About Vessel and Modify

In their own words, as submitted to SaaSHub.

Vessel
Modify

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
Modify 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
  • No-code website modifications
    Modify allows users to make changes to their websites without needing to write code, making it accessible for non-developers who want to customize their web presence quickly.
  • Easy A/B testing and personalization
    The platform enables users to run A/B tests and personalize website content for different audiences without requiring developer involvement, speeding up optimization efforts.
  • Quick deployment
    Changes can be deployed rapidly through Modify's interface, bypassing the traditional development cycle and reducing time-to-market for website updates and experiments.
  • Visual editor
    Modify provides a visual editor that lets users point-and-click to make changes on their site, making it intuitive and reducing the learning curve for new users.
  • No impact on site codebase
    Since modifications are applied as an overlay rather than directly changing the source code, the original codebase remains clean and unaffected, reducing the risk of breaking existing functionality.

Possible disadvantages

  • Limited awareness and community
    Modify is a relatively niche tool with a smaller user base compared to established competitors like Google Optimize or Optimizely, which means fewer community resources, tutorials, and third-party integrations.
  • Performance concerns
    Applying modifications via a third-party script layer can introduce additional page load time or cause flickering effects as changes are rendered on top of the original page content.
  • Limited customization depth
    While the no-code approach is convenient for simple changes, more complex modifications or deeply integrated features may still require developer intervention, limiting what can be achieved through the platform alone.
  • Dependency on third-party service
    Relying on Modify means your website changes are dependent on their service uptime and continuity. If the service goes down or shuts down, applied modifications could be lost.
  • Potential SEO implications
    Client-side modifications applied via JavaScript overlays may not be fully recognized by search engine crawlers, which could lead to discrepancies between what users see and what gets indexed.

Analysis

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

Vessel
Modify

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

  • Modify (modifyhq.com) is a solid choice for marketing teams that want to personalize website content dynamically without heavy engineering support. It's particularly strong for conversion rate optimization and ABM-style personalization, though it may be overkill for very small sites with low traffic.

Why this product is good

  • Allows real-time website personalization based on visitor attributes like UTM parameters, referral source, location, or ad campaign
  • No-code / low-code editor makes it accessible to marketers without developer resources
  • Integrates with common ad platforms and CRMs to tailor messaging to specific audience segments
  • Useful for account-based marketing (ABM) campaigns by customizing landing pages for target accounts
  • Provides analytics to measure the impact of personalized content on conversion rates
  • Faster iteration cycle for A/B testing and content variation compared to manual dev-driven changes

Recommended for

  • Marketing teams running paid ad campaigns who want tailored landing pages per audience segment
  • B2B companies doing account-based marketing (ABM) needing personalized experiences for target accounts
  • Growth and conversion optimization teams looking to increase landing page conversion rates
  • Companies without large engineering teams who need a no-code personalization solution
  • Mid-to-large businesses with sufficient traffic to justify investment in personalization tools

Questions & Answers

As answered by people managing Vessel and Modify.

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
