Keel – A schema-driven back end engine with Go and TypeScript
Hi HN, I’m one of the creators of Keel and we're excited (and nervous in equal measures) to be sharing this. We built Keel on two principles: 1. A backend is much more than just a database. A scalable backend platform should be grounded in engineering best practices and come complete with a full suite of services without having to wire 10 SaaS products together 2. A backend should not be an engineering black box and should be designed from day one to support the entire organisation over time and scale. Keel is a schema driven backend engine. Define your data model, api actions, permissions,…
In plain words
Keel is a schema-driven backend engine built with Go and TypeScript that automatically generates production-ready APIs from data model definitions. Developers define their data schemas, API actions, permissions, and jobs, and Keel handles API plumbing, authentication via OIDC/SSO, and standard CRUD operations automatically. It's designed for teams wanting to build scalable backends without integrating multiple separate services, and allows custom logic extensions using TypeScript while keeping the backend transparent and maintainable as the organization grows.

Hi HN, I’m one of the creators of Keel and we're excited (and nervous in equal measures) to be sharing this. We built Keel on two principles: 1. A backend is much more than just a database. A scalable backend platform should be grounded in engineering best practices and come complete with a full suite of services without having to wire 10 SaaS products together 2. A backend should not be an engineering black box and should be designed from day one to support the entire organisation over time and scale. Keel is a schema driven backend engine. Define your data model, api actions, permissions, events and jobs in type-safe schemas and get a production-ready backend. All the API plumbing, auth (OIDC/SSO) and core CRUD is handled automatically and you can extend everything with typescript (the core runtime is Go). Your schema actions and custom code are also instantly transformed into internal tooling UI for your whole org. The Keel platform deploys infrastructure based on your schema’s requirements. You get Postgres, serverless functions, event queues, cron jobs, secret management and multiple environments all wrapped up with OTEL compatible tracing. We’re very early but we’d love to hear any feedback! P.S. The Keel runtime is open source (https://github.com/teamkeel/keel) and can be self hosted. The Keel platform then provides fully managed infrastructure and internal tooling. We’ll be launching a BYOC option soon.
