When I first heard about pgMustard, I dismissed it as “yet another PostgreSQL explain visualizer”. Why would I want to pay for one, when there are free ones out there? My opinion immediately changed when I first tried it, though. The visualizations are not only more readable than others, pgMustard also does an amazing job of pointing out the problematic parts of the analyzed query. On top of that, it provides clear explanations on what happened in that part of the query, why it is a problem, and what I can try to fix it. This is above and beyond what any other tool I’ve tried provides. It’s very actionable and speeds up my troubleshooting and fixing process my a lot.

The breakdown and prioritization by estimated time-saving potential is great. We run a multi-service application with several PostgreSQL databases, and as our data has grown, query performance has become more important. As a non-expert in DB optimization, pgMustard has done a great job boiling down the large amount of info Postgres gives you into genuinely useful visualizations. The smart filtering that collapses fast operations helps a lot—our queries often involve multiple joins across tables, and the tool surfaces what's actually slow. The built-in explanations have also taught the team about PostgreSQL internals, which helps us write smart SQL going forward.

The UI is friendly and easy to use. Plus, they're constantly keeping it up to date with new Postgres versions and making improvements to the product. The customer support is brilliant - super responsive and helpful.
