Testsigma
Natural language test automation for web, mobile and API with a self hosted open source edition
As of 31 August 2026, Testsigma is free to use. Test automation where steps are written as English sentences rather than code, covering web, native mobile and APIs from one suite. Softwr lists it under Testing. Testsigma is available on Web, iOS, Android, Linux.
Overview
What Testsigma does
Testsigma lets testers write steps as plain sentences, such as clicking a named button or verifying text, which the platform maps onto Selenium and Appium drivers underneath. One project can hold web, Android, iOS and API tests, and the same test data can be reused across them. Execution runs on Testsigma's cloud device and browser grid or on your own grid. The distinguishing decision is the open source community edition, released under an open licence and installable with Docker. Every other vendor in low code test automation sells only a hosted product, so the buyer sees a curated demo and then signs. With Testsigma an engineer can install it, point it at the real application, and find out over a fortnight whether the natural language layer holds up on a complicated form or falls apart. That changes the risk profile of the purchase more than any feature comparison does. It sells to QA teams in mid sized companies, heavily in India and the United States, who want one tool rather than separate Selenium and Appium stacks. The trade off is maturity. The natural language grammar is a constrained vocabulary, not free English, and complicated logic ends up in custom Java or JavaScript functions anyway. At that point you are maintaining code inside a proprietary editor rather than in your repository, which is a worse place for it than a plain Playwright project.
What people use it for
- A team maintaining separate Selenium and Appium suites that wants one place for web and native mobile coverage
- Organisations that must keep test data and execution on premises for regulatory reasons
- QA groups with manual testers being asked to automate without first learning Java
- Evaluating low code test automation properly before committing budget, by running the free edition against the real application

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Testsigma.
- The natural language layer is a fixed vocabulary rather than real English, so testers spend the first weeks learning which phrasings the parser accepts, which is learning a language after all.
- Anything conditional or arithmetic falls through to custom Java or JavaScript, and that code lives in the platform editor rather than your repository, where it gets no code review and no version history you control.
- The community edition lags the cloud product and is not the version the vendor demonstrates, so a self hosted evaluation can understate or overstate what you would actually buy.
- Cloud execution is billed separately from authoring seats, so a suite that grows from two hundred to two thousand tests changes the bill without anyone changing the plan.
- Support and engineering are concentrated in Indian time zones, which slows incident turnaround for teams working in the Americas.

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is the open source edition genuinely usable in production?
Yes for self hosted execution, though it trails the cloud version on newer features and you maintain the grid yourself.
Do testers need to know Selenium?
Not to write ordinary steps. They will need someone who does as soon as the suite needs custom functions or awkward waits.
Can it test native iOS and Android applications?
Yes, through Appium underneath, on the hosted device grid or your own devices.
