While FluentDynamoDB remains in a hackathon code freeze, we thought we'd bring a small early holiday gift to the community by open-sourcing some internal tooling we've already built for our SaaS platform.

Introducing LambdaOpenApi.​

Today, we're releasing one of those utilities: LambdaOpenApi.

LambdaOpenApi is a Roslyn source generator that produces compile-time OpenAPI documentation for AWS Lambda applications built with the Lambda Annotations framework. It eliminates the manual drift-prone OpenAPI step and ensures your contracts stay accurate, fast, and cost-free to generate.

We originally built this for our own SaaS platform work, but it quickly became clear it could help other teams working with Lambda Annotations.

If you're interested in improving your Lambda Annotations workflow, or you want API documentation handled automatically, check it out here:

👉 GitHub: https://github.com/Oproto/lambda-openapi

👉 NuGet: Oproto.Lambda.OpenApi

This is just one of several internal tools we plan to release. Even while the main FluentDynamoDB repo remains frozen, the ecosystem continues to grow, and we're looking forward to sharing more soon.

More to come.
