Ducktape – a tiny HTTP/2 wrapper around DuckDB's Appender API
Hi HN! I’m an engineer at Artie where we do real-time data replication. We were adding MotherDuck as a destination and the first version just used DuckDB’s Go driver directly. It worked great on my machine… until we wired it into our Transfer service (https://github.com/artie-labs/transfer). Because the driver requires CGO, our cross-compiles to amd64 and arm64 started failing, we lost our easy static binaries, and our Docker images had to pull in C toolchains and system libraries just to support one dependency. We tried isolating the CGO bits in a separate module, but it…
Ducktape – a tiny HTTP/2 wrapper around DuckDB's Appender API launched on December 16, 2025 with 12 votes, #747 of 11,628 launches that month and more than 75% of that year's launches.
In plain words
Ducktape is a lightweight HTTP/2 wrapper around DuckDB's Appender API that enables data streaming without requiring C bindings. Built for engineers using DuckDB's Go driver who face cross-compilation and dependency issues, it wraps DuckDB as a standalone microservice that accepts NDJSON data over HTTP/2 streams. This eliminates CGO requirements, allows static binary builds, and reduces container complexity.

- DUDuck-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…
- MAMotherDuck – a serverless data analytics platform powered by DuckDB2023 · ▲17
Hi folks.. Co-founder and Head of Produck at MotherDuck. We're building a new type of analytics data platform based on an exciting open source project DuckDB! We just launched today, so please head over to our website and request an invite[0]! When we first started MotherDuck a little over a year ago, we realized that the modern data platforms like BigQuery and Snowflake are of exceptional quality. They're also very mature, packing diverse set of features across a variety of use cases. So it doesn't seem like a good idea to go and compete with them... But then we found DuckDB. DuckDB changes…

MyDuck Server – Supercharge MySQL and Postgres Analytics with DuckDB2024 · github.com · ▲32Hello HN! We're excited to announce MyDuck Server, an open-source project that seamlessly integrates the analytical power of DuckDB with your existing MySQL & Postgres databases. *Backstory* Currently, there are no fully satisfactory open-source OLAP solutions for MySQL & Postgres. In the MySQL ecosystem, HeatWave offers close integration, but it's a proprietary, commercial product from Oracle. The Postgres community has seen promising DuckDB-based extensions emerge, including the official pg_duckdb. However, extensions can introduce isolation concerns in mission-critical environments.…

Talanoa▲346Hi 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…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
