24 alternatives to Daf·thunk – open-source Editor for Prototyping Workflows on Cloudflare

Over the past few months, a student and I set out to explore the impact of vibe coding on web development. Somewhere along the way, we ended up building Daf·thunk, a visual workflow editor. It leverages Cloudflare’s fantastic infrastructure (Workers, D1, KV, Workflows, AI, etc.) to create surprisingly robust workflows that can be triggered manually, via HTTP requests, by email, or on a schedule. During development, we primarily used Cursor with its agent and tab modes, alongside Claude Sonnet 3.5, 3.7, 4, and Gemini 2.5 Pro. Occasionally, we switched to MAX Mode when working on or reviewing…

   Turn any workflow diagram into compilable, running and stateful code▲109

   Hi HN folks, I'm a co-creator of the Dapr CNCF project and co-founder of Diagrid. Today we announced a free-to-use web app that takes any form of workflow diagram (UML, BPMN, scribble in your favorite drawing tool or even on paper) and generates code that runs in any IDE and that can be deployed to Kubernetes and other container based systems, based on Dapr's durable execution workflow engine. This essentially allows you to run durable workflows in minutes and leaves out the guesswork for how to structure, code and optimize a code-first workflow app. I'm happy for you to give this a try and…

   Haystack – an IDE for exploring and editing code on an infinite canvas▲546

   Hi HN, we’re building Haystack Editor (https://haystackeditor.com/), a canvas-based IDE that automates the boring stuff (plumbing, refactoring, and finding code) so that you can focus on the exciting parts of software development! You can see a quick overview of Haystack at https://www.youtube.com/watch?v=c2uZnR5D_cc! (It's currently only on Mac OS but we're working on Linux and Windows. Edit: just added a Linux download!) Haystack was born out of our frustrations with working in large and mature codebases, specifically with navigating and editing functional…

   An open-source, collaborative, WYSIWYG Markdown editor▲460

   Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…

   Just Fucking Use Cloudflare – A satirical guide to the CF stack▲33

   Inspired by the recent justfuckingusetailwind.com, I built a similar "love letter" to the Cloudflare ecosystem. I find myself reaching for Workers, R2, D1, and KV for almost every project lately, so I wanted to capture that sentiment in a single, slightly over-the-top page. It’s a simple side project, but the stack is: - Vite + TypeScript - Biome + Ultracite - Deployed (obviously) on Cloudflare First draft in Claude, the copy was drafted with Grok to get that specific tone, then I used Google's AI Studio to accelerate the build with touch up's in Cursor. Link:…

   DAGForge▲8

   Built DAGForge to make generating and validating Airflow DAGs much faster. Most AI tools produce broken or incomplete DAGs, so I added: Airflow-aware validation (operators, imports, params) Syntax + security checks Deterministic JSON parsing to avoid hallucinations Support for local or cloud LLMs Would love feedback from data engineers and Airflow users.

    Windsurf – Agentic IDE▲101

    At Codeium, we've been building AI-powered extensions for a while (we first launched our VSCode extension with autocomplete a little over 2 years ago!), but we've always thought there would come a day where we would hit the limits of what could be achieved within existing IDEs, so we decided to build our own: Windsurf (yes, it's yet another VSCode fork :) We've stuffed a lot of cool features into Windsurf—a super fast autocomplete model, an inline diff generation experience that feels truly native, but we're most proud of Cascade, which is an evolution of the sidebar chat experience that…

    DAC – open-source dashboard as code tool for agents and humans▲119

    Hi all, this is Burak. When agents became a reality one of the first things I wanted to do was to automate building dashboards. The first, and the most obvious, wall that I ran into was that a lot of the tools were just driven by UI. This meant that without the agents handling browser UIs and whatnot, it wasn't possible to have the agents do that. In addition, it would be impossible to review any of the changes the agent would make. The first instinct there is to get your agent to build a React app for the dashboard. This works beautifully for the happy path, but I quickly ran into other…

    Davia – Open source visual, editable wiki from your codebase▲47

    Hi HN, We’re Ruben, Afnan, and Theo, and we’re building Davia to solve a common problem: documenting and explaining large codebases is complex. It takes too long to generate even a first draft of a wiki, visuals are essential to understand the structure, internal docs should be editable in the IDE, and most solutions aren’t open. Davia is an open source tool. You enter the path of your repo, and it generates a visual wiki you can explore and edit. Diagrams are created automatically, and you can update everything either in your IDE or in a Notion-like editor. The project is still early, and…

New in V4: Next.js: Lowdefy now runs on top of the Next.js framework. All of Auth.js: App auth is now handled by Auth.js supported providers, adapters and callbacks and events, easy to configure, but all of which can be customized.

    Daffodil – Open-Source Ecommerce Framework to connect to any platform▲66

    Hello everyone! I’ve been building an Open Source Ecommerce framework for Angular called Daffodil. I think Daffodil is really cool because it allows you to connect to any arbitrary ecommerce platform. I’ve been hacking away at it slowly (for 7 years now) as I’ve had time and it's finally feeling “ready”. I would love feedback from anyone who’s spent any time in ecommerce (especially as a frontend developer). For those who are not javascript ecosystem devs, here’s a demo of the concept: https://demo.daff.io/ For those who are familiar with Angular, you can just run the…

    Hi HN, we’re Nick and Drew, and we’re building boxes.dev – the first cloud-only agentic dev environment (ADE) that gives every Codex and Claude Code agent its own cloud computer. We’re two engineers who previously built Gem (co-founder/CTO and first hire), and we spent the last year coding almost exclusively using Codex and Claude Code. It’s been a huge change to how we code, and it’s been exhilarating seeing the models keep getting better – but we eventually realized that developing on localhost was holding us back: - Git worktrees are clunky to set up and use for parallelizing work -…

    Open-source app builder for comfy workflows▲59

    Hey, we’ve been working on an open-source project built on top of Comfy for the last few weeks. It is still very much a work in progress, but I think it is at a place where it could start to be useful. The idea is that you can turn a workflow into a web app with an easy-to-use UI. Currently, it should work with any workflows that take images and text as input and return images. We are aiming to add video support over the next few days. Feedback and contributions are more than welcome!
