Manta vs testRigor
Both let you describe tests in plain English instead of code. The difference is what happens before that: testRigor test cases — whether written by hand or bootstrapped by its AI from user behavior, app crawls, or prompts — still become a fixed suite someone reviews and maintains, across web, mobile, and desktop. Manta explores your web app continuously with no suite to maintain — mapping flows and catching breakage with no test written — and plain-English checks are an added layer. Choose testRigor for cross-platform plain-English test suites; choose Manta if you want coverage without a suite to maintain.

Where Manta wins
- Autonomous exploration — Manta maps flows and finds bugs with zero tests written.
- Coverage grows every run; testRigor only covers the cases someone wrote.
- Finds breakage in flows nobody thought to describe.
- First useful results from a URL, before any test authoring.
- A navigation map of your app's real structure, built from the run.
Where testRigor wins
- One plain-English syntax across web, native mobile, and desktop apps.
- AI-assisted test generation — can draft cases from user behavior, app crawls, or prompts.
- Built-in handling for email, SMS, and 2FA verification steps.
- Very expressive assertions — you can specify exact expected behaviour in detail.
- Reusable rules and a large library of pre-built commands.
- CI/CD integration and parallel execution available today.

What testRigor is
testRigor lets you write automated tests in plain English — "click 'Sign up', enter a valid email, click 'Continue'" — instead of code, and run them across web, native mobile, desktop, and API. It has strong built-in support for the annoying parts of end-to-end testing: email and SMS verification, 2FA, reusable rules, and a large command library. Tests are resilient to UI change because they're expressed in intent rather than selectors.
It's one of the most capable plain-English testing tools available, and its generative-AI features can draft test cases from production user behavior, app crawls, or text prompts rather than requiring every one to be typed by hand. Either way, the result is a fixed suite of test cases a team reviews and maintains.
What Manta is
Manta is an autonomous testing agent for web apps. Point it at a URL and it explores like a user, builds a behavioural model of the app, and reports what broke — with screenshots and reproduction steps — before any test is written. When you know a specific flow must keep working, you describe it in plain English and Manta turns it into a repeatable check. The autonomous testing guide explains the difference in full.
How they actually differ
| Manta | testRigor | |
|---|---|---|
| How coverage starts | Autonomous exploration — no test written | Write or AI-generate each test case, then maintain the suite |
| Coverage growth | Every run reaches more of the app | Only the cases someone wrote |
| Finds the unexpected | Yes — explores unwritten flows | No — runs the written set |
| Platform coverage | Web apps | Web + mobile + desktop + API |
| Output | Findings + a navigation map of the app | Pass/fail per authored test |
| CI/CD | On the roadmap | Available today |
Where Manta pulls ahead
It writes no tests. This is the core distinction: testRigor — even with AI-assisted generation — still produces a fixed suite of test cases someone reviews and maintains; Manta removes the suite entirely for broad coverage. You get regression signal on flows nobody described.
Coverage that grows on its own. Every run maps more of the app. A written suite — plain English or not — only ever covers what someone wrote, which is the problem when features arrive faster than tests.
A map, not just results. Manta's navigation map shows your app's real structure and where coverage stops — see how to read it.
Where testRigor is the stronger choice
- Cross-platform. Web, native mobile, desktop, and API in one plain-English syntax is something Manta doesn't offer.
- AI-assisted authoring. Its generative-AI features can draft test cases from user behavior, app crawls, or prompts — a faster starting point than typing every case by hand.
- Email / SMS / 2FA testing. Built-in tooling for verification steps is more complete.
- Very detailed assertions. If you want to specify exact expected behaviour step by step, testRigor's language is expressive.
- CI/CD today. Available now, while Manta's API triggers are still coming.
Using them together
Use testRigor for detailed, cross-platform test cases — especially anything involving mobile, desktop, or verification flows — and Manta for autonomous web coverage and fast regression feedback across everything else.
The bottom line
If your priority is authoring tests in plain English across many platforms, testRigor is excellent at exactly that. If your priority is not authoring them — getting coverage that explores and adapts on its own, with plain-English checks only where you need precision — that's Manta.
