Fastgen is a low-code visual API and workflow builder designed for developers and automation specialists to quickly create scalable backends, REST endpoints, and automated workflows. It supports seamless integration with Postgres databases, third-party services, and custom code in JavaScript or Python. Featuring asynchronous workflows, event-driven triggers, debugging tools, and AI-assisted SQL generation, Fastgen simplifies backend development, task automation, and data synchronization for web and mobile applications.

Fastgen brings impressive flexibility to low-code backend development, letting you visually build APIs and automate workflows while injecting custom JavaScript or Python for those moments when no-code just isn’t enough. Its event-driven, asynchronous workflow engine is a standout for tasks like syncing data between services or orchestrating complex automations without worrying about API timeouts or infrastructure headaches. Fastgen’s seamless package management and secure API token authentication feel refreshingly modern.

However, some rough edges remain. The lack of TypeScript support, incomplete control flow features, and workflow encapsulation quirks may frustrate experienced developers. Fastgen is best suited for teams automating business processes, building integrations, or rapidly prototyping APIs. If you can work within its current boundaries, it’s a powerful tool worth exploring carefully.
