Vercel
Pros
- + Best Git-to-URL developer workflow on the market, with per-PR preview deployments
- + Deepest Next.js integration anywhere — framework features land here first
- + Real free Hobby tier with hard caps (pause, not bill) and clear per-service pricing tables
- + Fluid compute narrows the serverless tax: active-CPU billing plus instance reuse
- + Reliable global delivery: 100+ edge locations, multi-region function failover, 99.99% targets
Cons
- - Cost scales aggressively: bandwidth, invocations, ISR, and builds stack into bill shock
- - Function timeouts, payload caps, and no root access limit what can run
- - Platform-specific features (ISR cache, Edge Config, Fluid) accumulate into lock-in
- - Hobby is non-commercial and pauses on overage; support below Enterprise is thin
- - Heavy compute economics are poor compared to containers or VMs
Azure Functions
Pros
- + Permanent free grant of 1 million executions and 400,000 GB-s per month
- + Trigger/binding integrations cover most Azure and third-party services declaratively
- + Durable Functions for stateful orchestration — the strongest workflow story among serverless platforms
- + Hosting plan ladder (Consumption, Flex, Premium, Dedicated, Container Apps) covers most cost/performance points
- + 99.95% SLA with service credits scaling up to 100% below 95% uptime
Cons
- - Cold starts on Consumption hurt latency-sensitive HTTP workloads
- - Per-instance limits (1.5 GB RAM, 1 core) cap what single functions can do
- - Azure surface area: storage account, monitoring, identity, and networking costs stack up
- - Bindings and Durable Functions abstractions lock integration logic to Azure
- - Premium costs real money whether or not traffic flows (EP1 ~$146/month US rates)
