A brief overview: 1. Workflows steps share a running context, with access to data they need require. 2. Steps in the workflow (builders) are chained together based on a topologically sorted built from the predefined input & output. 3. No servers spin up (like Conductor/Cadence) - the orchestrator is low level and meant for simplifying business logic. 4. Before/After listeners for each step. Would love to hear your thoughts and feedback!

A lightweight engine for durable execution / deterministic workflows I built with Rust, wasmtime and the WASM Component Model. Its main use is running reliable, long-running workflows that can automatically resume after failures. Looking for feedback on the approach and potential use cases!

We'd love to share our work with you: Restate, a system for workflows-as-code (durable execution). With SDKs in JS/Java/Kotlin and a lightweight runtime built in Rust/Tokio. https://github.com/restatedev/ https://restate.dev/ It is free and open, SDKs are MIT-licensed, runtime permissive BSL (basically just the minimal Amazon defense). We worked on that for a bit over a year. A few points I think are worth mentioning: - Restate's runtime is a single binary, self-contained, no dependencies aside from a durable disk. It contains basically a…

It all started with a conversation among friends about limitations in current multi-agent orchestration frameworks. We faced issues like limited control over agent memory and state, complicated persistence, scaling problems, and lack of type safety in Python-based tools. These challenges inspired us to try something different. The result was GraphFlow, a Rust-based lean framework for orchestrating multi-agent workflows that's simple, scalable, and robust. Its key features include: Graph-based orchestration: Easily define workflows using nodes and edges. Lean Execution Engine: A minimal and…

Hi HN — I’m learning Rust and decided to build a universal CLI for running code in many languages. The tool, Run, aims to be a single, minimal dependency utility for: running one-off snippets (from CLI flags), running files, reading and executing piped stdin, and providing language-specific REPLs that you can switch between interactively. I designed it to support both interpreted languages (Python, JS, Ruby, etc.) and compiled languages (Rust, Go, C/C++). It detects languages from flags or file extensions, can compile temporary files for compiled languages, and exposes a unified REPL…

Servicer is a CLI to create and manage services on systemd. I have used pm2 in production and find it easy to use. However a lot of its functionality is specific to node.js, and I would prefer not to run my rust server as a fork of a node process. Systemd on the other hand has most of the things I need, but I found it cumbersome to use. There are a bunch of different commands and configurations- the .service file, systemctl to view status, journald to view logs which make systemd more complex to setup. I had to google for the a template and commands every time. Servicer abstracts this setup…

Hi HN! We’re Asankhaya and Rohan and we are building Patchwork. Patchwork tackles development gruntwork—like reviews, docs, linting, and security fixes—through customizable, code-first 'patchflows' using LLMs and modular code management steps, all in Python. Here's a quick overview video: https://youtu.be/MLyn6B3bFMU From our time building DevSecOps tools, we experienced first-hand the frustrations our users faced as they built complex delivery pipelines. Almost a third of developer time is spent on code management tasks[1], yet backlogs remain. Patchwork lets you combine…

I’m sure many of you are familiar, but there’s a treacherous gap between finding (or building) a model that works in PyTorch, and getting that deployed into your application, especially in consumer-facing applications. I’ve been very interested in solving this problem with a great developer experience. Over time, I gradually realized that the highest-impact thing to have was a way to go from existing Python code to a self-contained native binary—in other words, a Python compiler. I was already pretty familiar with a successful attempt: when Apple introduced armv8 on the iPhone 5s, they…

Opsflow cofounder here! We launched a bunch of things recently, some of them well received (Terragen, AWS Bootstrap). It's no secret that AWS is hard, and our mission is to make it simple. What HN crowd helped us realise is that the UI was still not simple enough. Rather confusing in fact. So in the last couple weeks we have radically simplified it based on your feedback. We have removed the unnecessarily complex concepts like Services and Environments - it's just Apps now. All options are now on the new Settings screen. Instead of Infrastructure and Software deployments there is now a…

Flowctl is a self-service platform that gives users secure access to complex workflows, all in a single binary. These workflows could be anything, granting SSH access to an instance, provisioning infra, or custom business process automation. The executor paradigm in flowctl makes it domain-agnostic. This initial release includes: - SSO with OIDC and RBAC - Execution on remote nodes via SSH (fully agentless) - Approvals - Cron-based scheduling - Flow editor UI - Encrypted credentials and secrets store - Docker and Script executors - Namespaces I built this because I needed a simple tool to…

I've been building Rivers for the past 7 months, an asset-based orchestrator. The core components such as planning, scheduling etc are in Rust and the user facing API is in Python. My most recent release adds OIDC and forward auth support. Security shouldn't be paywalled :)
