Serverless free tiers are strongest for short, request-driven work: APIs, form handlers, webhooks, scheduled tasks and edge logic. They avoid managing a server, but exchange that freedom for execution, runtime, deployment and bandwidth limits.
Use Cloudflare Workers for edge APIs, webhooks and high request efficiency.
Use Vercel Functions when the backend belongs to a Next.js application.
Use Netlify Functions for Jamstack sites and repository-driven workflows.
Use Firebase or Supabase when functions must sit beside a managed app backend.
Best edge functions
Best for
Hono APIs, middleware, webhooks, redirects and globally distributed logic
Workers runs near users with a request-based Free plan and no traditional idle server to wake.
Best for Next.js
Best for
Next.js route handlers, server actions and frontend-adjacent APIs
Vercel integrates deployments, previews and functions directly with the Next.js workflow.
Best Jamstack workflow
Best for
Form handlers, site APIs and functions deployed beside a static frontend
Netlify combines Git deployments, previews, CDN hosting and functions in one project.
Best managed backend ecosystem
Best for
Functions triggered by auth, database, storage or Google services
Firebase connects functions to Authentication, Firestore, Hosting and event sources.
Choose Cloudflare for edge-first APIs and webhooks, Vercel for logic embedded in Next.js, Netlify for a static-site repository workflow, and Firebase for events tied to managed backend products. The best integration is usually more important than the largest headline request quota.
Keep functions stateless and idempotent. Store data in a database or object store, validate every public input, set timeouts on outbound calls and move long work to queues. Reuse database connections where the runtime permits it and test concurrency limits.
Count execution, bandwidth, build minutes, log retention, database operations and third-party API calls together. A function can be free while its database or egress is not. Add alerts before publishing and never rely on a free plan as an uptime guarantee.

Cloudflare Workers is a strong general choice for edge APIs. Vercel fits Next.js, Netlify fits Jamstack sites, and Firebase fits event-driven applications already using its backend services.
It does not usually sleep like an idle web server. The platform starts execution for requests, but cold initialization and execution limits can still affect latency.
Sometimes after adaptation, but not as a permanent process. Long jobs, native modules, local state, arbitrary sockets and background workers may be incompatible.
Small production workloads can fit free quotas, but configure spend controls and monitoring. Traffic spikes, bandwidth and downstream database calls can move the project into paid usage.
