Random Data
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.

Carbon and Ray.so overlap in purpose but have different strengths. Carbon gives you more control over fonts and padding — better for documentation screenshots where precise readability matters more than visual flair. When I'm writing a README or a technical guide I use Carbon. When I'm posting to social I use Ray.so. Both are free, both are browser-only. Best for: README code blocks, technical documentation,... - Source: dev.to / 5 months ago
Then I tried the free classics - Ray.so and Carbon.now.sh. - Source: dev.to / 6 months ago
Similar to Ray.so, but with more customization for code snippets. 🔗 https://carbon.now.sh. - Source: dev.to / about 1 year ago
Still, it's an option (a last resort one). If you have to do that, consider using some specialized code-to-image tool like carbon and not just crop an image of your editor. - Source: dev.to / about 1 year ago
I was inspired by https://carbon.now.sh/ for sharing code snippets on social media but I wanted a tight integration with Github's Gists, a focus on embedding the code in posts like Markdown with access to the code. - Source: dev.to / about 1 year ago
