api0.app vs Zuplo

api0.app combines a no-code API builder with a marketplace for publishing and finding APIs. Its visual builder turns tables or defined fields into typed REST endpoints with request validation and pagination. Supported sources include Postgres, MySQL, SQLite, MongoDB, Google Sheets, CSV uploads and existing REST APIs. Each endpoint has an interactive reference and a downloadable OpenAPI 3.1 specification that updates when the schema changes. Generated APIs are private by default, and marketplace publication is optional. Access features include scoped API keys, secret rotation and rate limits that vary by plan. Publishers can charge per request, offer monthly plans or provide a free tier; the platform meters requests, bills buyers and pays builders monthly after a marketplace fee. The dashboard reports request volume, error rate, p95 latency and revenue by endpoint, including customer-level details. The Free plan costs nothing and includes up to 2 live endpoints and 10,000 requests per month.

Zuplo is an API management platform with API Gateway, AI Gateway, and MCP Gateway products. API protections include API keys, JWT, Basic Auth, mTLS, bot detection, rate limiting, and schema validation. OpenAPI supports documentation and cataloging, and every plan includes a hosted developer portal that can use a customer domain. The AI Gateway routes requests among OpenAI, Anthropic, Google, and Mistral, and offers semantic caching, prompt injection protection, secret masking, and spending budgets. MCP Gateway is included on every plan for authenticating, routing, and governing MCP servers. Documented logging integrations include AWS CloudWatch, Datadog, Dynatrace, New Relic, Google Cloud Logging, Loki, Splunk, Sumo Logic, and VMware Log Insight. Zuplo says its gateways deploy to more than 300 edge locations; self-hosted or dedicated deployment is available. GitHub GitOps is supported on Free and Builder, while Enterprise lists GitHub, Bitbucket, GitLab, and Azure DevOps. Free costs nothing and includes up to 100K monthly requests. Builder costs $25 a month, with additional requests charged at $100 per 100K.
