What StackSwap does

StackSwap is a free GTM stack audit that surfaces tool overlap, redundancy, and waste in B2B sales tech stacks. Built for founders, RevOps leads, and sales operators who need to cut SaaS spend without losing capability.

How it works

  • Drop in your current GTM stack (CRM, sales engagement, data enrichment, intent, etc.)
  • Get a structured audit showing where you're paying twice for the same capability
  • See keep / replace / remove recommendations with the cheaper alternative if it exists
  • Free to use โ€” no sales call, no demo, no integration setup

Who it's for

  • B2B SaaS founders trying to keep burn low
  • RevOps and sales ops teams running consolidation reviews
  • Heads of Sales / Marketing / Revenue tasked with cutting tooling spend
  • Buyers comparing the SaaS spend management category before committing to a heavyweight platform

Why it's different

Unlike SaaS Management Platforms (Vendr, Zylo, Productiv, BetterCloud), StackSwap is self-serve and integration-free. You don't connect billing data or wait on procurement workflows โ€” you get a directional audit in under 60 seconds. Great as a first-step diagnostic before adopting an SMP, or as a standalone tool for teams that just want to cut overlap.

Coverage

GTM tooling we score includes CRM, sales engagement, data enrichment, intent data, ABM platforms, conversation intelligence, marketing automation, customer success, and more.

Authenticator features and specs

  • Open Source
    Authenticator is open-source, which means the source code is available for review and contributions by the community. This increases transparency and security, as bugs and vulnerabilities can be identified and addressed more quickly.
  • Privacy-Focused
    The app doesn't require users to create an account, and it doesn't store any data in the cloud. This significantly reduces the risk of data breaches and ensures user data remains private.
  • Simple User Interface
    The app provides a clean and intuitive interface, making it easy for users to manage their two-factor authentication (2FA) codes without confusion.
  • Local Storage
    Authenticator stores codes locally on the device, which enhances security by eliminating the need to transmit sensitive information over the internet.
  • Cross-Platform Support
    The app is available on both iOS and Android, providing flexibility for users who switch between different mobile operating systems.

Possible disadvantages of Authenticator

  • No Cloud Backup
    Since the app stores data locally and doesnโ€™t support cloud backup, users may lose their codes if they lose access to their device or accidentally delete the app.
  • Manual Setup
    Users need to manually add their accounts, which might be less convenient compared to some other 2FA apps that offer QR code scanning and automatic account import features.
  • Limited Features
    Authenticator focuses on core 2FA functionality and lacks some advanced features found in other 2FA apps, such as password management or integration with password managers.
  • No Multi-Device Sync
    The app doesnโ€™t support synchronizing 2FA codes across multiple devices, which can be inconvenient for users who rely on multiple devices for their work or personal life.

StackSwap features and specs

  • StackBuilder
    Answer four questions. Get an opinionated GTM stack with specific tools, costs by tier, and what to skip.
  • StackScan
    Audits your GTM stack and surfaces the overlap. No sales call, no demo, no login or subscription.

Analysis of Authenticator

Overall verdict

  • Yes, Authenticator (mattrubin.me) is a good app for users seeking an effective, no-frills two-factor authentication solution. Its open-source nature adds an extra layer of trust for those concerned about privacy and security.

Why this product is good

  • Authenticator (mattrubin.me) is considered a good choice because it is a free, open-source app that offers a straightforward and user-friendly two-factor authentication experience. It securely stores and generates time-based one-time passwords (TOTPs) which enhance the security of various online accounts. The app's simplicity, reliability, and focus on privacy are widely appreciated.

Recommended for

    Authenticator (mattrubin.me) is recommended for individuals and professionals who need a reliable and easy-to-use solution for managing two-factor authentication codes across multiple accounts. It's ideal for users who value open-source software and prioritize security without the need for additional features commonly found in more complex applications.

Analysis of StackSwap

Overall verdict

  • Limited independent information is available about StackSwap (stackswap.ai), so a confident assessment of its quality, security, and reliability cannot be made without further research directly from official sources, user reviews, and independent audits.

Why this product is good

  • Insufficient verified public data exists to confirm the platform's legitimacy, security practices, or track record.
  • Crypto and DeFi-related platforms carry inherent risks, so any swap or exchange service should be vetted carefully before use.
  • No confirmed information on regulatory compliance, audit history, or team transparency was available at the time of this assessment.
  • Users should check for smart contract audits, community reputation, and liquidity/volume metrics before trusting the platform with funds.

Recommended for

  • Users who are comfortable conducting their own due diligence before using a lesser-known crypto/DeFi platform.
  • Not recommended for beginners or those seeking a well-established, thoroughly vetted swap service without additional research.
  • Individuals who prioritize checking audit reports, team credibility, and community feedback prior to using new platforms.

Questions & Answers

As answered by people managing Authenticator and StackSwap.

What makes your product unique?

StackSwap's answer:

Most SaaS spend tools โ€” Vendr, Zylo, Productiv, BetterCloud โ€” 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.

Why should a person choose your product over its competitors?

StackSwap's answer:

Two reasons:

  1. 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.

  2. 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.

How would you describe the primary audience of your product?

StackSwap's answer:

B2B SaaS founders, RevOps leads, and Heads of Sales / Marketing / Revenue at companies in the 10-200 employee range โ€” typically post-seed, pre-Series-B โ€” 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.

What's the story behind your product?

StackSwap's answer:

I spent 10 years in B2B SaaS sales โ€” BDR through Head of Revenue โ€” 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.

Which are the primary technologies used for building your product?

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 โ€” the irony of running a tool-overlap audit on 30 SaaS subscriptions wasn't lost on me.
