About Vessel and Modular JavaScript

In their own words, as submitted to SaaSHub.

Vessel
Modular JavaScript

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...

Features and specs

What each product offers, as listed by its team.

Vessel 5 features
Modular JavaScript 5 features
  • Isolation
    Dedicated GCP VM per agent: own kernel, own disk, no shared tenants
  • Security
    Cloudflare Tunnel only: no public IP, no exposed port 18789
  • Provisioning
    Web dashboard: secure provision and simple onboarding
  • Runtime
    OpenClaw (open-source always-on AI agent runtime)
  • Monitoring
    Channel connectivity, gateway health, and agent status from the dashboard
  • Improved Code Organization
    Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
  • Code Reusability
    Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
  • Scalability
    As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
  • Encapsulation
    Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
  • Improved Testing
    With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

  • Increased Complexity
    Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
  • Overhead
    For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
  • Learning Curve
    Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
  • Dependency Management
    Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
  • Performance Overhead
    Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.

Analysis

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

Vessel
Modular JavaScript

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

  • Modular JavaScript (mjavascript.com) is a solid resource for developers looking to learn best practices around modular design patterns in JavaScript, though its value depends on your current skill level and how current the content remains given the fast pace of JS ecosystem changes.

Why this product is good

  • Focuses specifically on modularity, a critical but often overlooked aspect of scalable JavaScript development
  • Covers practical patterns for organizing code, managing dependencies, and structuring larger applications
  • Can help bridge the gap between basic JavaScript knowledge and professional-grade architecture skills
  • Often includes real-world examples rather than purely theoretical concepts
  • Useful for understanding module systems like CommonJS, ES Modules, and build tool configurations

Recommended for

  • Intermediate JavaScript developers wanting to level up their code organization skills
  • Developers transitioning from simple scripts to larger, maintainable applications
  • Teams looking to establish consistent modular coding standards
  • Self-taught programmers seeking structured guidance on architecture
  • Backend or frontend developers working with Node.js or modern JS frameworks who need better module management practices

Questions & Answers

As answered by people managing Vessel and Modular JavaScript.

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 / 6 months ago
