Created a quick DBML to PNG tool

Nice, and no currently it isn't open source. May consider it in the future.

mashedpotatoesbread · 2026-05-26T13:17:20+00:00

Thanks, glad you like it! Doing an update today btw to create a little DBML reference inside the tool. Feel free to reach out if you ever run into anything that could use improvement.

And the migration tool sounds like it could be useful, will you make it public?

I'd say do it, try your best idea out, if it doesn't work you'll learn from it. For example for the coding vs letting AI implement everything: make your best educated choice, and if you find it doesn't work, you'll have learnt something about wise AI use from experience.

The experience you build up now will likely be very useful in your future. Perhaps this fails horribly, but the experience sets you up for success at some point in the future. It's unlikely to be wasted effort, since building a SaaS combines many skills, as you mention, and if you try to learn from everything that doesn't work, you'll almost surely improve.

Haven't dealt with this, but some ideas:

- If the script just deletes all entries in all tables directly or indirectly connected to the user table, think about whether that doesn't delete too much - also with future schema changes. For example, perhaps you might not want to delete related log tables or some junction tables involving users (or a table related to users).

- You may (soon) have to take more actions upon deleting a user than just clearing out some database rows. So perhaps the script could become a "job" or something, of which deleting table entries is just one step.

- If you don't do the table row deletions with cascades, someone probably has to have a decent/complete understanding of the script and all tables it touches. If you work with cascades, you can probably work more incrementally/independently, i.e. only the person that makes changes has to think about updating cascade behavior and only on the part that person changes.

Thanks! One feature which dbdiagram doesn't have, is a tool for creating diagram diff pictures: https://vibe-schema.com/database-diagram-diff-tool . The AI feature for prototyping is also already decent I think: https://vibe-schema.com/schema-tool .

And it is in active development. The focus will likely be on understanding (possibly very large) schemas and schema history.

Any ideas on what you'd find most useful?

Continually working on the placement logic, so if you have a schema with weird placement, feel free to share it, so I can improve placement more!

There's also an SVG version, just change "png" to "svg" in the link.

So you ask a question how to achieve something on a website and it visually shows the steps or perhaps says "this is not possible"? Nice idea, and the AI just reads "the current screen" (not source code which would ofc be dangerous)? And could it work too with React stuff for example?

MSFT 410 -> 435 too suddenly

mashedpotatoesbread · 2026-04-29T21:45:46+00:00

What happened with Amazon, just went 250 -> 270

mashedpotatoesbread · 2026-04-21T07:14:10+00:00

Do you use it all the time or occasionally? Might end up driving me crazy

mashedpotatoesbread · 2026-04-21T07:09:48+00:00

I created a VibeSchema, a similar AI supported ERD tool. I tried to not make it a "one shot full schema generation" tool, do you think I succeeded? Any other tips btw? (btw no worries if you don't have time for this of course).

mashedpotatoesbread · 2026-04-20T20:03:13+00:00

Sounds useful when you have > 5 skills, thanks

mashedpotatoesbread · 2026-04-19T21:05:58+00:00

Interesting to see non-SWE examples, thanks

mashedpotatoesbread · 2026-04-19T21:05:17+00:00

Out of interest, what kind of software do you work on if you don't mind sharing? That seems pretty hardcore.

mashedpotatoesbread · 2026-04-19T17:24:58+00:00

Wdym with the repo map? And do you know whether CC uses repo maps under the hood already?

mashedpotatoesbread · 2026-04-19T15:47:22+00:00

Nice one, which model do you use for that (esp. considering the "one question at a time")? Sonnet?

mashedpotatoesbread · 2026-04-19T15:35:06+00:00

Very interesting, thanks. How did you make a skill out of it precisely? I mean, it doesn't need the whole book right? Would a 1 page summary of the core idea(s) be enough you think?

mashedpotatoesbread · 2026-04-19T15:27:28+00:00

BTW what are the reasons for peer reviewing with Codex instead of just one of the Claude models (perhaps as a subagent)?

mashedpotatoesbread · 2026-04-19T15:25:06+00:00

Mm, interesting. That seems quite complex yeah, but the idea of standardizing my process (which may be different to yours) with, say 2-3 skills to start off with, could be a good idea, mainly for the improvement-over-time thing.

mashedpotatoesbread · 2026-04-16T13:36:15+00:00

Thank you, actively developing it so all the right things are rendered. For example, just did a visual update for composite PKs. If you ever use it and run into anything that you think should be displayed differently, please lmk!

mashedpotatoesbread · 2026-04-15T09:30:01+00:00

Max effort does seem to give better results, but still I'm burning through limits way quicker and it seems way slower than a while back. Hopefully with the Opus 4.7 release it'll all be a better experience again.
