About Vessel and Mainstack.co

In their own words, as submitted to SaaSHub.

Vessel
Mainstack.co

300,000+ OpenClaw instances are currently exposed on the public internet (Shodan: port 18789). Most self-hosted setups miss the tunnel, skip the required flags, share containers. When your agent processes untrusted input and holds access to your accounts, that gap matters. Vessel provides...

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

An editorial look at what each product does well and who it suits.

Vessel
Mainstack.co

Overall verdict

  • Vessel appears to be a wellness and supplement-oriented brand, but as with any health product company, its quality depends on ingredient transparency, third-party testing, and verified customer results. Without independent lab verification and credible reviews, it's best approached with cautious optimism rather than firm endorsement.

Why this product is good

  • Focuses on wellness and health-oriented products, which appeals to consumers seeking natural or supplement-based solutions
  • May offer convenience through direct-to-consumer online ordering
  • Brand positioning suggests an emphasis on personal health and self-care
  • Potential subscription or bundled options that can offer value for regular users

Recommended for

  • Consumers interested in wellness and supplement products who do their own due diligence
  • People who prefer buying health products online directly from a brand
  • Shoppers who value convenience and are willing to verify ingredient sourcing and reviews before purchasing
  • Individuals seeking self-care or health-support routines who can consult a healthcare professional first

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 Vessel and Mainstack.co.

Which are the primary technologies used for building your product?

Vessel's answer

  • GCP Compute Engine (dedicated VMs per agent)
  • Cloudflare Tunnels (encrypted inbound, no public IP)
  • OpenClaw (open-source AI agent runtime, MIT license)
  • Next.js 14 App Router (dashboard, GCP Cloud Run)
  • Express.js (API layer, GCP Cloud Run)
  • Supabase Postgres (database and auth)
  • GCP Cloud Build (CI/CD)

What makes your product unique?

Vessel's answer

Vessel is managed hosting for OpenClaw built around privacy and security first. Most OpenClaw hosting providers share containers or expose default ports. Vessel gives every agent its own dedicated GCP VM: its own kernel, its own disk, no shared memory with other tenants. No public IP. No exposed port 18789. All inbound traffic routes through an encrypted Cloudflare Tunnel. 300,000+ self-hosted OpenClaw instances are currently exposed on the public internet. Vessel makes secure, isolated deployment the default.

Why should a person choose your product over its competitors?

Vessel's answer

Most OpenClaw hosting alternatives use shared containers or expose the default port 18789 publicly. When your agent handles client data, credentials, and sensitive correspondence, shared infrastructure introduces risks that are hard to audit and harder to explain to clients. Vessel provides kernel-level isolation per agent, Cloudflare Tunnel inbound (zero port exposure), and full lifecycle management from a web dashboard: no server configuration required.

How would you describe the primary audience of your product?

Vessel's answer

Founders, marketers, lawyers, accountants, and professionals who run OpenClaw AI agents for serious work: client research, financial data, sensitive correspondence, automated workflows that touch real accounts. They need their agent to be always-on and private, but they are not infrastructure engineers and do not want to become one. Vessel is for people who want to use OpenClaw and need a trustworthy place to run it.

What's the story behind your product?

Vessel's answer

When OpenClaw launched in late 2025, it introduced something genuinely new: a persistent AI agent runtime that connects to the platforms professionals actually use and runs around the clock. What it lacked was production-grade infrastructure. The default setup exposes port 18789 publicly and leaves users to sort out tunnels, secrets, and isolation themselves. 300,000+ instances ended up exposed on the internet as a result.

I built Vessel to fill that gap. If your agent is going to handle real work, it deserves real infrastructure: dedicated VM, encrypted tunnel, locked-down defaults, lifecycle tooling. Without requiring you to be a cloud engineer.

  • What Self-Hosting OpenClaw Actually Costs (It's Not Just the VPS)
    I built Vessel because I didn't want to be the one reading that Monday notification. Dedicated GCP VM, Cloudflare Tunnel, patches and security hardening applied. Your time costs more than that. - Source: dev.to / 7 months ago
