24 alternatives to 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…

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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. I made a tool to visualize MySQL EXPLAIN query plans launched in 2024; newer entries below may have overtaken it.

    My 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…

    This is like 4 years old, but I’m braver now and ready to share stuff with this community. I’ve been a lurker for a while. I made this tool - it’s kind of like “explain” but it tells you about what locks would be required by the query. 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.

    I have been working on SQL Explorer, an open source, Django-based reporting and query tool for (gulp!) almost ten years. It's a tool that fits just right for me and many others, and I love and use almost every day. Write SQL, share results, do some analysis, get insight. No surprises. A live demo instance is here (no login or anything required): https://demo.sqlexplorer.io/ And here's a fairly unprofessional, but very enthusiastic, video tour: https://sql-explorer.s3.amazonaws.com/Sql+Explorer+5.mp4 The UI is constrained enough that there's very little to learn,…

    Hi HN! I've found this visualization tool immensely helpful over the years for getting an intuition for how an LLM "sees" some piece of text, and with a bit of elbow grease decided to move all compute to client side so I could make it publicly available. I've found it particularly useful for - Understanding exactly how repetition and patterns affect a small LM's ability to predict correctly - Understanding different tokenization patterns and how it affects model output - Getting a general sense of how "hard" different prediction tasks are for GPT-style models Known problems (that I probably…

    One year ago I open-sourced my very first 'real' project and shared it here. I was a college student in my senior year and desperately looking for a job. At the time of sharing it i couldn't even afford a domain and naively let someone buy the one i had my eyes on lol. It's been a hell of a year with this blowing up, me moving to another country, and switching 2 jobs. In a year we somehow managed to hit 26k stars, grow a 1000+ person discord community, and support 37 languages. I couldn't be more grateful for the community that helped this grow, but now i don't know what direction to take…

    Hey! I'm Andrei. I got frustrated by how people tend to build overcomplicated backend systems, being "motivated" by big tech case studies and popular books. So, I started exploring lean architecture, and building my digital garden of ideas, approaches and data that align with this direction. Here I want to present one of the tools – Sizing tool for PostgreSQL. I've benchmarked PostgreSQL on different EC2 instances and disks, with different initial data sets to see performance that these instances can give you. And I've built a tool to visualize this data, which I welcome you to explore. So,…
