Zuplo
Pros
- + TypeScript policy code lives in your own repository with GitOps deployment and per-branch previews
- + Free tier is genuinely usable: 100K requests/month, 300 edge locations, unlimited environments
- + AI Gateway, MCP Gateway and hosted developer portal included on every plan, not sold as add-ons
- + Publishes its pricing, including the Enterprise floor - rare in the API gateway category
- + Auto-scaled edge deployment across 300+ locations with no cluster to manage
Cons
- - Builder overage of $100 per additional 100K requests makes steady growth expensive
- - No SLA of any kind below Enterprise, and only 99.5% at the Enterprise entry level
- - Both Free and Builder cap the team at 2 developer seats; SSO/RBAC is Enterprise-gated
- - Analytics beyond live logs is a 14-day trial on the lower tiers
- - Small, 2021-founded company: thinner community and plugin ecosystem than Kong or AWS API Gateway
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)
