About Vessel and Codility

In their own words, as submitted to SaaSHub.

Vessel
Codility

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...

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.

  • 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

Questions & Answers

As answered by people managing Vessel and Codility.

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.
