Hi HN — I am the CTO of Rierino (https://rierino.com/platform/core), a low-code backend platform built for developers, not business users. We recently launched our Developer Lite version on AWS Marketplace, and we're offering a free private trial to HN users.

We built our low-code platform while working with scale-ups, out of frustration with how painful and expensive backend logic can be to implement and maintain in high-speed, distributed environments. It either meant hand-coding everything or relying on rigid tools that abstract away too much. We tested a range of LCNC platforms before deciding to build our own, because they either focused on front-end UIs with little support beyond CRUD, couldn’t meet our performance or scaling needs, or were SaaS-only.

What makes Rierino different:

- Not a UI builder, focused on complex, high-performance backend development

- Microservices architecture with full control over what each microservice can execute and access

- Low latency and high performance serving millions of customers with tens of thousands of internal users

- Flexible deployment: run on any public or private cloud, on-premises, and with your preferred configuration and APM stack

- Open architecture integrating with existing systems, including databases, cache, file systems, and IAM solutions

- Supports advanced patterns like event streaming, change data capture (CDC), complex event processing (CEP), and real-time ML scoring

- Built-in AI agent development capabilities with support for MCP, A2A, and WoT for advanced tooling and orchestration

What you can build with the Developer Lite version (in your own AWS environment):

- Create and Orchestrate APIs with branching logic and error handling

- Query, read & write on a database with our visual query builder

- Apply RBAC on individual API endpoints

- Integrate with 3rd party systems using REST, GraphQL, SOAP, and OData

- Extend flows with inline code when needed

We’d love your feedback:

- What kinds of workflows do you think shouldn’t be built with low-code?

- Where do other tools fall short for backend or middleware use cases?

- What would you want to see in something like this?

We’ll hang around in the comments to answer questions and share examples. Thanks for reading!
