tldr: Testsigma is an AI-powered, codeless test automation platform that covers web, mobile, desktop, API, and Salesforce testing from a single interface. The main draw: you write tests in plain English, and AI agents handle the maintenance. It's not an execution grid like BrowserStack or LambdaTest. It's the full stack, from test creation to self-healing.
Introduction
Testsigma is a codeless test automation platform based in San Francisco, founded in 2019. The pitch: one tool that handles test creation, management, execution, and maintenance across web, mobile, desktop, and API. No code required.
That "no code" part is what separates it from most of the testing landscape. Tools like Selenium and Appium need developers. Cloud grids like BrowserStack and LambdaTest are great at running your tests, but you still need to write them first. Testsigma is trying to own the entire workflow.
As of 2026, the platform leans heavily into agentic AI, with five specialized agents that generate, run, analyze, heal, and optimize tests. More on that in our Testsigma AI guide.
The NLP engine
This is the feature that gets Testsigma the most attention. Instead of writing driver.findElement(By.id("login")).click(), you write "Click on Login button." The platform interprets the intent and executes it.
It sounds gimmicky until you see the effect on team dynamics. Manual testers who've never written a line of code can create automated tests on day one. That removes the bottleneck where every test has to route through an SDET or developer. For teams where QA headcount outweighs engineering, this changes the math on automation ROI.
What you can test
Testsigma covers a wider range than most codeless platforms:
- Web: Chrome, Firefox, Safari, Edge across 800+ browser/OS combinations.
- Mobile: Native, hybrid, and mobile web apps on 2,000+ real iOS and Android devices.
- Desktop: Windows and macOS application testing (Enterprise plan only).
- API: REST API functional testing with JSON schema validation and contract testing.
- Salesforce & SAP: Specialized support for enterprise application testing.
- Visual regression: Built-in screenshot comparison across browsers.
- Accessibility: WCAG 2.2 compliance checking (Level A, AA, AAA).
The device count is smaller than BrowserStack's 30,000+ or LambdaTest's 3,000+. If your testing matrix requires hundreds of obscure device combinations, Testsigma may not cover them all. For most teams, 2,000+ devices handles the common scenarios.
AI agents
Testsigma deploys five specialized AI agents. The short version:
- Generator: Creates test cases from Jira tickets, Figma files, live apps, or plain English prompts.
- Runner: Parallel execution across devices and browsers.
- Analyzer: Diagnoses failures and separates real bugs from environment noise.
- Healer: Auto-fixes broken locators when the UI changes. This is the standout. Users report 90% less maintenance.
- Optimizer: Flags redundant tests and coverage gaps to keep suites lean.
The Healer is the one that sells the platform. Broken locators are why most teams give up on automation, and Testsigma is one of the few tools that addresses it with actual AI, not just better selectors. For the deep dive, see Testsigma AI capabilities.
Self-healing in practice
When your app's UI changes between releases (buttons get renamed, layouts shift, elements move), traditional test frameworks break. You fix locators manually, one by one. The bigger your suite, the worse this gets.
Testsigma's Healer Agent detects those changes and adapts locators automatically. It doesn't prevent every failure, especially during major redesigns, but it handles the steady stream of minor changes that normally eat up QA hours every sprint.
Integrations
30+ integrations with CI/CD tools (Jenkins, GitHub Actions, GitLab CI, Azure DevOps), bug trackers (Jira, Linear), and communication tools (Slack, Teams). The Jira integration is two-way: failed tests create Jira bugs with screenshots, and resolved bugs can trigger test reruns. See our detailed Testsigma integrations guide.
Testsigma vs other platforms
| Feature | Testsigma | BrowserStack | LambdaTest |
|---|---|---|---|
| Approach | Codeless NLP + agentic AI | Cloud test execution grid | Cloud test execution grid |
| Test creation | Plain English, no coding | Code-based (Selenium/Playwright) | Code-based (Selenium/Playwright) |
| Browser/OS combos | 800+ | 3,500+ | 3,000+ |
| Real devices | 2,000+ | 30,000+ | 3,000+ |
| Self-healing | Yes (AI-driven) | No | No |
| Test management | Built-in | Separate product | No |
| Open source edition | Yes | No | No |
The comparison that matters: BrowserStack and LambdaTest are execution infrastructure. You bring your own tests. Testsigma is the full pipeline, from writing tests to keeping them alive. They solve different problems.
FAQs
How is this different from BrowserStack or LambdaTest? BrowserStack and LambdaTest are cloud grids for running tests you've already written. Testsigma builds, manages, runs, and maintains tests. If you have a Selenium suite and need a bigger device grid, BrowserStack is the move. If you want to stop writing Selenium code entirely, that's Testsigma's pitch.
Do I need coding skills? No. The NLP engine handles test creation in plain English. You can write custom code for edge cases, but most teams don't need to.
Is there a free version? Yes. The open source Community Edition is free. The cloud platform has a free trial. See our pricing guide for plan details.
What about test maintenance? The Healer Agent auto-adapts to UI changes. Users report up to 90% reduction in maintenance effort. Major redesigns still need manual attention.
Conclusion
Testsigma's value comes down to two things: codeless test creation that lets anyone on your QA team contribute, and AI-driven self-healing that keeps your suite from rotting. The device coverage is smaller than the big cloud grids, and the pricing requires a sales conversation. But if maintenance is killing your automation program, or your team lacks the engineering resources to write and maintain Selenium tests, Testsigma is worth a trial.
