So thrilled to announce we've released Instant SQL! It's a new interaction pattern for writing SQL queries that provides realtime result previews and deep query inspection & debugging. Bye bye run button 👋 Truly, literally only possible with DuckDB

Obsidian. It’s perfect for it.

Big QOL improvements to our AI UI features! We moved our schema-aware cmd+k inline prompt tool out of preview. I figured most people would use it to just edit single expressions, but it's turning out to be a great way to jump-start queries! paired with instant sql == 🤯

Who has "figured out" / is solving the code review problem with AI agents? (asking people who actually ship stable, production-grade software to paying customers)

Largely my experience to date. My team is working on both streamlining code review and making it easier to detect / course correct if something goes wrong. The code the models are trained on won’t get you the code you need in this new paradigm

main reason why SQL tooling is bad imo

If context engineering is the new hotness for engineering, context management is the new UI hotness/challenge for designers.

What are people doing for fast, local-first search in web apps these days?

I could see a pretty sick feature of Claude Code or Cursor being some kind of annotated walkthrough of a branch that explains it. I'm writing hybrid plans for both humans & AI right now, and we're interleaving code examples with prose literate programming has a bright future!

using Claude Code to plan features I've been thinking about for months but haven't gotten around to designing. We collaborate on the big, ambitious version then carve out the v1 These become 2 md files. Will see if having it read both before implementing v1 is useful

new hack is to tell claude code to put a tldr at the end, not benefits or whatever nonsense I don't care about

📢 DuckLake 0.2 is out! We added new features to the specification and improved support in the DuckDB ducklake extension. See the announcement blog post at duckdb.org/2025/07/04/duc….

Looking for a good SF based in-person browser tech focusedm meetup to talk about how we push the browser to the limit at MotherDuck. Any ideas?

the problem with spawning subagents to review a detailed plan is that they're also idiots, just like the idiot I generated the plan with in the first place

Totally game-changing. I’m so excited for DuckLake. We patched in time travel support for Instant SQL so you can easily explore any snapshot of data!

Another Tuesday, another successful pair coding session w/ Claude Code and teammates. Last week’s session gets shipped next week, but it’s basically done. This week’s will turn out similarly We’re accelerating whole parts of the UI roadmap each week while I multitrack other work

Thrasher style Instant SQL hat just dropped

so cool! I tried to implement this in canvas for web editors while on parental leave. Was not upset with the result

going on vacation soon. will probably get to finally building the dataviz system of my dreams

Does anyone have a good resource on effective local RAG? I'm thinking about how to set up obsidian to be more easily searchable.

I just tried this, and wow does it make a difference when I ask Claude Code to give me status updates, PR messages, code comments, etc.!
