💡 SaaS Idea: DemoSeeder (Realistic Demo Data Generator for SaaS)

Web app that introspects your DB schema (Postgres/MySQL), then generates realistic, relationally-consistent demo datasets by domain template (CRM, e‑commerce, HR). Supports time-series event generation, PII redaction, snapshots/restore, and one-click seeding for demos, sales sandboxes, and staging.

Platform: web

Why it's a good idea?

Overview

DemoSeeder is a web app that connects to a Postgres / MySQL database, reads the schema and fills it with realistic, relationally-consistent demo data (e.g., CRM, e-commerce, HR). Extra features: snapshots, PII-safe redaction, event/time-series generation, one-click reseeding for sales demos & staging.

1. Evidence of the problem in the wild

  • Reddit r/SaaS thread (2024-03, OP asked: “Is there a tool that could help with populating demo data?” – 20+ comments, no clear winner suggested).
  • Reddit r/DevOps (2022) – “open-source tool to seed a development database with real data” – up-voted post, discussion around Snaplet & Mockaroo shortcomings for relational data.
  • Reddit r/Supabase (2024-07) – users lament Snaplet going into maintenance mode and ask for alternatives to fill empty DBs for demos.
