Convex
Pros
- + Replaces a whole backend stack — database, functions, sync, search, storage and auth — with end-to-end TypeScript type safety and ACID transactions
- + Generous economics for reactive apps: query/mutation compute free on serverless, plus a real free plan and pay-as-you-go Starter tier
- + All unit rates and per-tier limits published, including an honest 1.3x regional multiplier for EU and Canada
- + Core backend open-sourced (March 2024) with self-hosting option — genuine lock-in relief uncommon in this category
- + Well-funded ($110.5M through a $57M Series B in 2026), SOC 2 Type II, HIPAA compliant, with named production customers at real scale
Cons
- - Document model is not SQL — poor fit for Postgres estates, analyst workflows and BI tooling
- - Usage-based metering can surprise chatty clients; no hard spend caps on paid tiers
- - Support SLAs are a paid feature: 30-minute P1 response only in $1,000–$2,000/month premier tiers
- - TypeScript-first to the point of exclusion — a non-starter for non-TS teams
- - Self-hosting the open-source backend is an operational project most teams will only use as an escape hatch
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)
