Duckle

What it does

Duckle is an open-source desktop ETL/ELT studio with a built-in local AI assistant. Build visual pipelines and run them at native DuckDB speed. 329 components, a scheduler, and an MCP server. No cloud, no servers, no lock-in.

Open-source ETL you deploy on your own servers or cloud. Author on a canvas, in Python or in SQL, then run it headless on a schedule in Docker, on EC2 or on Kubernetes. No vendor cloud, no per-row billing.

Duckle is an open-source ETL platform for teams who want their pipelines running on their own infrastructure. Author on a canvas, in Python or in SQL, then ship the same file to your own server or cloud account: duckle-runner serve runs it headless on a schedule, in Docker or on a box you own, with a web console, roles and an audit trail. Every pipeline is one file in git, so it outlives whoever wrote it. It runs on EC2, EKS or a box you own and uses every core you give it, so a bigger instance is a faster pipeline: 96 million rows out of Postgres to Parquet in 39.9s . No vendor cloud, no per-row billing, no lock-in. Files, databases, warehouses, object stores, streaming brokers, SaaS APIs,…from duckle.org

  Open-source, browser-local data exploration using DuckDB-WASM and PRQL2024 · github.com · ▲227

  Hey HN! We’ve built Pretzel, an open-source data exploration and visualization tool that runs fully in the browser and can handle large files (200 MB CSV on my 8gb MacBook air is snappy). It’s also reactive - so if, for example, you change a filter, all the data transform blocks after it re-evaluate automatically. You can try it here: https://pretzelai.github.io/ (static hosted webpage) or see a demo video here: https://www.youtube.com/watch?v=73wNEun_L7w You can play with the demo CSV that’s pre-loaded (GitHub data of text-editor adjacent projects) or upload…

  Duck-UI – Browser-Based SQL IDE for DuckDB2025 · demo.duckui.com · ▲213

  I built Duck-UI, a web-based SQL editor that runs DuckDB entirely in your browser via WebAssembly. No backend required. The Problem: Every time I needed to query csv, parquet, or even to play with SQL, I had to either: (a) spin up a Jupyter notebook (b) use the CLI (c) upload to a hosted service. Friction at every step (TOO MUCH to load a csv or even to test some sql (study)... The Solution: DuckDB's WASM runtime lets us run SQL analysis client-side. Load CSV/JSON/Parquet files from disk or URL, write SQL, get results instantly. Data stays on your machine. What It Does: SQL editor…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
