Build Scalable Backends With Visual API Creation

Building custom backend systems typically requires extensive coding knowledge and tons of development time. You need APIs, database setups, server configurations, and workflow automations—all before your actual product can take shape. This technical overhead leaves you feeling stuck in development limbo rather than shipping your product.

What is fastgen

Fastgen is a visual API and workflow builder with an integrated Postgres database that accelerates backend development. Using its drag-and-drop interface, you can rapidly create custom APIs, automate workflows, and manage database operations without writing server-side code. The platform handles the technical complexity of backend development, allowing you to build, test, and deploy scalable backends and automations in a fraction of the traditional development time.

Key Capabilities

Visual API Builder : Create REST endpoints, set up authentication, and define validation rules through an intuitive drag-and-drop interface, reducing API development time from days to hours.

Integrated Postgres Database : Generate database schemas and CRUD operations automatically with a click of a button, eliminating manual database setup and maintenance tasks.

Real-time Debugging : Test API endpoints and workflows instantly with detailed logs for each action, helping you identify and fix issues faster without switching between multiple tools.

Third-party Integrations : Connect to any service that has an API without complex authentication handling, enabling smooth data flow between your backend and external services.

One-click Deployment : Deploy your backend with a single click with no DevOps knowledge required, as Fastgen handles hosting and infrastructure management automatically.

Perfect For

A startup founder with minimal technical background needed a custom backend for their mobile app. Using Fastgen, they created API endpoints and database operations in days rather than weeks, getting to market faster while saving thousands on development costs.

A development team at a midsize company needed to modernize legacy systems with new API integrations. Fastgen allowed them to rapidly prototype the backend, test extensively, and deploy a production-ready solution while their developers focused on more complex business logic.

Worth Considering

Fastgen is primarily focused on backend development and doesn't offer frontend building capabilities. While ideal for API-centric projects, you'll need to pair it with a separate frontend tool for full-stack development. The platform is limited to Postgres for database operations, which may be restrictive if your project requires other database types. Pricing follows a tiered plus usage-based model (Freemium, $$-$$$) with flow run limitations based on action blocks executed.

Also Consider

Xano: More established platform with a larger user community and extensive integration options if you need a more mature no-code backend solution.

Backendless: Better choice if you need an all-in-one platform with both frontend and backend capabilities in a single environment.

Supabase: Good option if you prefer an open-source solution with more database flexibility and developer-focused features.

Bottom Line

Fastgen excels as a specialized visual backend builder that dramatically reduces development time for APIs, workflows, and database operations. If you're looking to accelerate backend development without sacrificing scalability or functionality, it delivers exceptional value through its intuitive interface and integrated Postgres database capabilities.
