Supabase
Pros
- + Real PostgreSQL with SQL, extensions, migrations, and row-level security — no schema lock-in
- + Generous free tier: 50,000 MAU, 500MB database, unlimited API requests
- + Bundled auth, realtime, S3-compatible storage, APIs, and edge functions on one platform
- + Open source with a documented self-host path — a genuine exit if the managed service stops fitting
- + Transparent, detailed pricing page and 17 AWS regions to place data close to users
Cons
- - Bills grow legs: per-project compute, usage overages, and add-ons (PITR $100/mo per 7 days) stack up
- - Uptime SLA (99.9%) is Enterprise-only; support SLAs need the $599/mo Team plan
- - Free projects pause after a week of inactivity and skip automatic backups
- - Auth, realtime, storage, and functions layers are Supabase-specific to migrate away from
- - Scaling to high concurrency means moving to dedicated compute instances with sharp price steps
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)
