Deno Deploy
Pros
- + V8 isolate architecture gives near-instant cold starts, second-scale deploys and automatic global replication
- + Genuinely usable free tier (1M requests/mo) and an honest $20/mo Pro plan with clear overage rates
- + Active-CPU billing instead of wall-clock billing rewards efficient handlers and makes idle apps free
- + TypeScript-native workflow with Deno's permission-based security model and broad Node/npm compatibility
- + Battle-tested substrate — Netlify edge functions run on the same infrastructure at 255M+ requests/day
Cons
- - Node compatibility is broad but not total — native modules and Node-specific tooling can still break
- - 99.95% SLA and SOC 2 Type 1 are Enterprise-only; Free and Pro have no contractual guarantee
- - The company has announced it is joining Cloudflare, adding platform-roadmap uncertainty
- - Not suited to long-running, connection-heavy or GPU workloads
- - Small-plan limits (one concurrent build on Free, low build-per-hour caps) can pinch teams
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)
