Bertha Frontend Tester
Test every journey before your users do.
Bertha Frontend Tester is a comprehensive QA tool for React applications. It uses AI to generate test journeys by analysing your pages and source code, records and replays real user flows with variable test data, and surfaces bugs through a full GUI dashboard — exporting findings for Claude Code or straight into Jira with screenshots. It keeps the portfolio's own frontends honest, and powers client QA engagements.
The layer
Act. Bertha Frontend Tester sits in the build-and-ship loop — the quality gate that lets you act on a release with confidence.
The problem
Frontend QA is slow, brittle and manual. Writing and maintaining end-to-end tests by hand can’t keep pace with how fast modern React apps change, so bugs reach users that a good journey would have caught.
What it does
Bertha Frontend Tester generates test journeys with AI from your actual pages and source, records and replays real flows with realistic persona data, and routes every bug it finds into Jira or Claude Code — all from one cross-platform GUI. It discovers API surface from Kong exports and turns QA from a bottleneck into an automated, intelligent step.
How it’s used
A proprietary Agencie.io Labs tool used to harden the portfolio’s own frontends and to power hands-on client QA engagements — the testing discipline behind shipping products people trust.
