Prices are in US dollars as each vendor publishes them, or as a buyer-data source reports them where the vendor only quotes through sales. "Not verified" means we couldn't confirm it. For every tool we track, see AI QA testing pricing, compared and the alternatives hub. For coded frameworks and low-code platforms too, see test automation tools compared.

Frequently asked questions

What are the best AI testing tools in 2026?

It depends on how you want to work. Momentic, QA.tech, TestOptim AI and TestSprite explore a running app and write the tests for you. Bug0 and QA Wolf write, run and maintain the tests for you, with engineers to call on. Katalon, mabl, Rainforest QA, Testim, testRigor and Testsigma give your team an editor to build tests, with AI features to help. Applitools adds AI screenshot comparison to the tests you already have. Pick the kind first, then compare price, free access and the platforms you need to test.

Which AI testing tools can I try for free?

On our last check you could start without paying on Momentic, TestSprite, Katalon, mabl, Testim, testRigor, Testsigma and Applitools. Free access differs a lot: credit caps, run limits, time-limited trials and plans for public projects only. TestOptim AI has a 7-day Solo trial (a card is needed to start).

Which AI testing tools support native mobile apps?

Momentic, QA.tech, QA Wolf, Katalon, mabl, testRigor, Testsigma and Applitools support native iOS or Android apps. TestOptim AI and TestSprite don't support native mobile apps. We couldn't verify native mobile support for Bug0, Rainforest QA and Testim.

Which AI testing tools only quote prices through sales?

QA.tech, mabl, Rainforest QA, Testim, testRigor and Testsigma price their paid plans through sales. mabl, Testim, testRigor and Testsigma have a free trial or plan to start on first. QA.tech and Rainforest QA need a sales call to get started. TestOptim AI publishes its prices and needs no sales call for its self-serve plans: Solo $19, Startup $49 and Growth $149 a month, with Enterprise on request.

How did you choose and check these tools?

We picked the established products that use AI to write, run or check tests and that teams most often shortlist against each other. Open-source frameworks, waitlist-only products and newer tools are on our alternatives hub. Each price links to its sources and shows when we checked it. TestOptim AI is our own product, so we list its gaps from the same ratings we give every other tool, and order the list by how each tool works, not by preference.
