Questions & Answers

As answered by people managing FaceSearch.app and Keylight.dev.

Why should a person choose your product over its competitors?

FaceSearch.app's answer

It combines precision, speed, simplicity, and privacy in one intuitive tool

Keylight.dev's answer:

My goal is to make all apps work with Keylight. So all of your licenses, from any types of apps, is going through Keylight for analytics, customer portal, support, ...

Most licensing tools are bundled into a payment provider. Keylight is built as an independent licensing layer.

That means you can change payment providers, sell through multiple platforms, or change your pricing model without rebuilding licensing inside your app.

It also gives developers a ready-made SDK and dashboard instead of requiring them to build and maintain their own licensing backend.

What makes your product unique?

FaceSearch.app's answer

FaceSearch.app stands out by offering instant, AI-powered face recognition that searches public web sources with high accuracy with GUARANTEED RESULTS.

Keylight.dev's answer:

Keylight keeps app licensing separate from payments. You can use Stripe, Paddle, Lemon Squeezy, Polar, Gumroad, or your own checkout without tying your app to one provider.

It handles license keys, device activations, trials, free tiers, offline access, grace periods, and signed license state through one SDK.

How would you describe the primary audience of your product?

FaceSearch.app's answer

FaceSearch.app primarily serves journalists, investigators, security professionals, and everyday users who need to verify identities, trace images, or detect impersonations quickly and securely.

Keylight.dev's answer:

Keylight is primarily built for independent developers and software companies selling apps directly to customers.

Its main audience includes:

macOS and iOS developers Web app and SaaS developers Developers selling outside app stores Teams migrating from a payment provider’s built-in licensing Developers who need trials, device limits, offline access, and license analytics

What's the story behind your product?

FaceSearch.app's answer

FaceSearch.app was created to make visual identity verification accessible to everyone—bridging the gap between advanced AI image analysis and everyday online safety needs, born from the growing demand for trust and transparency on the web.

Keylight.dev's answer:

Keylight started because I kept rebuilding the same licensing systems for different apps: license keys, trials, activations, offline access, device changes, and all the edge cases that come with them.

I also did not want licensing to be controlled by whichever payment provider an app happened to use.

So I built Keylight as a standalone layer between the app and the payment provider. Payment platforms send events to Keylight, and the app receives one consistent license state through the SDK.

Which are the primary technologies used for building your product?

FaceSearch.app's answer

The platform is built using advanced facial recognition AI models, computer vision frameworks, and scalable cloud infrastructure optimized for privacy and real-time search.

Keylight.dev's answer:

Swift and Swift Package Manager for the Apple SDK Rust SDK / JS SDK / C# SDK / C++ SDK TypeScript React Next.js Stripe Connect and payment-provider webhooks Cryptographic signatures for secure, offline-capable licenses REST APIs for application and provider integrations

Who are some of the biggest customers of your product?

FaceSearch.app's answer

  • Investigative journalists and media organizations
  • Cybersecurity and OSINT professionals
  • Law firms and compliance teams
  • Online marketplace operators
  • Digital identity verification companies

Keylight.dev's answer:

That's confidential.

  • How offline license activation actually works
    You don't want to hand-roll Ed25519 and lease parsing. Most licensing SDKs hide this behind a couple of calls. With Keylight, for example, the offline path collapses to: activate once, then a local checkOnLaunch() that verifies the lease... - Source: dev.to / 3 months ago
  • I compared the licensing tools for my indie Mac app — the honest breakdown
    Full disclosure: I now build Keylight, so weigh this accordingly — I'm telling you the seam it's designed for, not that it wins every row. - Source: dev.to / 3 months ago
  • How to add license keys to a SwiftUI macOS app (in under an hour)
    Full docs and the free tier are at keylight.dev. If you're on Tauri or Electron instead of native Swift, the same SDK pattern exists in JS/Rust. - Source: dev.to / 3 months ago
