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…

In plain words
Daf·thunk is an open-source visual workflow editor built on Cloudflare's infrastructure. It lets users create and manage workflows that can be triggered manually, via HTTP requests, email, or scheduled tasks. The editor integrates with Cloudflare Workers, D1, KV storage, and AI capabilities to build automated processes. It is designed for developers who want to prototype and deploy workflows without extensive backend setup.

Automate the boring stuff, then automate the fun, then automate automating.
Open source, serverless visual workflow automation with AI on Cloudflare. Build AI workflows, web scraping, and data pipelines visually. MIT licensed.
Build workflows visually by connecting artificial intelligence (AI) models, browsers, data pipelines and APIs, then deploy them on Cloudflare's serverless platform. Workflows scale to zero when idle and up with demand, and the entire stack is yours under MIT. No enterprise tier, no fair-code carve-outs, no asterisks. A React Flow workflow builder for creating automation workflows that makes command-line enthusiasts mildly uncomfortable. Build workflow pipelines by connecting nodes visually. No infrastructure setup, no Docker containers. Just workflows that run on Workers. Run workflows on Cloudflare Workflows and Workers, where servers are merely a philosophical concept.

Turn any workflow diagram into compilable, running and stateful code2025 · workflows.diagrid.io · ▲109Hi 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 canvas2024 · haystackeditor.com · ▲546Hi 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…
Just Fucking Use Cloudflare – A satirical guide to the CF stackDec 2025 · justfuckingusecloudflare.com · ▲33Inspired 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.

DAGForgeNov 2025 · dagforge.com · ▲8Built 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.

Kestra - Open-Source Airflow Alternative2022 · github.com · ▲142Hey HN, I'm really proud to share with you my new open source project: Kestra https://github.com/kestra-io/kestra I created a few years ago a successful open source AKHQ project: https://github.com/tchiotludo/akhq (renamed from KafkaHQ) which has been adopted by big companies like Best Buy, Pipedrive, BMW, Decathlon and many more. 2300 stars, 120 contributors, 10M docker downloads, much more than I expected. Now let's talk about Kestra, an infinitely scalable orchestration and scheduling platform for creating, running, scheduling and monitoring…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
