: Automatically detects various frameworks such as FastAPI, Flask, Express, and Hono with zero configuration, and also supports Go and Rust.
• Efficient cost structure: Adopts an Active CPU billing model based on Fluid Compute, so you only pay for the time your code actually runs.
