"Webfuse is the world’s first web augmentation platform, allowing you to extend, automate, edit, and share any website through virtual web sessions

Utilizing an advanced virtualization layer, Webfuse creates isolated, controlled, and customizable environments known as Virtual Web Sessions.

Core Capabilities of VWS(Virtual Web Session):

  • Session Sharing: Allow multiple users to securely join and interact within the same virtual web session.

  • Automation API: Programmatically manage and interact with virtual sessions to automate repetitive tasks or integrate with other systems.

  • Virtual Participant Functionality: Utilize automated scripts or ""virtual users"" to perform actions within sessions.

  • Extensibility: Leverage session events/actions and virtual web extensions to add custom logic and features to the virtual sessions.

  • Session Recording: Capture sessions for training, troubleshooting, or compliance verification purposes.

  • Content Masking: Automatically obscure sensitive data fields within sessions to protect information during observation or recording.

  • Audit Logs: Maintain detailed logs of activities within virtual sessions for review and analysis.

  • Advanced Security Features: Includes configurable options such as Cookie Guard, participant authentication/verification, additional request/response header injection, and a Lockdown App add-on for enhanced restrictions."

Questions and Answers

As answered by people managing Violentmonkey and Webfuse.

Who are some of the biggest customers of your product?

Webfuse's answer:

Due to confidentiality agreements and enterprise privacy, we do not publicly list customer names without consent. That said, Webfuse is actively used by:

  • Multiple Fortune 500 enterprises
  • Leading global consultancies
  • Enterprise CX and R&D teams
  • Regulated organizations in finance and healthcare

What makes your product unique?

Webfuse's answer:

Webfuse introduces a new category in the web ecosystem—Web Augmentation Platforms. Unlike traditional tools that require code changes, browser extensions, or remote browsers, Webfuse uses Virtual Web Sessions to let you modify, automate, and collaborate on any web app instantly—without altering its source or requiring user installation. This opens up unprecedented flexibility while preserving performance, security, and compliance.

Why should a person choose your product over its competitors?

Webfuse's answer:

Webfuse offers a combination of power and simplicity:

  • No code access required – works with any app, even third-party ones.
  • Real-time UI & workflow changes – ideal for fast-moving teams and prototyping.
  • Built-in security & observability – including audit logs, session recordings, and role-based access.
  • Deep extensibility – via APIs, extensions, and automation tools. It's trusted by global enterprises not just for what it does, but for how easily and securely it does it.

How would you describe your primary audience?

Webfuse's answer:

Our primary audience includes:

  • Developers seeking to extend or remix web apps without backend access.
  • Innovation teams looking to prototype internal tools and overlays quickly.
  • Customer support, training, and QA teams who need to co-browse, record, or monitor interactions.
  • Enterprises requiring secure, auditable ways to control and automate interactions with existing systems.

What's the story behind your product?

Webfuse's answer:

Webfuse was born from a frustration with the rigidness of today’s web. Many teams rely on third-party apps they can't change, or legacy systems too slow to evolve. Inspired by remix culture (think: the mixtape era), Webfuse reimagines the browser as a programmable canvas—letting developers extend, automate, and collaborate on any app instantly. It’s about empowering teams to build on top of the web, not wait on it.

Which are the primary technologies used for building your product?

Webfuse's answer:

Webfuse is built on a stack designed for performance, security, and flexibility:

  • Go low-latency, sandboxed virtualization and rewriting engines.
  • Node.js for API orchestration and extension systems.
  • PostgreSQL, Redis, and S3-compatible storage for session data and asset handling.
  • Kubernetes & Terraform for scalable cloud and on-prem deployments.
