I made a tool to visualize MySQL EXPLAIN query plans
I was always confused when trying to optimize a slow MySQL query as the output of the EXPLAIN command is so cryptic and totally useless. And there wasn't any tool that could help visualize what a query does - compared to PostgreSQL which has multiple... So, I started developing such a tool for MySQL. But boy, I didn't expect how complicated this is in reality. There were so many things hiding in tiny information pieces that I had to understand. But it also confirmed me in that a tool should try to understand the EXPLAIN output and not a human as it is too easy to oversee something. After…
I made a tool to visualize MySQL EXPLAIN query plans launched on July 12, 2024 with 19 votes, #1,076 of 5,184 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
This tool visualizes MySQL EXPLAIN query plans in a graphical format to help developers understand and optimize slow database queries. Unlike MySQL's text-based EXPLAIN output, which is difficult to interpret, this tool converts complex query information into visual representations, making it easier to identify performance bottlenecks. It's designed for database developers and engineers who need to troubleshoot query performance without the cryptic command-line output.

Visualize SQL Queries2022 · animatesql.com · ▲259My co-worker and I were debugging a SQL issue; having not seen SQL in two years, I embarrassed myself by confusing union vs. join. After this episode, I tried refreshing my SQL memory, but there are few websites that animate SQL for you. Most of them just have a series of images to help you visualize. There are a few tools that are quite good and robust (especially for large/complex use cases) but require installation and are too complex for my simple purpose. So, just created a small tool to help visualise SQL. Most of the animations are just my understanding of how SQL works. Would…

I was making it as part of a larger tool that would try to prevent deadlocks during migrations at my last company, I never finished it.

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
