Realistic, relational Postgres test data — generated from your schema alone. No production access, no PII risk, no fragile seed scripts. Point Seedfast at your database, describe the scenario, and get a fully populated DB in one CLI command.

The wall

Every team with a real Postgres schema eventually hits the same wall: you need a populated database to develop, test, and demo — but you can't use production data. Either it's regulated (PII, PCI, HIPAA), or the company doesn't exist yet, or your distributed team isn't cleared to touch it.

The existing options are all bad:

  • Anonymization tools start at $200K/year and take weeks to set up
  • Seed scripts are fragile, break on every migration, and fill up with test@test.com
  • Faker / Mockaroo have no foreign key awareness — falls apart past 10 related tables

The third option

Seedfast: realistic, relational data generated from your schema alone, no production access required.

Point Seedfast at your live Postgres, give it a natural-language scope (for example, "fintech app with 100 accounts, transactions, and varied balances"), and it fills your database in one CLI command. Foreign keys resolve automatically. Values are domain-appropriate — names look like names, transactions look like transactions, dates make sense. The same tool works for 10 rows in a unit test and hundreds of thousands in a load test.

Because nothing ever connects to production, there's no PII pipeline to maintain, no security review to clear, no compliance risk to mitigate. The compliance problem doesn't exist instead of being solved.

Who it's for

Teams that can't use production data:

  • Regulated industries — fintech, healthcare, anyone under GDPR / HIPAA / SOC 2
  • Early-stage teams without production data yet
  • Distributed teams where not every engineer is cleared for prod
  • Engineering teams of 5–50 — too small for enterprise TDM, too complex for hand-written seed scripts

Also a strong fit for any team with 20+ tables and a seed file that's quietly become tech debt nobody wants to own.

Postgres-first CLI, runs anywhere you can run a binary.

Questions & Answers

As answered by people managing Codédex and Seedfast.

What makes your product unique?

Seedfast's answer:

Seedfast is schema-driven by design. Point it at your Postgres database and it generates realistic, relational data — written directly into your live tables, with triggers firing correctly, constraints staying valid, and foreign keys resolved across the entire database. Complex schema features (views, JSON fields, enums, deep multi-level relations) are handled natively. One CLI command. No production access required, no seed scripts to maintain, no PII risk.

Why should a person choose your product over its competitors?

Seedfast's answer:

Simplicity. One CLI command, no config files, no dashboards, nothing to maintain. Connect your database, describe what you need in plain English, and the data lands in your tables — usually under two minutes from install to a seeded database. Same command whether you need 10 rows for a unit test or 500,000 for a load testing.

How would you describe the primary audience of your product?

Seedfast's answer:

Developers in compliance-regulated environments who can't use production data, and anyone tired of writing and maintaining seed scripts. The common thread: they want realistic, relational data without the setup tax.

What's the story behind your product?

Seedfast's answer:

We were tired of maintaining seed scripts. Every migration broke them, the data looked fake, and we were burning hours every week on something that should've been a non-problem.

Codédex mentions (5)

  • Looking for a bit of coding advice!
    I'm a new coder too. What helps me is finding a good place to learn the most basic principles and having 2-5 things I want to do. I started with codedex.io , learning Python and HTML and then took their courses and moved on looking for projects with tutorials. Little steps one by one. The rest is practice breaking things down into tiny steps. Source: over 3 years ago
  • self learning towards a web dev career
    I think you should focus on HTML, CSS, and JS, starting with HTML. I just started HTML on a website called codedex.io. Pretty cool so far but I feel like I'm getting into a brand new thing haha. Source: over 3 years ago
  • A beginner in python
    I've been learning Python on a website called codedex.io for about 6 months. It's been great for me so far. I just started on Classes and Objects. Give them a try, you might like them. Source: over 3 years ago
  • Question
    Python is a great language to start as a beginner! I don't know how new you are but a good place to learn some basics is codedex.io (also where I started from zero, 6 months ago haha). Source: over 3 years ago
  • Is it possible to learn Programming and coding? not a tech graduate.
    You should start from the basics with a platform like codedex.io they do Python! It was straightforward to use for me (I'm 32). Give them a try. I am still a beginner, but I was starting from zero. Source: over 3 years ago
