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
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
