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
Cloudflare Workers
Pros
- + No cold starts: V8 isolates start in microseconds at 330+ locations
- + CPU-time billing with a genuinely usable free tier (100k requests/day)
- + No egress or bandwidth charges on any plan
- + Storage stack (KV, D1, Durable Objects, R2) binds declaratively and stays in-network
- + Strong docs: pricing and limits pages are explicit and example-driven
Cons
- - CPU time caps exclude compute-heavy and long-running workloads
- - Real vendor lock-in through Durable Objects, bindings and deployment model
- - KV writes ($5.00/M) and Durable Objects duration billing surprise stateful designs
- - Conceptual shift for teams used to container-based serverless
- - No uptime SLA below the Business plan
