When Browser Extension Can Improve Workflows

Workflow automation and system connectivity

  • Manual data transfer slows teams down

    Automate data capture, validation, and syncing across disconnected CRMs, ATSs, ERPs, and web tools directly in the browser, with integration into your internal systems.

  • Critical workflows happen across too many tabs

    Unify data, actions, and workflows across disjointed platforms into a single browser interface, reducing tab switching and manual transfers.

  • Third-party websites are hard to integrate directly

    Automate actions on external platforms without APIs by interacting with page content and browser-based workflows.

  • Internal data is needed inside external web tools

    Embed CRM, ATS, ERP, and analytics data directly into third-party websites, delivering internal context exactly where external work happens.

Governance, usability, and risk control

  • Compliance needs to be enforced at the point of action

    Control user actions, prevent data leaks, and enforce company policies directly within browser-based workflows.

  • Legacy web apps need better usability, not full replacement

    Upgrade existing web systems with overlays, automation, and UI enhancements, improving usability without costly full-system replacement.

Our Browser Extension Development Services

We design and develop modern extensions that connect systems, streamline workflows, and improve how teams use web applications.

Built-In Security for Browser Extension Development

Each extension we build ensures enterprise-grade data protection, integrity, and user control.

Minimal and controlled access

Apply least-privilege principles by requesting only essential permissions and restricting access to specific domains, tabs, and browser contexts.

Secure authentication and user roles

Implement SSO, token-based authentication, and role-based access control to ensure users interact only with authorized data and actions.

Safe data handling

Control how data is captured, processed, and transmitted by limiting collection, protecting sensitive inputs, and enforcing strict data flow rules.

Compliance-aware workflows

Embed compliance checks directly into user actions, including DLP controls, phishing detection, domain validation, and risk alerts.

Dependency and code security

Audit third-party libraries and extension components to eliminate vulnerabilities and prevent unsafe code execution within the browser.

Secure deployment and auditability

Enable secure distribution via browser stores or enterprise channels with version control, update governance, and logging of critical actions.

Emerline is an important part of our strategic team!

Emerline has been our technology partner since late 2012. In the early years I thought that would be a short-term gap fill until I could afford to hire my own technical team in the US. But they have consistently met the demands of our growing company and helped us build what we believe is the industry's best solution option. Emerline provides high quality work, so much so that our platform's reliability and accuracy has been mentioned by our largest customer's internal vendor survey repeatedly. The individuals we work with aren't just contractors, they are an important part of our strategic Team and we enjoy working with them every day!

My experience with Emerline has been great

The team was hired to design and develop the Echospectra mobile and web applications, as well as to integrate them with a variety of cloud services. A critical requirement was to rapidly develop the apps in an agile manner, quickly implementing important stakeholder and user feedback as it came along, and fixing any outstanding bugs. The team managed to accommodate this kind of agile, change-driven process successfully. Thanks to their rapid development approach, we've been able to build the initial app versions and then continuously iterate on them to refine our product offering and make sure it meets and exceeds customer expectations. I highly recommend them to anyone looking for a reliable partner who delivers on time and on budget.
