Alternatives
Products that do what ZenStack – DSL to define data and access rules closer to the database does
We're excited to announce the launch of ZenStack V1 after a year of refinement. With ZenStack, we introduce ZModel, a domain-specific language (DSL) that simplifies the definition of data and access rules, bringing it closer to the database level. This eliminates the need for extensive, repetitive coding on the application side. We would love to hear your feedback and opinions on it. Thank you!

Half a year ago, we posed a Show HN about ZenStack V1 as "DSL to define data and access rules closer to the database" Throughout the month, we've attracted quite a few early adopters. Some of them, such as MermaidChart, have successfully launched into production. After talking with them, we realized that many individuals found ZenStack while seeking a cleaner and easier alternative to RLS. As a result, we pivot ourselves to be a “TypeScript toolkit on top of Prisma ORM with a fine-grained Authorization layer, auto-generated type-safe APIs, and frontend hooks”. In V2, besides the more…

Hi HN, I'm Jiasheng, co-creator of ZenStack. Access control usually ends up scattered across app code instead of living with the data model — and that's riskier when the code is written by an agent, since it's easy to ship a query with a missing or incomplete authorization check. ZenStack enforces policy (RBAC/ABAC/relation-based) directly at the ORM layer, on top of Kysely, so every query gets checked the same way regardless of who wrote it and who is calling it. Postgres RLS is an option too, but it's hard to maintain and scale, and it's Postgres-only — ZenStack's approach is…

We have been polishing ZenStack for the past few months with the community. As it has been successfully used in production by some of our users, we think it’s time to share our beta with you. ZenStack is built on top of Primsa ORM, extending it with a powerful access control layer that simplifies the development of a web app's backend. By defining authorization policies and validation rules right inside the data schema, your database client can automatically enforce these constraints at runtime. Why we built this: Based on our experience developing several commercial SaaS products, we have…

Dear HN, I am Riwaj, the cofounder of dstack.ai (https://github.com/dstackai). A few months ago, we built an online service that allows users to publish data visualizations from Python or R. The idea was to build a tool that did not require additional programming or front-end development for publishing data visualizations. Such a code can be invoked from either Jupyter notebook, RMarkdown, Python, or R scripts. Once the data is pushed, it can be accessed via a browser. Open-sourcing dstack: During our customer discovery phase, we realized that dstack.ai should integrate a lot…

Hey HN! Wasp (https://wasp-lang.dev/) is a simple config language (DSL) and framework for building full-stack web apps. You describe the high-level features you want (auth, CRUD, async jobs, …) using the Wasp DSL, and write the rest of your logic in React, Node.js, and Prisma. We’re focused on simplifying developer experience and ensuring best practices. Everything is open source. Why another full-stack framework? And why a config language/DSL? We were still experiencing a lot of boilerplate (repetitive tasks) using other frameworks—things like duplicating data models…

Hi everyone, I've made an open-source library for using design by contract (DbC) principles in the Zig programming language. It's called Zig-DbC, and it currently provides the following features: - A simple API to define preconditions, postconditions, and invariants. - Contracts are active in `Debug`, `ReleaseSafe`, and `ReleaseSmall` modes to catch bugs early. - All checks are removed at compile time in `ReleaseFast` mode for zero performance cost. - An optional mode to handle partial state changes in functions that return errors. - Transparent error handling that propagates errors from…

We launched ZenStack V2(https://news.ycombinator.com/item?id=40205699) one year ago. It is built on Prisma, adding advanced features like access control, polymorphism, API/Hook generation, etc. But as we added more features, we felt more constrained by our foundation, Prisma(Check out the specific constraints here https://zenstack.dev/blog/next-chapter-1). Therefore, we made a bold decision for ZenStack V3 to reimplement the ORM part from scratch, keeping full compatibility with the Prisma schema and API. As a result, you could get the best of both…

I had already posted the project a couple of years ago, and it gained some interest, but a lot of stuff has been done since then, especially regarding performance, a completely new JSON store, a REST API, various internals refactored, an improved JSONiq based query engine allowing updates, implementing set-oriented join optimizations, a now already dated web UI, a new Kotlin based CLI, a Python and TypeScript client to ease the use of Sirix... First prototypes from a precursor stem already from 2005. So, what is it all about? The system uses ideas from ZFS (a keyed index trie, storing…

Hi HN, My team and I are building Tabstack to handle the "web layer" for AI agents. Launch Post: https://tabstack.ai/blog/intro-browsing-infrastructure-ai-ag... Maintaining a complex infrastructure stack for web browsing is one of the biggest bottlenecks in building reliable agents. You start with a simple fetch, but quickly end up managing a complex stack of proxies, handling client-side hydration, and debugging brittle selectors. and writing custom parsing logic for every site. Tabstack is an API that abstracts that infrastructure. You send a URL and an intent; we…

Google Zanzibar datalog lang lets you describe concepts and express how they are related. I generalize it to DSL you can use on Lean4 (and other languages) this lets you represent a knowledge base you can construct, store and evaluate, have it under git and improve without big engines or relaying on external infrastructure.

Hello HN, I am Sonal, a data consultant from India. For the past few months(and years!), I have been working on an entity resolution tool to build a single source of truth for customers, suppliers, products and parts. Here is a short demo of Zingg in action https://www.youtube.com/watch?v=zOabyZxN9b0 As a data consultant, I often struggled to build unified views of core entities on the datalake and the warehouse. Data spread across different systems has variations and consistencies making Customer 360, KYC, AML, segmentation, personalization and other analytics difficult. As I…

Hey HN – Stefan and Elijah here from DAGWorks (http://dagworks.io/, YC W23). If you don’t remember us from our previous HN launch (https://news.ycombinator.com/item?id=35056903), we’re the authors of Hamilton (https://github.com/dagworks-inc/hamilton), an open-source library for building self-documenting, modular dataflows in python that works for data, ML, LLM pipelines, & even web-workflows. We’ve been developing this UI for a while and we’re excited to say we open-sourced it! It comes out of the box with the following capabilities, and…

Hi HN, I'm Dan Draper, founder of CipherStash. We've spent 5 years building per-value searchable encryption tech. We realized that encryption like this is incredibly powerful but the engineering required is generally not worth the effort. So we built a platform and opensource SDK to take the cry out of cryptography :) CipherStash Stack is: * A searchable encryption SDK for TS and Postgres * Fast, key management with Zerokms (backed by HSM) * A transparent SQL proxy * Auth library and OIDC federation service * Skills for data security Integrations include Prisma Next, Drizzle, Auth0, Clerk…
