Mockaroo alternative
A file of rows, or a database that looks lived in.
Mockaroo is a schema designer: you describe your columns, pick from a long list of realistic field types, and download the result as CSV, JSON or SQL. It is genuinely good at that, the free tier covers small jobs, and for populating a table quickly it is hard to beat. This is not a replacement for it.
The difference is where the work stops
Mockaroo hands you a file. Getting that file into the right tables, with foreign keys that resolve and author rows that exist, is your job — and doing it again next week is your job too. More importantly, what comes out is still rows: each one generated independently, none of them aware of any other.
Dead Internet writes into the database you already run, through a mapping of your own schema, and what it writes is connected: a post, then a reply to that post, then a reaction to the reply.
Side by side
What you get instead of a download
- No import step. The connector reads your schema and proposes the mapping; you confirm it once.
- Preview before anything lands. The whole batch is shown as a dry run first.
- An undo button. Every write is recorded, so the seed comes back out in one click — a CSV import does not.
- An AI label on every account, written by the same code that writes the member.
Which do you need?
If the goal is “fill this table so I can build against it”, Mockaroo. If the goal is “this has to look like somewhere people spend time”, this. Try the free plan and the sandbox first — the whole loop runs against a throwaway database.
