24 alternatives to Treenix. Typed runtime for humans and agents

Hello, we're the Treenix team. We're building typed low-code runtime where humans and agents collaborate to build applications and workflows. Write a simple TypeScript class with methods, and Treenix automatically delivers admin interface, storage, API and MCP, access rules, UI form and audit trail. Views in Treenix are reactive, data-bound, and synced across all clients. They also support display contexts: data can render differently depending on the situation — a table in one place, a list in another. You can register multiple Views for the same data type, and the view engine picks the…

    Hi, HN. Gui, Lucis, and the deco.cx team here — we're a bunch of Brazilians building an open-source, all-in-one web editor for the modern TypeScript dev. Check out our GitHub at https://github.com/deco-cx/deco and discover more at our site https://deco.cx/. We built frontend tools at a hyper-growth e-commerce platform for 9 years. Deco.cx is the thing that we wish existed when we were managing hundreds of enterprise-grade React-based websites. The gist is: JSX, HTMX, TypeScript, Tailwind and Deno. All visually editable in a beautiful, collaborative,…

    This started as a hard requirement for my TUI-based editor application, it ended up going in a few different directions. A suite of tools that help with semantic code entities: https://github.com/odvcencio/gts-suite A next-gen version control system called Got: https://github.com/odvcencio/got I think this has some pretty big potential! I think there's many classes of application (particularly legacy architecture) that can benefit from these kinds of analysis tooling. My next post will be about composing all these together, an exciting project I call…

    Hey HN, I'm Anurag, founder and CEO of Render, a cloud for application developers. We've just launched Render Workflows, a way to define durable tasks by decorating plain TypeScript or Python functions and running them on Render without operating queues, worker pools, retry logic, and state management. Code example below [1]. The use cases we have in mind include agent loops, ETL/data pipelines, billing flows, and other long-running jobs. The model is simple: mark an existing function as a Task, deploy the repo as a Workflow, then trigger runs from your application code or via our API.…

    Author here. I really love the programming paradigm behind by Phoenix LiveView applications and wanted to expand the ecosystem to include programmers like myself that love Typescript. In summary, LiveViewJS reuses all the Phoenix client code and implemented a new backend in Typescript to handle client events and send back updates. Lots more detail and examples in the repo. Would love any questions and/or feedback. Thanks!

    I started writing this book 10 years ago in JavaScript, got through a few chapters (asymptotic notation, basic techniques, start of sorting), and then abandoned it. Recently I picked it back up, converted everything to TypeScript, and used AI (Zenflow [1] + Claude Opus 4.6) to complete the remaining chapters. I provided the structure, direction, and initial chapters; the AI generated the bulk of the remaining content under a spec-driven workflow. The book covers roughly a first 1-2 year CS curriculum: sorting, dynamic programming, graph algorithms, trees, heaps, hash tables, and more. All…

    Hi Hacker News! My name is Sagar, I’m working on a startup called Speakeasy - we’re making all APIs self-service. The platform is currently in beta, but we’re independently launching this tool which you can use to generate language-idiomatic, statically-typed TS SDKs from any public OpenAPI schemas. We hope to continue iterating on this to give devs a way to easily generate high fidelity client SDKs for all the major languages. Inspiration for this product is from past experiences struggling with OpenAPI. I was originally optimistic about using the OpenAPI tools to build out our offering,…

    We've been building Crust (https://crustjs.com/), a TypeScript-first, Bun-native CLI framework with zero dependencies. It's been powering our core product internally for a while, and we're now open-sourcing it. The problem we kept running into: existing CLI frameworks in the JS ecosystem are either minimal arg parsers where you wire everything yourself, or heavyweight frameworks with large dependency trees and Node-era assumptions. We wanted something in between. What Crust does differently: - Full type inference from definitions — args and flags are inferred automatically. No…

    Hi HN! I've built [CXXStateTree](https://github.com/ZigRazor/CXXStateTree), a modern C++ header-only library to create hierarchical state machines with clean, intuitive APIs. It supports: - Deeply nested states - Entry/exit handlers - State transitions with guards and actions - Asynchronous transitions with `co_await` (C++20 coroutines) - Optional runtime type identification for flexibility It's ideal for complex control logic, embedded systems, games, robotics, and anywhere you'd use a finite state machine. I’d love feedback, use cases, or contributions from the…

    I've been building a web UI library for a side project of mine. I thought it might be useful to others, so I'm releasing it as open source. To put it simply, I realized that most of my pain points with React come from its declarative model ui=f(state). So I'm trying something that I'm calling "imperative JSX." Instead of treating JSX as the source of truth for your UI, it essentially becomes a query interface for DOM manipulation. I first had the idea for it a few months ago, and only began writing it in earnest last week, so it's extremely early and nowhere near production-ready. Still, I'd…

    Hi HN! We’re excited to share our new code generator that lets you ship high-quality TypeScript SDKs, that your users will love, from your OpenAPI documents. Our ongoing goal is to help you build one SDK that runs anywhere modern JavaScript runs. This includes new runtimes like Deno and Bun in addition to the ever-popular Node.js. Additionally, the popularity of AI has meant server-sent events and file streaming are also commonplace - we wanted to cover these use cases too. This explosion in new runtimes and ways of interacting with APIs shifts cognitive burden on API developers often having…

In combination with WebCodecs, these two technologies lead to unprecedented rendering capabilities on the web and pave the way for the next generation of video processing…
