  • Easy Storefront & Digital Product Sales

  • Built-in Payment Processing
    Mainstack offers integrated payment solutions that support multiple currencies and payment methods, making it easy for creators and businesses to receive payments globally.

    The platform is tailored for creators, freelancers, and small businesses, offering tools like customizable link-in-bio pages, portfolio showcases, and booking features that cater specifically to their needs.
  • No-Code Setup
    Mainstack requires no coding knowledge to get started. Users can build professional-looking pages, storefronts, and booking systems using intuitive drag-and-drop or form-based interfaces.

Possible disadvantages

  • Limited Brand Recognition
    Compared to established competitors like Gumroad, Shopify, or Linktree, Mainstack is less well-known, which may cause potential users to hesitate due to concerns about reliability and longevity.
  • Feature Depth May Be Limited
    While Mainstack offers many tools in one place, each individual feature may lack the depth and advanced functionality found in dedicated single-purpose platforms like Calendly for bookings or Shopify for e-commerce.
  • Limited Third-Party Integrations
    Mainstack may not offer as many integrations with popular third-party tools (e.g., email marketing platforms, CRMs, analytics tools) compared to more established competitors.
  • Smaller Community & Support Resources
    As a relatively newer platform, Mainstack has a smaller user community, which means fewer tutorials, forums, and peer-generated resources available for troubleshooting and learning.
  • Scalability Concerns
    While suitable for individual creators and small businesses, Mainstack may not offer the robust infrastructure and advanced features needed by larger businesses or those experiencing rapid growth.

Analysis

Overall verdict

  • OnlyFlights (time2pack.app) appears to be a useful travel-focused tool for finding and comparing flights, but as with any travel service, its value depends on your specific needs and how it compares to established booking platforms. Without extensive independent reviews, it's best treated as a helpful supplementary option worth trying alongside trusted comparison sites.

Why this product is good

  • It focuses specifically on flights, which can streamline the search process for travelers who only need airfare
  • Flight-focused tools often provide cleaner interfaces without the clutter of hotel and package upsells
  • May offer competitive fare comparisons that help you spot deals across multiple airlines
  • Convenient for quick trip planning when you want to check prices and timing without extra steps

Recommended for

  • Frequent flyers who want a dedicated flight search tool
  • Budget-conscious travelers comparing airfares across carriers
  • Solo travelers or those who book flights separately from accommodations
  • People who prefer a simple, focused booking experience over bundled travel packages

Overall verdict

  • Mainstack is a solid all-in-one platform for creators, freelancers, and digital entrepreneurs in Africa (and beyond) who want to sell digital products, accept payments, and manage their online presence without needing separate tools for each function.

Why this product is good

  • Combines multiple tools (storefront, invoicing, payment links, link-in-bio) into a single dashboard, reducing the need for multiple subscriptions
  • Built with African creators and businesses in mind, supporting local payment methods and currencies which many global platforms lack
  • Simple, user-friendly interface that doesn't require technical or design skills to set up a professional-looking store or page
  • Supports selling digital products, services, and even physical goods with integrated payment collection
  • Offers analytics and customer management features to help creators track sales and grow their audience
  • Relatively low fees compared to piecing together multiple Western-centric SaaS tools that may not support local payments well

Recommended for

  • African creators, coaches, and freelancers looking to monetize digital products or services
  • Solopreneurs who want an easy way to accept payments locally and internationally without complex setup
  • Content creators needing a simple link-in-bio and storefront solution combined
  • Small business owners who want to send invoices and collect payments in one place
  • Individuals just starting out online who don't want to invest in multiple separate platforms (e.g., Shopify + Stripe + Linktree)

Questions & Answers

As answered by people managing OnlyFlights and Mainstack.co.

Why should a person choose your product over its competitors?

OnlyFlights's answer

You should choose OnlyFlights over other apps because it’s fast, private, and stress-free. Unlike some flight apps, it doesn’t ask you to create an account or show you annoying ads. It gives you just what you need - like real-time flight updates, delay alerts, and a clean travel log - without any extra clutter. Plus, it’s really affordable if you want to track more than two flights. Perfect for travelers who want a simple tool that just works.

What makes your product unique?

OnlyFlights's answer

OnlyFlights is unique because it’s super simple and easy to use. You don’t need to sign up or deal with ads, and it doesn’t track your data. It focuses only on flight tracking, with clean design and useful features like live flight alerts, a countdown to your next flight, and a travel history log. It’s made for people who just want to track flights without any extra noise.

How would you describe the primary audience of your product?

OnlyFlights's answer

The primary audience for OnlyFlights is travelers who want a simple and reliable way to track their flights. This includes frequent flyers, casual travelers, flight crews, and even people picking someone up from the airport. These travelers care about staying updated but don’t want to deal with ads, sign-ups, or complicated apps.

What's the story behind your product?

OnlyFlights's answer

The story behind OnlyFlights started with Kate and Alex, the creators of the Time2Pack app. At first, they added a flight tracking feature inside Time2Pack, just to help travelers stay more organized. But soon, users began asking for a separate app that focused only on flight tracking. So, after getting lots of feedback, they decided to build OnlyFlights as a standalone app - simple, focused, and designed just for tracking flights without distractions.
