Dummy Database is built to solve a simple, yet annoying problem — generating realistic test datasets quickly, without writing scripts or juggling Excel files.
It’s designed for: - Developers needing dummy databases for prototyping & testing. - Analysts and BI specialists preparing demo dashboards. - QA engineers creating data scenarios for testing. - SQL learners who want practice datasets on demand.
What makes it special? - Create from simple tables to full relational databases with PK/FK. - 35+ data types including Numbers, Dates, Names, Booleans, etc. - Unique Event Sequences — simulate user actions and workflows. - Advanced data controls — outliers, nulls, repeats, distributions. - ERD visualization to map relationships. - Built-in PostgreSQL editor to query generated data. - Export as CSV, XLSX, SQL DDL, or full ZIP. - Free up to 10,000 records per table for registered users — no paywalls or limits.

DUMMY DATABASE's answer
A free, all-in-one data generation platform that builds everything from simple tables to full relational databases with advanced controls, unique event sequences, ERD visualization, built-in SQL querying, and multiple export formats — no limits, no paywalls.
DUMMY DATABASE's answer
Unlike other data generators, DUMMY DATABASE gives you full relational database creation, unique event simulations, advanced control over every field, built-in SQL querying, and generous free limits — so you can go from idea to test-ready data without restrictions, subscriptions, or hidden fees

Official references like OpenSCAD help when your generation target is code-based, because you can often parse, render, and inspect outputs deterministically. That is much safer than evaluating only by screenshot quality. - Source: dev.to / 3 months ago

Love OBS and Blender. Recently started using Kdenlive and it is awesome. Big fan of OpenSCAD[1] and solvespace[2] for making functional 3D prints. I'm going to branch out a bit here and say GrapheneOS is my favorite thing going on right now. [1] https://openscad.org/ [2] https://solvespace.com/index.pl. - Source: Hacker News / 5 months ago
BTW, if you want to design some models for 3D printing but the only thing you know to do is to code, you can use OpenSCAD & program the obejcrs into existence: https://openscad.org/ Also recommend using the BOSL2 library with OpenSCAD - it turnes an already very powerful tool into something insane: https://github.com/BelfrySCAD/BOSL2. - Source: Hacker News / 8 months ago
There is also Joyce's Java Version of Euclid's Elements: https://mathcs.clarku.edu/~djoyce/java/elements/elements.html and I'm still impressed by the custom Unity tools which Freya Holmér uses for her videos: https://www.youtube.com/watch?v=jvPPXbo87ds Wish Geogebra was both more capable and widely used: https://www.geogebra.org/ That said, these days if I need to plot out something I just use OpenSCAD:... - Source: Hacker News / over 1 year ago
