The wall

Every team with a real Postgres schema eventually hits the same wall: you need a populated database to develop, test, and demo โ€” 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 โ€” 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 โ€” 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 โ€” 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 5โ€“50 โ€” 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.

Possible disadvantages of AZIPCODE

  • Limited Advanced Features
    Compared to more robust location data platforms, AZIPCODE may lack advanced features such as radius searches, bulk lookups, or detailed demographic breakdowns that power users or businesses might need.
  • Ad-Supported Experience
    As a free tool, the website may display advertisements that can be distracting and detract from the overall user experience during ZIP code searches.
  • Limited API Access
    The site may not offer a well-documented or robust API for developers who want to integrate ZIP code data into their own applications or services programmatically.
  • U.S.-Only Coverage
    AZIPCODE focuses exclusively on U.S. ZIP codes, which limits its usefulness for users who need postal code information for international locations.
  • Data Freshness Concerns
    It may not always be clear how frequently the ZIP code data is updated, raising potential concerns about the accuracy and currency of the information provided, especially for newly created or modified ZIP codes.

Questions & Answers

As answered by people managing Seedfast and AZIPCODE.

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 โ€” 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 โ€” 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.
