In 2014 I built Mockaroo to solve a simple problem: testing software without realistic data. I didn’t know it would become my life’s work.
Today, we’re taking the next big step: the Fabricate Data Agent from Tonic.ai, now live on our free plan with $10/month in credits: www.tonic.ai/products/fab...

Today a customer provided me with an example invoice and asked if Fabricate could create a few thousand of them. All I needed to do was drop the file into the chat and ask the agent to generate more.

Fabricate's new Data Agent does use our built-in generators underneath the hood, but less than you might think - mainly for tasks like generating diverse locations with accurate postal codes. Interested in trying it? Sign up for the private preview: www.tonic.ai/lp/fabricate...

Fabricate's new data agent is great at generating complex JSON columns - objects, arrays, deep nesting, and foreign keys sprinkled throughout. If fact it's so good that I needed to implement virtual rendering to keep the JSON view snappy. Interested in giving it a try? www.tonic.ai/lp/fabricate...

Yesterday, a customer asked if we could generate synthetic PDFs, DOCX, and EML files in Fabricate. The feature didn't exist.
So we just built it. Overnight.
This is the speed you get when your foundation is a flexible AI agent. No multi-week sprint planning. We're moving fast.

One cool thing about agentic UI is that the agent is also the customer support. Instead of users asking support how to do something in Fabricate, they can now just ask Fabricate itself — it reads its own docs and answers naturally:

Today's Fabricate update adds a Rank generator. Ranking is a useful building block for things like time series, where you use the rank to add rank * time to a fixed start time to ensure that each row produces a subsequent time.
