As answered by people managing DUMMY DATABASE and StackSwap.
DUMMY DATABASE's answer
A free, all-in-one data generation platform that builds everything from simple tables to full relational databases with advanced controls, unique event sequences, ERD visualization, built-in SQL querying, and multiple export formats — no limits, no paywalls.
StackSwap's answer:
Most SaaS spend tools — Vendr, Zylo, Productiv, BetterCloud — require integrations with billing, SSO, or HRIS before they tell you anything. They're heavyweight onboarded platforms. StackSwap is the opposite: drop in your tool list, get a structured audit in ~60 seconds, no integration. Overlap surfaced by category, with keep / replace / remove calls. It's the diagnostic step before the platform commitment, not a replacement for it.
DUMMY DATABASE's answer
Unlike other data generators, DUMMY DATABASE gives you full relational database creation, unique event simulations, advanced control over every field, built-in SQL querying, and generous free limits — so you can go from idea to test-ready data without restrictions, subscriptions, or hidden fees
StackSwap's answer:
Two reasons:
Speed. SaaS Management Platforms take 2-6 weeks to onboard and another 30-60 days to surface useful insights. StackSwap takes 60 seconds. Different product class.
Cost. SMP contracts start around $20k/yr. The free Stackscan covers most of what a founder or RevOps lead needs to start the consolidation conversation.
Honest take: if you're already running an SMP and getting value, keep it. StackSwap is the faster diagnostic, not the replacement. If you're shopping the SMP category, run StackSwap first to see what you actually need before sitting through five demos.
DUMMY DATABASE's answer
StackSwap's answer:
B2B SaaS founders, RevOps leads, and Heads of Sales / Marketing / Revenue at companies in the 10-200 employee range — typically post-seed, pre-Series-B — where the GTM stack has grown organically and nobody owns the audit. Common trigger: a board meeting where someone asks "are we paying for tools we don't use?"
Also: buyers evaluating the SaaS spend management category who want a directional read before sitting through enterprise sales cycles.
DUMMY DATABASE's answer
Began as a project for myself to be able to have custom datasets for testing purpose I've decided that it could be useful for wider audience and finalized it as a full-stack web project
StackSwap's answer:
I spent 10 years in B2B SaaS sales — BDR through Head of Revenue — selling into hundreds of mid-market and enterprise teams. I watched companies pay six figures a year for two competing data enrichment tools because nobody owned the audit and nobody wanted to fight the renewal motion.
StackSwap is the tool I would've hated to face as a vendor on the renewal call: free, fast, takes the buyer's side, names overlap by name. The category I sold in for a decade gets auditable.
DUMMY DATABASE's answer
Python, Flask, HTML, CSS, Bootstrap, Redis, PostgreSQL, JavaScript
StackSwap's answer:
Next.js 14 (App Router) on Vercel, TypeScript, Supabase (Postgres + Auth + Storage), Stripe for billing, Anthropic's Claude API for LLM-assisted analysis, Sentry for observability.
Built deliberately on a thin stack — the irony of running a tool-overlap audit on 30 SaaS subscriptions wasn't lost on me.
