As answered by people managing StackSwap and ClientForms.app.
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.
ClientForms.app's answer:
Frontend: Next.js 15 (React 19), Tailwind CSS Backend: Supabase (PostgreSQL, Row-Level Security) Authentication: Clerk Payments: Stripe Hosting: Vercel (Sydney region) Database hosting: Supabase (Australian data residency)
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.
ClientForms.app's answer:
Psychologists who assess ADHD and autism. Typically private practice, solo or small group (1-5 clinicians), currently using paper forms and spending hours on admin per assessment. They want something that works and is secure.
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.
ClientForms.app's answer:
Neurodivergent-first design. Most digital forms just replicate paper online. ClientForms is built specifically for ADHD and autism patients - progress bars with time remaining (helps with time blindness), softer colours instead of harsh white, sticky headers so you always know where you are. The forms are designed to reduce anxiety and improve completion rates.
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.
ClientForms.app's answer:
Most clinical software treats patients as an afterthought. ClientForms is designed specifically for neurodivergent users who are filling out the forms, progress indicators, time estimates, calmer colours, predictable layouts. One link, no signup required, works on any device. Patients just open and complete.
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.
