What each product offers, as listed by its team.

Mainstack.co 5 features
Paperspur 5 features
  • All-in-One Platform
    Mainstack combines multiple business tools into a single platform, including link-in-bio pages, digital storefronts, payment processing, and booking — reducing the need for multiple subscriptions and integrations.
  • Easy Storefront & Digital Product Sales
    Users can quickly set up digital storefronts to sell products, services, courses, and digital downloads without needing technical expertise or a separate e-commerce platform.
  • 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.
  • Creator-Focused Design
    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.
  • Clean, minimalist interface
    Paperspur appears to offer a distraction-free writing environment that focuses on the content rather than cluttered menus, which can help users concentrate on writing tasks.
  • Simplicity for beginners
    The straightforward design makes it accessible to users who may not be tech-savvy or who prefer simple tools over feature-heavy alternatives.
  • Fast and lightweight
    Simpler platforms like this tend to load quickly and use fewer system resources compared to bloated word processors or content management systems.
  • Focused feature set
    By not trying to be everything to everyone, the tool likely does a good job at its core purpose, whether that be writing, publishing, or organizing content.
  • Potentially lower cost
    Niche or smaller platforms often have more affordable pricing tiers compared to major competitors with extensive feature sets.

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 Mainstack.co and Paperspur.

What makes your product unique?

Paperspur's answer:

Most tools focus on just one utility—Bitly for links, DocSend for document analytics, DocuSign for contracts, and WeTransfer for temporary file sends. Paperspur unifies all these into a single, premium, privacy-first dashboard. Furthermore, our SpurShare feature is unique: it allows zero-storage browser-to-browser P2P file transfers up to 100MB via WebRTC. The files stream directly between devices and never touch our servers, providing absolute security and privacy with zero trace.

Why should a person choose your product over its competitors?

Paperspur's answer:

Cost Efficiency: Instead of paying $150+/month for DocSend or DocuSign, you get PDF gating, contract signing, and data rooms in one place for a fraction of the cost. Absolute Privacy: With WebRTC P2P sharing and AES-256 encrypted vaults, you retain total ownership. We host data in the EU and do not sell user analytics. Actionable Analytics: Get visual page-by-page reader focus timelines and heatmaps so you know exactly which sections of your proposal or pitch deck captured a prospect's attention. Developer Integration: Custom branded domains, webhook configurations, and API keys are built-in from day one.

How would you describe the primary audience of your product?

Paperspur's answer:

Founders & Startups: Pitching investors, secure deck sharing, and pre-sign NDA collection. Sales & Account Executives: Sending proposals, contracts, and marketing collateral while tracking buyer engagement. Privacy-First Professionals (HR, Legal, Finance): Securely sharing onboarding material, compliance forms, or financial assets under AES-256 encryption. Developers: Seeking programmatic control over shortened links, custom domains, and signature workflows.

What's the story behind your product?

Paperspur's answer:

I built Paperspur out of frustration with expensive software bills and data privacy concessions. I found subscribing to multiple expensive SaaS platforms to simply share pitch decks and sign contracts. I realized I could build a unified, security-first document workspace. During development, to solve the massive cloud storage overhead of temporary user file transfers, I built a WebRTC chunking relay. This allowed users to transfer files up to 100MB directly browser-to-browser (SpurShare), keeping our cloud storage bills at $0 and user data completely private.

Which are the primary technologies used for building your product?

Paperspur's answer:

Backend: FastAPI (Python), WebSockets (for WebRTC signaling and ICE relays), PostgreSQL SQLite, and Redis. Frontend: Vanilla HTML5, CSS3 (with responsive custom properties), and native Javascript (using browser WebRTC APIs and pdf.js for document rendering and focus tracking). Self-Hosting: Docker and Docker Compose.

Who are some of the biggest customers of your product?

Paperspur's answer:

Paperspur is currently in public beta, focusing on early adopters:

Seed and pre-seed startup founders using it for secure fundraising pitch decks. Independent real estate brokers distributing disclosure booklets and collecting digital contract signatures. Creative design agencies sharing drafts and tracking client review durations. Boutique consulting firms using secure vaults for confidential strategy sharing.
