Zentester

Ship Fearlessly with AI-Powered Testing

As AI accelerates coding - smart, scalable testing is mission-critical. Zentester brings intelligence to every layer of the testing pyramid from unit tests to E2E flows helping developers and QA engineers deliver quality at speed.

How it works

Testing, Reimagined for Dev Teams

From scenario to test suite in minutes — no scripts, no hassle.

Define Your Test Scenario

User logs in, adds item to cart, checks out. Plain English. No selectors. No complex setup.

AI Agents Test Like Humans Think

Our agents understand your app, interact naturally, and verify everything works—from UI to API to database.

Collaborate, Review, and Ship

Review AI-generated tests, refine edge cases, and watch as tests evolve with your code. Quality becomes a team sport.

Never Enough Test Coverage? Now There Is.

The Complete Testing Pyramid

Unit tests instantly cover every function. Integration tests ensure components work together. E2E tests validate real user flows.

Built for How Teams Actually Work

Developers catch bugs while coding. QA teams automate smarter and faster. Everyone shares the same quality standards.

Intelligent Test Evolution

Tests evolve with your code automatically. Smart agents understand what changed and adapt your coverage accordingly.

Coverage That Actually Matters

AI finds your riskiest code paths first. Discovers edge cases you missed. Creates tests from actual user behavior.

Merge clean, ship faster.

Shift Left Without Slowing Down

Catch issues early without slowing your team down. Zentester helps developers and QA engineers test smarter, together.

Test While You Code

Run locally. Developers spot bugs before commit, QA validates flows early.

PR-Ready From Line One

Instant test coverage for every branch. Merge confidently, review faster.

PR-Ready From Line One-1

Fix Issues in IDE, Not Production

Catch failures as they happen. Debug early, ship clean code.

Your Testing Agents, Your Workflow

Complete, up-to-date, always-on testing no manual effort needed.

Context-Aware Intelligence

Not just files—dependencies, patterns, critical paths. Zentester agents understand your entire system.

Context-Aware Intelligence

Generate Tests in Seconds

Create comprehensive test suites faster than writing a single test manually.

Smart Test Maintenance

Code evolves? Tests adapt intelligently. Review changes, not broken tests.

Smart Test Maintenance

Find the Bugs That Matter

Edge cases, race conditions, integration issues—catch what breaks production at 3am.

Find the Bugs That Matter

“Cursor had our team stuck in an endless loop - fix one test, break three others. Zencoder actually understands our codebase. What took us a full day of back-and-forth with Cursor, Zencoder handled in 20 minutes. Adding Zentester means we now ship verified code the same day.”
