Supabase Edge Functions
Pros
- + 500,000 free invocations per month — enough for real workloads before paying anything
- + Zero-configuration access to Supabase Postgres, Auth and Storage from inside functions
- + Same open-source edge runtime locally and in production, with hot reload and CI deploys
- + Transparent per-million invocation pricing ($2 per million over quota) with spending limits available
- + Global distribution with optional pinning to the database region
Cons
- - Value largely depends on being a Supabase customer — weak standalone proposition
- - Cold starts are documented; not suited to heavy synchronous work in request paths
- - Deno/Node boundary still blocks some Node packages and native modules
- - No public uptime SLA below the Enterprise tier
- - External log drains cost $60 per drain per project
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)
