Building APIs for SQL and NoSQL databases used to mean weeks of coding, testing, and securing endpoints. In 2025, that’s no longer the case. With no-code REST API builders, you can expose databases like Postgres, MySQL, SQL Server, Snowflake, MongoDB, and DynamoDB in minutes — complete with authentication, documentation, and scaling features.
This guide explores the 7 best no-code API builders you can use in 2025 to connect your SQL and NoSQL data sources, speed up development, and power AI/LLM workflows.
A no-code API builder is a platform that automatically generates endpoints for your databases. Some generate REST APIs, while others (like Hasura) specialize in GraphQL APIs with optional REST-like access. Instead of writing backend code, you configure CRUD operations, security, and integrations through a visual interface or pre-built connectors.
These tools make it easy to:
When evaluating no-code API builders, focus on:
Database Support → SQL (Postgres, MySQL, SQL Server, Snowflake) vs. NoSQL (MongoDB, DynamoDB, CouchDB).
API Type → REST-first vs. GraphQL-first (Hasura).
Ease of Use → Visual dashboards, auto-generated endpoints, and testing tools.
Security → API keys, OAuth, JWT, RBAC, and encryption.
Scalability → Ability to handle high request volumes as usage grows.
Integrations → Connectors for SaaS apps, analytics, or AI/LLM platforms.
DreamFactory auto-generates REST APIs for 20+ SQL & NoSQL databases. With built-in authentication, role-based access, and OpenAPI docs, it’s designed to serve teams of any size — from startups to large organizations.
Best For: Companies of all sizes needing secure, instant REST APIs across multiple databases.
Xano is a backend-as-a-service platform with a visual logic builder. It comes with a Postgres database by default and supports external data sources.
Best For: Teams building scalable apps that need custom workflows and database APIs without managing infrastructure.
NocoDB transforms SQL databases into APIs with a spreadsheet-style UI. It’s open source and flexible, supporting MySQL, Postgres, SQL Server, and SQLite.
Best For: Open-source teams wanting a self-hosted, flexible REST API solution.
Zapier is best known for automation but can connect APIs and SaaS tools via webhooks. It’s not a full database API tool, but perfect for lightweight integrations.
Best For: Non-technical users who need quick SaaS and API connections without backend coding.
Hasura is a GraphQL engine that instantly generates APIs over SQL databases like Postgres, Snowflake, SQL Server, and BigQuery. While it provides a REST-like layer, its true strength is real-time GraphQL APIs with advanced permissions.
Best For: Developers who prefer GraphQL and need real-time APIs with role-based access controls.
If you’re running MongoDB, Atlas App Services exposes API endpoints directly from your database. It includes triggers, authentication, and real-time sync.
Best For: Teams using MongoDB that want to quickly deploy APIs with built-in serverless features.
Apiary focuses on API design, documentation, and testing. While it doesn’t generate database APIs itself, it’s a strong complement to tools like DreamFactory or Hasura for lifecycle management.
Best For: Teams focusing on API design, collaboration, and documentation.
